The universe is expanding even faster than we thought until now, show the Hubble observation. The reason remains unknown. Maybe a big hole in the understanding of the fundamental laws of physics, possibly on the part of the mysterious dark energy.
An important question is, how powerful it is dark energy and whether its amount over time standing or rising, because it affects the expansion of the Universe, which tells what will with the universe eventually happen. Roughly speaking, there are three scenarios. The first says that the universe will expand still more slowly, until it will not stop, and the process will be reversed, which should lead to deforestation and re-densification of the one infinitesimal point – to be followed by a new large bang.
