Hollywood must be afraid of Einstein considering how few movies seriously address the theory of relativity.

Here are the ones who actually face the cold truth about space travel.

It really does have everything you could want.

But it also has problemsmainly, like we said, that its massive.

That problem, as Albert Einstein tells us, is the speed of light.

This has two important consequences.

First, you arenevergoing to be as fast as a beam of light.

Heres how they addressed space travels most menacing challenge.

It also demonstrates one of the reasons why relativistic movie space travel is so rare.

But it can look like a hat on a hat.

Suddenly your space travel story is now also a time travel story.

It takes the negatives of using relativity in space travel and turns them into a positive.

The time dilation becomes simply another twist of the knife of isolation and dehumanisation that permeates the film.

Many regardDark Staras a prototype forAlien.

AndAlienis an interesting case study of Hollywoods discomfort around the passage of time during space travel.

That film sees its crew start the film waking up from hypersleep.

But ultimately, to deliver the happy ending Hollywood demands,Flight of the Navigatorhas to fudge the science.

This will be the first of many such fudges.

Interstellar (2014)

Christopher Nolans space exploration flick is probablythe most famous take on time dilation.

It is, it has to be said, a film that has done its homework.

Well, not yet.

But people are trying.

In short, it is perfect movie fodder.

The film rights to the book have been changing hands since 1988.
