Yes, it requires infinite energy for any mass to get to light speed.
I don’t think our understanding of physics breaks down at such extremes though. I believe it’s decently understood, as in general and special relativity. I’m not a physicist though.
Doesn’t it also require infinite energy to do so if “the thing” has mass at all?
ie. Our description of physics breaks down at such extremes, so in truth, we have no fuckin’ idea, just a best guess? (Thus far)

It’s my understanding that whenever infinity is encountered, it means that our model doesn’t quite work.
It may be the way it is with this particular model/equations/bit of physics, and it may simply indicate “Nope”. I suspect not though.
