As for morality, well that's all tied up with the question of consciousness.
From Roger Penrose
My own way of thinking is to ponder long and I hope deeply on problems and for a long time which I keep away for years and years and I never really let them go.
As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave and so on.
Some people take the view that we happen by accident. I think that there is something much deeper, of which we have very little inkling at the moment.
But I think it is a serious issue to wonder about the other platonic absolutes of say beauty and morality.
The idea is if you use those two shapes and try to colour the plane with them so the colours match, then the only way that you can do this is to produce a pattern which never repeats itself.
So what I'm saying is why don't we think about changing Schrodinger's equation at some level when masses become too big at the level that you might have to worry about Einstein's general relativity.
People think of these eureka moments and my feeling is that they tend to be little things, a little realisation and then a little realisation built on that.
And these little things may not seem like much but after a while they take you off on a direction where you may be a long way off from what other people have been thinking about.
Some people take the view that the universe is simply there, and it runs along - it's a bit as though it just sort of computes, and we happen by accident to find ourselves in this thing. I don't think that's a very fruitful or helpful way of looking at the universe.
