"In this way, the amount of dark matter that we measure in the universe today is a direct result of this filtration in the first fractions of a second after the Big Bang."

New theory: Dark matter was created by "boiling" bubbles of plasma

Origin Story

Scientists have a new idea for where dark matter came from: "boiling" bubbles of plasma at the beginning of the universe.

Scientists: That "99.9% dark matter" galaxy is actually perfectly normal

Propagation Of Error

The galaxy Dragonfly 44, which scientists said had a baffling 10,000-to-one ratio of dark matter to visible matter, may not be so unique after all.

Scientists: That “99.9% Dark Matter” Galaxy Is Actually Perfectly Normal

"Our work shows that this galaxy is not so singular nor unexpected."

We may know less about dark matter than we thought.

Dark matter's effect is 10x what it should be, scientists say

Dark Matter Mystery

According to new research, dark matter may be an even bigger mystery than we initially thought. The theoretical maps aren't lining up with observations.

If you ask physicist Sabine Hossenfelder, building bigger particle colliders is a waste of money and effort.

Physicist pleads: Stop building stupid particle colliders

Impulse Buy

CERN wants a bigger, better particle collider. But with no guarantee for breakthrough discoveries, physicist Sabine Hossenfelder says don't bother.

Physicist Pleads: Stop Building Stupid, Expensive Particle Colliders

Building huge new colliders is a terrible waste of money, a prominent physicist says.

"If this is real, calling it a game changer would be an understatement."

Physicists may have just discovered something revolutionary

I Must Axion A Question

An international team of physicists claim they may have found evidence for a new type of subatomic particle called the axion.

Physicists Say They’ve Found Evidence of Elusive Axion Particle

These findings may have just opened the door to a new era in physics.

"Maybe there is a final theory of physics, or maybe it is approximations all the way down."

The guy who invented dark matter has some doubts

Revisiting Ideas

Jim Peebles, who first theorized about dark matter, argues in a new essay that there's still a lot of work to be done in proving his ideas.

The Guy Who Invented Dark Matter Has Some Doubts

"We haven’t been issued a guarantee that we can make sense of the physical world around us."

It threatens a popular hypothesis for what dark matter is made of, but many in the research field aren't convinced.

Shocking research threatens our understanding of dark matter

Controversial Discovery

A research team failed to find a widely-accepted dark matter particle candidate in the Milky Way galaxy, causing a stir among disagreeing astrophysicists.

Shocking Research Threatens Our Understanding of Dark Matter

Either scientists were wrong about dark matter, our galaxy doesn't have any, or the paper is wrong.

Scientists thought the case of the cosmic rays' source was closed, but new evidence cracks it wide open again.

MIT: Dark matter at our galaxy's core may be blasting gamma rays

Ongoing Debate

Scientists thought they ruled out dark matter as the source of bizarre cosmic gamma rays coming from the core of the Milky Way. New evidence disagrees.
