* WIMPs: weakly interacting massive particles
* MACHOs: massive compact halo objects
* RAMBOs: robust associations of massive baryonic objects
There's also the HERO (hyper extremely red object), which isn't quite dark, but close.
It is the most mind blowing thing that could actually be built someday by humans imho, well if we decide to stop blowing all our budget on killing other people

...and a paper:
They're great with names haha.
"The ESO specialists expect resolutions from OWL that are up to 40 times higher than those of the Hubble Space Telescope. If the 100-meter mirror cannot be financed, a 60-meter variant is being planned. The name OWL would remain the same. Because then the project is jokingly called »Once was larger«."

Can we propose the Obnoxiously Large Telescope to replace it?
The rest of the scientific community...notsomuch.
