Sealed in an Envelope for a Decade, Another Surprise in the Quest to Unravel the Mystery of Gravity Emerges
A twist on gravity measurement, hidden in a mysterious envelope, may point to a subtle flaw in our…
Einstein-Rosen Bridges May Not Be Wormholes After All, Physicists Reveal
The concept of the Einstein-Rosen bridge is often understood as a cosmic shortcut, akin to a tunnel that…
The ‘age of gravitational astronomy’ is here
Just more than a decade ago, the Laser Interferometer Gravitational-Wave Observatory (LIGO) picked up the signal of something…
This strange new phase of matter could transform quantum technology
Researchers from Brown University and the University of Michigan have achieved something that scientists had only imagined until…
The Sun might look yellow, but seen from space without an atmosphere filtering its light, the sun is actually white — and the yellow color we see from Earth is the result of our atmosphere scattering blue wavelengths away, in the same physics that makes the sky appear blue
The Sun is depicted as yellow in children’s drawings, in weather icons, on flags, and in the standard…
Light takes about 8 minutes to travel from the sun to the Earth, but the energy carried in that sunlight was generated in the sun’s core tens to hundreds of thousands of years ago — bouncing through the sun’s interior for that entire time before finally escaping its surface and making the 8-minute trip across space
Sunlight takes about eight minutes and twenty seconds to travel from the Sun to the Earth. That figure…
Stanford quantum computing breakthrough uses twisted light to work without extreme cooling
Quantum computers today are notoriously difficult and expensive to operate. Most require temperatures near absolute zero, about -459…
The Force That Holds Atoms Together May Be Driving the Universe Apart
Here’s what you’ll learn when you read this story: The universe is expanding faster every second, and physicists…
Something Revealed Itself by Bending the Light of a Distant Star in 2019—Now Astronomers Are Racing to Find Out What It Was
For just an hour in late 2019, a cosmic mystery revealed itself to astronomers in an unprecedented way:…
The surface of the Sun is around 5,500 degrees, but its outer atmosphere is more than a million degrees hotter, and after decades of work physicists still cannot fully explain how the cooler layer heats the one above it.
The visible surface of the Sun, the photosphere, sits at around 5,500 degrees Celsius. Its outer atmosphere, the…
