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

When the 49ers lost in the playoffs, some fans embraced a theory about electromagnetic waves instead of facing reality.

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

At 3.3 billion light-years across, the ring may challenge the “cosmological principle” that the universe looks uniform at sufficiently large scales.

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of ...

Particles faster than light could revolutionise our understanding of space, time, and the universe’s fundamental laws.

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 ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

Hints of impossibly bright, massive objects in the infant universe have forced astronomers to rethink how the first cosmic ...

What if there are other universes, just like ours? With an infinite number of Earths? With uncountable versions of you? And what if we don’t have to look too far to find them? Maybe a mirror version ...
