All glaxies at the edge of our cosmos

Are going far from us at the phenomenal

Speed

The reason for this velocity is not known

To our recent physics

I as a layman assume the cause may be the pull from billions of other cosmos neighbours of our cosmos creating this pull

I assume that when you say "the edge of our cosmos" you mean the observable universe. There is no edge to the universe as a whole.

 

But you are basically correct. The most distant galaxies we can see are receding at more then the speed of light. The ones beyond that are (presumably) receding even faster.

It is very well understood. You might want to read up on the metric expansion of space or the big bang model.

This won't work. You can't have an equal pull in all directions from external mass. This was demonstrated by Isaac Newton in his shell theorem.

Seems to be some correction needed given some posts here: The speed at which the most furthest objects (quasars among them) are receding from us only approaches, does not exceed the speed of light. It's impossible is it not, as theorists/physicists understand, because when a massive object approaches the speed of light it takes on greater mass, and at the speed of light it becomes infinitely in mass; so while quasars can approach the speed of light they cannot attain it. Einstein's equation tells us that Mass accelerated to the speed of light becomes Energy. The speed of light is the tipping point where mass turns to energy and where energy at less than the speed of light turns to mass.

That is not true. For example:

 

 

We show that we can observe galaxies that have, and always have had, recession velocities greater than the speed of light.

The limit on things moving at the speed of light comes from special relativity and is, therefore, a "local" limit. The expansion of space is described by general relativity.

 

 

Einstein's equation tells us that Mass accelerated to the speed of light becomes Energy.

 

I don't think any of Einstein's equations say that.
