Spectral Variations of the Sky: Constraints on Alternate Universes
R. Chary
(Submitted on 1 Oct 2015 (v1), last revised 1 Dec 2015 (this version, v2))
The fine tuning of parameters required to reproduce our present day Universe suggests that our Universe may simply be a region within an eternally
inflating super-region. Many other regions beyond our observable Universe would exist with each such region governed by a different set of physical
parameters. Collision between these regions, if they occur, should leave signatures of anisotropy in the cosmic microwave background (CMB) but have
not been seen. We analyze the spectral properties of masked, foreground-cleaned maps between 100 and 545 GHz constructed from the Planck dataset. Four
distinct $sim2-4arcdeg$ regions associated with CMB cold spots show anomalously strong 143 GHz emission but no correspondingly strong emission at
either 100 or 217 GHz. The signal to noise of this 143 GHz residual emission is at the ≳6σ level which reduces to 3.2−5.4σ after subtraction of
remaining synchrotron/free-free foregrounds. We assess different mechanisms for this residual emission and conclude that although there is a 30%
probability that noise fluctuations may cause foregrounds to fall within 3σ of the excess, there is less than a 0.5% probability that foregrounds can
explain all the excess. A plausible explanation is that the collision of our Universe with an alternate Universe whose baryon to photon ratio is a
factor of ∼4500 larger than ours, could produce enhanced Hydrogen Paschen-series emission at the epoch of recombination. Future spectral mapping and
deeper observations at 100 and 217 GHz are needed to mitigate systematics arising from unknown Galactic foregrounds and to confirm this unusual
hypothesis.

he concept of a parallel universe is well-trodden territory in science fiction (See: The CW’s Flash for a recent example), but scientists might’ve
just spotted some legitimate proof of the multiverse — and it looks like it’s leaking into ours.
As Inverse reports, the Planck telescope has been mapping the cosmic microwave background (CMB) leftover from the early days of the universe. Turns
out, it might’ve found something of cosmic importance. Caltech cosmologist Ranga-Ram Chary compared the CMB map with a shot of the night sky
captured by the Planck telescope. The effort spotted a patch of light 4,500 times brighter than it should be.
His paper posits it could be proof of another universe literally “bumping” into our own, as this collision would look very different than anything
we’ve seen before. Something 4,500 times brighter in CMB than it should be? Yeah, that seems to fit the bill. If true, it would mean this universe
bumped into ours just a few hundred thousand years after the Big Bang. It’s also possible that insane brightness could be bleeding over from a
universe packed with electrons and protons, which could account for some of the energy.
