Black Holes May Explode Into ‘White Holes’ And Pour All Their Matter Into Space, Physicists Say

Black holes might end their lives by transforming into their exact opposite — ‘white holes’ that explosively pour all the material they ever swallowed into space, say two physicists. The suggestion, based on a speculative quantum theory of gravity, could solve a long-standing conundrum about whether black holes destroy information.

The theory suggests that the transition from black hole to white hole would take place right after the initial formation of the black hole, but because gravity dilates time, outside observers would see the black hole lasting billions or trillions of years or more, depending on its size. If the authors are correct, tiny black holes that formed during the very early history of the Universe would now be ready to pop off like firecrackers and might be detected as high-energy cosmic rays or other radiation. In fact, they say, their work could imply that some of the dramatic flares commonly considered to be supernova explosions could in fact be the dying throes of tiny black holes that formed shortly after the Big Bang.

We Are Not Alone In Universe, NASA Scientists Say

It’s highly unlikely we’re alone in the universe, NASA experts are saying, and we may be close to finding alien life. In fact, it may happen in the next two decades.

NASA held a panel discussion at the agency’s Washington headquarters on Monday, where space experts talked about the search for Earth-like planets that host life. Based on recent advancements in space telescope technology, scientists estimated that in the coming decades we’ll confirm suspicions that we’re not alone.

“I think in the next 20 years we will find out we are not alone in the universe,” NASA astronomer Kevin Hand said in footage filmed at the discussion and posted on YouTube.

If The Earth Stopped Spinning, Some Really Bad Things Would Happen

Sometimes it's easy to forget that the Earth and everything on it are rotating. But it's a good thing that our planet keeps spinning, because if it suddenly stopped it would unleash a torrent of catastrophes.

Just listen to what Michael Stevens has to say in this new installment of his Vsauce YouTube series.

"First of all, you would gain weight," Stevens says, a reference to the fact the Earth's rotation slightly offsets the effect of gravity. "But that would be the least of your worries."

Eye-tracking wheelchair helps the severely disabled steer new course

Scientists in London have developed an algorithm-based decoder system that enables wheelchair users to move around simply by looking to where they wish to travel. The researchers at Imperial College London say the system is inexpensive and easy to use and could transform the lives of people who are unable to use their limbs.
Algorithms working with inexpensive software could help quadriplegics steer wheelchairs simply by looking in their desired direction of travel. An Imperial College London team says their newly devised system can read eye movements to tell if a person is merely gazing or wants to move. Co-designer and student Kirubin Pillay says it’s simple to use.

Nearly 80 percent of young people in the United States who die are killed by injuries, and more than half of these injuries are unintentional, such as those sustained in car crashes, falls or fires, according to a new report.

Researchers looked at all people ages 1 to 30 in the United States who died in 2010, and found that 79 percent of deaths in that group were from injuries; while 20 percent were from chronic diseases such as heart disease or cancer, and 1 percent were due to infections, the report said.

Of the deaths among young people that were due to injuries, about 60 percent were a result of unintentional injuries, while 20 percent were due to suicide, and another 20 percent to homicide.

These Bears Are Having Lots Of Oral Sex, And Scientists Think They Know Why

Birds do it. Bees do it. Bears do it too–but some bears do it a bit differently.

Researchers from Poland are reporting that a pair of male brown bears at a zoo in Croatia have been engaging in oral sex–and lots of it. Over the course of 116 hours of recent observation, the animals engaged in fellatio 28 times. That’s about one act of fellatio for every four hours, with each act ranging in duration from 1 minute to 4 minutes.

Penis Size Study Shows Women Want One Thing For Flings, Another For Long Relationships

For one-night stands, size does matter, but it’s not penis length that women are concerned about — it’s girth, a new study suggests.

In the study, 41 women viewed and handled penises made on a 3D printer. The models were blue, and ranged in size from 4 inches long and 2.5 inches in circumference to 8.5 inches long and 7 inches in circumference. They were asked to pick which of the 33 models they would prefer for a one-time partner, and which they would prefer for a long-term partner.

For one night stands, women selected penis models with slightly larger girth, on average, than those they selected for long-term relationships.

This Amazing Shot Of 10,000 Galaxies May Be The Hubble Telescope’s Most Revealing Photo Ever

NASA calls it the most colorful image ever captured by the Hubble Space Telescope–and the most comprehensive. It has to be one of the most spectacular.

But the image–the remarkable payoff of a new survey called the Ultraviolet Coverage of the Hubble Ultra Deep Field–is more than merely beautiful. It may also help fill in some gaps in our understanding of how stars form.

Freedom From What Others Think

In this life-affirming video, Sue Austin goes where few have been… in her wheelchair. Refusing to be defined by pity or limitations, she proves that we can’t let ourselves be defined by how other people see us — and that telling our own story sets us free.
