Researchers say they discovered observational evidence of string theory, which could turn everything we know about the ...

Last month, the Dark Energy Spectroscopic Instrument (DESI) collective reported that dark energy is evolving—specifically ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the ...

The consequences of this quantum space-time have long been predicted by string theory, which ties it to dark energy, believed to be responsible for the accelerated expansion of the universe.

Also, the cosmic background radiation ... A piece of this string only 1.6 kilometers long would weigh more than the earth. Others have added to the theory: That symmetry still exists within ...
