I'm not an astronomer, but I recognize a hack when I see one. Dark matter was a hack. Dark energy was a hack on a hack. Now they're hacking the hack to the hack
The article is about Dark Energy, not Dark Matter
However
Dark matter is not a hack.
It is just like viruses.
When they were discovered (1890s?), they were yet to be seen for decades.
The basic story is that a solution from infected tobacco leaves caused mottling on healthy tobacco leaves. Bacteria were suspected, but the scientists used very fine filters that excluded bacteria, and the leaves were still infected!
They called it virus from the Latin word for poison.
It was not seen, because they were smaller than the wavelength of visible light, and that was what optical microscopes use.
It was only in the 1930s when they were actually seen by electron microscopes.
So Dark Matter says we observe effects of something unseen through its gravity.
It may turn out to be a particle, or primordial black hole, or something else.
