Has anyone considered that the universe goes through expansion and contraction phases? I have no idea how long these trends would be, but right now it is of course expanding. To take that direction and extend it back to a big bang point of singularity, is like looking at the global warming hype and extending that to say the earth will eventually erupt into a fireball.
Well we are now heading into a cooling trend.

I can promote this if you make two fixes.
First, explain why you believe the universe might begin contracting at some point.
Second, don't use any unrelated controversial topics for explanatory assistance, meaning that references to global warming have to go.
Please post a note when you're done.

I really don't have any reason other than comparing it with seemingly unrelated cycles. I was just asking the question, but can do some independent searching first.

I asked why you believe the universe might begin contracting at some point because one way this might be possible is the topic of a thread opened just a week or so ago, check out Dark energy without dark energy.
