Is there a “bottom” in the universe? "Absolute potential energy" thinking from "absolute position 0"
[English] [Japanese]
Suppose there is an "absolute position 0" somewhere in this universe.
"Absolute position 0" is the bottom of the universe, like the temperature of absolute 0 degrees, beyond which you can't fall.
Then, since a substance existing at a certain position has potential energy,
All matter located in outer space will have absolute potential energy.
e = mgh
Generally, potential energy is expressed by this formula. m is mass, g is acceleration, and h is position.
e = mc^2
The energy possessed by matter is expressed by this formula.
Assuming that this absolute potential energy and the energy of the substance are the same,
mgh = mc^2
In other words, it can be expressed as:
gh = c^2
Where is the assumed absolute position 0?
h = c^2 / g
g is the acceleration of matter in the universe. If we know how much we're accelerating, we can probably figure out the distance to absolute position zero.
h and g are inversely proportional; if g is small, h will be large; if g is large, h will be small.
Can it be negative?
I want to know the bottom of the universe.
