Yes, I am aware that gravity is by comparison the weakest of the 4 fundamental forces.
But it rules the universe! ok? ;)

By the way, is the existance of quarks proven or still a theory?

Proven. All six quarks have been seen in experiments with particle acclerators. The last one detected was the bottom quark at Fermilab in 1996.

Cool.

I would have to disagree.
Gravity is actually the weakest of all the forces.

The forces ranked from strongest to weakest

1. Stong Nuclear Force
2. Electromagnetic Force
3. Weak Nuclear force
4. Gravity

The strong nuclear force binds quarks together to form protons and neutrons. The electromagnetic force holds electrons in orbit around an atom's nucleus. The weak nuclear force is responsible for radioactive decay. Gravity also holds matter together, but it is so weak that its only noticible when large amounts of matter are involved. However all these forces play a part in creating and holding together the universe as we know it today and without one who knows how different the universe would be.

And to take it a step further, the Universe probably has some rotation about its centre of gravity, if the Big Bang theory is to be believed......

I believe the bing bang is a kid's bed time story.
But anyway, the definition of dwarf planet should clarify that it shouldn't be a satellite to another planet in the same system.
Because well, everything seems to be a satellite to something else in the universe. :p

Aaah, gotta love gravitational force. The true master of the universe.
Ok I need sleep.

By the way... the definition of dwarf planet:
A dwarf planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.

But, at a first glance I kind of disagreed with (d), because well, what is the exact definition of satellite?
I looked it up.

A satellite is any object that orbits another object (which is known as its primary). Satellites can be manmade or may be naturally occurring such as moons, comets, asteroids, planets, stars, and even galaxies. An example of a natural satellite is Earth's Moon.

All masses that are part of our solar system, including the Earth and Sun, are satellites of either a planet, the Sun, or the galactic center of the Milky Way.

So, ummm, I still don't agree with (d), because even galaxies move around an unknown center of gravity.

We can open the first extra-terrestrial hotel.
And if we don't have atmosphere... we'll presurize the whole place. And we'll recycle everything.

Diego, If it will be full of Life and no Atmosphere!

Hmmmm.......We will just have to throw a party to
to liven things up!..Get some real Atmosphere!

...and work out some way of retaining an atmosphere.

If they do that, can I come too??

Andy, Diego, we will just devide Ceres into 3. I will pay one of you
to cut the grass on the lawn on my bit!

I read that article and Ceres sounds like a little Gem of a plannet.
500 miles in diameter sounds just rite for me to build a small
Villa on.

Yes I plan to move to Ceres when I retire... in like 40 years.
They better hurry those construction plans.

It seems funny that they would include Ceres in with the dwarf planets. How big is the second-largest asteroid between Mars and Jupiter? Ceres is quite-a-bit smaller than Pluto or Eris. It seems like a funny place to draw the size line. What is it, 500 miles/805 km?

Its diameter is 930 Km and its mass represents 1/3 of the total mass in the asteroid belt. It's believed to contain more water than Earth itself.

It fills the gap between Mars and Jupiter, where the 5th planet should be according to the Titius-Bode law.

Subscript at the image of Ceres:
The Keck images have been turned into a 3D colour model

John Keck, perhaps? ;)

I wish...Hawaii sounds like a nice place to live.

Ceres is a dwarf planet now.

Last month, the asteroid was re-classified as a dwarf planet by the International Astronomical Union (IAU), and now new images of its surface reveal a surprisingly diverse surface terrain, scientists say
