Theories On Travelling To Your Past

  • In 2013, physicists Benjamin K. Tippett and David Tsang published a paper proposing a theoretical means of creating an actual retrograde-capable time machine: a way to travel to your own past. 
  • Tippett and Tsang describe a bubble of spacetime containing a time-traveler entering a Closed Timelike Curve (essentially the same as an Einstein-Rosen bridge). Within that curve, the traveler can go anywhere on his or her own timeline, while within the bubble time seems to pass normally.
  • The two physicists even theorized that timelike curves could be split and connected, opening up the possibility of traveling not just along your own timeline — but anywhere in time and space.

The Einstein–Rosen Bridges

An Einstein-Rosen bridge is a shortcut through space caused by the warping of spacetime. Massive objects like stars or black holes bend time and space like a bowling ball on a trampoline. A massive enough object could bend spacetime to create a connection between two otherwis...

Hyperdrive

Hyperspace is best understood as a sub-region of our real space where the same physical laws don’t apply. Hyperspace has no theoretical basis like Einstein-Rosen bridges or warp drives.

This universe doesn’t seem to allow faster-than-light travel. The solution: just don...

Jump Drives

The Jump Drives in Battlestar Galactica made interstellar teleportation possible with virtually no delay. Both human ships and their Cylon counterparts used FTL drives. We were also told that when a ship jumps, it warps the space around it and can damage other nearby vessels.

Wormhole Representations

Wormhole Representations

  • The entrance to a wormhole has often been represented as a tube, which makes sense given the name. But it’s also inaccurate. Interstellar, in one of its most intense scenes, got it right. From our perspective in 3-D space, a wormhole should look like a sphere.

Warp Engines

Warp Engines

Warp technology is synonymous with the Star Trek series.

Like an Einstein-Rosen bridge, warp technology skirts around the impossibility of accelerating a ship past the speed of light. Instead, a warp drive bends space itself. It compresses space in front of the cra...

The Possibility Of Warp Engines

  • Warp technology may be possible in reality.
  • In 1994, theoretical physicist Miguel Alcubierre proposed a means of FTL space travel consistent with general relativity. Inspired by Star Trek, Alcubierre described an engine creating an energy field with lower density than the vacuum of s...

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
