What evidence is there supporting the Big Bang theory?
In short, the universe is increasing. All of the galaxies we have observed that are great distance away are moving away from us. And the farther away they are, the faster they are moving away. It took small imagination to "rewind" that picture and see a time when all of the matter and energy of the universe was basically "in one place" and there was no universe. With all the energy (matter could not have exist as we know it in an energy field so intense) in that single place after arriving or being formed, a huge explosion, the Big Bang, formed space-time.
Hello, I''d like to ask, why do objects, that fall from higher heights hit stronger that those, falling from smaller heights, if force equals mass times acceleration, and yet accel

INSTANTANEOUS ACCELERATION: The acceleration of the body at any certain instant during its motion is called to be an instantaneous acceleration.
Electrical work: Electrical work is done if a quantity of charge (coulombs) is moved between two points which are at different electrical potentials. The SI unit of work
