OK, so now you're encrypted from user to Cloudflare, in plaintext within Clouflare, and possibly in plaintext from Cloudflare to the destination site. That's more an illusion of security than real security. Even worse, if they have an SSL cert for your domain, they can impersonate you. Worst case, they have some cheezy cert with a huge number of unrelated domains, all of which can now impersonate each other.

LAX just runs people through huge powered revolving doors to enforce one-way traffic. They used to have a sign that said "Once you have passed this point you cannot return".

We get a warped view here in Silicon Valley. Lots of Teslas. No Supercharger stations, though. There are a fair number of electric car outlets around, of too many varieties.

This is no big surprise. All the mammals have surprisingly similar DNA.

True. My Android phone has no Google account, so I disabled Google Account Manager, Google Bookmarks Sync, Google Contact Sync, Google One Time Init, Google Play Magazines, Google Play Movies and TV, Google Play Music, Google Play Store, Google+, Market Feedback Agent, and Picasa Uploader. No major problems.

Do you need me to post the distances that you did not understand?

kilometers 350,000 is about Earth to the Moon
kilometers 200,000,000 is about Earth to Mars
kilometers 39,900,000,000,000 is about Earth to Alpha Centauri

Light travels about 1,000,000 kilometers an hour.

So what you're saying is that from a million plus kilometers away, a ship with a forward profile of maybe a few score meters ...

That is just 3x the distance from the Earth to the Moon.

And only 1/200th of the distance from the Earth to Mars.

And that isn't even counting the kilometers of shielding that you kept insisting upon.

area of a circle = pi r r
So a circle with a radius of 2 kilometers (you've proposed larger shielding) would give an area of 12,566,400 square meters. Which should be very easy to spot at 1,000,000 kilometers.

It's the laws of physics. And the math isn't that difficult, either.

deviating from the formula is almost always a way to make a crappy book

Go grab the last 20 titles in any genre. You'll see that most of them adhere to the tropes of that genre and are still crap.

A good author can write a good story even with the most formulaic plot.

A good author can write a good story even while subverting the established tropes of the genre.

But that's not important in this specific case. Martin can still change the specific tropes for individual characters in order to "twist" the ending from the predictions. (Boy meets/loses/gets girl) becomes (boy meets/loses/dies-in-battle-to-impress girl who married the local royalty once boy had left).

Since the "mathematical model" was wrong there, who's to say it isn't also wrong in X?

Nevertheless, this statistical approach to literature could introduce the process of mathematical modelling to more people than any textbook.

Until the writer reads that analysis and intentionally deviates from it.

In which case you've just shown them that mathematical modelling is unreliable.

When the real lesson should be not to use a tool for a job for which it was never intended.

I'm sorry, that reference went right over my head...

You just quoted my explanation "rapid expansion of the propellant in a vacuum in addition to the above mentioned thermal radiation".

I quoted you to point out that your explanation was not an explanation. Explain how the exhaust will cool to background radiation levels.

I didn't bring up Voyager, that was brought up by the article on the impossibility of stealth in space.

I'll quote you, again:

Similarly, the two Voyager spacecraft have easily detectable signals because those signals are directed by a high gain parabolic antenna at Earth, because the signal has a narrow bandwidth, and because there's a huge dish at Earth to pick up the signal.

That is what you posted. And they will take 300 years to reach the Oort cloud.

You first have to show that.

Easy. I'll use the analogy of Harry Potter and the Cloak of Claimed Invisibility.

You claim that a cloak of invisibility is possible.

I say that physics says it is not.

You say that it is possible ... as long as you use tactics to take out anyone who isn't blind.

I say that if it was an invisibility cloak you wouldn't need tactics to take out anyone who isn't blind. The cloak would make you invisible. They would not see you. Tactics do not beat physics.

But you keep insisting that the cloak makes you invisible ... as long as there isn't anyone who can see you.

Except it won't be glowing.

Tell me more about how it is going to cool off to background radiation levels.

Unlike the spacecraft itself, rocket exhaust (chemical or otherwise) will cool rapidly to the microwave background temperature (rapid expansion of the propellant in a vacuum in addition to the above mentioned thermal radiation).

You are claiming that. But you have not explained how it would happen.

Sure, all of this can be detected by a large enough and sophisticated enough detector.

And you've just contradicted yourself.

If the exhaust has cooled to background radiation levels then it would blend in with the background radiation. It would not be detectable. No matter how "large enough and sophisticated enough detector" there was.

To claim that physics prevents stealth is to ignore the actual physics as well as tactical considerations like the size and mass of a viable detector.

And you've just contradicted yourself in that single sentence.

Tactics do not beat physics. So there is no "as well as". You've claimed that the exhaust would be as cold as the background of space while still driving a ship fast enough to cover distance X in time Y.

Not unless X is approaching 0 or Y is approaching infinity.

Like your previous example of Voyager. Which you did not like once I pointed out that it would take 300 years just to reach the Oort cloud.

There was no "them", only one point.

And you keep complaining that I addressed them. It was your post. If you did not like it then you should not have posted it.

This is remarkable. You were the one who started banging on about interstellar distances (and then interplanetary for some mysterious reason), not me.

Because distance is the point.

You do not understand that. But I will explain it again.

kilometers 350,000 is about Earth to the Moon
kilometers 200,000,000 is about Earth to Mars
kilometers 39,900,000,000,000 is about Earth to Alpha Centauri

Light travels about 1,000,000 kilometers an hour.

So the exhaust from your example ship will, eventually, disperse beyond your example shield. When that happens, the radiation given off by it will travel at about 1,000,000 kilometers an hour. That means that the math for determining when the enemy will see your ship's silhouette is very simple.

Not in the least, I'm arguing that the heat from the exhaust would have reached negligible levels by the time whatever miniscule amount of it got around the shield, mostly due to the vast majority of it being blocked by the ship and being blasted directly backwards.

I've already given you an example of a laser from Earth to the Moon. Here it is again.
"At the Moon's surface, the beam is about 6.5 kilometers (four miles) wide ..."
https://en.wikipedia.org/wiki/...
So you are claiming that the exhaust from your example ship is MORE tightly focused than a laser is.

The laws of physics disagree with that.

And as another poster pointed out to you, the exhaust isn't nearly as hot as some might imagine.

You don't know how hot I "imagine" it to be. All it has to be is hot enough to be detected. And since the instruments today can (probably) detect leftover radiation from The Big Bang it looks like the laws of physics contradict you again.

And yet again nobody is talking about going from Earth to Mars except yourself.

That is the distance that you quoted. Whether you understood what that meant in actual terms when you quoted it I'm sure that it sounded good to you when you posted it.

What you posted was:

So what you're saying is that from a million plus kilometers away, a ship with a forward profile of maybe a few score meters ...

Now "a million plus kilometers" might sound impressive to someone who does not understand the actual distances in space. But that is just 3x the distance from the Earth to the Moon.

And 1/200th of the distance from the Earth to Mars.

So, yes, detecting an object at that range is easy.

And yet again nobody is talking about going from Earth to Mars except yourself.

I'm pointing out that you do not know what the distances you are quoting mean in the real world.

It the laws of physics.

That's quite correct, and not an exaggeration. The "City of London" (now a tiny part of London) has a governmental structure left over from the Middle Ages. (It was codified in 1189AD, but is older than that.) It's one of the few holdovers from the feudal era that hasn't been modernized. The City of London Police should have been absorbed into the Metropolitan Police decades ago, but haven't been.

To buy or not to buy.

That is the question...
