While mapping the so-called "cosmic microwave background," which is the light left over from the early universe, scientist Ranga-Ram Chary found what he called a mysterious glow, the International Business Times reported.
Chary, a researcher at the European Space Agency's Planck Space Telescope data center at CalTech, said the glow could be due to matter from a neighboring universe "leaking" into ours.

The thick line and diamonds indicate the spectrum of a 4◦ spot at (l, b = 83.6◦, −69.4◦) where the SNR of the residual 143 GHz emission is greater than 5 and where the 143 GHz emission is in excess of the residual at 100 and 217 GHz.

The properties of our observable Universe have recently been characterized in unprecedented detail through analysis of the cosmic microwave background fluctuations, a relic of the hot Big Bang. The fine tuning of parameters in the early Universe 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 than the ones we have measured for our Universe. Collision between these regions, if they occur, should leave signatures of anisotropy in the cosmic microwave background but have not yet been seen. Here, we analyze the spectral properties of masked, foregroundcleaned Planck maps between 100 and 545 GHz. We find convincing evidence for residual excess emission in the 143 GHz band in the direction of CMB cold spots which is well correlated with corresponding emission at 100 GHz. The median residual 100 to 143 GHz intensity ratio is consistent with Galactic synchrotron emission with a
spectrum. In addition, we find a small set of ∼ 2−4 degrees regions which 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
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, it could also possibly be due to the collision of our Universe with an alternate Universe whose baryon to photon ratio is a factor of ∼65 larger than ours. The dominant systematic source of uncertainty in the conclusion remains residual foreground emission from the Galaxy which can be mitigated through narrow band spectral mapping in the millimeter bands by future missions and through deeperobservations at 100 and 217 GHz.
