Star Trek Tech Made Real - Transparent Aluminum

Ok honestly.. its is not about transparent metal aluminium. You know that aluminium oxide is the stuff that is used in for example you garden variety fuse, yes? Nothing magic, in fact aluminiun is of the most common substances in the earth.

Scientific fact: transparency and conductivity are opposite, for some reason. There are some interesting materials that are used in the very screen you are looking this post like indium tin oxide, but they are not metals as you think of metal. They are more like rust, brittle and fragile.´Metals (and metal alloys) are malleable, strong - and for shining!

So far science does not know a substance that behaves like a metal, but is transparent.

I'm not saying its not possible, but it would be worth a Nobel at this point.

Well, I suppose its as much about belief as anything.

Like time travel. Is is possible or not? Many physics theories do not forbid it.

Myself, I prefer the multiverse theories. That means that you cannot kill your grandfather - in some realities you did that and in some you did not.
What this means is that there is no time-travel causality... I'd suggest you to read David Deutch: The Fabric of Reality. I'm on same lines with him on these matters..

I'm one of those who don't believe that time travel as we normally think of it in sci-fi is possible. I understand how mathematical models can make it seem possible, but switching variables around on paper or in a simulation is very different than undoing a physical sequence of events. This gets quite involved, but there's a logic to the impossibility. I just doubt most people have reflected on it long enough to grasp it.

Did you all notice, that there is a huge flying wing US military drone going about?
Its really huge, over 50 meters (140 ft??) wingspan.

Its replacing the Global Hawk thing, that explains its numbers going down.

It was for really short time in the press, they are redacting it as we speak!

One 2c, is that there is really a huge black military budget, and it actually goes to military projects, based on normal aerospace research...

Just that _one_ drone program eats easily a billion usd!

There are a whole range of legal & ethical issues associated with using an AI generated image. How do we know if the actual person is the person in the video? Will famous people have to renegotiate their contracts to include special licencing for AI generated likenesses? Is it really such a great idea to create a computer so powerful it can trick us into thinking it's not what it really is?
