Maybe those vibrating strings have a use after all.

 As far as I am aware, s channel scattering is a feature of Mandelstam/Bhabha scattering.   I found the maths involved here totally off-putting, so an idiot-level explanation of how s channel scattering relates to this topic would be much appreciated.

Correct on all points Sir.

A Big Bang must originate wherever one is, the proof of that is teleporting yourself to the origin of first light, then look back at the place you 'just left' :) It will now become your 'new' origin of 'first light'.

Is there a global setting for turning of those idiotic yellow half moons, once and for all?
Sorry, meant just moons, don't know why I thought of it as 'half moons'?
Poor eyesight?

Obviously your original dot has expanded, but has it spread across the balloon

Does the space between the galaxies  increase while the space inside the galaxies stays the same?

The galaxies are held together by gravity   ,aren't they?

Expansion doesn't take place internally to them ,does it???

That's my understanding, except that it is the galaxy groups that are becoming more distant from one another, rather than individual galaxies. 

Then one has to ask what effect the increase in distance between galaxy groups would have. 

As the distance increases, every group's gravitational influence on every other decreases.  Does the effective attraction between the members of a group increase?

Is that true, or is it just a question of scale? Relative to the size of the Universe, the expansion within an individual galaxy is very small...?

According to big bang folklore, space expanded with the events of the big bang, virtually, making each place in space as we know it a part of the big bang. Does that answer the question? It's a question based on a theory not proven, yet ideally the question is relevant to how we understand things such as the red shift effect and the cosmic microwave radiation.

Imagine the pre big-bang event as a golf ball, each dimple on the golf ball representing a region in space.......everything just got bigger with the big bang. Everywhere.

Is that what happened? That's another question, but it's the most accurate way to explain the proposed event.
