Julian Barbour on “The Janus Point: A New Theory of Time” | Closer To Truth Chats

Posted by in category: quantum physics

Physicist Julian Barbour discusses his newest book, “The Janus Point: A New Theory of Time.” In it, Barbour makes the radical argument that the growth of order drives the passage of time — and shapes the destiny of the universe.

How touch dampens the brain’s response to painful stimuli

Posted by in category: neuroscience

When we press our temples to soothe an aching head or rub an elbow after an unexpected blow, it often brings some relief. It is believed that pain-responsive cells in the brain quiet down when these neurons also receive touch inputs, say scientists at MIT’s McGovern Institute for Brain Research, who for the first time have watched this phenomenon play out in the brains of mice.

The team’s discovery, reported Nov. 6 in the journal Science Advances, offers researchers a deeper understanding of the complicated relationship between pain and touch and could offer some insights into chronic pain in humans.

“We’re interested in this because it’s a common human experience,” says McGovern investigator Fan Wang. “When some part of your body hurts, you rub it, right? We know touch can alleviate pain in this way.” But, she says, the phenomenon has been very difficult for neuroscientists to study.

Shocking decline in human sperm counts

Posted by in category: chemistry

A study in the journal Human Reproduction finds that human sperm counts fell by 62% in the last 50 years, possibly a result of poor diets and a toxic soup of forever chemicals in air and water.

How to Build A Time Machine — Paul Davies

Posted by in categories: cosmology, space travel, time travel

Time travel makes great science fiction, but can it really be done? Travel into the future is already a reality, but visiting the past is a much tougher proposition, and may require fantastic resources such as a wormhole in space. Nevertheless, if going back in time is allowed, even in principle, then what about all those paradoxes that make time travel stories so intriguing?

Paul Davies is a physicist, cosmologist and astrobiologist at Arizona State University, where he is Director of the Beyond Center for Fundamental Concepts in Science. He is the author of many books, including “How to Build a Time Machine” and, most recently, “The Eerie Silence: are we alone in the universe?”

Is It Possible to Build a Time Machine? With Paul Davies

Posted by in categories: media & arts, physics, time travel

Time travel is one of sci-fi’s favorite tools. But is it possible to build a real time machine? Could you travel into the future or the past? Paul Davies joins John Michael Godlier to discuss the possibilities of time travel and how it would work within Einstein’s theory of general relativity.

Paul Davies is a theoretical physicist and regents professor at the department of physics at Arizona State University. He is a cosmologist, astrobiologist and best-selling science author, including the author of How to Build a Time Machine.
