Facts are created from a bunch of people who agree upon a single opinion.

That is why people hate the "What if" scenario.

"What if" time is going faster due to the opinion of the universe expanding. Wouldn't that make carbon dating hard to measure?

People who are not open minded hate having their views questioned.

Of course in the end, you fuck with the person you played the "What if" game with and say: "Of course, it's all a matter of opinion."
