It looks like they are using it for predicting the spectral results found in clouds. The ability to predict what the spectral lines should look like, especially with respect to the Lyman-Alpha Forest, should add both support and possible refinement to the model.This month's All About Space contains an interesting piece about Artificial Intelligence being used on the BB. It does not give an actual reference, but I have managed to find it:
Neural networks have made a breakthrough in modeling the Universe (universemagazine.com)
How does this fit the bullets?
(I don't know - I am just interested).
I wonder if there is an "official" position. But science, by definition, cannot go to places that are beyond any hope of falsification. If it is deemed impossible to test a t=0 event for the entire mass/energy of the universe, then it is metaphysics.However, I have recently been reading several books, which seem to state that the BB includes (division by zero) and the once accepted singularity. Have I been wrong in stating that BBT begins after the discredited singularity? I have referred to (t = 0) as much as possible (to avoid referring to a singularity. Perhaps I should check the dates on the books more carefully (they seemed otherwise OK) but I am pretty sure they were not all out of date (as much as any book is). What is your opinion of the official stance please?
I have the same misgivings about extrapolating the BBT back to extreme densities and temperatures, and especially to extremely fast expansions.Meanwhile, what do you think of #156?
Any 1/x^n will get you, eventually, to a zero. The tortoise always crosses the finish line because the time has an inverse effect on halfing the distance each time, so it's not a paradox.View: https://imgur.com/a/o3kgocO
Helio, as you know, any function divided into 1, gives a graph essentially based on the above. I chose this to avoid "mirror image" graphs such as those you get from 1/x or 1/x^2 et cetera. My point is that I see a "hare and tortoise" paradox here. It is my conjecture (pure metaphysical imagination, I admit) that there may be a function here which produces the t = 0 problem. Just look at the 1/e^x graph.
I'm unclear what your idea is here.Wouldn't it be fun to find that this backward extrapolation invokes an impossibility which disguises the "real" shape of the line at the smallest time values? And all these minute time intervals and soaring temperatures are the result of this unwarranted extrapolation.
Yes. And one doesn't need too go far in crunching those extended terms in a Taylor series to realize a finite answer is the result.For more complicated functions, think about their Taylor's Expansions as they approach zero.
Yes. F(x) = x alone does this, though exponents will get there quicker, of course.And, there are also cases where the limiting result is "infinity".
