7 Science Facts That Ruin Your Favourite Movies (But 2 That Make It All Better)

2. Thor: The Einstein-Rosen Bridge Is Real, And It Tells Us The Shape Of The Universe

For all the science posturing of the likes of Interstellar and Gravity, the last place you'd expect to find some hardcore theoretical physics is in the pleasingly bonkers world of the MCU. Thor, however, manages to grapple not only with some pretty complex Einsteinian ideas but also with the shape of the universe itself.

It's no revelation that the connection between Asgard and Earth is an Einstein-Rosen bridge, what with it actually being in the script and all. But the cool thing is that the very presence of such a bridge gives us a clue as to the literal shape of the MCU - and it's delicious.

First: some background. An Einstein-Rosen Bridge is a theoretical point at which spacetime curves so much that it folds back in on itself and connects two distant parts of space. A wormhole, basically.

The thing is that this just doesn't work in a "flat" universe. Any hole made in the fabric of flat spacetime would just fall into endless nothing (i.e. a black hole), but a hole in the surface of, say, a donut shaped universe, technically known as toroidal, you could conceivably fall through in spacetime and hit the other side.

Great theoretical physics, but sadly we're now just craving donuts.
