Could Echoes from Colliding Black Holes Prove Stephen Hawking’s Greatest Prediction?

In 1974 Stephen Hawking theorized that black holes are not black but slowly emit thermal radiation. Hawking’s prediction shook physics to its core because it implied that black holes cannot last forever and that they instead, over eons, evaporate into nothingness—except, however, for one small problem: there is simply no way to see such faint … Read more

Can We Gauge Quantum Time of Flight?

Scientific American January 2022 Measuring the time it takes particles to travel between two points may be the best test yet for Bohmian mechanics A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum … Read more

James Webb Space Telescope Reaches Its Destination in Huge Mission Milestone

The James Webb Space Telescope has fired its thrusters and reached its orbital destination around a million miles (1.5 million kilometers) away from our planet, NASA said Monday, a key milestone on its mission to study cosmic history.   At around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for 5 minutes … Read more

40 quintillion stellar-mass black holes are lurking in the universe, new study finds

Scientists have estimated the number of “small” black holes in the universe. And no surprise: It’s a lot. This number might seem impossible to calculate; after all, spotting black holes is not exactly the simplest task. Because they’re are as pitch-black as the space they lurk in, the light swallowing cosmic goliaths can be detected … Read more

Physicists Detect Mysterious X Particles in ‘Primordial Soup’ For The First Time

A mysterious particle thought to have existed briefly just after the Big Bang has now been detected for the first time in the ‘primordial soup’. Specifically, in a medium called the quark-gluon plasma, generated in the Large Hadron Collider by colliding lead ions. There, amid the trillions of particles produced by these collisions, physicists managed … Read more

Expansion of the universe: Conflicting measurements are becoming a serious problem

The Hubble constant describes how fast the universe is expanding, but our measurements won’t line up, which may mean our standard model of the universe is wrong Space 20 January 2022 By Leah Crane Images taken by the Hubble Space Telescope of galaxies looked at in the study ESA The expansion of the universe is … Read more

A New Study Calculates The Number of Black Holes in The Universe. It’s a Lot

Because we can’t see black holes, it’s hard to know exactly how many are out there in the big, wide Universe. But that doesn’t mean we have no means of trying to figure it out. Stellar-mass black holes are the collapsed cores of dead massive stars, and new research incorporating how these stars and binaries … Read more

SpaceX Satellites Have Invaded Astronomers’ Views of The Sky, And It’s Getting Worse

With the rapid expansion of commercial space, there is a growing number of satellites in orbit around our planet. Most of these are in low-Earth orbit, which is becoming increasingly crowded.   This has led some to be concerned about a catastrophic rise of space debris, as well as a growing frustration by astronomers due … Read more
