Scientists Now Believe Quantum Entanglement May Apply to Time Itself

Bild
( TMU ) — The discoveries made over the last century by physicists studying quantum mechanics—some of which suggest that reality is only made certain by the presence of a conscious observer—is nothing short of mind-blowing. One particular concept, entanglement, was so out there that Albert Einstein called it “ spooky action at a distance ” and for many years refused to accept it as true.  But now, a new experiment has scientists believing that quantum entanglement doesn’t just apply to spatial gaps, but time itself. Einstein famously battled with physicist Niel Bohr over the predictions and theories of quantum mechanics, such as the wave function. He also corresponded with Erwin Schrödinger — yes, of Schrödinger’s cat — and in one of his 1935 letters, Einstein stated: “I know of course how the hocus pocus works mathematically. But I do not like such a theory.” The principle of entanglement held that it was impossible to independently describe two quantum systems that ha...

You Get More Introverted With Age, According to Science

Even though I’m a classic introvert , it was normal for me in my teens and early twenties to spend almost every weekend with friends. Now, in my mid-thirties, the perfect weekend is one with zero social plans. I’m not the only one who’s slowing down socially with age. Take, for example, my extroverted college friend who ran through her contact list, making phone calls to chitchat, every time she was alone in her car. She couldn’t be without human contact for even the 10 or 15 minutes it took to drive to the grocery store. These days, as a 30-something, she’s content to spend most nights at home with her family. I haven’t gotten one of her infamous calls in years. So what gives? Do we get more introverted as we get older? Probably, according to Susan Cain, author of the bestselling book Quiet: The Power of Introverts in a World That Can’t Stop Talking — and this is actually a good thing. Let me explain. Why We Become More Introverted With Age In a post on Quiet Revolution , Cain...

‘World first’ space discovery as water found on potentially habitable super-earth | 7NEWS.com.au

Scientists in the UK have made a “world first” discovery on a distant planet that hosts both water and temperatures which could support life. Water vapour has been detected on a potentially habitable super-earth known as K2-18b, located about 110 light years away. Watch the video above The exoplanet was first spotted in 2015 by NASA’s Kepler spacecraft but analysis of data has revealed new details that have not been seen on a super-earth before. K2-18b is classed as a super-earth because it is bigger than our earth – twice as big in fact, as well as eight times heavier. Current equipment is only able to determine basic factors such as distance, mass and temperature but sophisticated tools developed at University College London have been able to translate existing data from the Hubble Space Telescope to make sense of the unique molecule signatures of water vapour. K2-18b is too far away for astronomers to see, but they can look at how starlight is filtered through the planet’s atm...
