Japanese Dark Matter Detector is Seeing a “Surprising Excess of Events”
A search for dark matter has found an extra signal in their data that could point toward proof of dark…
Spacecraft was able to measure how long neutrons last before they decay
Using NASA's MESSENGER spacecraft's close encounters with Venus and Mercury, researchers were able to measure the lifetime of neutrons, an…
Time Travel Into The Future Is Totally Possible
Believe it or not, time travel is possible. In fact, you're doing it right now. Every single second of every…
Can wormholes act like time machines?
Time travel into the past is a tricky thing. We know of no single law of physics that absolutely forbids…
Gravity is tested down to a scale smaller than the thickness of a human hair
Gravity was the first force of nature to be realized, and in the centuries since we first cracked the code…
The three-body problem shows us why we can’t accurately calculate the past
Our universe is driven by cause and effect. What happens now leads directly to what happens later. Because of this,…
This is Foam, Made in Space
Say hello to Space Foam. The ESA has a science lab on the International Space Station called Columbus. Inside that…
Neutrinos Have Been Detected With Such High Energy That The Standard Model Can’t Explain Them
Although neutrinos are mysterious particles, they are remarkably common. Billions of neutrinos pass through your body every second. But neutrinos…
Just How Feasible is a Warp Drive?
At a presentation at this year's AIAA Propulsion and Energy Forum, engineer Joseph Agnew spoke of the progress being made…
Physicists Don’t Know the Mass of a Neutrino, But Now They Know it’s No Larger Than 1 Electron Volt
The Standard Model of Particle Physics is one of science's most impressive feats. It's a rigorous, precise effort to understand…
