Our search for evidence of the multiverse just got a little more interesting. This week, New Scientist shared the intriguing research of Dr. Ranga-Ram Chary. Using a map of the cosmic microwave background (CMB) and subtracting it from a picture of the entire sky, he discovered an unexpected “eerie glow.”
This glow, according to the data, would have existed not too long after the Big Bang, perhaps within “a few hundred thousand years.” And it may indicate a collision that once occurred between a parallel “bubble universe” and our own.
If true, this could mean that our universe exists within a multiverse as one of many “bubble universes,” each with their own rules and histories. According to New Scientist, “like compositions on the same theme, each universe produced this way would be likely to have its own spin on physics.”
But let’s not get too ahead of ourselves. The data needs to be analyzed further, and some are pointing out that this “glow” could actually be dust, similar to what happened with BICEP2 last year. But every little step is an exciting possibility.
