Is uranus biggest in our solar system

I think you people are forgetting about the dark matter.

Does anything dark matter?

Dark matter doesn't appear to exist in our part of the Galaxy (which is also an argument against its existance in the Universe) - or at least to be very abundant.
Additionally, it's not even confirmed to exist at all except for mathematical calculations.

Besides, if we considered hypothetical forms of matter/energy then dark energy would be the most common.

I'm pretty sure that if dark matter exists, it ought to fill the solar system as well, according to the galactic rotation anomaly. At least that's how I've understood it.

Is there anything you're not at least moderately well versed in, jeebus Loftar.

Though dark matter is by far the most accepted explanation of the rotation problem, other proposals have been offered with varying degrees of success. Of the possible alternatives, the most notable is Modified Newtonian Dynamics (MOND), which involves modifying the laws of gravity

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.

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

Now, back to the topic... Yes, Uranus is biggest. Jupiter accidentally slipped in one day and Uranus didn't even notice.

I am not physics man, but is not explanation of how does gravity works just that it does like magic? If so, this seems like area where we do not have perfect understanding.

[Burinn]

It was to my understanding that our current model of gravity works for what we currently need it for. Much in the same way we use different models of the atom for different things. I don't think it would be very surprising that we would need a different gravitational model to understand something like dark matter.

As I have understood it, dark matter does not interact with matter and might surround us completely.

It's supposed to be kg/area I think. It's not everywhere, there's just more places filled with it and the rest is dark energy/normal matter.
So yes, it'd be filling our Solar system too, to some extent.

As long as we don't observe it, we can't say much about it.

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.
