Is uranus biggest in our solar system

I've mentioned this to multiple people as being the flaw, but so many get up in arms that gravity is an accepted law and then do nothing but get angry. It's hubris to think we even understand the nature of matter and energy when we've barely glimpsed below the surface.

Seeing how extremely accurate the current theories of gravitation are in other contexts, I think it's probably natural to firstly try to find more localized explanations of the phenomena, at least.

That being said, though, Wikipedia also has a list of other seeming exceptions to gravity, which is interesting, to say the least.

My question is when are we going to need to move our particle accelerators to space so we can properly test things?

If MOND is correct, it doesn't seem that particle accelerators are the way to test for it, since its predicted effects occur at extremely low accelerations and energy scales; hardly what particle accelerators are good at.

I don't think it would be very surprising that we would need a different gravitational model to understand something like dark matter.

You have it the wrong way around, though. It is dark matter that is invented for the purpose of explaining other phenomena in terms of our current understanding of gravity -- it has been invented for the express purpose of not having to modify our theories of gravity.

Much in the same way we use different models of the atom for different things.

Those different models do produce consistent results, though. In other words, they are not intrinsically different; they're just different ways of saying the same thing.

Still means it can't go over 100% mass/energy in one area. So if there's 10% matter, 70% dark energy then there's also 20% dark matter.

I don't quite understand what you're trying to say with this. That's just true by definition -- x/x = 100%. Are you somehow equating percentages with absolute numbers?

What you asked me about in your first edit, is that we can take general relativities (in this case, % of matter/dark matter/dark energy distribution in our Universe) and use them when explaining (with presumably a big error margin) certain areas of said Universe. Dark energy is most common then.
This of course doesn't apply everywhere but we're talking theories here.

Dageir said that dark matter can overlay matter (just like it hypothetically surrounds Earth) which still doesn't take away from the matter that's being overlayed. It's tricky to explain but it's simple relativity - even though dark matter can make 150% of matter it can't make 100% of both matter and dark matter. So yeah, it's true by the simpliest definition but it can be kinda tricky to imagine if we're talking about distribution in a big area.

what the fuk is happening.
the question was just simple yet you turned it into a messed up math exam.
huehuehuehue

the "question" was unfunny and a ve-e-ery old joke, and an obvious bait, now it's a complex discussion boring to idle readers, not versed or interested in this kind of thing. I'd still prefer it over low-grade trauling.

Last time I looked into gravity the going theory was that dark matter doesn't exist but instead gravity is shared, or "flickers" between dimensions. Kind of like saying it's stronger than it seems when being observed. Or something. Which was interesting because they were saying that if the effect could be manipulated, it could be used to communicate with other dimensions.

I sometimes thing physicists must be on way more drugs than I am.

Edit: I'm not explaining this well. It was more like gravity from other dimensions has a subtle effect here or something.

According to my favourite ufologist and cryptozoologist, Dr. Franklin Ruehl, dark matter exists but is simply matter that hasn't been identified yet. This matter is what slows the universe in its expansion.

Maybe? I don't know.

This matter is what slows the universe in its expansion.

But according to math models, expansion is accelerating, not slowing, which is why 'dark matter' became a hypothesis on the matter.

Ain't it? Got to have the IQ of a cucumber to post in this thread.

I guess to rephrase it would be preventing the expansion from being greater than it could be
