Scientists: Universe will 'end in a big crunch' predicting when it will happen We’ve grown up with the idea that the universe will expand forever, meaning that something called the “cosmological constant” is positive. Space keeps stretching, galaxies drift farther apart, and that seems final. A new analysis suggests that story might be wrong. It argues that expansion could slow, stop, and – far in the future – reverse. This idea posits that the cosmological constant is actually negative, not positive, as we have assumed.
Scientists Discovered a Way to Reverse Time—and Possibly Erase Mistakes In the subatomic universe of quantum physics, you can achieve things considered impossible in our flesh-and-blood physical world. Things like superposition, entanglement, and even teleportation all seem possible when things go quantum. Now, scientists from the Austrian Academy of Sciences (ÖAW) and University of Vienna are adding a kind of time travel to the list.
