Experiments have already shown that if you want to invoke signals to explain things, the signals would have to be travelling faster than light -- more than 10,000 times the speed of light, in fact. To those who know that Einstein's relativity sets the speed of light as a universal speed limit, the idea of signals travelling 10,000 times as fast as light already sets alarm bells ringing. However, physicists have a get out: such signals might stay as 'hidden influences' -- useable for nothing, and thus not violating relativity. Only if the signals can be harnessed for faster-than-light communication do they openly contradict relativity.
