Researchers close in on physics’ holy grail with ‘super’ breakthrough
Posted by Klaus Baldauf in categories: computing, physics
A team of scientists in the US has brought us a huge step closer to a superconductor capable of working at room temperature.
If humankind were to find a way to construct a large-scale superconductor that could work at room temperature, the way our energy grids and computers are built – and many other areas of daily life – would be fundamentally changed.
The phenomenon is the lack of electrical resistance and is observed in many materials when they are cooled below temperatures of around −180 degrees Celsius, making them rather limited in their application. However, a team from George Washington University in the US has revealed something that could help us finally reach what is one of the most sought-after achievements in modern physics.

School hosts students from across West Mids for physics day
Posted by Genevieve Klien in categories: physics, transportation
A DAY of science challenges and investigations run by the Institute of Physics was hosted by Rugby High School.
Teams from 12 schools from across the West Midlands came to take part in Super Physics Day.
The teams of four used their knowledge of science to conduct three timed investigations including ‘Air Drop’, an RAF challenge to drop relief packages from a plane to the desired location.

New Theory: “Mirror Image” of Our Universe Existed Before Big Bang
Posted by Michael Lance in categories: cosmology, physics
A bizarre theory could explain dark matter.
Mirror Image
The Big Bang didn’t just result in our familiar universe, according to a mind-bending new theory — it also generated a second “anti-universe” that extended backwards in time, like a mirror image of our own.

Powerful Magnetic Energy Blows Up a Lab
Posted by James Christian Smith in category: physics
In September 2018, physicists at the University of Tokyo were trying to create insanely strong magnetic energy in an indoor environment. They expected an explosion. But they didn’t know it would be so powerful that it would knock an iron door off its hinges.
How did scientists accidentally generate the longest-lasting and strongest controllable magnetic energy field in human history?

There’s a black hole that can let humans erase their past, astrophysicists say
Posted by Michael Lance in categories: cosmology, physics
Forget the past.
However, a study from Berkley University suggests that entering a specific black hole in the universe can actually erase everything that had happened in a person’s past. Not only that, it could also give humans infinite futures!
But, how is that even possible?

It’s time physics recognised that time is real
Posted by Genevieve Klien in category: physics
We all feel the forward march of time, but the laws of physics tell us it is an illusion. A radical rethink is needed, argues theoretical physicist Lee Smolin.

MIT says proton’s core generates pressure higher than inside a neutron star
Posted by Genevieve Klien in category: physics
Physicists at MIT have for the first time calculated the pressure distribution inside a proton. One incredible finding by the researchers is that the core of a proton generates pressures greater than what’s found inside a neutron star. That discovery is so incredible because a neutron star is among the densest known objects in the universe.

The known Universe just got a lot bigger
Posted by Michael Lance in categories: cosmology, physics
A new map of the night sky using the Low Frequency Array @LOFAR telescope charts hundreds of thousands of previously unknown galaxies.
The international team behind the unprecedented space survey said their discovery literally shed new light on some of the Universe’s deepest secrets, including the physics of black holes and how clusters of galaxies evolve.

There’s a black hole that could erase your past and let you live out infinite futures, study suggests
Posted by Paul Battista in categories: cosmology, physics, singularity
According to most astrophysicists, once you enter a black hole, that’s it for you: gravity will drag you to the singularity — a one-dimensional infinitely small space containing a huge mass — at the speed of light. Then, the black hole will ‘spaghettify you”. Nice.
However, a new study from Berkley University theorises not only that humans could survive going into a black hole, but that their past could be erased, giving way to “infinite futures”.
Physicist Peter Hintz argues that if a human traveller entered a “relatively benign” black hole, they might be able to shed the natural laws of physics — and survive.
