If one looks at our currently expanding universe, the fact that it is expanding means that it was smaller yesterday that it is today. If we play the expansion backwards to the beginning of the universe, it was originally very compact and maybe even centered somewhere in the current universe.

Next, if we play the expansion forward from the beginning, because of its original hot nature, being energy/matter and because of its high surface area to volume ratio, energy that was released at the perimeter should have outrun the matter, since matter is constrained to less than C. As the universe expanded the surface area to volume ratio will steadily decrease, such that more and more energy will recycle and less and less will be lost at the perimeter. Does anyone have any idea how much the original mass/energy was lost during the expansion. Does the extra journey of this energy, beyond the matter of the universe, define the limits of space?

Energy cannot be lost or expeneded,and isa eternal constant,now is the universe
really expanding?or is it that we are becoming more self aware?And thatwhat is
really expanding isour conscious perception,a deeper and expanding level of
consciousness.For me both time andspace are illusions,and have no place in
reality,whatsoever!What is expanding is our level of perception.

kind regards michael.

Hi Michael,

That's a very interesting theory, but why not Space AND perception at the same time, if they are actually the same thing?

Well, I don't believe that energy is being lost, however, the amount of useful energy is certainly dropping.

To use energy, you have to find a source of entropy, and then use that energy to drive an extropic action. And extropic actions are what we like (everything from driving to staying alive). Over time, the entropy of the universe increases, meaning there is less and less energy to tap.

BUT, there's still a lot left!

I did not mean that the energy was lost from the universe. What I meant to say, it that some energy has always been beyond the physical space that contains the matter of the universe, i.e., the stars, galaxies, dark matter etc. This "lost" energy is sort of like an energy based atmosphere that is outside the matter space of the universe and surrounds the known material perimeter of the physical universe. Does this energy "atmosphere" define the outer bounds of the universe?

The idea of the estimate, is to get a feel for the magnitude of the expanding energy atmosphere, that is and has always been steps ahead of the outer most matter of the universe. The current estimate of the mass of the universe makes it inconclusive of whether it will continue to expand or contract. The outer energy atmosphere may affect the mass/energy balance.
