Following is a transcript of the video. Brian Greene: “I’m Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival. “It’s critical that you realise that there are two types of time travel, and they are radically different. Time travel to the future? Definitely possible. “We know how to do it because Einstein showed us the way over a hundred years ago. It’s surprising how few people actually really know about this in their bones. He showed that if you go out into space and travel near the speed of light, and you turn around, and you come back, your clock will be ticking off time more slowly. So, when you step off it’s going to be the future on planet Earth.
Video advice: Mysterious Portals That Lead to Another Dimension, Discovered Throughout the Planet!
Antique doors and gateways can be found all over the world. Though, some of these doors may be much more than they appear on the surface. Throughout history, researchers have wondered if there may be portals to other dimensions scattered all around us. We have found the locations of many ancient doorways that seem to serve no purpose – at least not in modern times. Though, many theorists have begun to wonder if such doorways may have once been used by humans or giants as a way to travel through different dimensions – maybe even to other planets.
Video advice: ScienceCasts: Hidden Magnetic Portals Around Earth
A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet to that of the sun.
[FAQ]
Do wormholes exist on Earth?
To create a wormhole on Earth, we'd first need a black hole. ... Plus, in the 1960s theorists showed that wormholes would be incredibly unstable. It could be possible to stabilise the wormhole using so-called 'exotic matter', whose existence is predicted by quantum theory.
Where are portals located on Earth?
They're typically located a few tens of thousands of kilometers from Earth where the geomagnetic field meets the onrushing solar wind. Most portals are small and short-lived; others are yawning, vast, and sustained.
Does spacetime exist on Earth?
There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein's theory of gravity. ... Gravity, says Einstein, is simply the motion of objects following the curvaceous lines of the dimple.
Will it ever be possible to travel back in time?
Time travel is theoretically possible, new calculations show. ... Time travel is possible based on the laws of physics, according to new calculations from researchers at the University of Queensland. But time-travelers wouldn't be able to alter the past in a measurable way, they say — the future would stay the same.
Are white holes real in space?
Why white holes don't exist While general relativity describes white holes in theory, no one knows how one might actually form. ... Even if large white holes did form, they probably wouldn't hang around too long. Any outgoing matter would collide with the matter in orbit, and the system would collapse into a black hole.
