Why a New Idea to Search for Extra Dimensions in the Pulse of Spacetime Is Turning Heads

Posted by in category: physics

If physicists do find that gravitational waves have travelled through dimensions other than the four we live in, it will be the start of a revolution in physics. But how close are we really?

Physicists Just Discovered an Entirely New Type of Superconductivity

Posted by in categories: materials, physics

One of the ultimate goals of modern physics is to unlock the power of superconductivity, where electricity flows with zero resistance at room temperature.

Progress has been slow, but physicists have just made an unexpected breakthrough. They’ve discovered a superconductor that works in a way no one’s ever seen before — and it opens the door to a whole world of possibilities not considered until now.

In other words, they’ve identified a brand new type of superconductivity.

How Scientists Listen to Black Holes Colliding A Billion Years Ago

Posted by in categories: cosmology, physics

Scientists at LIGO detected billion-year-old gravitational waves, and they are expecting to detect a lot more. This is an excerpt from ‘The Little Book of Black Holes’ by Frans Pretorius and Steven S. Gubser, reprinted with permission from the publisher Princeton University Press.

The Most Precise Measurement of Antimatter Yet Deepens the Mystery of Why We Exist

Posted by in categories: cosmology, physics

Scientists have made the most precise measurement of antimatter yet, and the results only deepen the mystery of why life, the universe, and everything in it exists.

The new measurements show that, to an incredibly high degree of precision, antimatter and matter behave identically.

Yet those new measurements can’t answer one of the biggest questions in physics: Why, if equal parts matter and antimatter were formed during the Big Bang, is our universe today made up of matter?

Mach Effect Propellantless drive awarded NASA NIAC phase 2 study

Posted by in categories: cosmology, physics, space travel

James Woodward and the Space Studies Institute has a Phase 2 NASA Innovative Advanced funded study. They are looking at the implementation of an innovative thrust producing technology for use in NASA missions involving in space main propulsion.

Mach Effect Gravity Assist (MEGA) drive propulsion is based on peer-reviewed, technically credible physics. Mach effects are transient variations in the rest masses of objects that simultaneously experience accelerations and internal energy changes. They are predicted by standard physics where Mach’s principle applies as discussed in peer-reviewed papers spanning 20 years and a recent book, Making Starships and Stargates: the Science of Interstellar Transport and Absurdly Benign Wormholes published in 2013 by Springer-Verlag.

Research enhances performance of Germany’s new fusion device

Posted by in categories: nuclear energy, physics

A team of U.S. and German scientists has used a system of large magnetic “trim” coils designed and delivered by the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) to achieve high performance in the latest round of experiments on the Wendelstein 7-X (W7-X) stellarator. The German machine, the world’s largest and most advanced stellarator, is being used to explore the scientific basis for fusion energy and test the suitability of the stellarator design for future fusion power plants. Such plants would use fusion reactions such as those that power the sun to create an unlimited energy source on Earth.

The new experiments amply demonstrated the ability of the five copper trim coils and their sophisticated control system, whose operation is led on-site by PPPL physicist Samuel Lazerson, to improve the overall performance of the W7-X. “What’s exciting about this is that the trim coils and Sam’s leadership are producing scientific understanding that will help to optimize future stellarators,” said PPPL physicist Hutch Neilson, who oversees the laboratory’s collaboration on the W7-X with the Max Planck Institute of Plasma Physics, which built the machine and now hosts the international team investigating the behavior of plasmas confined in its unique magnetic configuration.

Stellarators are twisty, doughnut-shaped facilities whose configuration contrasts with the smoothly doughnut-shaped facilities called tokamaks that are more widely used. A major advantage of stellarators is their ability to operate continuously with low input power to sustain the plasma without plasma disruptions—a risk that tokamaks face—enabling the facilities to operate efficiently in steady state. A disadvantage is that the twisting geometry is more complex to design and build.

33 Angry Physicists Came Together to Shut Down One Theory About the Universe

Posted by in categories: physics, space

Scientists are no strangers to healthy debate. You need criticism to strengthen your ideas, and when debate is done right, both parties leave knowing more than they did when they started. But there are some things that will just make a scientist mad. One of those things? Saying their scientific theory isn’t scientific. That’s what a trio of physicists did in a 2017 article they published in Scientific American, which stated that the idea of an expanding universe simply isn’t testable. The response from other physicists? Oh, it’s on.
