Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, and their findings may be good news for the standard cosmological model. The new research was reported ...
Imagine standing in the emptiest place the universe has to offer, a stretch of cosmic ocean so vast that light takes tens of millions of years to cross it, and yet still finding company. That is the puzzle behind a new study ...
