Rings true for me.

Interesting idea... but I don't believe that Elon Musk thinks our current world is only a one in a billion chance of being "real".

I'd take another thought experiment. Let's imagine that in a thousand other video worlds there is a cataclysm. The world is wiped out. How would such an event effect a person living it through a computer ? A bit scary but when you close the computer down you can step outside into the real world.

It is much like the especially vivid dreams which seem very lifelike .. unlike you properly wake up.

On the other hand if we blow our real world for keeps then the next time we wake up it will be in ... ? We certainly wont be re booting Game of Thrones et al. In my view there is more tangible reality on earth than in a computer network.

But I have to say the mathematical concepts of parallel universes is fascinating.
 
Metal Memory

I was just introduced yesterday to the concept of metal objects that can be twisted into all sorts of shapes and then thrown into hot water and immediately returning to the shape they were before the distortions.

WOW!! Looks like magic (In fact this is the basis of a few magic tricks). Quite fascinating and worth a diversion for an hour or so.

It also looks as if new developments can make this product quite revolutionary

This Breakthrough Shape-Memory Metal Practically Never Wears Out

A new shape memory material stays strong even after tens of millions of transformations. It may finally pave way for widespread usage of the futuristic materials.

Can you elaborate on that a bit for us GB? Like who specifically is saying that on behalf of the skyfairy brigade?

Sorry, just saw this now. A: The non-dualist religions (includes Gnosticism, Zen, Buddhism, Christian Mysticism, Taoism, New Age thought, Neo Platonism... etc etc). In non-duality, there's no sky fairy. If they ever use the word 'God', it has to be carefully interpreted, because they're not speaking about a man with a beard, a thing or even an experience.

Does any mechanically minded people on this forum know or know how to find out the following :-

What is the advantage of using Octane 98 over 95 or 92 fuel in a car engine?

Does it offer improved fuel efficiency, higher performance and less engine wear?
 

Google, read, evaluate ??
 
The more octane, the more energy, so the less feul required if the car is tuned to tske advantage.

Higher octane does not mean more energy. They all have the same energy content in the fuel. Higher octane rating just means more resistant to detonation, or pinging. High performance engines that are built for and tuned to the higher octane fuel can make more power due to using more ignition advance, increased compression ratio, or higher boost pressure. If your car is not tuned to take advantage of it, you won't make any more power. You only need a high enough octane rating so you don't get any pinging. Any higher octane rating than that won't make any difference.
 

I fell for the myth.

How many people here follow Professor Brian Cox ? Exceptional scientist and communicator. Just watched his latest series on The Forces of Nature.
Fascinating ideas and the trips to various parts of the globe and different cultures to explore the ideas is brilliant. Well worth the time.
