16 February 2018, 5:00 am

For a while, some physicists worked on a theory unifying the other forces with both the force of gravity and the film

Wonder how it is that Magnetism is classed as a Weak Force when the entire Earth is a giant Magnet? (North & South Poles). Hmm...
Perhaps it was just for Comic effect and not Cosmic effect! :2funny:
In the world of AI, it's the thought that counts!

It's only weak by comparison. The Strong Force is what holds elementary particles together, IIRC.

Also, any force can be powerful if you have it in sufficient quantity. The relative strength/weakness of the forces expresses how much generating matter you need to get a given effect. Or something like that.

I thought gravity was a weak force - easily demonstrated by a magnet 'beating' it.

But yes I seem to recall that about particles being strong forces. Long while since I did Physics...
