Interesting. I wonder how many people think they are night owls but aren't genetically night owls and are messing up their circadian rhythm through stuff like lack of exercise.

>How people wake up and regain alertness in the hours after sleep is related to how they are sleeping, eating, and exercising. Here, in a prospective longitudinal study of 833 twins and genetically unrelated adults, we demonstrate that how effectively an individual awakens in the hours following sleep is not associated with their genetics, but instead, four independent factors: sleep quantity/quality the night before, physical activity the day prior, a breakfast rich in carbohydrate, and a lower blood glucose response following breakfast.

I'm currently reading Warhammer books, and they are really interesting and actually there are some interesting ideas that teach me stuff. Kastrup's books are completely fiction just like the Warhammer books.

I just take issue when people try and classify Kastrup's stuff as philosophy rather than fiction.

I do worry about philosophy in general when it accepts people like Kastrup as a proper philosopher.

I struggle to understand how any intelligent person takes him seriously.

There are lots of different types of observations that dark matter explains.

Even if MOND perfectly explained the rotational speed in galaxies it couldn’t explain the other observations. So you still need dark matter.

> The most serious problem facing Milgrom's law is that it cannot eliminate the need for dark matter in all astrophysical systems: galaxy clusters show a residual mass discrepancy even when analyzed using MOND

The fact that some form of unseen mass must exist in these systems detracts from the adequacy of MOND as a solution to the missing mass problem, although the amount of extra mass required is a fifth that of a Newtonian analysis, and there is no requirement that the missing mass be non-baryonic.

I still don't understand. Doesn't this example then show that sure do your meta physics but don't every try and say that ideas apply to the real world of physics.

Aren't you saying, philosophers should keep their noses out of anything to do with the real world.

I'm happy either way, but when someone does some lsd and some metaphysics, they need to remember they are doing metaphysics which doesn't apply to reality.

The issue is when a philosopher does some metaphysics that doesn't' apply to reality and then for no reason thinks they have some deep insights into physics and reality.

edit: going back to the article it's like, I got this nice theory MOND from a philosophy point of view, it doesn't at all match up with reality and observations, maybe the whole idea of physics and reality is wrong.

I don't understand? Say we are talking about apples falling from a tree, we have the observations and theories around that. Why would I ever care about some philosophical idea about apples actually falling upwards because that theory is fun and challenging of philosophy?

When it comes to physics I only really care about reality, proper philosophy should help us understand that reality.

>We would very likely have made much more progress with physics by now if instead of trying to get the data to fit our scientific theory, instead working to create new theories to fit the observations.

The greatest criticism in physics is around the focus on String theory, which is is some kind of new theory trying to fit the observations.

We already have the core model which works for pretty much every experiment ever done to remarkable degrees of precision.

Surely science should be evidence based. Theories that are accepted are ones that match experiments and observations, rather than ones that are simply nice mathematically/philosophically?

I'm soo confused why they keep talking about the standard model in relation to gravity.

From wiki the standard model covers forces "excluding gravity in the universe".

Carroll uses the term core model to combine the standard model and GR.

In terms of detecting dark matter, isn't that in line with our predictions. If we predict there is very little dark matter in the solar system and that it would be extremely hard to detect, it seems like not detecting it is perfectly in line with predictions.

I don't know why they are framing this as a science vs philosophy thing. Dark Matter and MOND are both scientific theories.

I think the main issues is that MOND by itself simply doesn't explain everything we see. So last I herd was that the only feasible MOND theories left were "MOND + dark matter" theories. I wasn't even aware that there were any major theories that didn't include dark matter of some kind.

So since the article is based on science vs philosophy. The scientists are taking their view and position around the "core theory" simply because it does a good job at explaining observations, MOND by itself just doesn't mesh up with all the observations we have.

There are a couple genetic factors. One factor makes your pee smell really good, the second lets you smell it. So, some people can make their pee smell good, but can't smell it. Others can't make their pee smell good, but can smell others pee

I've never heard of it making pee smell bad though.

So we have decent evidence that exercise, diet and sleep can help prevent and treat depression. Some of that evidence is fairly strong causal evidence.

It also turns out that exercise, diet and sleep are correlated with brain volume. And we have good reason to think that's causal as well.

This just seems to support the idea that for a healthy brain you need to exercise, sleep and have a good diet. If you don't then there will be negative changes in the brain volume and you will get increase chances of mental disorders such as depression.

While we don't have enough evidence to completely demonstrate the causal link, I think this hypothesis is much better supported than alternatives such as smaller brain volumes being inherent and that's what causes people to not exercise and makes them depressed.

Finally studies show that exercise is just as effective as medicine.

Comfort foods are generally high fat & high carb.

I'm not sure how your comment is related to this study, or any study.

Studies show switching to healthier helps prevent and treat depression.
