In a first attempt to find observational evidence of the multivers, the team from London and Canada is using a computer algorithm to survey the cosmic microwave background (CMB) radiation left over from the Big Bang in search of disk-like patterns where our bubble may have collided with other bubbles. The CMB data from NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) hasn’t given them enough information to either confirm or rule out any collisions, but new data (available to the public in 2013) from the European Space Agency’s Planck satellite will help them further their search.

Greene said in his interview with NPR that another source of observational evidence of the multiverse could be the Large Hadron Collider in Switzerland. String theory predicts that each universe is on its own “membrane,” and according to Greene, we can think of the multiverse as a cosmic loaf of bread where each slice is a separate universe. When scientists at the LHC smash protons into each other at unbelievable speeds, he said, it’s possible that remnants of the collisions could spin off of our slice of bread, leaving less energy after the collision than before it, which would otherwise be impossible according to the law of conservation of energy.
