The image formed is called a virtual image, and is actually located behind the mirror. This diagram explains it pretty well http://upload.wikimedia.org/wikibooks/en/8/8b/Virtual_image.gif" The rays in reality come from the actual object being reflected, and it is as though the brain is...

As I understand things, the following are true: The further away in space we observe, the further back in time we are looking The further away in space we look, the faster galaxies are receding from us If these are true, doesn't it indicate that the rate of expansion of the universe...

OK, I like the idea of a small percentage change making a significant difference from a once balanced system, so thanks for that, maverick. I can see how the angle I was looking from was seductive but flawed though I was evangelical about it earlier! I'm now reading up on hamiltonians but...

Agreed. So under conditions like this, gravity is stronger than anything else known. If super dense matter like this were the norm rather than the exception then we wouldn't exist, but if we did we would be saying how strong gravity is. I fully accept the points you make, but the relative...

OK so I think I'm starting to get it. The gravitational field strength of a proton is significantly weaker than it's electric field strength. That makes sense. But to blandly say 'gravity is weaker than any other fundamental force' is not correct. We just need to clarify the terms of our...

I have read through countless discussions, and have still to be convinced that gravity is weaker than the other fundamental forces, even though this is the accepted wisdom. My argument is that it is mass which dictates gravitational attraction, whereas charge, for example, is responsible for...
