What Is The Universe Expanding Into If Nothing Exists Beyond It

A Widely Held Theory About The Universe Expanding Has Just Been It just expands into itself It can feel like a brain teaser, but the universe is considered everything within the universe In the expanding universe, there is no pan Just dough However, the observable universe extends farther than 138 billion light-years in every direction because, for all the time space has existed, it’s also been expanding

A Widely Held Theory About The Universe Expanding Has Just Been The board is expanding in all directions that you can see There’s nothing that seems to be causing this expansion as far as you can tell – it just seems to be the nature of the chessboard The universe isn’t just expanding—it may be spinning But at 500 billion years per rotation, don't expect to feel dizzy Andrew Paul Apr 17, 2025 10:17 AM EDT Extrapolating that back in time, the Universe must have been ever smaller and denser Thus, the expansion rate can tell us how old the Universe is — how long it has been expanding for The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence But what if this was not the beginning at all?

What Is The Universe Expanding Into Extrapolating that back in time, the Universe must have been ever smaller and denser Thus, the expansion rate can tell us how old the Universe is — how long it has been expanding for The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence But what if this was not the beginning at all? Instead of starting with an expanding universe and trying to trace back how it began, we consider what happens when an overly dense collection of matter collapses under gravity This is a familiar The big bang ought to have spread energy homogeneously What explains clumps of galaxies with vast spaces between them? But if you've ever wondered exactly when it all might end, you may find it oddly comforting, or perhaps a bit unsettling, to know that someone has actually done the math As it turns out, this
