Many people often look up at the skies and do not understand that there is an entire universe above their eyes. The universe contains many objects, most of which are very large and massive for a human to comprehend. Even the vastness of the universe was not known The difference in scale between an elementary particle and the observable universe is around 10^40. Even brown dwarfs are many millions of times larger than a human. But the universe's exact nature is still unknown. Is it infinite? Or does it bend in a way that the nebulae and galaxies that seem billions of light years away are in fact very near to our own?

The universe is a very large place, with objects like brown dwarfs being millions of times larger than humans, and its exact nature remains unknown.
