I am a dunce. Okay? That's that settled. Have no maths and little intelligence. Perhaps I can ask a question, though? Just throw it out if you like, delete it all. This is it: I've read that when you get down near the Planck length then physics breaks down. Is that right? But I would like to know what is actually going on in ' points' of space. So make it a question about what is going on in the smallest part of space that you can comment on, know something about. What I mean by 'what is going on?' refers mainly to energy I guess. There's nothing much else there is there? And why is it a puzzle? Well any point can be considered as being at the centre of a sphere, can't it? Out in space there, the whole of the universe surrounding any point. And EM radiation coming from every point on the 'surface' of that sphere. An infinite numbers of photons wouldn't it be? All crossing at this one point. And this is the norm. This is what is happening at every 'point' of reality. What does physics have to say about what's happening at such a point? Pages of maths won't do anything for me, they'll be unintelligible. But a bookload of abstruse maths can be condensed or summarised with such as 'this means time and space are relative'. So perhaps something similar can be done here. Or perhaps it needs the moderator to delete the whole thing?
