"The future ain't what it used to be."

Open string for time machine models & designs



Here we go, I opened this string to discuss the different machines & methods for time travel. This is open to the discussion of theories (Light speed, anti-matter, black holes, relativity), medium of transportation (black holes, portals, atomic manipulation, cryogenics, tesla coils, etc...) and patents. I would also like some information on projects & developments in the time travel world.
Those topics have been discussed many times on this site over the years.
