Observation indicates that dark energy having an effective mass, acts as a source of antigravity, counteracting the gravitational attraction in the universe and leading to the observed accelerated expansion of the cosmos.
Effective Mass of Dark Energy Mᴰᴱ (<0), refers to a hypothetical concept that assigns a mass-like property to dark energy. Dark energy is a mysterious form of energy that is thought to be responsible for the observed accelerated expansion of the universe. Assigning it an effective mass implies that it has some influence on the gravitational behavior of the universe.
Dark Energy Generates Stronger Antigravity than Gravity, suggests that the effective mass of dark energy has an effect on the expansion of the universe that opposes the force of gravity. "Antigravity" is described as the repulsive effect of dark energy, which counteracts the attractive force of gravity, leading to the observed cosmic acceleration.
Accelerating the Cosmological Expansion, is the effect of the effective mass of dark energy is to cause the universe to expand at an accelerating rate.
A scenario in which the dynamics of a gravitationally bound system are influenced by both gravity and antigravity, due to dark energy. Inside a certain radius, gravity dominates, and the system behaves in a typical gravitationally bound manner. However, beyond a critical radius, the antigravity effect becomes stronger, potentially leading to different dynamics or behaviors for objects or systems located at those larger distances.
Gravity Dominates at Distances R < Rᶻᶢ means that within a certain distance, R < Rᶻᶢ, the gravitational attraction due to mass dominates over any potential antigravity effect. In other words, the gravitational force is stronger than any potential repulsive force caused by dark energy.
Antigravity is Stronger than Gravity at R > Rᶻᶢ beyond a certain distance, R > Rᶻᶢ, the effects of antigravity become stronger than the gravitational attraction, implies that the repulsive force or antigravity effect is significant enough to overcome gravity at these larger distances.
Gravitationally Bound System with Mass Mᴹ refers to a system of objects that are gravitationally attracted to each other due to their mass. The total mass of this system is denoted as Mᴹ.
Zero-Gravity Sphere of Radius Rᶻᶢ is the critical distance, Rᶻᶢ, beyond which antigravity becomes stronger than gravity. Inside this sphere, gravity dominates, and outside it, the antigravity effect becomes more significant.
The prevailing cosmological model known as the Lambda-CDM model, in which dark energy is responsible for the observed accelerated expansion of the universe, highlighting the idea that dark energy's repulsive influence is stronger than the attractive force of gravity, leading to the universe's expansion speeding up rather than slowing down.
The dark energy background generates stronger antigravity than the current Universe's matter gravity, accelerating the cosmological expansion.
Dark Energy Background is the pervasive and mysterious form of energy known as dark energy that is thought to fill the universe uniformly. Dark energy is hypothesized to have a constant energy density throughout space.
Generates Stronger Antigravity, Dark energy as generating "antigravity" because it has a repulsive gravitational effect. Instead of pulling things together, dark energy push them apart, countering the force of gravity.
Current Universe's Matter Gravity is the gravitational attraction caused by the visible matter in the universe. While matter exerts a gravitational pull, dark energy counteracts it with its antigravity effect.
Accelerating the Cosmological Expansion, it is primary consequence of dark energy's antigravity effect is that it causes the expansion of the universe to accelerate. In other words, galaxies are moving away from each other at an increasing rate over cosmic time.
