What is "Mind?"

The assumption that everything MUST happen would be true if there were an infinite number of universes

The idea is that the most probable histories of the universe would be like the surfaces of the bubbles. Many small bubbles would appear, and then disappear again. These would correspond to mini universes that would expand but would collapse again while still of microscopic size. They are possible alternative universes but they are not of much interest since they do not last long enough to develop galaxies and stars, let alone intelligent life. A few of the little bubbles, however, grow to a certain size at which they are safe from recollapse. They will continue to expand at an ever increasing rate, and will form the bubbles we see. They will correspond to universes that would start off expanding at an ever increasing rate. This is called inflation, like the way prices go up every year.

The probability for a state of the universe at the present time is given by adding up the amplitudes for all the histories that end with that state.

I've been using this 3 billion years ago, nothing much existed with respect to mind and vision and such, and I suddenly realized that I could probably safely move up that number to closer to 560 million years ago

But consider that it may have taken two and a half billion years for single-celled life to have developed molecular communication to the point where multi-cellular life was possible. Compared to that, the development of mind may have been a walk in the park

Do they allow wooists to conduct experiments in the particle accelerator?

This technology will be used on humans. Why some of you dismiss this is beyond me. If you had Huntington's disease in your family, wouldn't you pay to have it permanently removed from your progeny?

but in what way does scale affect/determine or become otherwise important relative to the significance of humanity and mind/consciousness?

I mean its incredible that all that vast space fits in your head. Don't you think?

I would offer this. It is an explanation of the world that is a natural extension of what you experience everyday and what you imagine your fellow humans to be experiencing everyday. There is no jumping off point required to crazy mental constructs that only few individuals understand (madbolter1 is the type example in my book of this one) or to religious ideas involving the supernatural. No.

If you are saying that all of space fits in your head, then yes, that is incredible.

What is a mind that it can do such a thing.

If it is comprehensible by the mind then it "fits" in your head and that is an amazing and mysterious thing. It mediates the whole notion of scale in relation to the human observer. What is a mind that it can do such a thing.

I would agree that, given its structure, in this universe there are things that cannot happen. However all things that can happen within the structure of the "laws" of physics will, including life. And in that sense life was /is inevitable along with consciousness. And that's a fascinating and mysterious thing to contemplate.

the technology to transmit radio emissions

Anyone can run this equation with a high school education:

I find many of your statements to be amazing and mysterious. You could substitute ant observer for human observer and the above would still apply, though you could demur that the ant cannot fit all of space inside its head.
