Also, due to length contraction, at light speed the universe isn’t 96 billion light years wide, it’s 0 anything wide.
At light speed there is no time and no distance, the origin is the destination. You won’t even experience a single tick of Planck time to get there. Instantaneous.
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)
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.
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.
AFAIK the observable universe is limited by the parts of space which expand faster than the speed of light.
Some billions of years later and we might have not seen other galaxies at all, maybe we are lucky.
