What’s the man saying?
The pull of gravity is too weak to correlate with the 3 +1 dimension universe?
What do you do then?
Multiply the existing pull of gravity to make it equal to the necessary pull of gravity.
That will give us the correct amount of matter in the universe.
It won’t tell us anything about dimensions.
But light works in a different way.
Light will diffuse faster in proportion to the number of dimensions that exist.
In the 3 + 1 universe, the 3 dimensions gradually extend into the 4th dimension.
What happens to light when the 3 dimensions extend into the 4th?
What happens to light if there are 11 or even 25 dimensions?
Is light the key to demonstrating 11 or more dimensions?
