I don't believe humans will be around to see this, Twinkz but If you meant that no one knows when humans will come to an end, you're right. Our planet does have an expiration date, though. The ol' girl has about 5 billion years left, give or take.
I don't know enough about dark energy to comment on whether or not it exists but I can see where others would theorize that time would or could come to an end or freeze. This gives me something to read into, at the least.
