The post 604 link is on orbital motion. I'm asking about the big bang.
The age of the universe is said to be 13.7 billion years. The size of the universe is said to be at least 90 billion light years across. The furthest visible object is some 13 billion light years from us making the visible universe 26 billion light years across (given the time lapse those distant objects have moved away).
So please explain this 'inflationary period' that alloys the universe to have expanded so much in so short a time.

Mathematical physics is gibbberish. That is your explanation 303. (There is the most probable reason of the universe at the end of the link)

First there was nothing, and then it exploded.

I'm not a physicist, but could it have anything to do with what we learned earlier - that space can expand at faster than the speed of light?

I'm not sure how you can conclude that I'm explaining mathematical physics to be gibberish? I asked for what I thought to be a simple explanation on the inflationary period. I've pointed out where my dilemma lies i.e. what I am not fathoming.
Here is a quote;

The goal of physics today is to develop this quantum theory of gravity so that we may one day understand what exactly happened around the moment of the big bang to get the universe started.
However, my question is about the 'period of inflation'. Has that been discovered through observation or has it been introduced into the theory to make the theory fit observations?
If the laws of nature were created in the big bang, there is no reason to believe those laws would be constant. Some of them could be gradually changing in their time and space, as that time and space gets farther from the big bang. That makes all the questions about the big bang more complicated. When using the laws of nature to explain what happened when, you have to take into account what the laws of nature were then.
First, if any of you think manygeese has smartness to contribute, you'd be wisest to just ignore the buffoon. He's an excellent case of dementia in the later stages. Till then, safely ignore the buffoon, and hope he leave the physics for us with functional brains and less jibjab.
I've been quiet here, mostly because pregnant wife make a busy life. I'm not a biology major, so I'm still learning the names of all the parts involved and all the fun stuff that goes along with that.
Now, onto the science.....
303guy, inflation is one of the toughest things to understand. We can blame Einsteins popularity in telling us nothing can exceed the speed of light. Inflation lasted only a tiny fraction of a second. The big thing people don't realize is that space is not matter or energy, so Einsteins statements don't apply to space. Therefore, space can expand as fast as it wants, beyond the speed of light. If space is lumpy and then smooths out and expands flat, suddenly, objects are able to move WITH space at whatever speed space decides to expand. Thus, inflation. If you could blow up a wrinkly balloon with dots on it, you'd watch the dots move away from each other even though the dots arent actually moving. Blow the balloon up fast enough, and the dots appear to move beyond the speed of light relative to each other. Dots are matter/energy, and the balloon is space. And that balloon just made inflation! It's really as simple as that. :-)
Inflation as a theory has been well established and considered proven by observations from WMAP looking at the cosmic microwave background and ever since by higher resolution maps from other sources.
Thanks Ben. Much obliged. Congratulations on your coming child.
So if spacetime expands and takes matter with it and then the expansion or inflation slows, the matter would then be left travelling through space? And perhaps even appear to accelerate?
Another question, is there any hint of where the actual centre of the universe may lie? Or at least in which direction it might lie?
