I work near a big Ford place, they appear to be trying to shift this. It is so dull that light bends towards it.

50 grand, haha

It's better than the iD4 (which isn't saying much) and it's way better than it's sister car, which is outright offensive:


On the other hand I saw my first Polestar 4 today and it looked really good; shame it's mad money because of tariffs on Chinese EVs.

That's the new Capri, right? I saw an ad for that and wondered wtf they were thinking.

This is how you electrify classics. 1 off, unfortunately. (Opel Manta)

First drive: Opel Manta GSe ElektroMOD review | Autocar

Opel’s electric restomod of an original Manta coupe is a fun one-off, but it’s also the touch paper for a battery-powered Manta return

Anyway, I've earned my low mileage spurs, ~30k in 10 years, trips included, so now enjoying my drive to and from work, a tank of posh petrol a week at the moment.

I got to sit in the new polestar (a friend of mine is local marketing manager), with all the bells and whistles it's ludicrous, I'm not sure why the drivers seat needs to also be a massage chair but it was neat

There's no back window either so rear view is just a screen with camera feeds which was a bit weird

Our Milky Way galaxy is big. But do you realise just how big it is ?

If you scaled the Milky Way to the size of North America, our Sun would fit between two ridges on the swirls on the tip of a finger.

I still believe that there is life in other areas of the Universe due to its size and number of planets coasting around a Sun. We believe that all life has to follow our environment but bollocks to that belief, we found life on our planet in the most extreme inhospitable places, gas vents at the bottom of the ocean for one.

 

[Raven]

I 100% think there is life elsewhere, the question is, can the travel to us? With OUR technology, no. With technology, 10,000, 100,000 into the future, possibly.

Are 90% of sightings made up and 9.99999% easily explainable, yes.

Imagine what we could achieve if we didn't want to kill ourselves and our planet so much?

Good reading. Fermi paradox - Wikipedia

 

[Scouse]

Meh. I think there's life *everywhere*. But if it was long-lived then we'd have detected it by now.

Imagine a civilisation that lives for 10,000 years emitting radio waves (which they would all do). Any of the approx. 1 billion stars within ten thousand light years of us that had an existing civilisation we'd have detected by now. Any that are further afield - say within our galaxy - we would not be unlikely to detect if life was common - as everyone says.

The only real conclusion is that, like us, life evolves and then we get to human-levels of intelligence, but technology keeps evolving - and we all experience either civilisational or planetary collapse - so our radio-waves only exist for a few hundred years. That makes them easy to miss - ships passing in the night.

So, I think, loads of life, doomed to relatively rapid extermination.

 

[Lamp]

Just on the numbers alone I am of the opinion that the universe is abundant with life. There are over 2 trillion galaxies. Probably a lot more. Each galaxy harbours quadrillions of planets. The chances of us being the only planet with conditions conducive to life is small.

The problem is that interstellar space is vast. Even if you could travel at the speed of light - which you can't - even 400 light years is an un-survivable travel time. Each civilisation is trapped in its own solar system, unable to traverse the vast distances or break the laws of physics.

I believe there are no Star Wars Cantina like alien races. I think all intelligent life will be human, or as close to human as makes no difference. Across the cosmos there are intelligent beings just like us, looking up at their version of the night sky, asking the exact same questions. Are we alone ? I think even though we can never meet any other intelligent life, I am comforted by the fact that we are all pondering the same issues.

 

[Lamp]

The distances between stars in galaxies is enormous. In 10 billion years from now, the Milky Way and Andromeda will merge. There is unlikely to be a single collision between any two stars when they come together because each star is separated from its neighbour by a huge distance. The Universe is bigger than you can possibly imagine.

Yep - but their light - radio transmissions - isn't. So we should be able to detect it.

Either our detectors are shit, or the gaps between signals don't last long enough (a few hundred years) so the chances of detecting it are slim. But if civilisations live tens of thousands of years, we should be able to prove they exist because the signals, when they pass earth, will be passing us for tens of thousands of years too...

...but they're not (or we're shit).

We have only used radio for ~130 years, and it is already creaking, will we be using it in 100 years? Unlikely.

Quantum entanglement (which I won't even pretend to understand) has some interesting "things" and could be used for communication. (1000 years, 100,000 years into our future and so on)

Or, in other words, trying to detect radio, might be as much use as trying to pick up native American smoke signals, from London.

 

[Lamp]

Remember in order to detect something the return trip is 2 x light speed

So a message to a civilisation 400 light years away (practically next door in cosmic terms), takes a total of 800 years to make a round trip back to Earth

 

[Lamp]

Quantum Entanglement is not to be confused or conflated with faster than light communication.

Quantum Entanglement is the process by which two quantum objects (such as electrons) become interconnected so that the state of one instantaneously influences the state of the other (eg if one electrons is Spin Up, the other will be Spin Down). This is NOT faster than light communication. No information is passing between the two objects. They simply share the same single wavefunction.

Faster than light communication is not allowed. Period.

 

[Lamp]

@Zarjazz is the authority here on physics, and I defer to his expertise

 

[Raven]

Faster than light communication is not allowed. Period.

Yes, I understand that, but I am not talking about direct a message to us, or even a broadcast into space, but general static. radio will be long dead in 100 years, probably, at least long distance, so it is useless to try and detect (a few hundred years in a 100,000 year long civilisation, or millions of years on a multi-planetary species) we would have to be incredibly lucky to find another civilisation based on such a small window.

Edit, and even then, faster than light is only impossible with our current understanding of physics, which is largely theoretical. We used to believe faster than sound was impossible (in atmosphere) but that didn't last long.

 

[Scouse]

Nope. To detect a signal, it only has to reach you.

To talk to someone, 2x light speed.

But identifying that radio waves aren't just background radio would be trivial. So all they have to do is get here, then we can go "aliens exist".

 

[Scouse]

radio will be long dead in 100 years

Why? It's incredibly useful. We can replace it on earth for stuff (and have). But in space communication, less likely.

 

[Lamp]

Yep, you're correct of course. Two way traffic is 2c.

Imagine an alien civilisation 5 billion light years away. They send out messages in every direction. The Earth will be destroyed by the Sun before we receive them. That's IF they are targeted accurately. Space is big.

 

[Lamp]

The reason its impossible to accelerate an object with mass to light speed is because you would require an infinite amount of energy to move the object

E = mc^2

 

[Raven]

It's not useful at all, it takes forever to send/receive, and is already a problem for communicating with things on Mars, literally our next door neighbour.

If we knew the future, we wouldn't be waiting for things to download. Shit analogy, I realise, but really, we are barely above chucking spears at each other.

 

[Raven]

Over physical space. 300 years ago, sending messaging through the air? Impossible.

 

[Lamp]

Fantastic ideas like the Alcubiere Drive rely on physics that simply doesn't exist, like negative energy ! It's pure science fiction

 

[Lamp]

Light speed is nature's maximum speed limit. Only two exceptions are

(1) The exponential inflation of spacetime immediately following the Big Bang
(2) The velocity of infalling spacetime inside a black hole

In regular Euclidean or Hilbert Space, nothing with mass can propagate faster than c

I think the possibility of quantum pairings could potentially be faster than light? You have an array of quantum electrons lined up in a binary fashion. For our purposes of keeping it simple: One byte.
One part of the array is 00000000 . Quantum entanglement means the other side is 11111111. Quantum entanglement doesn't care about distance. You have a pair of these (one receiving, one sending). You launch one pair into space, keep the other on earth. Instead of beaming back stuff via radio, you just use the quantum entanglement functions to communicate. You're not traversing space / time to communicate, so E = mc^2 does not apply?

 

[Lamp]

I'm not an expert - @Zarjazz is

AFAIK, when you take a measurement of an entangled bit you collapse the wavefunction of the correlated bit but no information is transmitted. You still need classical systems to communicate.
