Our Big Bang model universe is not symmetric in time. This doesn’t perhaps disturb you, but it disturbs physicists who think symmetry rules all. A new cosmology model, published in 2018, suggests that our Universe has a mirror image in the form of an “antiuniverse” that existed before the big bang.

We like symmetry
In the anti-universe, according to the idea of Boyle, Finn and Turok, time moves in the opposite direction of our universe, everything is made up of antimatter and is also mirrored with respect to us. This fulfills three important symmetry conditions that our universe without an anti-universe does not meet. This is called CPT symmetry. So, very attractive because we like symmetry. At the Big Bang, both universes arose at the same time and developed in opposite directions. But there’s more. The model explains the fact that we hardly seem to find antimatter in our universe. It also predicts the dark matter that we seem to find in our universe as a heavy variant of the neutrino and it also predicts the amount of dark matter we calculated. So it seems to agree with theory. Until now, I was not a big fan of dark matter as an explanation for the excessive rotational speeds of the stars in the periferies of their galaxies, the Electric Universe offers a better model there, but this might ‘convert’ me.
Finally, this hypothesis seems to offer a attractive confirmation of the idea that we experience time by increasing entropy. In the anti-universe, its entropy should grow in the opposite direction. From our perspective, the clocks in the anti-universe are running backwards and the people there are getting inexorably younger to end up being squeezed into their mothers’ wombs.
Where is it located?
The question remains, of course, where that anti-universe is located. But maybe that’s the wrong question. Dimensions like space and time are an experience, a product of the mind, the energetic changes in matter and of our memory.
Waiting for he Big Crunch
Ultimately, if the universe and the anti-universe stop expanding and gravity eventually wins, both universes could reunite at the so-called Big Crunch. Which would probably be followed by another Bang and Anti-Bang, time and anti-time, matter and anti-matter. So why worry?
Paul J. van Leeuwen graduated in applied physics in Delft TU in 1974. There was little attention to the significance of quantum physics for the view on reality at that time. However, much later in his life he discovered that there is an important and clear connection between quantum physics and consciousness.
What he learned between then and today resulted in a post academic course in quantum physics for non-physicists. A little bit later he decided to put the contents of that course, and more, in a book published in Dutch: Kwantumfysica, Informatie en Bewustzijn – and started a website on the subject. He translated the Dutch version of his book in English, titled: ‘Quantum Physics is NOT Weird’.
