The Infinite Universe

The universe is likely to be both infinitely large and infinitely complex. With our feeble, limited senses we can observe only a very small part of the universe around us. That's because evolution has given us the senses we need to survive here on Earth. Science can try to study and understand the physical world but it is doubtful we can ever know much about it. Although it is nice to understand how and why things work, it is not necessary to have an explanation for everything.
