Time travellers could use parallel dimensions to visit the past, scientists claim

Posted by in categories: cosmology, physics, time travel

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.

Kardashev Scale: This Is What Life Will Look Like When We Harness the Energy of the Entire Universe

Posted by in categories: energy, physics, space

In Brief:

  • A Type IV civilization is a society that has managed to harness the energy of the entire universe.
  • To get here, we would need to tap into energy sources unknown to us using strange laws of physics (laws that may or may not exist).

To measure the level of a civilization’s advancement, the Kardashev scale focuses on the amount of energy that a civilization is able to harness. Obviously, the amount of power available to a civilization is linked to how widespread the civilization is (you can’t harness the power of a star if you are confined to your home planet, and you certainly can’t harness the power of a galaxy if you can’t even get out of your solar system).
