Hello. I wonder what you think about the following: About 13.7 billion years ago, there probably was a Big Bang. The astronomers start their counting of time from that. What do the philosophers think of what happened before the Big Bang? JB from Sweden

Astronomers routinely observe the most distant objects and the earliest events in the universe. If we had a telescope powerful enough, could we observe the Big Bang and if so, could it be observed whichever way we looked?

Why does the Universe need to have a beginning (or an end)? I am trying to understand why so many scientists believe in the Big Bang theory and why more people don't believe that the Universe has just always existed.
