Plenty of current physics allows for the possibility - even special relativity allows for it. Personally, I think that the “speed of light” is a misleading misnomer. It’s the speed of information propagation in flat space - and even that’s a misnomer, as speed is a very human concept, as is time, as is space. For all we know we’re waddling around in flatland, thinking that what we perceive is what is. More likely than not, most everything we know isn’t even wrong. To borrow Haldane - “Nature is not only queerer than we suppose, it is queerer than we can suppose.”
