Exactly!

Science has already told us that space itself is accelerating in all directions faster than the speed of light; the universe is expanding. But where is it expanding to?

If the universe is expanding into infinity, it will expand and accelerate forever, hence, gravity. Although gravity feels like an attractive force [as if we were being pulled toward the center of the earth], it is actually a repulsive force [we are actually being pushed away from the earth]. We cannot feel that centrifugal force just as we cannot feel ourselves spin on the planet earth, nor the earth whirl around the sun, nor the solar system whip around the galaxy, nor…you get the point.

The reason no one has devised the Grand Unified Theory, the Theory of Everything, is not because of a failure of physics, but a failure of imagination.
