Ah yes, string theory (or “M” theory as some like to call it) with membranes undulating in time/space each representing its own universe or dimension and when these undulations hit together from different branes (short for membranes) some believe causes another big bang and an alternate universe creation in another brane. Whereas some say that when they hit, we get black holes on the one side and white holes on the other with spillage in between creating wormholes. Fascinating and heady stuff to be sure. Imagine them proving both these theories (speed of light and string theory) at the same time in our lifetimes. One being the direct result from the other.
