Why can't there be a tie in gymnastics?

Question

In swimming or running, if you get the same time, you tie and both win a medal. The same is true in most track events. Why not gymnastics? If the judges score two gymnasts the same, is that not a tie? It seems like a dumb rule to me.

Answer 1

The probability for a tie is very slim. :-)

Answer 2

It is an IOC rule not a FIG rule. They don't allow two gold medals.  

Answer 3

I think they can only if its not a tied gold-medal win

Answer 4

The IOC won't let it happen in the Olympics. If this would have happened at Worlds they would have both gotten the gold medal.
