The energy expelled from the Big Bang, we just haven't run out yet, and probably won't for a long time to come. And whose to say when it does run out the FE wont flip over and begin accelerating back to its starting point?
Hi this is my first post here. My brother Philip Marfuta is a grad student at Princeton University, you'll be seeing posts from him soon
, and he would tell you otherwise. See, him and his fiancee, Judy M Lau, worked on this thing called the YMAP. What's YMAP you may ask? Well it pretty much mapped the universe by using the background radiation from the Big Bang, albeit the map shows a younger version. Anyways, YMAP also showed, don't ask me how Wiki it or check princeton.org, that the universe is expanding at an
accelerating rate because of dark energy. The reason for this is because the Big Bang was caused by Dark Energy and the gravitational forces caused by matter and dark matter. When the universe was young the univser would expand really slowly, but basically, as the universe expanded the Dark Energy would gain the advantage. Gravity is stronger the more matter there is, so as the matter spread out gravitational forces weakened. This explains the accelerating expansion of the universe. The problem is we don't know what in the world Dark matter is, even worse is that we don't know what Dark Energy is, besides the points i just explained.
My point is, the only reason i would see FE accelerating upwards, is because of Dark Energy pushing it, causing a gravitational effect on us, which could work and not work at the same time its odd.
TL;DR
Dark energy makes the universe expand at an accelerating rate, which could possibly allow FE's acceleration upwards.
