it was explained to me by linda susskind and i thought it was a very beautiful idea. and i was quite taken by us. but when i learnt it had to have a space time that was 26. i mentioned, i said okay, know when they got down to 10 dimensions. so no, that's wrong. it has 4 dimensions, one time through space. and if you tie up the other ones into a little ball because too small to see, that doesn't help. it's not, doesn't work very well. i don't think it works. so i form the idea quite early that that theory is not correct. whereas quantum theory is certainly correct to a large level it's, it's lost, it's, it may not be completely correct. but at one end of the scale, it is very, very close to be correct. you have to say, what is it that makes it not quite correct? where that is where gravity comes in. so what i say is the union between general relativity economy mechanics is not that you bring the machinery of quantum mechanics to bring it into the fold of cause it can, you know, it's an even handed marriage that has to be give on one side and on the other side, sure, i'
