History of our Universe

Instant of the Big Bang.

Particles burst into existence. No one yet knows how this process takes place. From these particles will arise all the matter from which we and the universe around us are made. The matter and energy are so densely packed that 1 teaspoonful of space contains 100 million trillion trillion trillion pounds.   We don't know what the larger universe is like very far beyond this small chunk.

Scale of window: 1 inch across.

Weight in this volume: 10 billion trillion trillion trillion pounds.
