What if there is no ultimate beginning or end?
Before I state an explanation I would like to say I am not very knowledgeable in the on going pursuit of science and evolution, however I am always eager to learn. Recently I have been exposed to the minds of Dr. Neil Tyson, Richard Dawkins, and Carl Sagan. I am new to the community and listening to even footage from the 1970s I have gathered as many ideas as possible and I am just extremely interested on many subjects.
Now, my explanation is what if there is no beginning or end? Not in a religious matter but humans can only perceive a beginning and an end because we are born, live and die. Things on a microscopic and even of a giant level in the cosmos are created, live and die. What if the universe as a whole is just an infinite loop of events, such as the big bang and crunch? I have done some research and haven't found any suggestion on the topic, I feel its a valid enough idea to have whether it can be true or not. I am just curious on the thoughts, thanks for any input.
