LOL! You've just described "Scientists'" great urge to believe in the fantasy of Dark Energy.
Dark energy, like dark matter before it, is a mathematical construct. Neither exists in the real world.
One great irony is that the self-same scientists who drink the Einsteinian Kool-Aid of "curved space" magically creating Gravity, are the same people who insist that there must be some sort of unknown "Force" accelerating our Universal Expansion.
Which is to say, when push comes to shove, proponents of the Theory of Relativity are the first people who toss ToR into the garbage bin when attempting to actually predict and understand the expansion of our Universe.
