Bruised Universe

Bruised Universe

Well, doesn’t it just figure that right on the heels of commenting on an article that proposes life after death involves the human soul entering another universe, I should find another article that proposes evidence of other universes.

Astronomers Find First Evidence of Other Universes

Our cosmos was “bruised” in collisions with other universes. Now astronomers have found the first evidence of these impacts in the cosmic microwave background.

There’s something exciting afoot in the world of cosmology. Last month, Roger Penrose at the University of Oxford and Vahe Gurzadyan at Yerevan State University in Armenia announced that they had found patterns of concentric circles in the cosmic microwave background, the echo of the Big Bang.

This, they say, is exactly what you’d expect if the universe were eternally cyclical. By that, they mean that each cycle ends with a big bang that starts the next cycle. In this model, the universe is a kind of cosmic Russian doll, with all previous universes contained within the current one.

Today, another group says they’ve found something else in the echo of the Big Bang. These guys start with a different model of the universe called eternal inflation. In this way of thinking, the universe we see is merely a bubble in a much larger cosmos. This cosmos is filled with other bubbles, all of which are other universes where the laws of physics may be dramatically different from ours.

These bubbles probably had a violent past, jostling together and leaving “cosmic bruises” where they touched. If so, these bruises ought to be visible today in the cosmic microwave background.

Now Stephen Feeney at University College London and a few pals say they’ve found tentative evidence of this bruising in the form of circular patterns in cosmic microwave background. In fact, they’ve found four bruises, implying that our universe must have smashed into other bubbles at least four times in the past.

Of course this still does not in any way confirm the idea that the souls of the deceased traverse these universes, or even persist as coherent consciousness. Or exist at all but it is interesting that we could be living in, rather than a singular universe, just a single universe among many. It is the sort of thing you read about in fiction, that is difficult to conceive of how we would ever truly know if such neighboring universes existed.

I feel certain that this will prompt a variety of believers from UFOs to ghosts to propose inter-universal visitors as the culprits of their particular topic of interest, but I see no reason to assume and less to believe that our universe is any easier to find as a place to visit, amongst the potential multitude, than our little planet is to find amongst the multitude of stars, and galaxies, and dimensions. If anything it makes it harder.
