#TimeTravel

When would you travel to?

Physicists have confirmed the existence of a new form of atomic nuclei, and the fact that it’s not symmetrical challenges the fundamental theories of physics that explain our Universe.

But that’s not as bad as it sounds, because the 2016 discovery could help scientists solve one of the biggest mysteries in theoretical physics — where is all the dark matter? — and could also explain why travelling backwards in time might actually be impossible.

As the common tropes of science fiction continue to break out into reality, from humanoid robots to self-driving cars, there’s one concept that has seemingly remained beyond our grasp: time travel.

But, jumping through time might not be impossible, after all, according to one astrophysicist.

This was the second scholarly paper i saw this year about time travel. Posting because there isn’t nearly enough serious interest about Time Travel in the science community.

Traversable acausal retrograde domains in spacetime.

Abstract
In this paper we present geometry which has been designed to fit a layperson’s description of a ‘time machine’. It is a box which allows those within it to travel backwards and forwards through time and space, as interpreted by an external observer. Timelike observers travel within the interior of a ‘bubble’ of geometry which moves along a circular, acausal trajectory through spacetime. If certain timelike observers inside the bubble maintain a persistent acceleration, their worldlines will close.

In Unexpected Futurist, we profile the lesser known futurist side of influential individuals. This episode’s unexpected time-traveler: Benjamin Franklin. Ben Franklin was an inventor, observer, electricity pioneer, and serial experimenter, so it’s not entirely surprising he looked to the future. But it turns out he was looking to the far, far future. In 1780 he wrote a letter to a friend in which he lamented that he was born during the dawn of science.

Sometimes, albeit rarely, people object to rejuvenation biotechnologies saying that ageing has its pluses too, thus subtly implying that we should leave it alone in order not to lose these pluses. The thing is, they’re not talking about the same kind of ageing that science is trying to undo. They’re mixing up chronological and biological ageing, and they’re not at all the same thing.

This objection is very simple to explain and even simpler to dismantle, because it boils down to a gross misunderstanding.

Whoever raises this objection generally says that with ageing comes experience, that later in life people are generally happier, more accomplished, and so on. I have nothing to object to that, except that all those nice things are a (possible) consequence of chronological ageing, most definitely not of biological ageing. It is not very often that people mix the two up, but at times they do, so let us clarify once and for all what the difference is.

Chronological ageing is nothing more, nothing less than the passing of time. Becoming chronologically older simply means that the time you’ve existed for is getting longer. There’s nothing wrong with it, and no one (to my knowledge) wants to stop, ‘cure’, or reverse chronological ageing—especially because that would be a bit complicated to do and it would have annoying side-effects, such as time freezing or rewinding your life back to your elementary school years, possibly dragging the entire universe along, and would do nothing to eliminate the ill health of old age. Doesn’t sound like a lot of fun—and I speak as a chap with a thing for time travel.

We have the math locked down. Next, we need the materials.

A researcher crunches the numbers on time travel using his own TARDIS. Also, a weird new material could be the real-world version of a flux capacitor.

Physicists have come up with what they claim is a mathematical model of a theoretical “time machine” — a box that can move backwards and forwards through time and space.

The trick, they say, is to use the curvature of space-time in the Universe to bend time into a circle for hypothetical passengers sitting in the box, and that circle allows them to skip into the future and the past.

“People think of time travel as something as fiction. And we tend to think it’s not possible because we don’t actually do it,” says theoretical physicist and mathematician, Ben Tippett, from the University of British Columbia in Canada.
