The concept or idea of a multiverse fascinates physicists’ as much as sci-fi fans, but if science was able to prove it exists, could every type of universe within it actually be predicted? The late Stephen Hawking believed there was a way to shed light on this strangest cosmic mystery.

Hawking’s final paper, published in the journal High-Energy Physics revisits one of his earlier (and no less mind-blowing) theories. The “no-boundary proposal” considers Einstein’s suggestion that the pre-Big Bang universe was a singularity, an extremely dense and hot micro-speck of matter where the laws of physics didn’t apply. Hawking speculated that time as we know it was nonexistent in this singularity, which had no beginning and no end—infinite and spherical rather than finite and linear. The embryonic universe is thought to have expanded rapidly and spawned parallel worlds during a period known as cosmic inflation.

According to a University of Portsmouth study, a new physics law could allow for the early prediction of genetic mutations.

The study discovers that the second law of information dynamics, or “infodynamics,” behaves differently from the second law of thermodynamics. This finding might have major implications for how genomic research, evolutionary biology, computing, big data, physics, and cosmology develop in the future.

Lead author Dr. Melvin Vopson is from the University’s School of Mathematics and Physics. He states “In physics, there are laws that govern everything that happens in the universe, for example how objects move, how energy flows, and so on. Everything is based on the laws of physics. One of the most powerful laws is the second law of thermodynamics, which establishes that entropy – a measure of disorder in an isolated system – can only increase or stay the same, but it will never decrease.”

Perhaps one of the most common technologies seen in science fiction is anti-gravity and gravity manipulation. Today we’ll examine if there’s an scientific pathways in physics to permit such technology, and what sort of amazing options it might offer if developed in the future.

Today we’ll talk about one of my favorite topics, warp drives. I am fascinated by warp drives because they are future technology straight out of science fiction and yet they are not for any obvious reason impossible. After all, Einstein taught us that space can indeed deform and that distances can indeed shrink and that time can indeed dilate. So why not bend and deform space-time to get us faster from one place to another?

Well, the devil is in the details. While warp drives have been studied in Einstein’s theory of general relativity, they require unphysical stuff: negative energies, repulsive gravity, or things that move faster than light already. In this video, I summarize what new scientific literature has been published on this in the past year, and what progress has been made.

Einstein’s theory of general relativity has made countless correct predictions and yet physicists are constantly trying to prove it wrong. Why? What would it be good for to prove Einstein wrong? And how could it be done? In this video I go through the most promising experiments that physicists currently work on which could prove Einstein wrong.

Everything we do as living organisms is dependent, in some capacity, on time. The concept is so complex that scientists still argue whether it exists or if it is an illusion.

In this video, astrophysicist Michelle Thaller, science educator Bill Nye, author James Gleick, and neuroscientist Dean Buonomano discuss how the human brain perceives of the passage of time, the idea in theoretical physics of time as a fourth dimension, and the theory that space and time are interwoven.

Thaller illustrates Einstein’s theory of relativity, Buonomano outlines eternalism, and all the experts touch on issues of perception, definition, and experience.

The physics of walking for multi-legged animals and robots is simpler than previously thought. That is the finding described by a team of roboticists, physicists and biologists in the Sept. 5 issue of the Proceedings of the National Academy of Sciences, in a paper titled “Walking is like slithering: a unifying, data-driven view of locomotion.”

“This is important because it will allow roboticists to build much simpler models to describe the way robots walk and move through the world,” said paper coauthor Nick Gravish, a faculty member in the Department of Mechanical and Aerospace Engineering at the University of California San Diego.

The researchers had previously studied ant walking and wanted to see how their findings could be applied to robots. In the process, they discovered a new mathematical relationship between walking, skipping, slithering and swimming in viscous fluids for multi-legged animals and bots.
