So you think there are different processes which create multiverses? Why would you think that? You are adding unnecessary complexity.You don't know that, and no, nothing says that they couldn't have different laws and dimensions...If they were all created by the same process then they all have the same laws.Multiple universes are predicted by math. Nothing says that other universes don't have different laws, more dimensions...So waht, they move onto another experiment, that's what happens, sometimes the experiment works and sometimes it doesn't. What does all this have to do with possible other universes?It wasn't a failed experiment, but a mistake made in looking for gravitational waves. The galactic dust caused their readings to be incorrect. What the initial success and aftermath of BICEP2 (was not correct) showed was evolution's cosmic inflation proponents were wrong. They were all too eager to propose what you propose of having any number of different laws in other universes and that cosmic inflation backs up the Big Bang Theory. All it did was show where cosmic inflation is not found.. Even though gravitational waves were discovered after this experiment, it does not mean that the cosmic inflation theory part of the Big Bang Theory holds, too. It's like they're science-ing the sh*t out of gravitational waves so that the cosmic inflation model can be propped up.
And do you know why cosmic inflation is important? It helps explain the differences in our expanding universe. If it were not true, which it isn't, then our universe would look not as dense and similar as it expanded out from its initial "bang." It doesn't explain the clusters of our galaxies and stuff even if much of the materials in the mass can be pressed into a point of singularity. Moreover, as you know, the heat of the universe in one part of the universe being the same in other parts of the universe is what confirmed the BBT for these scientists.
"Another conundrum thrown up by the basic Big Bang theory is how to explain the relative homogeneity and evenness of the temperature of the cosmic microwave background radiation. How did large-scale structures such as galaxies and clusters of galaxies develop out of what should have been a rather boringly amorphous and featureless fireball?
This would appear to be in direct violation of the Second Law of Thermodynamics, which describes an inexorable tendency towards entropy and uniformity and away from patterns and structures. If our universe had started out completely smooth, then it should have continued that way, and the universe today would contain nothing more than thinly spread dark matter along with less than one atom per cubic metre of hydrogen and helium gas, with no sign of the texture and complexity we see around us (stars, galaxies, a multitude of elements, life)."
Cosmic Inflation - The Big Bang and the Big Crunch - The Physics of the Universe
What do you mean what this means for possible other universes? It means there isn't any evidence for them. First, it was established that one couldn't have an universe where our science experiments would not work. What was determined was in the core of scientists who believe in cosmic expansion, in order to explain how a "big bang" could expand in the way our universe is laid out, would accept all possible worlds. It was pointed out to them, just like I am pointing out to you now. We can't have worlds where our science does not work. Second, there isn't any experiment where to show how something, even of infinite density and temperature could expand in such a way that our universe ends up in the manner that it did. There is no evidence for cosmic expansion which these scientists keep looking for. They proposed a cosmology, but nothing backs it up. The other thing that we didn't even discuss is one can't have any point of infinite mass or temperature because the math doesn't work. To have any ginormous "infinite" anything -- density, mass, temperature, widgets, anything -- one is dividing by zero, 1000/0 = infinity. I learned only God can divide by zero. If we can divide by zero, then 5 x 0 = 5. In regular math, 10/5 = 2 or 2 x 5 = 10. Only a creator can create five items to make 5 x 0 = 5.
What's equally strange is you just ignore what I proposed of the possibility of multiple dimensions. Why do you continue to believe in multiverses where our science does not work and of infinite possible outcomes? Wouldn't God live in one of them if this were true ha ha? Mine is backed by scientific principles while yours is backed by faith in the "religion" of singularity and cosmic expansion.
You can't have worlds in this universe that work by different laws of this one, ok, but who knows what's beyond our universe or what might have existed before the BB.
