Dark matter might have had a turbulent youth. According to an international team, this invisible substance may have formed at ...

Observations of the thermal energy in a baby galaxy cluster 12.4 billion light years away suggest much more energetic early ...

Astronomers have stumbled onto a structure so vast and so oddly shaped that it threatens to upend one of cosmology’s most ...

Anaxagoras, a visionary Greek philosopher, foresaw concepts of expanding universe and multiple worlds centuries before modern science.

Recent observations create a puzzle for astrophysicists: since the big bang, less galaxy clusters have formed over time than was actually expected. Physicists from the university of Bonn have now ...

In my opinion, the theory of evolution by natural selection is one of the most elegant and by far one of the most encompassing theories humanity has ever come up with. Even though it was originally ...

What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open ...

Everything in the universe has gravity — and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...
