The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.
cosmology
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
Contrary to what is often portrayed in popular presentations of the Big Bang, the event was NOT an explosion of dense matter into empty space. It wasn't an explosion of ANYTHING. It was an expansion of space itself -- and it was NOT expanding into anything. In other words, the expansion took place at all parts of our Universe at the same time. Our Earth is as much at the center of the Big Bang as every other point in our Universe.
The initial expansion of the universe was caused by the Big Bang's explosion of matter. Just as explosions here on earth cause expansion, so it was then. The math today, however, shows that the universe should be compressing again, as the energy lost over time would then be overridden by gravitational forces pulling everything back together. I'm sorry to say there's no such thing in our universe as anti-gravity, though. The universe's fate is generally accepted to be expansion forever at an ever slowing rate. To answer as to why this occurs, dark energy and dark matter are the forces at work - not anti-gravity.
The farther an object is from the earth, in any direction, the faster it is receding from us ... it looks just as if the earth is the center of the expansion. But wherever you are in the universe, that place would look to you as if it was the center of the expansion. The universe is already infinite, it has no boundary, but it's expanding. Are we confused yet ?
There would be no noticeable effect on daily life, or on the environment as humans perceive it. That's why it took so long to realize the expansion of the universe, and to develop the notion of the Big Bang.
Yes. Dark energy is responsible for the expansion of the universe.

Relativity theory establishes a speed limit for objects travelling through space - but the expansion of the universe is the expansion of space. There is no speed limit for that expansion.

The expansion in the number of conquered people did not affect Rome's expansion because it was the product of her expansion.
Increase in expansion affect the demand because more supply/expansion with constant demand will lead to excess in expansion which affect the demand.

No more than Earth's Sun, Earth's solar system, or the Milky Way galaxy. Movement is generally the cause of gravittaional influences or continuing expansion of the universe.
