My friends and I have had an ongoing argument for the past week. We have been trying to argue if the universe is expanding or contracting in on itself? Also for further curiosity i wanted to know if it is expanding is it slowing down or speeding up? Also i wanted to know if anyone knew what cuased it. If it isnt expanding and its collapsing in on itself what is making it do this, or if its expanding now and going to collapse into itself later i would also like to know how that works. Sorry if i was confusing thankyou in advance.
