I wonder what the final nail in the coffin will be for MOND. It seems like there’s new observations every few months supporting Lambda-CDM (even if it’s obviously not complete) over MOND. At some point, MOND is just a clever idea that was worth exploring and didn’t pan out.

Its a nice bit of tech. 73M in construction costs. The focal plane instrumentation alone weighs 10 tonnes. It includes 5,000 small computer controlled fiber positioners. The entire focal plane can be reconfigured for the next exposure in less than two minutes while the telescope slews to the next field. The DESI instrument is capable of taking 5,000 simultaneous spectra of different Galaxies

From this angle the telescope looks like a guy wearing a Vietnamese hat and doing yoga.

I’m amazed that we can detect a 10 m wide object at 4 million km away. Let alone track its trajectory.

Nobody tell Alan Davies.

when i read “hi-res images from The Sun”, this is not what i expected.

but this was better.

Dr Becky has a few different videos on MOND and what the current (video is from last year) scientific view of it is. Very informative, she’s awesome!
