#681959 — Question for EXPERTS on BANGS < >BIG or small< >

we 'know' the Big Bang started 13.7 Billion years ago,
(+/- whatever), but my question is:-

                 When did the "Big Bang" stop ?







Note that if the Big Bang has not stopped it would need feeding,
and at an ever increasing rate,to feed a sphere of ever linearly 
increasing radius.

But if, on the other hand, it has stopped then, as any expert on 
explosions will tell you, it would proceed NOT as an ever increasing 
sphere, but rather as an ever increasing shell of thickness equal to:

     Speed of transmission times of explosion * (Tstop - Tstart)

and there is no sign of that in the universe we inhabit, whatever finite 
value you choose for Tstop.

The question makes no sense.

The big bang is a SINGULARITY. It did not "occur in time", but rather is
in essence a boundary of the manifold in which time progresses. One can
trace worldlines backwards to limit points of the big bang, but not to
the singularity itself (which is not part of the manifold, and such
tracing can only be performed in the manifold).

So time-related concepts like "start" and "stop" simply do not apply to
the big bang (they inherently refer to the manifold, which does not
include the singularity).

The big bang is NOT an "explosion". It is a SINGULARITY. It has no 
"location"; speaking loosely, the big bang happened everywhere.

Is there any sense in saying the Big Bang occurred 13.7 billions years 
ago, Mr Roberts?

Well I'm sure i've heard it described as "an explosion of space and 
time", but i would agree that is twaddle eh!

  It is a SINGULARITY. It has no

But did it also happen for all time Mr.Roberts?

Yes. Because that is a measurement in the manifold with which we model the universe.

I'm sure you have heard LOTS of nonsense. That does not make it correct.

No. As I said before, "time" does not apply to the big bang itself. But the 
proper time of geodesics is well defined, from their limit point (approaching 
the singularity) to today.

Some nice sensible answers, Tom!!!

This is something to pay attention to, Keith. Physics is
complex, and descriptions of theory can sometimes be imprecise.
Only the measurements and mathematics get to the core of
what physics is about.

Enjoy,

That is *one* definition (in which the term is written “Big Bang” instead).
