No ob<x>ject with mass. ob<x>jects without mass are theoretically capable. It's all part of General Relativity theory which states that ob<x>jects increase in mass as they increase in speed. As reach the speed of light, they acquire infinite mass. This would required infinite energy to propel the ob<x>ject, making it impossible. Also 'dought' is spelled, "doubt" :o)

thanks for responce. For statement to be correct should there not be a stationary point in space to work out the speed. Not another observer moving at an unknown speed through space.
Don't forget a moving object can not detect any movement through space on it's own. speed is calculated between two objects, not space.
Sorry about spelling sometimes my mind gets in front of my fingers.

No worries. I don't think that there are any truly stationary points in space, rather, there is the object of the greatest mass (and therefore, gravitational influence). This object, apart from former a marker, creates the problem with it's effect on the travelling object's mass. Wow, Einstein and Newtown both turn up on EP in the same question :o) How cool !

That`s not exactly right, some ob<x>jects can, like tachyons, a more precise wording would be "no ob<x>ject that has mass can be accelerated to or beyond the speed of light in empty space". The empty space bit is important because light slows down in water ( and presumably some other liquids ) so it`s possible that underwater we can cause particles to move faster than it, for exemple the radiation emitted by the rods in nuclear reactors.

anywhere there is darkness could be somthing traveling faster than light, being that the light isnt fast enough to reflect of its surface ......right?

The people at CERN thought they beat the speed limit, but their data was refuted later.
