Yeah, and the Earth is flat.
People said for years that breaking the sound barrier in a car was impossible because of the wave created around the car wouldn't be able to form like it does in a plane.Â* It took a while, but they were proven wrong.
Even 60 years ago people didn't think we could get into outer space.Â* Now life would change drastically without and people take it for granted.Â* With our current technology and limited thinking, we cannot think of a way to go faster than light, but that doesn't mean we won't be able to overcome it in the future.

Exceeding the sound barrier and going into space didn't break Einsteins Special Theory of Relativity, reaching the speed of light does.Might I add the special theory of relativity has been proven time after time after time for around 130 years.The Lorentz transformations say(again well proven) mass increases with velocity.At the speed of light, mass is infinite, which would mean an infinite amount of energy would be required to propel something to the speed of light.There isn't an infinite amount of energy in the universe and there never will be.So an object would have to have zero mass or a negative energy density to reach the speed of light.
