Report Whoa... in General Posted December 5, 2006 I don't believe any object would be able to sustain traveling at the speed of light. See when two cars traveling at say, 50km per hour crash into one and another the force of the impact is 100km per hour on both cars. Or if just one car at a 100km per hour crashes into say a tree, the force of impact on the tree and the car is 100km per hour. So, if you apply this to traveling at the speed of light, any object that the object traveling at the speed of light came into contact with – even a very small object such as pebble – would have very damaging effects. A Kleenex box traveling at 40km per hour can give a person a serious concussion.
