The End of the Universe

Our deepest galaxy surveys can reveal objects tens of billions of light years away, but there are more galaxies within the observable Universe we still have yet to reveal between the most distant galaxies and the cosmic microwave background, including the very first stars and galaxies of all. As the Universe continues to expand, the cosmic frontiers will recede to ever greater distances. (SLOAN DIGITAL SKY SURVEY (SDSS))

What Will It Be Like When We Reach The End Of The Universe?

There’s a million things we haven’t done. But just you wait.

The Universe as we know it began some 13.8 billion years ago with the onset of the hot Big Bang. Ever since that early stage, our cosmos has been expanding, cooling, and gravitating in accordance with the laws of physics. As the Universe unfolded, we passed a series of important milestones that led to the Universe we observe and inhabit today. After 13.8 billion years, on one world in an outer arm of a non-descript galaxy on the outskirts of our local supercluster, human beings emerged.
It’s been spectacular how we’ve managed to put together our entire cosmic history, from what set up and caused the Big Bang until the present day. But that leads to one spectacular question that humanity has long wondered about: what is our ultimate fate? What will it be like when we reach the end of the Universe? After countless generations of searching, we’re closer than ever to the answer.
