We may never know what lies beyond the boundaries of the observable universe, but the fabric of the cosmos can tell us whether the universe is infinite or not

Through science, we are striving for objective knowledge about the universe around us. But physicists increasingly believe achieving this will never be possible

Almost all the stars that will ever exist have already been born, and they have been around long enough for life to evolve on planets that orbit them

People don't realise just how bad our antibiotic resistance problem is, says Jeanne Marrazzo, the top infectious disease specialist in the US

Research has found the universe is remarkably similar in structure to the human brain. But does this mean the cosmos has a consciousness of its own?

Whether space and time are part of the universe or they emerge from quantum entanglement is one of the biggest questions in physics. And we are getting close to the truth

One hundred years ago, we discovered there were other galaxies beyond our own. Now, we might be on the verge of another discovery: that there are other universes
