For years, scientists relied on calculations based on the Big Bang theory to determine the early universe’s expansion rate. More recent observations, however, on how fast the universe is actually expanding, don’t seem to fit within the accepted model.
What’s causing the discrepancy? Scientists have no idea. As Phys.org explains, there are plenty of theories, “but the true explanation is still a mystery.”
What they do know is that there must be a reason for the differing measurements. According to one scientist quoted at CNN, “This mismatch … is really impossible to dismiss as a fluke. This disparity could not plausibly occur just by chance.”
Of course, the irony here is that so many scientists consider the very origin of the universe to be itself the result of something that could be called “chance.”
Science demands a reason for whatever it encounters. But it’s far from able to explain all the mysteries of the universe. And one reason for science’s limitations is the self-limiting worldview it so often operates from.
