A black hole devouring a neutron star: - The first ever collision detected.

The US Laser Interferometer Gravitational-Wave Observatory (Ligo) detected the first collision, dubbed GW200105, on January 5, 2020, and the wave suggested that a neutron star bigger than our Sun had been sucked in by a black hole. The black hole had a mass equal to that of nine suns.

  • Gravitational waves are 'ripples' in space caused by some of the most violent and energetic processes in the Universe. These cosmic ripples would travel at the speed of light, carrying with them information about their origins, as well as clues to the nature of gravity itself. The speed, wavelength, and frequency of a gravitational wave are related by the equation c = λ f, just like the equation for a light wave. The frequencies of gravitational wave are much lower than those of the electromagnetic spectrum, less than a hertz to a few thousand hertz at most and have much larger wavelengths – ranging from hundreds of kilometres to potentially the span of the Universe, but surprisingly they travel at the speed of light.  Gravitational waves appear as 'ripples' of low frequency space waves, ranging between a fractions of a Hertz to a few Kilo Hertz, unusually travelling at the speed of electromagnetic waves, obviously due to its medium is space. It also appears that for a 150,000 Kilometre (Km) wavelength of a Gravitational wave, its frequency would be just a little less than 2 Hertz (Hz). 


  • A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a point. This can happen when a massive star dies. A black hole forms when the centre of a very massive star collapses in upon itself. Because no light can get out, people can't see black holes. They are invisible.
  • Neutron stars are dead stars that are incredibly dense. A teaspoonful of material from a neutron star is estimated to weigh around four billion tonnes. Both objects are cosmological monsters, but black holes are considerably more massive than neutron stars. Since neutron stars are dead stars and incredibly dense, when a black hole engulfs a neutron star, the collision creates ripples in the fabric of space called gravitational waves.
  • For sound waves in air, the speed of sound is 343 m/s (no comparison with C). The wavelengths of sound frequencies audible to the human ear (20 Hz–20 kHz) are thus between approximately 17 m and 17 mm respectively. However, radio waves travel at the speed of 299,792,458 m/s in space.

    • It appears that for a just 100 Hertz (Hz) frequency of a sound wave (unmodulated), its wavelength would be 3.43 Metre (m) and its speed would be 343 m/s on Air at 20°C.
    • It also appears that for a just 100 Hertz (Hz) frequency of a Gravitational wave, its wavelength would be 2,998 Kilometre (Km) and its speed would be 299,792,458 m/s in space.
    • It appears that only the waves those can also travel in space travels at C (f.λ = C).

Healing mechanism of the body:

 

The immune system plays a crucial role in the process of wound healing.
Healing must happen by repair in the case of injury to cells that are unable to regenerate (e.g. neurons). Also, damage to the collagen network (e.g. by enzymes or physical destruction), or its total collapse (as can happen in an infarct) cause healing to take place by repair.
If you break a bone, your body immediately begins producing new cells to heal the damage. When your skin is cut, platelets in your blood clot to stop the bleeding, white blood cells remove the dead, injured cells and new healthy cells repair the damaged tissue.
When the skin is injured, our body sets into motion an automatic series of events, often referred to as the “cascade of healing,” in order to repair the injured tissues. The cascade of healing is divided into these four overlapping phases: Hemostasis, Inflammatory, Proliferative, and Maturation.
Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that. Our brain for example will not regrow damaged brain cells but can repair an area by laying down other scar-type tissue .
Heal Naturally
Sleep. The health benefits of sleep are well established, however, we frequently “get by” on very little sleep.
Drink More Water. When your body does not get enough water, it enters a state of dehydration which can lead to slower healing and increased fatigue.
Eat Nutrient Dense Foods. ...
Be Positive. ...
Exercise Routinely.

Energy prior to the formation of the Universe and my interpretation - A Summery:

Frequency is related to energy (E) as in the Planck's equation E=hv, where v=frequency (Hz) and h=6.626 070 15 x 10-34 J Hz-1 represents relationship between energy and frequency, where 'h' is plank’s constant. And, energy 'E' is equivalent to mass 'm' as in the Einstein's theory of special relativity E=mc². 

Therefore, combining these above two equations we get energy-mass (m) is related to frequency of the wave the energy-mass ('f' in Hz or 'v' s–1 in Hz).

  • frequency 'f' or 'v' of the wave is inversely proportional to the wavelength λ (Lambda), whereas, 'c' and 'h' both are constant in respective equations relevant. --> 'f'∝1/λ or, 'v'1/λ

  • 'f' or 'v' of the wave too is inversely proportional to time period 'T' s (second). --> 'f'∝1/T or, 'v'∝1/T

The derived equation from the combination of the above said equations, the frequency (v;f) of mass-energy if somehow gets changed due to the effect of relative gravity or relative speed, then the wavelength (λ) of that mass-energy would also change. 

So this would be the main consideration in the following steps.

  • The wavelength (λ) of that mass-energy  is directly proportional to the time period (T) of the wave. --> λT

In the experiments, it is observed that the time interval for 1° of phase is inversely proportional to the frequency. If the frequency of a wave is given by ‘f’, then the time tdeg (in seconds) corresponding to 1° of phase is

  • tdeg = 1 / (360f) = T / 360.

Therefore, a 1° phase shift on a 5 MHz wave corresponds to a time shift of 555 picoseconds.

  • The maximum frequency of visible light (f)=7.5 x 1014 Hz, its wavelength (λ) = 400 manometer, and its velocity v=c=3 x 1010 cm/s.  Einstein's theory of special relativity sets the absolute speed limit at which a wave can travel, which is the speed of light (c) is equal to 3 x 1010 cm/s. 

  • The maximum frequency of Gamma-rays (f) = 1024 Hz, its wavelength (λ) = <10-12 (i.e., <0.01 nanometres), and its velocity  too (v) = 3 x 1010 cm/s.  

However, when the frequency (f) of any wave reach infinite (∞), its wavelength must be zero i.e., λ = 0. If wavelength is zero, then as per the scientific understanding, it can't be a wave, as it refers that the wave has no spatial time period or, it is stable at all times.

Similarly, a singularity where gravity approach infinity, space and time cease to exist and current laws of physics cannot be applied. A no-dimensional singularity is considered to be a point form. So a question may arise, "how is it possible that the interaction of no-dimensional singularity occupy anything in three-dimensional space? (E.g. block-hole). Are no-dimensional black holes part of the 3-dimensional Universe?

Moreover, in real sense,  a simple mathematical representation of energy (E) would not be possible in that condition, as there is no event or time, absence of light due to absence of stars, even then; energy suddenly can't go vanished but most likely it converted in some other form of energy and behave like vibration - as  in the Planck's equation energy (E) is related to frequency.

Whereas, time (t) is indefinite continued progress of existence and events in the past, present, and future, in irreversible progression. It is regarded as an abstract concept, there is increasing evidence that time is conceptualized in the mind in terms of space. That is, instead of thinking about time in a general, abstract way, humans think about time in a spatial way and mentally organize it as such. Using space to think about time allows humans to mentally organize temporal events in a specific way. Therefore, for the time to exist not only existence, either in the form of energy or matter, is necessary, but both existence and events are necessary, as any existence without events, hence without time, would have no real meaning. In absence of time, Planck's equation and the equation of Einstein's theory of special relativity would cease to apply.

Rationally speaking, space too would cease to exist in absence of events, time and also light, moreover, the abstract nature of mathematics very likely to hints us that the energy (E), as in Planck's equation E=hν, likely to prevail as very high vibration frequency, that too without events, time, space and light. A singularity - where gravity approach infinity, space and time cease to exist and current laws of physics cannot be applied.

How energy behaves and what happens to it's frequency in such condition - a mathematical abstraction would probably hints us to conceptualize that frequency of such energy might have achieved infinite value, with the wavelength and it's dimension zero (0), known laws of physics would cease to operate in such condition but we can always conceptualize it though mathematical abstraction.
 

Note on Time Dilation: What actually happened in the experiment as can be seen in the relationship λ∝T. The experiment actually considered dilated wavelength and not dilated time. If the experiment is considered that it observed dilation of time then it will violate fundamental properties of time. It rather miscalculated T instead of λ, because by appropriately changing either of the value of λ or even the value of T, one will get same result. But the illegality would be considering T as gravity affected factor instead of appropriately considering λ as the gravity affecting factor. A λ can be influence by gravity and change its wavelength but none can change T with the effect of gravity as time is not something changeable by any external influence or interaction unless such changes is in the structure of the events itself, then only time comes into a relative consideration with the changeable events. Time does not participate in any eventual act rather time tracks changes in the events. So a question of changing time is not only absurd but is illegal too as per valid definition and properties of time. Time dilation necessarily needs to be wavelength dilation, when λ∝T comes in to the consideration.

Human Blood in a nutshell:

Human Blood in a nutshell:

1.  Blood is a combination of plasma and cells that circulate through the entire body; the red liquid circulates in the arteries and veins of humans carrying oxygen from the lungs to the tissues of the body and carbon dioxide vice versa. A normal oxygen level for healthy lungs falls between 80 and 100 mm Hg.

Total blood volume constitutes of:-

i.          55% plasma (composed of 90% water, salts, lipids and hormones, rich in proteins (including albumin), immunoglobulin, clotting factors and fibrinogen).
ii.          45% erythrocytes (RBC).
iii.         Less than 1% consists of leukocytes (WBC) and,
iv.         Thrombocytes (platelets).


2.   Plasma is light yellow liquid carries water, salts and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The colourless fluid part of blood in which corpuscles (cells) are suspended, more than half of the blood's volume consists of plasma, mostly made of water that contains dissolved salts (electrolytes) and proteins. Plasma cells have an indeterminate lifespan, ranging from days to months. It is frozen within 24 hours of being donated in order to preserve the valuable clotting factors. It is then stored for up to one year, and thawed when needed.

Plasma is beneficial to a wide variety of patients, trauma, shock, severe liver disease and multiple clotting factor deficiencies patients. Children and adults with cancer or leukaemia need plasma transfusions. Other users are people undergoing liver transplants, bone marrow transplants, and severe burn patients. Clotting factors for haemophilia patients are made from donated plasma. It helps boost the patient's blood volume, which can prevent shock, and helps with blood clotting.

i.        The normal range is 3.5-5.5 g/dL or 35-55 g/litre. Albumin composes 50%-60% of blood plasma proteins.

ii.       Plasma can be exchanged in the hospital or at medical facilities, the process isn't painful, and one does not need anaesthesia.

iii.       Vitamin & food to increase plasma are Vitamin A – carrot, sweet potato. Vitamin B12 – eggs, cabbage, folate rich food, Vitamin K.

3. A blood cell, called a haematopoietic cell, hemocyte, or hematocyte, is produced through haematopoiesis and found mainly in the blood. The three main types of blood cells (corpuscles) are Erythrocytes (Red blood cells or RBC), Leukocytes (White blood cells or WBC), and Thrombocytes (Platelet).

i.          Erythrocyte (RBC) is a cell that contains protein called haemoglobin, which carries oxygen from the lungs to all parts of the body.

ii.          Leukocytes (WBC) are type of immune cells that are made in the bone marrow and are found in the blood and in lymph tissue. Types of Leukocytes are granulocytes (neutrophils, eosinophils, and basophiles), monocytes, and lymphocytes (T cells and B cells). The two main types of lymphocytes are B lymphocytes and T lymphocytes. B lymphocytes make antibodies, and T lymphocytes help kill tumour cells and help control immune responses. The lifespan of white blood cells (WBC) ranges from 13 to 20 days, after which time they are destroyed in the lymphatic system. When immature WBCs are first released from the bone marrow into the peripheral blood, they are called "bands" or "stabs." Leukocytes fight infection through a process known as phagocytosis.

iii       Thrombocytes (Platelet) help form blood clots to slow or stop bleeding and to help wounds heal. They are pieces of very large cells in the bone marrow called megakaryocytes. Having too many or too few thrombocytes or having platelets that don't work as they can cause problems. The lifespan of thrombocytes is 5 to 10 days, and thus they have to be constantly replenished.

4.  Erythrocytes or red blood cell (RBC) - a type of blood cell that is made in the bone marrow and found in the blood, carries oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Their characteristics of being red, round, and like rubber give them the ability to complete their specific functions. Erythrocytes are produced in the bone marrow and sent into the circulation. At the end of their lifecycle, they are destroyed by macrophages, and their components are recycled. In a normal individual with a mean RBC lifespan of 115 days, this value may vary between 70 and 140 days.

i.             The normal range of RBC for men is 4.7 - 6.1 million cells per microliter (mcL). The normal RBC range for women who aren't pregnant is 4.2 - 5.4 million mcL. The normal RBC range for children is 4.0 - 5.5 million mcL.

ii.      A high erythrocytes (RBC) count may be a result of sleep apnoea, pulmonary fibrosis, and other conditions that cause low oxygen levels in the blood. Performance-enhancing drugs like protein injections and anabolic steroids can also increase RBC. Kidney disease and kidney cancers can lead to high RBC counts as well.

iii.              High red blood cell count, recommends a procedure or medication to lower it. In a procedure called a phlebotomy, a phlebotomist inserts a needle into your vein and drains blood through a tube into a bag or container.

iv.      A low red blood count, or anemia, can cause feelings of fatigue and weakness. When a person has a lower red blood count than is normal, their body has to work harder to get enough oxygen to the cells. A low red blood cell (RBC) count can cause a variety of symptoms and health complications.

v.          Vitamin B12 makes red blood cells, to provide vitamin B12 to your cells; you must eat foods that contain vitamin B12, such as meat, poultry, shellfish, eggs, fortified breakfast cereals, and dairy products. Your body must absorb enough vitamin B12.

vi.       Food to increase RBC are red meat, organ meat (kidney, liver), dark leafy green vegetable (spinach), dried fruits (raisin), beans, legumes, and egg yokes. 

5.   Leukocytes (White blood cells or WBC): Blood cell that is made in the bone marrow and found in the blood and lymph tissue, body's immune system; protecting the body against both infectious disease and foreign invaders. Normal white blood cells (WBC) 4.0-10.0 /μL. Food and vitamins to increase WBC are Citrus fruits, Vitamin C, zinc, poultry and lean meat.

Five types of leukocytes are, - Monocytes, Lymphocytes (B lymphocytes and T lymphocytes) and Neutrophils, Basophils, Eosinophils are collectively known as Granulocytes.

i.          Monocytes are a type of leukocyte, or white blood cell. They are the largest type of leukocyte and can differentiate into macrophages and myeloid lineage dendritic cells. As a part of the vertebrate innate immune system monocytes also influence the process of adaptive immunity. The life span of a circulating monocyte is fairly brief and most undergo apoptosis after about 24 h. Some monocytes do, however, migrate into tissues or to the sites of damage or infection where they subsequently mature into macrophages. Normal range of Monocytes: 0-10%.

ii.       Lymphocytes are type of immune cell those are made in the bone marrow and are found in the blood and in lymph tissue. They create antibodies to fight against bacteria, viruses, and other potentially harmful invaders. Unusually high or low lymphocyte counts can be a sign of disease. Most lymphocytes are short-lived, with an average life span of a week to a few months, but a few live for years, providing a pool of long-lived T and B cells. These cells account for immunologic “memory,” a more rapid, vigorous response to a second encounter with the same antigen. Normal range of Lymphocytes: 20-40%.

(a)   The two main types of lymphocytes are B lymphocytes and T lymphocytes. B lymphocytes make antibodies to attack specific viruses, bacteria, and other foreign invaders. T lymphocytes help to identify and kill tumour cells and help control immune responses.

i.        B lymphocytes or B-cells fight bacteria and viruses by making Y-shaped proteins called antibodies, which are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells. About 85% of peripheral B cells are phenotypically mature and display first-order exponential kinetics defined by a half-life of 5-6 weeks, whilst the remainder are short-lived with a life span of several days.

ii.         T lymphocytes or T-cells are one of the major components of the adaptive immune system. Their roles include directly killing infected host cells, activating other immune cells, producing cytokines and regulating the immune response. Memory T cells live for six months or less in healthy humans, whereas naive T cells can live for up to nine years. Thus, a long life is not a key characteristic of memory T cells.

(b)  Antibody, a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.

(c)   Antigen is any substance that causes your immune system to produce antibodies against it. This means your immune system does not recognize the substance, and is trying to fight it off. An antigen may be a substance from the environment, such as chemicals, bacteria, viruses, or pollen.

(d)  Bacteria, member of a large group of unicellular micro organisms which have cell walls but lack organelles and an organized nucleus, including some which can cause disease.

(e)   Viruses are infective agents those typically consist of nucleic acid molecule in protein coats, are too small to be seen by light microscopy, and are able to multiply only within the living cells of hosts.

(f)     Fungi, a group of spore-producing organisms feeding on organic matter, including moulds, yeast, mushrooms, and toadstools.

(g)   Parasites, organisms those live in or on organisms of another species (hosts) and benefit by deriving nutrients at the other's expense.

iii.        Granulocytes: Neutrophils, Basophils, and Eosinophils are white blood cells help the immune system fight off infection; they have secretory granules in its cytoplasm, so collectively they known as Granulocytes. Typically granulocytes have a role both in innate and adaptive immune responses in the fight against viral and parasitic infections.

(a)   Neutrophils kill and digest bacteria and fungi. It is a type of white blood cell, a type of granulocyte, and a type of phagocyte. A type of immune cell that is one of the first cell types to travel to the site of an infection. Neutrophils help fight infection by ingesting micro organisms and releasing enzymes that kill the micro organisms. Neutrophils are key components in the system of defence against infection. An absence or scarcity of neutrophils (a condition called neutropenia) makes a person vulnerable to infection. The average lifespan of inactivated human neutrophils in the circulation has been reported by different approaches to be between 5 and 135 hours. Normal neutrophils (ANC) count 40-80% of total white blood cells.

(b)  Basophils, appear in many specific kinds of inflammatory reactions those particularly reason allergic symptoms, contain anticoagulant heparin, which prevents blood from clotting too quickly; also contain the vasodilator histamine, which promotes blood flow to tissues. Once mature, basophils have an estimated life span of 60–70 hours. Normal range of Basophils <2%

(c)   Eosinophils, are type of disease-fighting white blood cell, condition most often indicates a parasitic infection, an allergic reaction or cancer, one can have high levels of eosinophils in blood (blood eosinophilia) or in tissues at the site of an infection or inflammation (tissue eosinophilia). Eosinophils have a circulating half-life of approximately 18 hours and a tissue life span of at least 6 days. Normal range of Eosinophils: 0.0-6.0%.

6.     Thrombocytes (Platelet) are pieces of very large cells in the bone marrow called megakaryocytes. They help form blood clots to slow or stop bleeding and to help wounds heal. The lifespan of thrombocytes is five to 10 days. Having too many or too few thrombocytes or having platelets that don't work as they can cause problems, more than 400000 platelets, a condition called thrombocytosis; having less than 150000 known as thrombocytopenia..

i.                   A normal platelet count ranges 150-400 (μL) of blood.
ii.                 Food to increase platelet- eggs, green leafy vegetable, liver, meat and cabbage.

(a)   Primary thrombocytosis, or essential thrombocythemia, can cause serious bleeding or clotting complications. These can usually be avoided by maintaining good control of the platelet count with medications. After many years, however, bone marrow fibrosis (scarring) can develop. Secondary thrombocytosis include infection, inflammatory states (for example, inflammatory bowel disease), physical stress (including the post-operative state), acute blood loss, iron deficiency anemia, post-splenectomy and underlying malignancy.

(b)  Thrombocytopenia signs and symptoms are easy or excessive bruising (purpura) superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs, prolonged bleeding from cuts.
