Why do some scientists think we cant go faster thean light speed?

Alpha Beta say: The math did not show we could not move faster than sound. The math DOES show we cannot move at light speed; it would require infinite energy to move a mass (matter) to light speed. Photons have no mass, so they can move at that speed. As odd as it sounds, it's true.

Quadrillian say: It's called reality versus fiction.

Just because scientists were wrong once does not mean they will be wrong again.

The supply of geniuses has dried up. SO has the supply of technological innovation. There is no such thing as technology to go faster than light, and even if there was, people have become so dumbed down nowadays that there is noone left who could invent them.

Cheers!

No they didn't - journalists hyped the story to sell papers while scientists went ahead and did it!

"Mass becoming infinite at the speed of light is just a theory"

A very well proven one, though you obviously have no clue what a theory is! Here's a hint - it's not a guess!

Bill say: Some Scientists??? ALL Scientists KNOW that we can not exceed the speed of Light.
