Scientists Found a Low-Cost Way to Produce the World’s Cleanest Energy Source

Posted by in categories: energy, physics

Scientists have discovered a low-cost, efficient catalyst for splitting water to create hydrogen. This means that the world’s cleanest form of energy, hydrogen, may be more easily and cheaply produced.

Physicists at the University of Houston have discovered a low-cost, efficient, and easily available catalyst that can split water into hydrogen and oxygen. The catalyst is far more efficient than other options that have previously been employed, and because it is grown from ferrous metaphosphate on a conductive nickel foam platform, it is both more durable and cheaper to produce.

For The First Time, Physicists Have Observed a Giant Magnetic ‘Bridge’ Between Galaxies

Posted by in categories: physics, space

For the first time, scientists have detected evidence of a magnetic field that’s associated with the vast intergalactic ‘bridge’ that links our two nearest galactic neighbours.

Known as the Magellanic Bridge, the bridge is a huge stream of neutral gas that stretches some 75,000 light-years between our two neighbouring galaxies, the Large and Small Magellanic Clouds (LMC and SMC). Although researchers had predicted it was there, this is the first observation of its magnetic field, and it could help us understand how these vast bridges come to be.

“There were hints that this magnetic field might exist, but no one had observed it until now,” said lead researcher, Jane Kaczmarek from the University of Sydney.

NASA’S STUNNING BREAKTHROUGH: It’s First Warp Drive…Is a TRUE Mindblower!

Posted by in categories: information science, physics, space travel

A few months ago, physicist Harold White shocked the aeronautics industry when he announced that his team at NASA was in the process of developing a faster-than-light warp drive. His design could one day transport a spacecraft to the nearest star in a matter of weeks.

The idea originally came to White while he was considering an equation formulated by physicist Miguel Alcubierre in his 1994 paper titled, “The Warp Drive: Hyper-Fast Travel Within General Relativity. Alcubierre suggested a mechanism by which space-time could be “warped” and behind a spacecraft.

Michio Kaku dubbed Alcubierre’s theory a “passport to the universe,” which harnesses a quirk in the “cosmological code” that allows for the expansion and contraction of space-time. If proven true, it could allow for hyper-fast travel between interstellar destinations. In order to accomplish this, the starship would need able to expand the space behind it rapidly to push it forward. For passengers, it would look like a lack of acceleration.

Scientists are waging a war against human aging. But what happens next?

Aubrey de Grey in this new interview with Vox.


We all grow old. We all die.

For Aubrey de Grey, a biogerontologist and chief science officer of the SENS Research Foundation, accepting these truths is, well, not good enough. He decided in his late twenties (he’s currently 54) that he “wanted to make a difference to humanity” and that battling age was the best way to do it. His life’s work is now a struggle against physics and biology, the twin collaborators in bodily decay.

Physicists Just Came Up With a Mathematical Model for a Viable Time Machine

Posted by in categories: mathematics, physics, time travel

Physicists have come up with what they claim is a mathematical model of a theoretical “time machine” — a box that can move backwards and forwards through time and space.

The trick, they say, is to use the curvature of space-time in the Universe to bend time into a circle for hypothetical passengers sitting in the box, and that circle allows them to skip into the future and the past.

“People think of time travel as something as fiction. And we tend to think it’s not possible because we don’t actually do it,” says theoretical physicist and mathematician, Ben Tippett, from the University of British Columbia in Canada.

Washington State University (WSU) physicists have created a fluid with “negative mass,” which means that if you push it, it accelerates toward you instead of away, in apparent violation of Newton’s laws.

A naked singularity: Can we spot the most extreme object in the universe?

Posted by in categories: cosmology, physics, singularity

A team of scientists at the Tata Institute of Fundamental Research (TIFR), Mumbai, India, have found new ways to detect a bare or naked singularity, the most extreme object in the universe.

When the fuel of a very massive star is spent, it collapses due to its own gravitational pull and eventually becomes a very small region of arbitrarily high matter density, that is a ‘Singularity’, where the usual laws of physics may breakdown. If this singularity is hidden within an event horizon, which is an invisible closed surface from which nothing, not even light, can escape, then we call this object a black hole.

In such a case, we cannot see the singularity and we do not need to bother about its effects. But what if the event horizon does not form? In fact, Einstein’s theory of general relativity does predict such a possibility when massive stars collapse at the end of their life-cycles. In this case, we are left with the tantalizing option of observing a naked singularity.

Physicists create mind-bending ‘negative mass’ that accelerates backwards and could help explain black holes

Posted by in categories: cosmology, physics

Scientists have created a fluid with “negative mass” which they claim can be used to explore some of the more challenging concepts of the cosmos.

Washington State University physicists explained that this mass, unlike every physical object in the world we know, accelerates backwards when pushed.

The phenomenon, which is rarely created in laboratory conditions, shows a less intuitive side of Newton’s Second Law of Motion, in which a force is equal to the mass of an object times its acceleration (F=ma).

‘Negative mass’ created for the first time

Posted by in category: physics

Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It accelerates backwards. The phenomenon is rarely created in laboratory conditions and can be used to explore some of the more challenging concepts of the cosmos, said Michael Forbes, a WSU assistant professor of physics and astronomy and an affiliate assistant professor at the University of Washington. The research appears today in the journal Physical Review Letters, where it is featured as an “Editor’s Suggestion.” Hypothetically, matter can have negative mass in the same sense that an electric charge can be either negative or positive.
