Philosophy
Examine life’s biggest questions, from ethics to existence, with curiosity and critical thinking.
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
The matter that creates black holes won't be what comes out when they evaporate. Will the black hole information paradox ever be solved?
In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
In technology, we make cumulative advances that withstand time. Not so in politics and ethics, argues philosopher John Gray.
We experience time as real. But what if it's only an illusion: an illusion that's inherently relative? Does time fundamentally even exist?
Generations ago, cosmologists asserted that the Universe might not just be the same in all directions, but at all times. But is that true?
When the road runs out, you've got to make your own way.
We live in a four-dimensional Universe, where matter and energy curve the fabric of spacetime. But time sure is different from space!
The double-slit experiment, hundreds of years after it was first performed, still holds the key mystery at the heart of quantum physics.
Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn't instant.

Our ability to build machine intelligence has outrun our ability to understand it. Professor Alan Love, director of the Minnesota Center for Philosophy of Science, thinks biology can help close that gap.
The artistic and the mathematical mind are not so far apart.
As far as we can tell, there's no limit to how far it goes on; only a limit to how far we can see. Could the Universe truly be infinite?

We’ve been asking whether we have a purpose. Philosopher Alan Love says the better question is: what kind of purpose can we identify, document, and explain?
Books to expand your perspective on history, philosophy, space exploration, and more this year.
Our Universe has a positive, non-zero value to the energy within empty space. Can we potentially save ourselves by considering vacuum decay?
The philosopher Svetlana Boym argues that "nostos" encourages people to reject the world as it is and seek to return to a better time — real or imagined.
People are almost always different to how we imagine them
