All the different forms of energy can be traced back to the Big Bang.
Scientists believe that everything in the Universe was once packed into a tiny point. 13.8 billion years ago, the Big Bang was when this tiny point flew apart in a massive explosion, spreading matter and energy out in all directions and creating the Universe.
Matter is ‘stuff’, anything that has mass and takes up space. For example:
you
a ball
the air around you
the Earth, Moon and Sun.
Energy is the ability of matter to change or do something.
