Scientists Send Quantum Data Through a Simulated Wormhole
For the first time, scientists have created a quantum computing experiment for studying the dynamics of wormholes — that is,…
What is the Maximum Number of Moons that Earth Could Have?
In a recent study published in Earth and Planetary Astrophysics, a team of researchers from the University of Texas at…
Large Hadron Collider Restarts, Shooting Protons at Record Energy Levels
Europe's Large Hadron Collider has started up its proton beams again at unprecedented energy levels after going through a three-year…
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,…
Scientists Recreate the Density of a White Dwarf in the Lab
Inside a white dwarf, atoms are squeezed almost to the point of collape. Now we've created this matter in a…
Why Pulsars Are So Bright
When pulsars were first discovered in 1967, their rhythmic radio-wave pulsations were a mystery. Some thought their radio beams must…
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…
Could The Physical Constants Change? Possibly, But Probably Not
The laws of physics are rooted in universal physical constants. But what if these constants change over time?
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…
How Large Can A Planet Be?
When it comes to planets, the largest planet in the universe probably isn't the most massive.
