Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
We noticy it’s effects on baryonic matter, but have no known way of detecting dark matter itself. It’s a bit like how a fisherman can know that there is a large fish in the pond by the giant splashes and ripples in the water, but he can’t catch it because it has zero interest in any lures or bait he uses.
I thought we may have found dark matter already, but we lack the ability to measure it and confirm?

Now that there is an understandable analogy.
