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...

• 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.
• Wormho...

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...

• 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...

• 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-travel...

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.

As wi...

For 55 years, Doctor Who has chronicled the adventures across time and space of the Doctor and his/her human companions. Their means of transportation was a big blue box known as the TARDIS (Time and Relative Dimension in Space) that can take them anywhere, and anywhen, they want...
