Paul M. Sutter is a research professor in astrophysics at SUNY Stony Brook University and the Flatiron Institute in New York City. He regularly appears on TV and podcasts, including 'Ask a Spaceman.' He is the author of two books, 'Your Place in the Universe' and 'How to Die in Space,' and is a regular contributor to Space.com, Live Science, and more. Paul received his PhD in Physics from the University of Illinois at Urbana-Champaign in 2011, and spent three years at the Paris Institute of Astrophysics, followed by a research fellowship in Trieste, Italy.
Physicists have discovered a strange twist of space-time that can mimic black holes — until you get too close. Known as"topological solitons," these theoretical kinks in the fabric of space-time could lurk all around the universe – and finding them could push forward our understanding of quantum physics, according to a new study published April 25 in the journal Physical Review D .
But the main problem with this is that points of infinite density can't really exist. So while general relativity predicts the existence of black holes, and we have found many astronomical objects that behave exactly as Einstein's theory predicts, we know that we still don't have the full picture. We know that the singularity must be replaced by something more reasonable, but we don't know what that something is.
And that act of curling up extra spatial dimensions at incredibly tiny scales can lead to very interesting objects.
