News on the page of the European Space Agency mention a mission of a special importance for the future that is to be launched in pair of years. The purpose of the mission will be the detection of the gravitational waves that were first mentioned by Einstein in his theory of relativity. Connected to the theme, the nature of the black holes will also be the object of the investigation.

Yes, considering gravity is the weakest force, yet it affects us so much. k:

[Sean]

If gravity is the weakest force... which is the strongest and what does it affect?

[TaloN]

beer and the resulting urge to urinate.

Well, for some it is, but most wouldn't agree there

[Yobor]

The 'Strong Force' is the strongest force. It is a subatomic force that holds atoms together.

It's just an ordered playing together of different forces, like magnetical force. Planets circle around suns too, after all.

[Yobor]

Right. There are four know forces: Gravitational Force, Magnetic Force, Weak Force, and Strong Force.

I will not claim to be a physics professor, but sometimes google makes me sound like one :angel:

they're the weak and strong nuclear forces, and that's the electromagnetic force. the reason the nuclear ones don't overwhelm the universe is because they only act on scales smaller than the radius of the orbit of an electron, so only within the nuclei of atoms. the strong one stops the electromagnetic repulsion of the positively-charged protons from splitting up the nucleus, and the weak one controls the nuclear decay processes which are responsible for things like nuclear radiation (but isn't well understood). electromagnetic forces are both replusive and attractive, so they average out on a large scale, but gravity is always attractive, even between matter and antimatter (although in observed interactions between them electromagnetism is dominant since the scales are smaller) which is why we view it as being the dominant force on a macroscopic scale most of the time.

I'm not a physics professor either, but i know a bit about it

There are four forces, eletromagtic (that keeps molecules apart, incidentally), gravity, weak nuclear and strong nuclear (the strongest).
Who needs Google when you have the Guiness Book of Records?
