How would you design a Time Machine for a Sci-Fi movie?

I would create an entangled wormhole with both ends here in the solar system. Then I’ll accelerate one at .999 C to a nearby star. When one end arrives at its destination, time dilation will have caused the other end to be at a different time, so by going through the wormhole, you’ll go back in time. Of course, you can’t go back in time to before the wormhole was created.

A great big Grandfather clock. Big enough for controls & just enough room to lay comfortably in the “cockpit.” A single seater machine, no passengers.

So this is a little off subject, but it seems appropriate enough. Long ago I hit on a surprisingly simple formula for building a real time machine and as it turns out, it’s pretty simple. Here is the two step process, but let’s keep it between us for now.

1) Build a Time Machine
2) Go back in time and tell yourself how you did it.

Not sure if that helps. I’ll be back later with a more on-topic response.

I’d stick a flux capacitor in an old DeLorean

Sure, a flux capacator and an old DeLorean will get the job done easy enough, but don’t be a slave to the status quo. I’d use a Lotus Evora, myself…

I’d want my time machine to be an app on my iPhone.

@HungryGuy Excellent proposal. I’d guess that going back so far the wormhole hadn’t been created might be bad for the time traveler’s health.

@ucme Sounds like H.G. Wells The Time Machine.

@crazyivan Ha! That has a good chance of working. But it is going to take a little time.

@talljasperman Works for me! :-)

@RareDenver Sorry, no DeLoreans allowed. See the last line of the question details. Besides, @HungryGuy is right. The Lotus Evora is a much sexier looking ride. :-)

@Austinlad Great idea. A downloadable Time Machine.

@crazyivan

Already on it. I’m just waiting for my future self to tell me how to do it.
