How giant atoms may help catch gravitational waves from the Big Bang
Jul 18, 2017
There was a lot of excitement last year when the LIGO collaboration detected gravitational waves, which are ripples in the fabric of space itself. And it's no wonder – it was one of the most important discoveries of the ...
How Einstein's theory of gravitation experienced a Renaissance after World War II
Jul 12, 2017
Einstein's 1915 theory of gravitation, also known as General Relativity, is now considered one of the pillars of modern physics. It contributes to our understanding of cosmology and of fundamental interactions between particles. ...
Can we ditch dark energy by better understanding general relativity?
Jun 29, 2017
A renewed suggestion that dark energy may not be real—dispensing with 70% of the stuff in the universe—has reignited a longstanding debate.
Do stars fall quietly into black holes, or crash into something utterly unknown?
May 30, 2017
Astronomers at The University of Texas at Austin and Harvard University have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful ...
'Saddle-shaped' universe could undermine general relativity
May 22, 2017
Researchers have shown how singularities – which are normally only found at the centre of black holes and hidden from view – could exist in highly curved three-dimensional space.
Solving one of nature's great puzzles: What drives the accelerating expansion of the universe?
May 15, 2017
UBC physicists may have solved one of nature's great puzzles: what causes the accelerating expansion of our universe?
Proving Einstein right using the most sensitive Earth rotation sensors ever made
May 10, 2017
Einstein's theory of gravity, also referred to as General Relativity, predicts that a rotating body such as the Earth partially drags inertial frames along with its rotation. In a study recently published in EPJ Plus, a group ...
Researcher uses math to investigate possibility of time travel
Apr 27, 2017
After some serious number crunching, a UBC researcher has come up with a mathematical model for a viable time machine.
Jupiter and the theory of relativity blamed for course changes of celestial bodies
Apr 27, 2017
In the case of solar system bodies passing close to the sun, there are two important effects playing a crucial role in the orbital evolution. One of the effects is from the general relativity and the other effect is from ...
Explaining the accelerating expansion of the universe without dark energy
Mar 30, 2017
Enigmatic 'dark energy', thought to make up 68% of the universe, may not exist at all, according to a Hungarian-American team. The researchers believe that standard models of the universe fail to take account of its changing ...
