As someone who is currently studying dark matter, MOND is currently disfavored in the field of cosmology. It does not as simply or effectively describe galaxies closer to home, or observations of the cosmic microwave background. These galaxies pose a challenge to lambda-CDM, but that does not prove MOND correct.

As someone who checked it out for physics here's my experience:

Anything that could easily be found and be correct that would be found on chegg, would be easily repeated by chatgpt, and with usually clearer solutions that was easier for slightly different problem prompts.

Anything that could not be well answered by chatgpt likely would not have a good solution on chegg, being either outright wrong, or extremely confusing as an answer.

My interpretation is that synthehol isn't supposed to be a copy of alcohol, it's designed to give the positive effects of alcohol without the downsides, so that taste is likely not the main consideration.

More like Sony doesn't want to cannibalize selling their own dedicated Blu-ray players for a much higher profit margin.

A $100 bluray drive, an Ugoos am6, and coreelec can get play everything for way less than a high end bluray player that can cost $1000.

Shame it doesn't support dolby vision though.

Transporting food halfway across the world ain't free either.

Not in one exposure. Human eyes are much better with dealing with extremely high contrasts.

Cameras can be much more sensitive, but at the cost of overexposing brighter regions in an image.

While pork and poultry are not great for the environment either, they have nothing on the methane emissions of ruminating animals like cows.

I can't control the infrastructure that requires me to drive a car.

The original question was why solar systems and galaxies are in planes, and your explanation is wrong.

What do you even mean by similar orbits? Most orbits are circular for a totally different reason, and that is tidal interactions.

I hate to be that guy, but this is wrong.

The solar system is mostly in one plane because it formed from a cloud of gas. The cloud of a gas has some total non zero rotation and as the cloud collapses interactions flatten the cloud into a disk, where all of the planets formed.

This same principle applies to galaxies.

Except that cars are heavy, so multi-level parking is prohibitively expensive.
