Space Warp Dynamics: The startup that’s working on sending humans to Proxima Centauri

Posted by in categories: physics, science, space, space travel
Space Warp Dynamics’s mission is fundamentally an audacious endeavor in terms of what we deem as the status quo of spacecraft propulsion and in terms of where humanity will be able to reach in the galaxy (other stars) within the next 15–20 years (and not only within the next 200+ years from now). In other words, if this challenge can be addressed with the appropriate resources and the right people’s support, then for example you and your family will potentially be able to travel to Earth 2.0 (presumably in the Proxima Centauri star system).
Space Warp Dynamics can already currently demonstrate (prove) that their invention can manipulate (warp or bend) space-time in a controlled micro-environment. This could mean that we finally know how gravity works and also how to control gravity and this in itself is a monumental accomplishment.

Scientists to Challenge Albert Einstein’s ‘Speed of Light is Constant’ Theory

Posted by in category: physics

A team of scientists from London and Canada is set to challenge one of Albert Einstein’s accepted theories regarding the classification of the speed of light as constant, which means that light in a vacuum will have the same numerical value under any conditions.

The new theory of the scientists, described in a paper published in the journal Physical Review, hypothesizes that the speed of light might actually be a variable.

THERE are multiple timelines playing out in parallel universes, according to a team of researchers.

The sensational claim was made by a team of physicists, who believe that the parallel universes can all affect one another.

‘Diamond-age’ of power generation as nuclear batteries developed

Posted by in categories: nuclear energy, physics

New technology has been developed that uses nuclear waste to generate electricity in a nuclear-powered battery. A team of physicists and chemists from the University of Bristol have grown a man-made diamond that, when placed in a radioactive field, is able to generate a small electrical current.

Gravity may have chased light in the early universe

Posted by in categories: physics, space

By Michael Brooks

It’s supposed to be the most fundamental constant in physics, but the speed of light may not always have been the same. This twist on a controversial idea could overturn our standard cosmological wisdom.

In 1998, Joao Magueijo at Imperial College London, proposed that the speed of light might vary, to solve what cosmologists call the horizon problem. This says that the universe reached a uniform temperature long before heat-carrying photons, which travel at the speed of light, had time to reach all corners of the universe.

Physicists Just Discovered a Second State of Liquid Water

Posted by in category: physics

It’s one of the most fundamental compounds on Earth, and it makes up roughly 60 percent of the human body, and yet water is turning out to be stranger than we could have ever imagined.

Researchers have been investigating the physical properties of water, and found that when it’s heated to between 40 and 60 degrees Celsius, it hits a ‘crossover temperature’, and appears to start switching between two different states of liquid.

As a chemical compound, water is so vital to life on Earth, we’ve been underestimating how legitimately weird it is.

Synthetic biology research may enable future capabilities for Soldiers

Posted by in categories: bioengineering, biotech/medical, computing, military, physics

ADELPHI, Md. — A U.S. Army Research Laboratory biotechnology scientist recently published an editorial article on the future directions of synthetic biology research to meet critical Army needs in the Synthetic Biology edition of the Journal of the American Chemical Society.

In the publication, Dr. Bryn Adams, who works in ARL’s Bio-Technology Branch, highlights examples of robust, tractable bacterial species that can meet the demands of tomorrow’s state-of-the-art in synthetic biology.

“ACS Synthetic Biology is the premier synthetic biology journal in the world, with a wide readership of biologists, chemists, physicists, engineers and computer programmers,” Adams said. “A publication in this journal allows me to challenge the leaders in the field to meet a Department of Defense specific need — the need for new synthetic biology chassis organisms, or host cell, and toolkits to build complex circuits in them.”

IF solid metallic hydrogen is a really good room temperature superconductor

Posted by in categories: materials, physics

On October 5th 2016, Ranga Dias and Isaac F. Silvera of Lyman Laboratory of Physics, Harvard University released the first experimental evidence that solid metallic hydrogen has been synthesized in the laboratory.

It took 495 GPa pressure to create. The sample is being held in the cryostat in liquid nitrogen.

If as predicted by theory the metallic hydrogen remains metastable when the extreme pressure is removed then the world will eventually be greatly changed.
