We’ve finally found gravitational waves, so can we time travel?

Posted by in categories: cosmology, physics, time travel

Physicists working with a powerful observatory on Earth announced Thursday that they have finally detected ripples in space and time created by two colliding black holes, confirming a prediction made by Albert Einstein 100 years ago.

These ripples in the fabric of space-time, called gravitational waves, were created by the merger of two massive black holes 1.3 billion years ago. The Laser Interferometer Gravitational-Wave Observatory (LIGO) on Earth detected them on Sept. 14, 2015, and scientists evaluated their findings and put them through the peer review process before publicly disclosing the landmark discovery today.

Is This Ancient Greek ‘Laptop’ Proof That Time Travel Is Real?

Posted by in categories: computing, time travel

It’s clearly some kind of jewelry or small weapon case, not a freaking laptop.
But just for arguments sake, why would advanced time travelers be using laptops at all? Why not a tablet? Oh god, now they’re going to go over every single ancient depiction of a person looking at a tablet and say it’s from the future. That would have made the library at Alexandria the ancient equivalent to a Best Buy big box store in our time…

Oh god, what have I done?
Too bad I can’t go back in time and…errr.
wink

The Secret to Everyday Time Travel Is Simple, Insane

Posted by in categories: particle physics, quantum physics, time travel

Since you first started learning about the world, you’ve known that cause leads to effect. Everything that’s ever happened to or near you has reiterated this point, making it seem like a fundamental law of nature. It isn’t.

It is, in fact, possible for an event to occur before its causal factors have manifested or happened. This isn’t how appliances work — you don’t have to worry about will have having left the oven on — but it is how particle physics works. It’s also the key to explaining how time travel, under the laws of quantum physics, could operate.

Could Time Travel Soon Become a Reality? Physicists Simulate Sending Quantum light Particles into the Past

Posted by in categories: evolution, particle physics, quantum physics, time travel

If a time traveler went back in time and stopped their own grandparents from meeting, would they prevent their own birth?

That’s the crux of an infamous theory known as the ‘grandfather paradox’, which is often said to mean time travel is impossible — but some researchers think otherwise. A group of scientists have simulated how time-travelling photons might behave, suggesting that, at the quantum level, the grandfather paradox could be resolved.

The research was carried out by a team of researchers at the University of Queensland in Australia and their results are published in the journal Nature Communications. The study used photons — single particles of light — to simulate quantum particles travelling back through time. By studying their behavior, the scientists revealed possible bizarre aspects of modern physics.

Warp drive and wormholes could be used for time travel, says physicist

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

Older, but interesting idea—


Warp drive and stargate wormholes could be used for time travel to the past. That’s the surprising conclusion that controversial theoretical physicist and author Dr. Jack Sarfatti has reached from his research into dark energy and dark matter.

Computing with time travel?

Posted by in categories: computing, quantum physics, time travel

Why send a message back in time, but lock it so that no one can ever read the contents? Because it may be the key to solving currently intractable problems. That’s the claim of an international collaboration who have just published a paper in npj Quantum Information.

It turns out that an unopened message can be exceedingly useful. This is true if the experimenter entangles the message with some other system in the laboratory before sending it. Entanglement, a strange effect only possible in the realm of quantum physics, creates correlations between the time-travelling message and the laboratory system. These correlations can fuel a quantum computation.

Around ten years ago researcher Dave Bacon, now at Google, showed that a time-travelling quantum computer could quickly solve a group of problems, known as NP-complete, which mathematicians have lumped together as being hard.

Australian Physicists Prove Time Travel is Possible

Posted by in categories: particle physics, quantum physics, time travel

Scientists from the University of Queensland have used photons (single particles of light) to simulate quantum particles travelling through time. The research is cutting edge and the results could be dramatic!

Their research, entitled “Experimental simulation of closed timelike curves “, is published in the latest issue of Nature Communications. The grandfather paradox states that if a time traveler were to go back in time, he could accidentally prevent his grandparents from meeting, and thus prevent his own birth.

However, if he had never been born, he could never have traveled back in time, in the first place. The paradoxes are largely caused by Einstein’s theory of relativity, and the solution to it, the Gödel metric.

Light-Bending Microchip Could Fire Up Quantum Computers

Posted by in categories: computing, quantum physics, time travel

For the first time, scientists have achieved infinite speeds on a microchip. Although this advance will not enable faster-than-light starships, the light-warping technology behind this innovation could lead to new light-based microchips and help enable powerful quantum computers, researchers said.

Light travels at the speed of about 670 million miles per hour (1.08 billion km/h) in a vacuum, and is theoretically the fastest possible speed at which matter or energy can travel. Exceeding this speed limit should lead to impossible results such as time travel, according to Einstein’s theory of relativity.

However, in a way, researchers have overcome this barrier for decades. [Warped Physics: 10 Effects of Faster-Than-Light Travel].
