This logarithmic view of the Universe will blow your mind
From here to the limits of what we can see, here's a breathtaking illustrated logarithmic view of the Universe.
What are wormholes? An astrophysicist explains
A wormhole is like a tunnel between two distant points in our universe that cuts the travel time from one point to the other.
The true meaning of Einstein’s most famous equation: E=mc²
Although most people can name Einstein's most famous equation, E = mc², very few people can explain what it means.
There are more galaxies in the Universe than even Carl Sagan ever imagined
There are between 6 and 20 trillion galaxies out there. Carl Sagan's "billions and billions" was far too low of a guess.
The Universe is flat. Here’s what that teaches us.
When we measure it, we find that our Universe really is flat. Here's what we can learn from that, and why it matters so much.
A new nova disappeared faster than ever, and an even bigger cosmic catastrophe is coming
Today, the fastest-ever nova to fall off has been discovered, and even faster ones may be out there. What comes next?
NASA-funded scientist says “MEGA drive” could enable interstellar travel
The mega drive might provide enough thrust for a spacecraft to travel near the speed of light using only electricity, says one physicist.
Black hole mergers obey the laws of thermodynamics
An analysis of the gravitational wave data from black hole mergers show that the event horizon area, and entropy, always increases.
Why Einstein is a “peerless genius” and Hawking is an “ordinary genius”
Why some people are considered geniuses while other equally impressive people are not seems largely arbitrary.
Scientists see “rarest event ever recorded” in search for dark matter
Researchers observed an ultra-rare particle interaction that reveals the half-life of a xenon-124 atom to be 18 sextillion years.
quantum simulator
Australian scientists put the quantum world on a microchip
A first-of-its-kind quantum simulator could lead to the creation of never-before-seen materials powered by quantum phenomena.
Nuclear isomers were discovered 100 years ago
Protons and neutrons in an atom’s nucleus can be arranged in different configurations, creating nuclear isomers.
Lasers could cut lifespan of nuclear waste from “a million years to 30 minutes,” says Nobel laureate
If no solution is found, we're already stuck with some 22,000 cubic meters of long-lasting hazardous waste.
After 350 years, astronomers still can’t explain the solar system’s strangest moon
Saturn's Iapetus, discovered way back in 1671, has three bizarre features that science still can't fully explain.
Einstein was right. Flying clocks around the world in opposite directions proved it.
By flying planes both with and against Earth's rotation, and returning them all to the same starting point, we tested Einstein's theory.
How the Kessler Syndrome can end all space exploration and destroy modern life
The sheer amount of stuff already floating in space makes the domino effect of explosions a likely possibility.
Search reveals eight new sources of black hole echoes
The researchers' findings will help scientists trace a black hole’s evolution as it feeds on stellar material.
Scientists blow up their lab after creating strongest magnet ever
Scientists knew that it would probably explode, but they did not expect to reach such a record magnetic field.
LHC
The Large Hadron Collider is back online
The world's biggest particle accelerator, the Large Hadron Collider (LHC), is back online after a three-year hiatus.
gravitational waves
Gravitational waves could be “pushing” the Moon
A new study suggests we use the orbit of the Moon to find gravitational waves we can’t currently detect in other ways.
Nuclear fusion hit a milestone thanks to better reactor walls
A team of scientists have shattered the record for the amount of energy produced during a controlled, sustained fusion reaction.
In a hole in Earth’s magnetic field, neuroscientists are peering into the human brain
By using quantum physics to measure magnetic fields, researchers are pushing closer to measuring the brain in ways we couldn't before.
Nuclear power plant in Belgium.
Nuclear fusion: how excited should we be?
We know that fusion works – it is the process that powers the Sun, providing heat and light to the Earth. But can we do it ourselves?
Artist’s impression of the AT2018cow
Record-breaking supernova manages to “X-ray” the entire Universe
“When I saw the data, I didn’t believe the analysis...This is the brightest Cow supernova seen to date."
We now know the big bang theory is (probably) not how the universe began
Scientists used to think the universe began from a singularity. Nearly 100 years later, we're not so sure.
Scientists observed what Einstein predicted a century ago
Physicists claim to have generated matter from pure light particles for the first time — a spectacular display of Einstein's most famous equation.
supermassive black hole
Light from behind supermassive black hole detected for first time
The first direct observation of light from behind a supermassive black hole confirms a prediction in Einstein’s theory of general relativity.
balloon-borne telescope
NASA’s new balloon-borne telescope is ready for liftoff
NASA’s new balloon-borne telescope could let astronomers study distant objects with the latest tech at a fraction of the cost of Hubble.
