I haven't checked this thread for several days, but because you called... There are two significant issues with objects going faster than light.* (a) It would take an infinite amount of energy to accelerate the object to that speed. (b) In some frames of reference causality would be violated--the object would arrive at its destination before it leaves its origin. I.e. it would be moving backwards in time.Arch. I am religious. And as I said earlier, I believe things that aren't logical or provable with physical evidence. I'm just honest about it.
Now, I'm not the smartest science person around, but if something was going 8x the speed of light, I don't think a human eye would be able to see it, let alone get a picture of it. @colton would probably know that one, I think.
That's only for some frames of reference, though. In others it would just look like it's going REALLY FAST. Seeing the object/getting a picture of the object wouldn't be a problem though... you'd be seeing/getting a picture of photons bouncing off of the object, and those photons would just be regular photons traveling at the speed of light.
*This is according to Einstein's theory of special relativity. Now you might say that that theory could be wrong/incomplete. However, it's been tested a tremendous amount of times and has held up completely accurately to the tests, so even if it's wrong/incomplete, the correct/complete version of the theory would almost certainly still have these two issues.
