A New Cosmic Tension: The Universe Might Be Too Thin

Has dark matter and dark energy actually been found or is it still just something that makes theoretical sense?  In other words, did Hudson have the right to make such a certain statement?  My apologies for my ignorance but my science knowledge is way behind.

I'm not aware of any actual detection/observation of these things. Certainly there are experiments set up in the hope of detecting dark matter, but I don't think they found anything, certainly not anything conclusive or unambiguous.

I continue to consider these things as a mere patch to try to mend a broken mathematical model.
