I thought this might be interesting to some people,

Its not a topic of discussion for me.
Its slow at first but stick with it and its quite interesting.
It reminds me of the Christmas lectures on science topics.

Great video. One of my favourite topics of interest though no hope of understanding it. I appreciate how these guys are standing on the shoulders of those smart cookies before them such as Faraday and extending or re-writing the known physics. it's good they take the effort to explain it in layman terms.

Its interesting to note that in years gone by black and white TV days Quatermass and the pit series (which I prefer to the films) the quote was "it can't be, mass into energy". They talked about it then but we thought Einstein's E=MC2 was to difficult to even contemplate.
But these days when you realise its just E=Energy, M=Mass and C2 is just the speed of light (Energy=Mass) its quite interesting.

If you like old B/white the series is on BBC Iplayer for the next month..the special effects are pants but I like the story.

Infinity:

Its not until I found out that you can have different infinities that it made me stop and think:
Quote: an infinity of sheep is not an infinity of cows.

The other thing that stopped me in my tracks was that "nothing is a paradox".
ie nothing in theoretical terms is (no-thing) no energy no dimensions no existence.

Here is another you might like:

I like the idea that "nature's laws must be beautiful". Great video. I enjoyed the series Brian Cox recently did on the Universe shown on TV. The concept of infinity and imaginary numbers was too much for my brain to deal with at school. Didn't do any serious maths after that.

Hi,

Yes the concept of infinity is a problem.
I spent some time thinking about it after watching a few videos.

This is the problem I have with it:
Does infinity exist at all?
Well from a purely physical point of view if you look at an onion cut in half, there are layers. At the end of the layers there must either be another layer or an infinity. If you look at the universe in the same way there has to be infinity or there would be another "layer". If that was a multiverse then that would either be infinity or the multiverse would be in an infinity.
If there was no infinity then what? the universe has to be somewhere and I don't see how something can exist within nothing.
Ie no-thing is a paradox no energy no dimensions no existence. So even 0 can't exist because its a quantity.
Its a bit of a PITA really :D
If the universe exists in nothing then in theory it doesn't exist.
In Zen quote: There is, only what there is, there is nothing more.
It takes time to "assimilate" the idea its very strange.

If you like strange things and familiar with the double slit experiment:

I guess you have come across entanglement if not then the previous link will make no sense:

I have thought about the Quantum Eraser,

It just occurred to me that if the human brain is acting like the three detectors in the experiment.
If it was working like detector 1 is that premonition?
Or is it proving that premonition can happen?
:D in the experiment it looks like its millionths of a second apart but is the time restrictive taking into account the light travelling billions of years from a distant star. LMAO is a brain just a quantum detector and the universe acting like the internet with AI.
Anyway I thought the video was interesting.

I got lost when one of the videos suggests we are just energy fields. Maybe we are version x of an AI making incremental progress of understanding and building version x+1. The movie Ex-Machina was quite good in a naive way. Then that didn't sound right for us as DIYers trying to petulantly give valves/tubes more life when perhaps transistors should be made to sound like tubes. Wonder if AI would be nostalgic like that.

I hate to say it,

but there was a time when terminator looked very Sci-Fi but after seeing this its going to happen there is no doubt about it:
https://www.youtube.com/watch?v=LikxFZZO2sk

So the mechanical side is well on its way and with quantum computers a reality I think AI is going to happen as well.

From the point of view of we are energy fields its a fact, we are energy observing energy around us.
Everything is a construct although I hate to think along the lines of the matrix.
The question seems to be is energy alive or what makes it become alive.
From E=mc2 there is only energy nothing else exists, or so it seems.

There are other ideas like "emergence theory" which is interesting to think about. Its a case of looking at ideas and see what you think might be correct or have merit.
https://www.youtube.com/watch?v=Qa4JkgKDaR0

Just for interest linked to Ex-Machina there is already a term used to describe when AI becomes self aware its called the "AI singularity".
If your interested in AI dangers look up Slaugherbots on youtube I could put a link but its not really a topic for discussion.
Another worth a look is Sofia:
https://youtu.be/Bg_tJvCA8zw?t=171
Things have moved on since this was shown.
There was talk a while ago about the 3 laws Asimov:
https://en.wikipedia.org/wiki/Three_Laws_of_Robotics

The third law discussion was for robots to "learn" Combat Sambo and judo to protect against other robots.
Read into that what you will.

Interesting discussion. Having a science and engineering background, a never ending thirst for knowledge and an avid reader (about a book a week usually) most of the concepts don't bother me. I follow numerous science related media. There is one concept however that I can't wrap my head around. It is Quantum entanglement. It just just seems wrong and while aspects of it have been shown to exist it boggles my mind. Open vs closed universe, multiple dimensions, strings, dark matter and energy, AI, etc I can envision. However most have no bearing on my audio designs. 8-)

Good listening
Bruce

Hi Bruce,

Its just a thought but if particles or perhaps energy waves can become entangled, then in theory is the whole universe entangled from creation at the "big Bang" (I am not convinced it was creation "the start") could it be that No-thing is linked to if you are not entangled in it you cannot perceive it? ie anything other than the universe would not exist as far as the contents of the universe are concerned. At that level the universe would be part of something that is entangled at a higher dimension which would be an infinity of entanglement. Anything that happened at that level would have immediate effect on the universe as we know it.
NB that the entangled particles are normally in the opposite state like Anti-matter, but with the idea of Qubits infinite states in infinite entanglement.
A bit nuts but interesting.
If this was the case then entanglement is what we perceive as reality. A dream is only seen by the dreamer.

Something I find interesting is that "they" say the Big Bang expanded so fast that is seemed to break the speed of light.
But if the Big Bang was an entanglement creation event then information speed isn't restricted by the speed of light (or so it seems)
Which would make more sense of chaos theory and the butterfly effect. :D (everything effecting everything else)
But its all just thoughts, I think AI singularity would be an entanglement event if it happened.
(would it be irreversible if we wish we hadn't done it).
You would be back to the same question is it the robot that's alive or the energy in it that's alive.. :D

M. Gregg
