Researchers have developed a new way to explore some of the most extreme environments in the universe by combining three separate branches of physics.

We spend our lives surrounded by hi-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.
Thanks to Moore’s law and a number of developments in physics, chemistry, computer science and mathematics over the past 50 years (leading to Nobel Prizes in Chemistry in 1998 and 2013) we can now carry out many experiments entirely on computers using modelling.

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.

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.

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.
In what looks like the logical extension of the plot of Interstellar – where astronauts try to hunt down another universe after the catastrophic effects of climate change destroy Earth – physicists have modelled what would happen to a chair, a scientist, and a spacecraft, if each one ended up inside the spherical wormhole of a black hole.
