Did the LIGO gravitational waves originate from primordial black holes?

Posted by in categories: cosmology, physics

Binary black holes recently discovered by the LIGO-Virgo collaboration could be primordial entities that formed just after the Big Bang, report Japanese astrophysicists.

If further data support this observation, it could mark the first confirmed finding of a primordial black hole, guiding theories about the beginnings of the universe.

In February, the LIGO-Virgo collaboration announced the first successful detection of gravitational waves.

Welcome to Lab 2.0 Where Computers Replace Experimental Science

Posted by in categories: chemistry, computing, mobile phones, physics, science, solar power, sustainability

We spend our lives surrounded by high-tech materials and chemicals that make our batteries, solar cells and mobile phones work. But developing new technologies requires time-consuming, expensive and even dangerous experiments.

Luckily we now have a secret weapon that allows us to save time, money and risk by avoiding some of these experiments: computers.

Dimensional Reduction: The Key To Physics’ Greatest Mystery?

Posted by in category: physics

Perhaps looking at our Universe as three dimensions of space is too restrictive. What if we were more — and less — all at once?

Engineer finds a huge physics discovery in da Vinci’s ‘irrelevant scribbles’

Posted by in category: physics

Until now, art historians dismissed some doodles in da Vinci’s notebooks as “irrelevant.”

But a new study from Ian Hutchings, a professor at the University of Cambridge, showed that one page of these scribbles from 1493 actually contained something groundbreaking: The first written records demonstrating the laws of friction.

Although it has been common knowledge that da Vinci conducted the first systematic study of friction (which underpins the modern science of tribology, or the study of friction, lubrication, and wear), we didn’t know how and when he came up with these ideas.

Physicists Say They’ve Figured out How Spacecraft Could Make It Through a Wormhole

Posted by in categories: climatology, cosmology, physics, space travel, sustainability

A new paper asserts that a physical body might be able to pass through a wormhole in spite of the extreme tidal forces that are at play.

A physical object, such as a person or a spacecraft, could theoretically make it through a wormhole in the centre of a black hole, and maybe even access another universe on the other side, physicists have suggested.

A Debate Over the Physics of Time

Posted by in categories: physics, space

According to our best theories of physics, the universe is a fixed block where time only appears to pass. Yet if the flow of time is an illusion, how do we account for the distinction between past, present and future? In June, 60 physicists gathered for four days at the Perimeter Institute for Theoretical Physics to debate this another questions about the mysteries of time.
