Shining a Light on Dark Matter Halos

Since the 1970’s dark matter and all that comes with it has remained a mystery for scientists. We know it’s there, but proving it has always been …

Big Bang Confirmed Again, This Time By The Universe's First Atoms

The Big Bang is the leading theory as to where our Universe came from. The Universe was hotter, denser, more uniform, and smaller in the past, and is only as vast as it is today due to the fabric of expanding space. This idea was extremely controversial for many decades, until detailed observations …

Mystery of the universe's Cold Spot deepens – it's not a supervoid

A huge cold region of the universe spanning billions of light years is not a blank patch mostly empty of galaxies, astrophysicists have …

Ask Ethan: How many black holes are there in the Universe?

You know what a black hole is, and we’ve found a few so far. But oh, are there ever so many more out there!<p><i>“Black holes are the seductive dragons of</i> …

Scientists Propose a New Planetary Object That Could Change Everything

A new type of planetary object has been proposed this month which scientists are calling a synestia. While this doughnut-shaped object may have been …

Wave twice the size of the Milky Way found sweeping through the Perseus cluster

Scientists believe they've spotted the biggest wave ever discovered. But before you pull out your surfboard, you should probably know this is a tad …

Scientists Uncover The First Ever Evidence of The Multiverse

For years, scientists have been baffled by a weird anomaly far away in space: a mysterious “Cold Spot” about 1.8 billion light-years across. It is …

In A First, Gravitational Lens Reveals Magnified And Multiplied Images Of A Type 1a Supernova

Astronomers have, for the first time, detected a gravitationally lensed type 1a supernova — objects that always explode with the same brightness, and …

Remembering the first 'photo' of a black hole

Black holes are so outlandish that the scientists who first thought them up figured they couldn't possibly exist in reality. They form from massive, collapsed stars and are so dense that nothing can escape their gravitational pull, including light. Black holes mess with spacetime so badly that …

Filaments Of Dark Matter Are Seen Between Galaxies

Dark matter is difficult to study. Since it doesn’t interact with light, it is basically invisible. But it does have mass, and that means it deflects light ever so slightly, an effect known as weak gravitational lensing. By observing the way light from distant galaxies is distorted, we can map the …

Ask Ethan: What Was The Entropy Of The Universe At The Big Bang?

The second law of thermodynamics is one of those puzzling laws of nature that simply emerges from the fundamental rules. It says that entropy, a measure of disorder in the Universe, must always increase in any closed system. But how is it possible that our Universe today, which looks to be …

A gigantic ring of galaxies could force physicists to rethink gravity as we know it

Scientists have discovered that a gigantic ring of galaxies stretching 10 million light-years wide is speeding away from our own galaxy so fast, our current physics models can't explain it.<p>Describing the structure as expanding rapidly like a "mini Big Bang", the team thinks it was formed by a …

Does Dark Matter Exist, Or Is Gravity Wrong? The Answer Lies Billions Of Years In The Past

When we look out at the luminous matter in the Universe — stars, galaxies, clusters of galaxies and the hot gas in and between them — it tells a couple of different stories. One is the story of how normal matter (based on atomic nuclei and electrons) comes together to emit, absorb and otherwise …

Recent Claims Invalid: Emergent Gravity Might Deliver A Universe Without Dark Matter

Gravity is one of the four fundamental forces of nature, which means it’s not derived from anything else – it just is. At least, that’s according to our presently accepted theories. But this may be about to change.<p>Physicists today describe the gravitational interaction through Einstein’s Theory of …
