Perhaps assuming that maybe theoretically thinking undiscovered coincidences...make humans dumb&dumber.

"Not everyone is giving up. "No one promised it would be easy," says Gia Dvali, a theorist at New York University. He has developed a modified theory of gravity in which space-time is not as formless as we tend to think. According to the theory, which he developed with his colleagues Gregory Gabadadze and Massimo Porrati, space-time has a limited underlying shape that makes it look as if a weird form of energy is warping it.

The warping happens because gravitons - the as yet undiscovered particles that are presumed to carry gravity - have a small mass, and decay into other dimensions with half-lives of 15 billion years. This is strikingly similar to the age of the universe. "We don't know whether this is just a remarkable coincidence or the result of something more fundamental," says Dvali."
