'Scars' in the cosmos left from the early universe could enable us to travel through time
A decades-old idea is quietly regaining attention in theoretical physics: ancient structures embedded in the universe’s fabric could reshape current understanding of time. Long dismissed as fringe ...
According to big bang theory, for the first 10 - 43 seconds of the universe's life, all the forces of nature existed as one superforce. The universe was all energy, no matter. Physicists call this ...
A strange cosmic object described by string theory could be mistaken for an ordinary black hole from far away. If these objects do exist, they could solve a long-standing paradox about black holes.
Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...
(via Sabine Hossenfelder) The BBC claims that researchers have found the first evidence for string theory, citing a recent discovery of long-wavelength gravitational waves that might indicate the ...
At a 1990 conference on cosmology, I asked attendees, who included folks like Stephen Hawking, Michael Turner, James Peebles, Alan Guth and Andrei Linde, to nominate the smartest living physicist.
