Since there seems to not be much in this area, here's a Q from me.

It has been asked why we assume there are no more than 4 forces. Could there be more?

I propose I am standing atop an atomic nucleus at a comparable size of 1/100 the nucleus radius. What do I see? Electrons buzzing around? Protons and neutrons underneath me? Maybe it doesn't matter what I see ... maybe only what I feel. Surely I feel the attraction of the nucleus holding me 'down'.

Do I feel anything from the passing electrons? I don't think I would. Maybe if I were sensitive enough I could feel a perbutation as one passed directly over me, but most likely nothing.

Would I feel my particular atom bouncing around as we 'vibrated' from our bound up energies? Probably slightly.

Here's where I'm thinking it would stop though. Would I notice an effect from the earths gravity? I don't think I would. I don't think it would even be as noticeable as the electron's.

Now ... would I feel the sun's gravity? I can't even feel it on earth, much less as this small size.

So if I haven't noticed it, why would I question that it exists?


I understand all of these are attractive forces, and that the last two are both gravity. I would only like to know if there may be a force acting at much larger scales that may only be felt by galaxies, or even an entire universe. It's proposed that the fundemental forces are one and the same, only different permutations at different energies and scales.

I question though that if all that we know are attractive and decrease in force with as scale becomes larger .... might there be one or more (weaker possibly, or even equivalent, to gravity) that exist at a much larger scale that have 'crossed' the threshold to become repulsive and not attractive that may explain the increasing speed of expansion to this universe? Possibly becoming evoked at the point the universe has reached a critical size? Or either we are reading the instruments worng.

Thanks.
