Is Our Cosmos Recycled?
There’s a great article at New Scientist on speculation that the cosmos existed before the Big Bang and that the bang itself was a recycling effect. It seems that scientists are now starting to play with computer simulations to try and determine what a pre-Big Bang cosmos looked like:
Did our cosmos exist before the big bang?
“If the universe we inhabit emerged from a previous cosmos, can we know something about the universe that preceded ours? LQC simulations show that it too would have had stars and galaxies. But opinions differ when it comes to the quantum phase just before and after the big bounce, when it is impossible to pin down the volume of the universe due to quantum fluctuations.”
