We Can’t Alter The Flow of Time But, According to Physics, We Can Bend It

Most of us have dreamed of traveling through time, backward or forwards, faster than those around us. And surprisingly, recent work has shown us that time travel is far more than just a dream. In fact, a number of researchers have explored, and are currently exploring, the legitimacy of time travel. While they haven’t quite gotten to the point where they are able to time travel themselves—these researchers have found some concrete science backing it up. This past June, I met with James Beacham, a particle physicist at the European Organization for Nuclear Research (CERN), at Brain Bar Budapest, a...

Stephen Hawking thinks he knows what happened before the beginning of time

Neil deGrasse Tyson’s show Star Talk is ending its fourth season with a bang—a big one. The big one, to be precise. The show, filmed at the American Museum of Natural History in New York City, features famous astrophysicist Tyson interviewing famous-for-things-other-than-physics folks through the lens of science. For this Sunday’s season finale, Tyson’s guest is arguably the only physicist more famous than he: Stephen Hawking. Tyson asked Hawking your standard softball interview question: what was around before the big bang? In other words, what happened before the moment the universe began? Check out his answer: “The boundary condition of...

Where Did Time Come From, and Why Does It Seem to Flow?

Paul Davies has a lot on his mind—or perhaps more accurate to say in his mind. A physicist at Arizona State University, he does research on a wide range of topics, from the abstract fields of theoretical physics and cosmology to the more concrete realm of astrobiology, the study of life in places beyond Earth. Nautilus sat down for a chat with Davies, and the discussion naturally drifted to the subject of time, a long-standing research interest of his. Here is a partial transcript of the interview, edited lightly for length and clarity. There might be some pre-geometry, that would...

How to Handle This Year's Extra Second: 'Smear' It

(NEWSER) – For many, 2016 can't end soon enough. For everyone, though, it's actually going to last one second longer than usual. With New Year's Eve approaching, outlets such as Phys.org are reminding people that an extra "leap second" will be added to the final day of 2016 in order to keep our earthly time-keeping measures in sync. No, this won't affect countdowns to ball drops—the second is incorporated into the day in far more subtle ways—but if you happened to watch the online clock counting Coordinated Universal Time, or UTC, you'd see the quirk of it going from 23:59:59...

Time for a change in the way we tell time?

Time for a change in the way we tell time?

In the appropriately named New York Times, James Gleick uses the switch from daylight to standard time to make a case for dropping time zones altogether, writing: Most people would be happy to dispense with this oddity of timekeeping, first imposed in Germany 100 years ago. But we can do better. We need to deep-six not just daylight saving time, but the whole jerry-rigged scheme of time zones that has ruled the world’s clocks for the last century and a half.... Let us all — wherever and whenever — live on what the world’s timekeepers call Coordinated Universal Time, or...
