The BICEP2 gravitational wave announcement may have been premature, but the search has only just begun -- an interview with cosmologist Kendrick Smith.
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.
How does time stop everything from happening at once? What mechanism drives time forward, but not backward? Continue reading →
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 →
As gobsmackingly cool as it is to land on a comet AT ALL, the Rosetta craft's journey just to catch up to the flying rock was mind boggling in its own right. Trace explains the dizzying physics and helpful assist from gravity that made it possible.
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 →
When watching NASA’s historic video footage of the Apollo astronauts on the moon, it becomes clear that the alien lunar gravity was a little troublesome. The moonwalkers would often trip, stumble and wipe out as they explored the dusty landscape. … Continue reading →
Earth's gravitational pull is so powerful that it creates a small bulge on the surface of the moon.
