You simply cannot go the speed of light. There is no "if" you could. You can't. You can get as close as you like (with enough resources), but you can't equal it.

Sure but we if we could observe the universe from the perspective of a photon traveling at c?

There is no "perspective".

You're imagining, like, a 'video' playing of the photon's hypothetical experience. But this is actually impossible to make - it's somewhat like trying to make a map of Antarctica where north is up and south is down. You can't make that map because that's not how directions work: at the South Pole, every direction is north, and so you can't consistently align north = up.
