Multiverse 2--Cosmological Constant Necessitates Multiverse

[Rizzy55]

Blue juice Brian greene..you'd be eating your own poop if everything happened. Its funny how they dont see how absurd this is and just consider reasonable alternates. Did you know the odds are greater that Shakespeare would be written in the stars than human consciousness? Thats where multiverse leads.

The odds dont change either. The odds of life here in this universe are still zero--the other verses dont affect that.

It doesnt matter how many lottery tickets are sold. Your odds are the same.

Well, within the first 30 seconds of the video, you got the entire idea of probability and the existences of universes wrong...from both a quantum mechanical view and a mathematical view. Only an idiot would be able to achieve such idiocy.

[Battery9876]

Maybe there's an explanation to the cosmological constant. Some phenomena appear extremely improbable until they are explained. TAke the fact that the universe is flat for instance. The problability is extremely small - don't know how it compares to 10e-140 - , but the theory of inflation explains it in a simple way.

This being said, I believe in the multiverse theory.

hey dude i have nothing against you kid but i beleive in the multiverse theory.

[gallileotheguineapig]

There's an intresting article in Scientific American:Life in the Multiverse,where there could be universes with different physical laws that could sustain complex life

i disagree with how you are describing the multiverse. I think it is possible to have something like a multiverse, but they would have to be identical. quantum physics is based largely off of the particle-wave duality of matter, basically, everything that exists is BOTH a particle and a wave at the same time. and since a true wave has no end, and physics does not deal with dichotomous extremes, there must by definition be an infinite number of the same partical on each wave so that, if divided

[chris11sholtz]

equals one. (infinity/infinity=1) anything less than an infinite amount of particles (each extra partical would be a part of another universe) would, when divided, equal an infinitely small number, which as i said, physics cannot describe, therefore it cannot exist inside a universe.

I'm still struggling to grasp the logic behind the assertion of a multiverse. Why doesn't the anthropic principle apply here?

[PostmodernAnomaly]

I don't know, the theory of relativity isn't false simply because a human discovered it. So, I suppose in the same manner we are talking about potentials understood in a limited way.

The anthropic principle does apply: we only have a limited understanding of it. But perhaps the anthropic principle needs to be expanded? We don't simpy project, we discover and seek. So, I suppose, the universe projects back to us.

1 in 10 to the POSITIVE 120th power.

[keggerous]

infinite everything if it were true. to bad its prob not true and is impossible to prove it to be true. string theory is hanging on by just that a string! it hasnt had any luck with the higgs or any predictions. anytime it gets something wrong they just rewrite the math and say its still viable.

[ThoughtfulAtheist]

my main objection with this line of thinking is exactly what is said in the video...it requires a leap of faith. Its too big a leap for me. Plus then don't we still have to answer, "what caused the multiverse"? I dont think it helps our position any. So why should we adopt it?

[PostmodernAnomaly]

What about the cosmological constant and how inredibly unlikely it is? Doesn't multiverse provide an explanation for it?

[ThoughtfulAtheist]

No i dont think it really gives any sort of practical answer to that problem. Doesnt there have to be a primary timeline of which we are a part? If new universes are spawning at every possible moment in which something different could have happened, unless this happens in every universe (in which case i think this theory loses all practicality), implies that our universe is the primary one from which the others spawn. Where is the evidence for this?

[PostmodernAnomaly]

Put in Michio Kaku in search engine. He talks about it all the time. He claims that unvierses are constantly being made. Our universe is one among many.

Now, one can ask "Where, where does the multiverse come from?"

Well, we asked where does the universe come from and maybe found our answer. The problem with answering questions is it leads to new questions.

[gothatfunk]

i wonder how many alternate universes humans are already extinct in?

[PostmodernAnomaly]

Haha, good question. As I said before, multiverse both ensures our destruction and our survival. One might be good enough for us to actually play around with space-time and whatever. I love this stuff.

[ThoughtfulAtheist]

I wonder how many alternate universes exist in which humanity never existed in the first place.

[PostmodernAnomaly]

A lot, they're saying.
