Stole this from Neogaf but it's absolutely fascinating.
Scientists claim to have created a new form of non-equilibrium matter called Time Crystals,

http://www.sciencealert.com/scientists-have-just-announced-a-brand-new-form-of-matter-time-crystals


For months now, there's been speculation that researchers might have finally created time crystals - strange crystals that have an atomic structure that repeats not just in space, but in time, putting them in perpetual motion without energy.

Now it's official - researchers have just reported in detail how to make and measure these bizarre crystals. And two independent teams of scientists claim they've actually created time crystals in the lab based off this blueprint, confirming the existence of an entirely new form of matter.



First predicted by Nobel-Prize winning theoretical physicist Frank Wilczek back in 2012, time crystals are structures that appear to have movement even at their lowest energy state, known as a ground state.

Usually when a material is in ground state, also known as the zero-point energy of a system, it means movement should theoretically be impossible, because that would require it to expend energy.

But Wilczek predicted that this might not actually be the case for time crystals.

Normal crystals have an atomic structure that repeats in space - just like the carbon lattice of a diamond. But, just like a ruby or a diamond, they're motionless because they're in equilibrium in their ground state.

But time crystals have a structure that repeats in time, not just in space. And it keep oscillating in its ground state.

Imagine it like jelly - when you tap it, it repeatedly jiggles. The same thing happens in time crystals, but the big difference here is that the motion occurs without any energy.

A time crystal is like constantly oscillating jelly in its natural, ground state, and that's what makes it a whole new form of matter - non-equilibrium matter. It's incapable of sitting still.

Jupiter is in your sun sign this week, making it pretty crowded in there, what with Jupiter being the largest of the planets and all.

Me too.

I'm like a dog watching tennis, I understand that a ball is involved somehow but like hell do I know the rules of the game.

That reads like I'm high, I'm not. Unless those two codeine I just took weren't actually codeine :shifty:

Even if they were just codeine, things can get a bit wavy.

It's really simple guys, I would explain it, but I don't want to be a show off. I'll let someone else do it instead.

True but they were only 15mg tablets so probably not enough to alter my thought process.

I've only had that happen once when I was in agony with a pressure sore and took the maximum recommended dose, I felt like I had ADD and couldn't concentrate on anything for longer than 10 minutes.

Human-Pig Hybrid Created in the Lab
Scientists hope the chimera embryos represent key steps toward life-saving lab-grown organs.

This pig embryo was injected with human cells early in its development and grew to be four weeks old.

I’ve slept with some utter pigs before so I think I was just ahead of the times.

A giant black hole ripped apart a star and then gorged on its remains for about a decade, according to astronomers. This is more than ten times longer than any observed episode of a star’s death by black hole.

Researchers made this discovery using data from NASA’s Chandra X-ray Observatory and Swift satellite as well as ESA’s XMM-Newton.

The trio of orbiting X-ray telescopes found evidence for a “tidal disruption event” (TDE), wherein the tidal forces due to the intense gravity from a black hole can destroy an object – such as a star – that wanders too close. During a TDE, some of the stellar debris is flung outward at high speeds, while the rest falls toward the black hole. As it travels inwards to be ingested by the black hole, the material heats up to millions of degrees and generates a distinct X-ray flare.

“We have witnessed a star’s spectacular and prolonged demise,” said Dacheng Lin from the University of New Hampshire in Durham, New Hampshire, who led the study. “Dozens of tidal disruption events have been detected since the 1990s, but none that remained bright for nearly as long as this one.”

The extraordinary long bright phase of this event spanning over ten years means that among observed TDEs this was either the most massive star ever to be completely torn apart during one of these events, or the first where a smaller star was completely torn apart.

The X-ray source containing this force-fed black hole, known by its abbreviated name of XJ1500+0154, is located in a small galaxy about 1.8 billion light years from Earth.

The source was not detected in a Chandra observation on April 2nd, 2005, but was detected in an XMM-Newton observation on July 23rd, 2005, and reached peak brightness in a Chandra observation on June 5, 2008. These observations show that the source became at least 100 times brighter in X-rays. Since then, Chandra, Swift, and XMM-Newton have observed it multiple times.

The sharp X-ray vision of Chandra data shows that XJ1500+0154 is located at the center of its host galaxy, the expected location for a supermassive black hole.

The X-ray data also indicate that radiation from material surrounding this black hole has consistently surpassed the so-called Eddington limit, defined by a balance between the outward pressure of radiation from the hot gas and the inward pull of the gravity of the black hole.

“For most of the time we’ve been looking at this object, it has been growing rapidly,” said co-author James Guillochon of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. “This tells us something unusual – like a star twice as heavy as our Sun – is being fed into the black hole.”

The conclusion that supermassive black holes can grow, from TDEs and perhaps other means, at rates above those corresponding to the Eddington limit has important implications. Such rapid growth may help explain how supermassive black holes were able to reach masses about a billion times higher than the sun when the universe was only about a billion years old.

“This event shows that black holes really can grow at extraordinarily high rates,” said co-author Stefanie Komossa of QianNan Normal University for Nationalities in Duyun City, China. “This may help understand how precocious black holes came to be.”

Based on the modeling by the researchers the black hole’s feeding supply should be significantly reduced in the next decade. This would result in XJ1500+0154 fading in X-ray brightness over the next several years.

Now scientists are solving real problems like Tomato sauce getting stuck in the bottle.
They can forget about the Higgs Boson this is the real breakthrough of the century.

Can this be applied to my bum so I don't have to wipe? Will save me £££s on refrigeration costs alone.
