A Trip Through The Universe
– “For You To Enjoy And Share With Friends” –
Another trip through the Universe travelling at the speed of light. Again it gives you the perspective of actually tiy we are and how vast the Universe actually is.
The Milky Way is a huge city of stars, so big that even at the speed of light, it would take 100,000 years to travel across it. Beyond our own galaxy lies a vast expanse of galaxies. The deeper we see into space, the more galaxies we discover. There are billions of galaxies, the most distant of which are so far away that the light arriving from them on Earth today set out from the galaxies billions of years ago. So we see them not as they are today, but as they looked long before there was any life on Earth. So how big is the universe? No one knows if the universe is infinitely large, or even if ours is the only universe that exists. And other parts of the universe, very far away, might be quite different from the universe closer to home.
