Common Mythconceptions

Bulls aren't colorblind - cattle (and other ruminants like goats, deer, etc...) see blues, yellows, and greens yet all are kinda dimmed down. Best example I can think of is the colors you see at dusk and dawn - everything's kinda muted but you can still tell what the colors are.

I'm not sure I agree with the 'glass is a solid'. It's too much fun to think of it as a liquid.

Black holes - Not really 'holes' but hugely dense objects with massive gravitational pull.

This is a mythconception (ugh, I don't like that word either). We don't know if Gravity is a pull or a push. We deduce it's a pull because of our inability to jump off the earth. Gravity could just as easily be space pushing us to the ground. We don't yet know what space is either.

Glass is a solid in the sense that it holds its shape and pretty much acts as a solid. It isn't a crystal though, more of its own classification of material. The molecules that make up the glass aren't ordered like a crystal, but they are stuck in place unlike a liquid.

Anyone with more than a semester of materials should feel free to correct any mistakes in my explaination.

Force is a vector, so does the push/pull matter at all beside the direction the force is acting?

The graviton is thought to be the exchange particle for the gravity force. That's assuming gravity is a force similar to the weak, strong and electromagnetic forces, all of which have their own carriers. Gravitons, of course, have not been detected.

Another theory is that space exerts a push on particles relative to their mass. Is this a force? Is space the opposite of Dark Energy? Does space push things together while Dark Energy pushes things apart? Lots of questions for theoretical physicists.
