Planck velocity equals one Planck length per Planck time:

It seems, in 1900 Max Planck's equation was primarily E = f(λ). In 1905 Einstein promoted c = fλ.

The world over knows c is devised in the theory of special relativity, where c = fλ = √E/m.

However, according to Max Planck the velocity of electromagnetic waves, or light, is equal to one Planck length per Planck time; the limit to which photons can travel. 

(Read More... Planck Length by Max Planck.) 

• Planck time ~ 5.39×10^−44 s.
• Planck length ~ 1.61626×10^−35 m.
• c =~3x10^8 m/s.

Addressing the question, "Should we abandon the multiverse theory?"

While my intention is clear as described in my previous post wherein I have mentioned,

i.  "Physical science must be physical"

ii. "Abstract concepts are pure mathematical"

iii. "Max Planck limits (our) reality.

iv "Events invoke Time"

The above-mentioned itemized premises probably indicate that multiverse theory is abstract in its properties, like the abstractions of mathematics.

Proving these would certainly not be possible because the natural limits of our interactions are limited to three-dimensional space and, according to Max Planck, anything above Planck units would be meaningless to us.

We cannot perceive any possible event beyond our limits in the Planck length because events invoke time. So impossibility in perception means impossibility in origin of time.

Importantly, there are some entities with semi-real properties like dark energy or even dark matter and black holes, they seem to exist outside the boundaries of the Planck frequency but their only interactions with reality make them semi-real until we can establish. As they are completely real.

Quasi-realism is the meta-ethical view which claims that: Ethical sentences do not express propositions. Instead, ethical sentences project emotional attitudes as though they were real properties.

Therefore, there should be no barriers to exploring multiverse theory, just as we explore abstraction in mathematics. Such explorations may actually improve our understanding.

However, strictly speaking, such explorations need to be limited and promoted only as abstractions and not as a possible reality - as if they could never be proved or disproved - as per the definition of reality.
