Did the Big Bang really happen?

#1

Post by OleCuss » Tue Jan 21, 2020 11:55 am

I enjoyed this article: https://www.bbc.com/future/article/2020 ... has-no-end

I don't know which scenario is correct (or if any of them are) but I am very uncomfortable with what I consider to be the sort of magical concept of the Big Bang Theory as typically portrayed. It is nice to see people working on alternative concepts.

I'm not sure we'll ever know enough to get totally away from invoking something which seems magical or semi-magical but it is nice to see people working on it.

I'm a fan of an alternative to General Relativity, Einstein Cartan Sciama Kibble gravity or ECSK that isn't mentioned.

It has a natural Big Bounce so inflation is not needed. Its Black Holes have no ugly singularities. Thanks for the link!

Inflation has always seemed like a kludge to me. Need inflation? Add an "inflaton" field. Reeks of epicycles to me.
If you don't understand your noise, you cannot reliably extract a meaningful signal.

The inflaton field also implies an inflaton particle. Unlike dark matter, for which there are currently measured effects at least and also candidates that are motivated be known problems in physics like the strong CP problem (axions) and the workability of SUSY, the inflaton is a one trick pony,

Folks have tried to pass off the Higgs boson as an axion https://en.wikipedia.org/wiki/Inflaton but this is not widely accepted.

Sorry, garbled. Folks have tried to pass the Higgs off as the instanton.

Actually it’s wrong. This “finding” is a mistake and has been debunked.

I'm home with more than my phone now.

When you look at the uncertainties in the age determination there is no significance that can be assigned any statement that its older than the universe.
