What if the Big Bang didn't begin with a singularity? This point of infinite density, which so divides physicists, could be ...

Einstein’s equations of general relativity were a wellspring from which our current view of the cosmos has flowed. That the theory continues to supply so many rich questions is part of what makes it ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

While the ΛCDM model has been a cornerstone of cosmology, it is showing its limitations as researchers seek to explain observations beyond its scope. (CREDIT: ESO/L. Calçada/spaceengine.org) The ...

Using the MUSE instrument on ESO’s VLT , a team led by Thomas Collett from the University of Portsmouth in the UK first calculated the mass of ESO 325-G004 by measuring the movement of stars within ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...

For more than two decades, radio astronomers have been hunting for a specific kind of needle in the Milky Way’s most chaotic ...
