@leicsmacHis views on plastic waste I agree with, surely we need to reduce the use of single use plastics, the environmental damage they cause, which he demonstrated is real and there for all to see. 

 

With regard to 'renewables' I'm probably somewhere between you and him. I don't know what the environmental cost is of erecting, say a wind turbine to generate X amount of power compared with the same output produced by a fossil fuel fired power station. found the image of wind turbine blades buried in landfill quite shocking especially as numbers grow. I feel the environmental impact of renewables is probably not as green or as efficient as it's claimed to be.  Reluctantly I believe the only way to meet our need for electricity is going to have to be more nuclear.

I'm going to be honest, the view on plastic waste is both obvious and the only thing really worth considering seriously in the video.

 

With respect to renewables, as per the last comment, they do outperform fossil fuels in terms of environmental cost already and as the technology continues to mature that gap will only grow. Of course, they cannot do the heavy lifting by themselves which is why fission is going to have to be part of the equation too.

 

These solutions have to be implemented without delay and while power obviously corrupts, I can't see what it has to do with those solutions or what will happen if we do or don't implement them, so what he says about that in the video is essentially pointless from the point of view of environmental future concerns.

There’s been quite an interesting shift in rhetoric, in my line of work anyway, to the acceptance that we will miss temperature increase targets and should aim for an increase of max 1.5 degrees. Imo an increase at this level will cause an incredibly inhospitable world of drought, famine and fire. Therefore given this is now the best we can hope for, we have to build resilience and the associated financing into our infrastructure to cope with a very different world. NOW. Very depressing given this is all man made and was entirely avoidable

@leicsmacI know this guy receives an indifferent reception here, but if you have 20 minutes to spare, I would be interested to know your views on this. To me, it makes a lot of sense, but I'm no expert.

 

I see what he did there.

Interesting font/typeface he's used.

Such images are amazing! However, they all have a huge problem - they're all out of date. This particular galaxy is 500 milion light years away (roughly 5 billion billion miles), so the light we are seeing now set off from there during Earth's Cambrian period, when trilobites ruled the world.

Far more competent leadership back then.

Galaxies were much better back then. Not the artsy fartsy woke galaxies you get nowadays.

And from the amazing, to the "amazing they can manage to leave their own house".

This image has piqued my interest in the Sculptor constellation, which rises above the southern horizon in the UK in late autumn. None of its stars is bright enough to see with the naked eye, but very nearby is the bright bluish-white star Fomalhaut in Piscis Austrinus, the 18th brightest star in the night sky. Sculptor has more than one lenticular galaxy, but perhaps its main feature is that it contains the Southern Galactic Pole according to my Norton's Star Atlas. That's at right-angles to the Milky Way's centre. Lenticular galaxies are fairly rare and are at the 'crossroads' of elliptical, spiral and barred spiral galaxies.

Brazil's government infrastructure clearly cannot be relied upon to do the right thing.

This is what blows my mind. You look up on a clear night and see a twinkle of light in the sky. You think it's happening now.

 

It's not.

You can equally say that anything happening in front of your own eyes down here on Earth is in the past. It just happens to be nanoseconds, plus the few milliseconds it takes for your retina to send signals to the brain and tour visual cortex to process it.

Apparently, the velocity of light has only ever been measured using there-and-back experiments i.e. with mirrors, since it's impossible to know exactly when both the source of light is sent and when it's received by any remote detector. This is because the source and any remote detector cannot communicate with each other any faster than the light beam itself! So the working assumption is that light travels at exactly the same velocity in both directions, even though there's a possibility that this isn't the case.

What I always find fascinating is that quantum entanglement suggests that particles/systems can 'communicate' with, or 'affect' each other instantaneously regardless of the distance between them!

We know that there are areas where relativity breaks down. Inside a singularity is one, that seemingly communication can perpetuate faster than light is another.

 

There's still so much we don't really know and so much to discover.

Why don't they measure it using a ring shaped optic fibre?

After just reading that apparently Russian troops have wired the largest nuclear power station in Europe with explosives, the phrase technology science and the environment might suddenly have a new meaning

To be honest that's just the latest in a long and storied litany of human greed, corruption and lust for power coupled with technology having a potential or actual negative consequence on the environment.

 

It may not even be the biggest current threat in that regard in terms of overall consequence.

I guess that you'd then end up finding the velocity of light at it passes along the cable, rather than in a vacuum. Light travels slower through media such as glass and water, which is why we observe the colours of the spectrum in prisms and rainbows. Even if the light could be sent round a circlular path in a vacuum, that still wouldn't preclude the possibility that its travels at different speeds in certain parts of its orbit.

As regards quantum entanglement (Einstein's spooky interactions at a distance), that's much harder to understand, although I liken it to morphic resonance between twins. Apparently, the concept will have an application with unbreakable encryption systems in the near future. When the transmitted 'keys' are hacked, they'll change behaviour, as will the originals, due to them being quantum entangled, thereby alerting the sender to the breach of security.

Mate of mine is quite pleased with his luscious and green front lawn especially when compared to all his neighbours brown, parched offerings.

 

Turns out he regularly has the hose on it.

 

I know there isn't an hose pipe at the moment in this area, but I feel it shows a total lack of social responsibility.

 

His standout green oasis should be an embarrassment, not something to be proud of.

Keeping lawns like that when we know so much about how bad they are ecologically (for many reasons) is pure ego.
