Its also interesting,

That even if there have been infinite big bangs each one is still a Genesis..

To dream for a moment..could this be the creation of life (infinite like generating power for a light bulb)..that is never meant to stay here like the caterpillar that becomes the butterfly..

The Big bang would then be the Genesis of life for an infinite number of "higher" places..
This being a lower level..

All just for fun.

Regards
M. Gregg

Perhaps those periodic Big Bangs are merely the Heartbeat of God.

An interesting thought,

Remember time is relative to the viewer so like looking from some where else the events could be as you say not periodic as in long intervals just,

Boom, Boom, Boom, Boom>>infinity

Remember how long a year was when you were 2 or 3 years old and how quick it gets as you age..it seems relative to how long you have been alive. Or how close to the end..perhaps how a fly sees the world and how slow we seem to move to them.

Just for fun.

I do have a few things I find difficult to explain linked to metaphysical experiences..be that as it may..I do have more faith in a multiverse system than a mono universe system with a big bang.
I will have a look at the book you suggest..

I hope mankind will reach an understanding at some point that everything "Just is" and a profound insite. What ever that may be..

String theory doesn't really say anything about the number of potential universes. It does say something about extra curled up dimensions. Not the same thing. The multiverse thing goes back to some guy called Hugh Everett III, the father of the guy who is behind the band The Eels.

One problem with string theory is that to explain phenomenon A we have to pick just the right version of it. Unfortunately it will be incompatible with the version which does explain phenomenon B.
In the last 20 odd years it has not lead to any further insights and no advancement has been achieved at all.
It does however keep a lot of theoretical physicists in employment, all coming up with new versions explaining some facet or another and all completely incompatible with each other.
A sophisticated mathematical version of painting by numbers achieving absolutely nothing to further our understanding of the universe.

Quantum Gravity Theory is a lot more promising.

Default Deep Time

I always thought the concept of deep time was a difficult concept to get my head around......The idea that the BB was a "time" whereby everything was happening so very quickly....the age of Stars very brief, to be followed by expansion of the universe to the point where a single Atom occupied space of the same size of our currently known universe.
Think about this...our universe now is thought to be 14 Billion years or so....Nine zeros worth.......deep time has those zeros going way up....Nine, 90, 9000, 9 to the ????...........nth. The Big bang is essentially a firecracker going off, the light the age of stars..........the bits & pieces flying of into an infinity of distance......time then, has no meaning...as in no point of reference because nothing has happened for so very, very long.

Here is some relevant reading.

In essence manned space mission to Mars are currently impossible and traveling further is more or less unthinkable with what we know.

If we were able to reach speeds which would make distant space travel possible ie a significant fraction of the speed of light the travellers might be on their journey for about 10 or 20 years. But on their return they would find that hundreds of years will have passed for those who stayed behind on earth.

Something to ponder…

As I said there are an infinite number of string theories all based on the right equations saying anything you'd like them to, it is just a matter of picking the right one for your purpose.
What maths say does not really matter. My uncle, who has a PhD in Mathematics, explained it to me quite simply thus: Mathematics is the language of science. Only because it is possible to express something mathematically does not mean anything at all, the same way I can form the the grammatically correct sentence 'The mountain jumped over the tree' does in no way mean or even proof that mountains indeed jump over trees.
