Last month's BICEP2 discovery of gravitational waves is compelling evidence for the inflationary period just after the Big Bang. But what if there's another explanation? Continue reading →
Theoretical physicists may have stumbled onto a solution to the black hole "information paradox" -- what if a black hole's singularity isn't an infinitely dense point in space-time? Continue reading →
The renowned physicist has thrown the black hole "firewall paradox" into the limelight by suggesting black holes' event horizons be replaced with "apparent horizons." Continue reading →
If we could harness the energy generated by an evaporating black hole, we might be able to bridge the vast space between the stars.
Physicists have tried searching for time travelers on the Internet. But they didn't find any.
The Hubble Space Telescope's ambitious new mission to use natural gravitational lenses to magnify some of the earliest galaxies has returned its first stunning views of the depths of the Cosmos.
Pulsar astronomers scored big with the finding of a triple star system that includes a millisecond pulsar -- it could be one of the most extreme tests yet for Einstein's general relativity. Continue reading →
One of the biggest and most vexing problems in physics is how quantum dynamics and general relativity relate to one another -- but could both theories find middle-ground in a wormhole? Continue reading →
