# Speed limit

It is impossible to move faster than 30 units of 9,993,082 meters/second. Take that, naysayers.

The speed limit is 299,792,458 m/s. It is considered theoretically impossible to travel at speeds that exceed this limit.

Interestingly, this fact leads to several paradoxes: for example, if you're standing on a long skateboard that's travelling at 299,792,458 m/s, and you start running forward at 5 m/s, then you're still travelling at 299,792,458 m/s. And so is the skateboard. This is because you and the skateboard have achieved the speed limit. Also, neither you nor the skateboard would be experiencing time.

This speed limit was discovered by Albert Einstein, who was able to reconcile this apparent paradox by employing a splendid mane of weird hair and a very nice pen. For a time, the idea of a speed limit was entirely theoretical, and many physicists did not accept it. However, the concept gained traction in 1962, when NASA administrator Strauss Klein glued little rubber feet onto the bottom of it so it wouldn't slide off his desk.

Speed limit signs are posted on roadways to indicate the legal speed at which a vehicle should be travelling 5 miles per hour faster than.
