In the 1985 film, Back to the Future, my mentor, Doc Emmett Brown turned a DeLorean
into a functioning time machine by outfitting it with a Flux Capacitor. To function, it
requires the car to travel at 88 mph, and uses 1.21 jigawatts of operational power.
When working, the DeLorean opens a portal in spacetime in front of the car, which it
then drives through.
The portal is open for a very short time. Since you want to take your time machine with
you, you want your whole time machine (the DeLorean) to go through the portal.
A DeLorean is 4.27 meters long.
88 mph is 39.34 meters per second.
How long is the portal open?
