Some black holes may actually be tangles in the fabric of space-time, new research suggests
A new paper discusses how light interacts with theoretical objects called "topological solitons" — kinks in the fabric of space-time that look just like black holes.
If dark matter is 'invisible,' how do we know it exists?
Despite making up most of the matter in the universe, dark matter doesn't interact with light. So how do astronomers know it is there?
Galaxy cluster X-ray discovery scores another win for the Big Bang theory
Scientists have found that the distribution of matter in galactic clusters supports the lambda cold dark matter model of cosmology.
Bizarre object 10 million times brighter than the sun defies physics, NASA says
A bizarre 'ultraluminous X-ray source' shines millions of times brighter than the sun, breaking a physical law called the Eddington limit, a new study finds.
What are gravitational waves?
Reference Gravitational waves are tiny ripples in the fabric of time and space that are created by some of the universe's most powerful events such as colliding black holes.
Dark energy could lead to a second (and third, and fourth) Big Bang, new research suggests
Scientists have proposed a way that the universe could stop expanding, ending in a 'Big Crunch' that resets space and time as we know it.
Only filmed interview with Georges Lemaître, 'father of the Big Bang,' rediscovered after 60 years
The only known filmed interview with physicist and Catholic priest Georges Lemaître, who originally proposed the Big Bang theory, has been found on a video that was lost nearly 60 years ago.
How was the universe created?
We don't really know how the universe was created, though most astrophysicists believe it started with the Big Bang.
