Once again, scientists proved Einstein's theory of general relativity is indeed correct using a Dark Energy Spectroscopic Instrument (DESI).

A new study explores this tantalizing idea. The idea of aliens hiding in a parallel universe — though seemingly absurd — is presented as a way to bridge the gap between theoretical physics and the ...

Cosmic strings could also be detectable in the Cosmic Microwave Background (CMB) – the leftover radiation from the Big Bang ...

Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory ...
