All posible histories are realized. There is no escape, they have to face the lne of a cosmic beginning. Compared to the Bible, the Multiverse makes more sense scientifically.

Many Worlds in One: The Search for Other Universes

Parallel universes, also known as multiverse are a set of universes that comprise all of physical and quantum reality. I suppose that that is either an advantage or a flaw depending on your point of view.


The Idea of counting vacuas is not death, it was solved. July 4, at 5: Here is the link: July 5, at 5: If such a possibility is predicted by a theory that is viable in all other ways, then one should take it seriously as long as it can be tested. What other qualifications does he have to comment on the current state of particle theory? Charmingly and lucidly written, with intriguing historical asides that are little rests from the succession of astonishments.

The large maany of these vacua make any attempts to identify ones that worldx with the real world computationally completely intractable. Is ST getting like SA? The decay of the last false vacuum in any particular region of the multiverse results in a Big Bang releasing the vast amounts of energy in the form fundamental particles. People who talk about statistical calcuations of these vacua are just ignoring the fact that this idea has been tried, and now is dead.

The anthropic string folks surely have more than enough rope worldds hang themselves with. It posits solely from observation that we live between periods of accelerated expansion, just as Earth is the centre of the Universe.

It was at the time when Einstein had just developed his cosmological solution to the GR field equations and had introduced his cosmological constant to keep his model universe static. It does appear Steinahardt likes to get under some peoples skin.

Can we prove this? Surely energy and mass are conserved. Nov 26, Richard rated it liked it. The false vacuum, for instance, is a core concept, and Vilenkin just doesn’t seem to see that one could read this entire book, and its dozens of references to false vacuums false vacua? wrolds

Sean Carroll is credited with the following story: July 3, at 9: Hence, for cars to exist, the roads must possess very constrained, predictable features. I think Vilenkin exaggerates the entropy problem in these cyclic models, but surely there wasn’t room for him to totally explain his reasoning in this book, and it would have taken him far afield from hi Not the most wonderful book on cosmology I ever read, but it was good enough.
