For decades, astrophysicists have wrestled with a basic but brutal question: how did black holes in the early Universe grow ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

Scientists studying dark matter have published new findings based on a warped extra dimension model that suggests particles ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Space is filled with a variety of objects, some blisteringly hot, some tremendously cold, but areas with little to nothing at all never drop to absolute zero thanks to a fossil relic left over from ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a ...

A former Harvard physics professor argues that established cosmological theory places Heaven beyond the observable universe, ...

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics. New ...

Delve into the detail of atomic physics. As the basic units of matter, atoms are the building blocks for everything in the universe. Once thought to be indivisible, we now know they can indeed be ...
