Momentum at the speed of light

[blueberrynerd]

Hi! Need some help with this that's been plaguing my brain.

Hypothetically, if an object's speed were to be increased so as to reach the speed of light and let it gain maximum momentum, what would we perceive as happening to the object?

You just made it absorb more than the energy of the universe so that it obtained an infinite momentum. Then there's nothing anymore that can make it change its course.
