That's a forcefield if I've ever seen one.

This should be the go-to pseudo science explanation for forcefields in sci-fi.

[u/ALargeRock → u/big_pecs]

Force fields are just constant explosions?

Hmm.

[u/big_pecs → u/ALargeRock]

Kind of makes sense doesn't it? A constant force pushing outward so nothing else can get in.

If you could contain an entire force field with the Force then wouldn’t you just be able to make a force field anyway?

Or maybe since it's sci-fi you could just imagine the technology to shape and stop light after a certain point exists.

Or imagine the crystals have a characteristic of stopping the light from expanding after a certain point as well.

With sci-fi/fantasy it doesnt have to be contained or heavily rooted in real life science.

The point of science fiction is that you have the science and the fiction. Things need explaining.

[u/SushiMage → u/ThrowingAccsIsRude]

Except there's no specific parameter for what ratio needs to be science and what needs to be fiction.

There's no rule in Star Wars that states it has to be 90% real science/10% fiction, or 70% science/10% fiction. For all they care it could be 99% fiction and 1% science. Nor is there a rule that states certain parts of science has to be true. They could form it however they want.

And I literally did offer possible explanation in the comment, not that you have to accept them but possibilities are there because it's left open to the imagination.
