If we ever become an species spanning multiple solar systems I wonder how communication tech will evolve to help reduce ~4 years down to well anything else lol
It would take some discovery that required rewriting the laws of physics, and a lot of what we currently think we know would have to be revisited.
Yeah, that’s why the quantum world is so appealing yeah? Seemingly breaks laws of physics that it shouldn’t. My only guess for communication exceeding light speed would be somehow using quantum entanglement, but that would be thousands and thousands of years in the future I think lol.
Unfortunately, that's not how that works. Quantum mechanics doesn't break the laws of physics, is was simply that previous observations were not precise enough to observe quantum effects and the models we used before were incorrect because of that. As for quantum entanglement, see this for a better explanation than I can give.
Basically the takeaway is that messages can't be passed through entanglement faster than light because it requires knowledge known by the sender to actually decode the sent message.
