O.K. now onto the subject of infinite energy in an infinite universe.
Well Space is expanding due to the cosmological constant (vacuum energy, quintessance, so on whatever you call it or think it is, it all makes up the value of Lambda. If you followed that tell me how!
). This means that there is an edge to even an infinite universe, at least from our viewpoint, it is where the 'speed' of the expansion between the viewer and another point in space (whatever it happens to be) exceeds the speed of light.
This means that even though the both viewer and the other point are 'stationary' light cannot travel from one to the other (even over infinite time). The fact that nothing can travel faster than the speed of light (don't even say Tachyons
)is not a problem since nothing is, only the distance between the two points itself is changing.
Therefore even in an infinite universe you only get to see a finite volume of space. So only the Photons from objects in this volume can reach you, so no superheating problem! This also means that the cooling of space does not mean energy is being 'lost' only that the density of the energy is decreasing, same amount of energy larger volume.
Now i'm sure you are all wondering why I wrote all this, I don't know, no idea whatsoever.
Good Luck I hope you can follow this guys I'm not sure I can
