A chance alignment of galaxies and a touch of extreme physics was all it took for the universe to create an uncanny smiley face in deep space.
For the first time, the mass of a binary pulsar pair has been precisely measured, but it was a race against time before the extreme gravitational warping of spacetime caused one of the dense objects to blip out of view.
Time moves forward and only forward. We all know that. Or do we? A new study challenges our preconceived notions about time and posits the idea that the arrow of time could, in effect, go both ways, thanks to a mirror world we can't even see.
So-called strange stars, made of radically different stuff than ordinary matter, may finally be detectable.
Sci-fi fans who hope humanity can one day zoom to distant corners of the universe via wormholes, as astronauts do in the recent film 'Interstellar,' shouldn't hold their breath.
Many of the physics theories explained in the movie 'Interstellar' are being investigated by the world's most powerful particle accelerator, which is awesome. Continue reading →
Mass and gravity are intimately related, so it stands to reason that the link between the Higgs boson and gravity is just as fundamental -- now astronomers are looking to the stars to actually test the finer details of this relationship. Continue reading →
Gravitational waves are hard to observe, but they could have a dramatic effect on stars that we could possibly detect. Continue reading →
