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

Bild
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...

Here’s a better way to convert dog years to human years, scientists say | Science | AAAS

A biological clock governs aging in dogs just as in humans. Here’s a better way to convert dog years to human years, scientists say By Virginia Morell Nov. 15, 2019 , 3:42 PM Our Scotch collie, Buckaroo, is just shy of 14 years old. Following the long-debunked but still popular idea that one dog year equals seven human years, he’s almost a centenarian. (This “formula” may be based on average life spans of 10 and 70 years for dogs and people, respectively.) Now, researchers say they have a new formula (see calculator below)  to convert dog years to human years—one with some actual science behind it. The work is based on a relatively new concept in aging research: that chemical modifications to a person’s DNA over a lifetime create what is known as an epigenetic clock. Scientists have built a case that one such modification, the addition of methyl groups to specific DNA sequences, tracks human biological age—that is, the toll that disease, poor lifestyle, and genetics take on our...
