The scientific mysteries that led to Einstein’s E=mc^2 equation

Scientists deal with mysteries. As Richard Feynman once commented:  “Science must remain a continual dialog between skeptical inquiry and a sense of inexplicable mystery”.Three examples: it is profoundly mysterious as to why mathematics can so accurately describe our physical world, and even predict events, such as the motion of the planets or the propagation of radio waves from earth to spacecraft.  The theorems of mathematics are not normally thought to derive from properties of the real world...

3 scientists school flat Earthers on the evidence

Despite centuries of evidence proving otherwise, there are an alarming number of people around the world who genuinely believe that the earth is flat. Bill Nye The Science Guy, NASA astronomer Michelle Thaller, and Neil deGrasse Tyson strongly disagree.From simple experiments like standing at a seashore or looking through a telescope at other planets, to reading about navigation or viewing photos of Earth taken from space, the scientists share several ways that flat Earthers can see the truth fo...

Experiment proves old theory how aliens might use black holes

Scientists prove a 50-year-old physics theory by Roger Penrose.The theory explains how energy could be harvested from black holes by advanced aliens.Researchers from the University of Glasgow twisted sound waves to show that the effect Penrose described is real. A theory proposed 50 years ago to explain how energy might be harvested from a black hole was verified by an experiment. Scientists from the University of Glasgow were able to provide first proof for an idea from 1969 by the famed Briti...

Why we can stop worrying and love the particle accelerator

What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter. Particle accelerators allow physicists to study subatomic particles by speeding them up in powerful magnetic fields and then tracing the interactions that result from collisions. By delving into the mysteries of the Universe, colliders hav...

Understanding quantum mechanics [quiz]

Mechanics is that part of physics concerned with stuff that moves, from cannonballs to tennis balls, cars, rockets, and planets. Quantum mechanics is that part of physics which describes the motions of objects at molecular, atomic, and sub-atomic levels, such as photons and electrons.Although quantum mechanics is an extraordinarily successful scientific theory, on which much of today’s tech-obsessed lifestyles depend, it is also completely mad. The theory quite obviously works, but it appears to...

Cern poised to back plan for €20bn successor to Large Hadron Collider

Proposed 100km circular tunnel would be four times as big and six times as powerful as LHCAs the largest scientific instrument on the planet enters its twilight years, Cern scientists have been facing the question of what next after the Large Hadron Collider (LHC). Following extensive debate, they appear to have landed on an answer: go bigger or go home.Cern’s council is expected to announce its backing on Friday for a proposed new collider with a 100km circular tunnel, four times the size and s...

How does gravity bend spacetime?

We typically think of events as happening in space and in time. "In reality, space and time are strongly intertwined things and the union of them is called spacetime," explains Konstantin Batygin. The force that we understand as gravity, according to Batygin, is the result of the spacetime continuum being curved by Earth's gravitational field. Depending on how close you are to the source of gravity, time will pass at different rates.Traveling backward in time is not possible. Traveling forward t...

Scientists generate electricity from shadows

In most approaches to convert light into electricity, shadows are a bummer. Now though, researchers from the National University of Singapore (NUS) devised a shadow-effect energy generator (SEG) that scavenges electricity from the contrast between light and shadow. “When the whole SEG cell is under illumination or in shadow, the amount of electricity generated is very low or none at all. When a part of the SEG cell is illuminated, a significant electrical output is detected. We also found ...

3 mind-blowing space facts with Neil deGrasse Tyson

Astrophysicist Neil deGrasse Tyson joins us to talk about one of our favorite subjects: space. In the three-chaptered video, Tyson speaks about the search for alien life inside and outside of the Goldilocks Zone, why the term "dark matter" should really be called "dark gravity," and how the rotation of the Earth may have been the deciding factor in a football game.These fascinating space facts, as well as others shared in Tyson's books, make it easier for everyone to grasp complex ideas that are...

Mystery anomaly weakens Earth's magnetic field, report scientists

"The South Atlantic Anomaly" in the Earth's magnetic field is growing and possibly splitting, shows data.The information was gathered by the ESA's Swarm Constellation mission satellites.The changes may indicate the coming reversal of the North and South Poles. A portion of the Earth's magnetic field, known as the "South Atlantic Anomaly," is weakening and may be headed for a split, shows new data. The strange phenomenon is also triggering technical problems in Earth-orbiting satellites. Our pla...

With $84 million in new cash, Commonwealth Fusion is on track for a demonstration fusion reactor by 2025

Commonwealth Fusion Systems closed on its latest $84 million in new funding two weeks ago. The U.S. was still very much in the lockdown phase and getting a deal done, especially a multi-million dollar investment in a new technology aiming to make commercial nuclear fusion a reality after decades of hype, was “an interesting thing” in the words of Commonwealth’s chief executive, Bob Mumgaard.  It was actually one time when the technical complexity of what Commonwealth Fusion is trying to achie...

The mystery of moving, mossy, ‘glacier mice’

Weird but cute, "glacier mice" are actually balls of moss, dirt, and more.The balls move, oddly, in packs through some unknown means.A new study tracked 30 glacier mice but still couldn't figure out what's going on. Scientists have known about them at least since the 1950s, when Jón Eythórsson named them "jökla-mýs," which translates as "glacier mice." However, they're not actually mice. They're smallish balls of moss, and there are lots of them atop Alaska's Root Glacier. They can also be foun...

Of course, there might be numerous reasons we have not encountered aliens yet, from having poor technology to the alie...

Ask an Astronaut: What surprised you most in space?

Astronaut Garrett Reisman took in countless indescribably beautiful views while he lived in space. But most shocking, he says, was observing the thinness of Earth's atmosphere.You can compare the thickness of the atmosphere to the diameter of Earth to the skin on an apple, or the shell of an egg. It's incredibly thin and shows just how seemingly fragile our planet is.But to put this into perspective, whereas the atmosphere reaches a height of 300,000 feet from Earth's surface, the deepest part o...
