    There's a very simple test of the general relativity law about the speed of gravity - and it has already failed it spectacularly.. Put simply if gravity moved at the speed of light then the gravitational fields of black holes should collapse in on themselves leaving them externally massless. If you take the simplest classical model of black hole with a central singularity then the inner event horizons require higher and higher escape velocities towards the centre and gravity must jump over the whole lot to escape from the edge. This requires A - an absolute frame for space ruling out a curved space time, and B sets a minimum speed for gravity which is close to FTL Simultaneous - ie nearly 'infinitely' fast.
    This model is not accepted in modern physics - but it is powerful and simple (orders of magnitude simpler than most others), and has no obvious point where it fails. (KISS - Keep It Simple Stupid - Occam's Razor) The real problem of course is that physicists are very stubborn and don't like their favoured solutions being contradicted - even in the face of direct evidence...

    Since work in Strong AI and have a pretty workable and complete theory I would say I do know a little about human intellect. The stuff about genetics vs nurture is very easy to answer. On the race question (comparable) intelligence is about 98% culture and 2 or less % genetics. One of the biggest factors in intelligence is the (cultural) expectation of being intelligent - when a small child, mostly its negative feedback telling children not to be intelligent. An even bigger factor is the random chaotic element which is inherent in all brain evolution and intellect.. Of course ultimately intellect is 100% genetics but then it is also basically 100% learning, both are needed, and one without the other is simply capacity that cannot be used.

    Genetically speaking though black people should be expected to have a very slightly lower 'average' intelligence than white because they have a wider spectrum of genetic variation. The same graph says that the most intelligent people in the world probably should be black not white - but most of these people are still culturally in places that hold them back as children or corrupt them in other ways. Black culture is what makes most black people stupid not the other way around, exactly the same with white people and every other race. Asian children are statistically better at mathematics because they have cultures that are more attuned to it.

    There is stuff in Strong AI that is too controversial for publication, but it is not about race - it is more that there are things that most people would be very unwilling to accept. - eg
    Most humans are not really intrinsically smarter than other animals, we just have much better memories and most of our superior intelligence really comes directly from remembered learning. We know this because all humans spent at least ~ 50,000 years with no writing, and no real cultural learning or sophisticated language - and basically did nothing intellectually that other apes and other higher animals were not capable of..
    Ironically humans totally conquered most of the world when we were no smarter than other monkeys - we hunted in larger groups which made us stronger than other predators, and were more determined and vicious than other predators. Our superior memories and better tool use also made us more ruthless and better killers.. Now that's the real human.

Fusion is currently slated as taking up to 50 years to come on stream, but if it was given proper funding and higher priority that could be reduced to ~ 20 years.

    Hydro storage on the scales needed also has enormous problems - very high build costs, the need for mountains to sacrifice, large areas of land, the need for vast amounts of water- which should be fresh water not salt.

    It doesn't matter whether there is a 'force' or a 'curved 4D world line' the result is the same - an exchange of energy. For black holes that exchange is across an FTL barrier. If the black hole has a central singularity and the event horizon is has an inner structure then the barrier is much higher than an FTL barrier.

    There is a quite simple test - if gravity transmitted energy at the speed of light then black holes should have no gravity field beyond the event horizon. In terms of the 4D tensor field the well (at the event horizon) is vertical and effectively infinitely long so the gravity field really shouldn't escape.

    In fact that FTL violation is a bit more serious for general relativity because it basically proves that gravity cant just be a curved 4D space time. If you do more research into the FTL region it is quite clear that general relativity fails completely at the speed of light - in exactly the same way that Newtonian theory fails at relativistic speeds. General relativity doesn't have a stable FTL geometry so it allows the universe as a whole to fold in and collapse in on itself -predicting a universe that either does not exist or is very young. To have a stable FTL geometry the universe needs an FTL Simultaneity - and once your there you have an FTL based physics, and then you need to rewrite general relativity to make it fit. All we need for that is to crush the time dimension to powder and restrict GR to quantum scales and then the two theories fit perfectly.

    The really strange thing is that physics has allowed general relativity to stand for 100 years - but then look at how anyone who dares to question it or criticise it is treated, they are jumped on and attacked as heretics.
