Atomic Clocks Separated by Just a few Centimetres Measure Different Rates of Time. Just as Einstein Predicted
The connection between relativity and quantum mechanics has been a black box for the world of physics for decades. That…
What is Einstein’s Theory of Relativity?
More than a century after he first proposed it, Einstein's Theory of Relativity is still foundational to our understanding of…
Gravitational Waves Could Explain why There’s More Matter Than Antimatter in the Universe
One of the questions underpinning both philosophy and science is “why are we here”? Ask an astrophysicist, and they might…
Even the Quiet Supermassive Black Holes are Blasting out Neutrinos and Gamma Rays
Is there anywhere in the Universe where we can escape from radiation? Certainly not here on Earth. And not in…
Matter From Light. Physicists Create Matter and Antimatter by Colliding Just Photons.
An effect predicted in 1934 has finally been observed, creating matter from light alone.
Don’t Be Surprised if EmDrive Experiments Never Work
Every few years the "EmDrive", a proposed method of generating rocket thrust without any exhaust, hits the news. Each time,…
Sending a Spacecraft to Another Star Will Require a Million Lasers Working Together
New research from the Australia National University shows that millions of lasers are the way to propel Breakthrough Starshot on…
Fermilab’s Muon g-2 Experiment Finally Gives Particle Physicists a Hint of What Lies Beyond the Standard Model
The results of the first run of the Muon g-2 experiment at Fermilab indicate that there could be physics beyond…
There Could be Magnetic Monopoles Trapped in the Earth's Magnetosphere
If magnetic monopoles exist, they might be found in Earth's magnetic field. A new paper gives the first results of…
Wormholes Could Allow Travel Across the Universe, as Long as Your Spacecraft is Microscopic
An alternative to general relativity predicts wormhole travel is possible, but only if you're teeny-tiny.
