Here's another example of the straw man.
You're claiming that the Laws of Thermodynamics are straw men.
Physics shows that you are wrong.
Sure, you can't make a detectable object perfectly undetectable by definition.
You can when there is a planet between you. That is why stealth works on Earth.
That is why stealth fails in space.
It's about being much harder to detect so that various militarily-useful activities can be conducted such as sneaking up on some target and shooting it.
Light travels at over a million kilometers an hour. Which means that anyone you are sneaking up on will have hours of advance warning.
There is no such thing as a perfect detector - among other things it would need infinite area both to observe perfectly and to store the infinite amount of information it received.
Who said it had to be perfect? I'm pointing out that your exhaust will be radiating heat in all directions. Over billions of kilometers. Maybe trillions of kilometers.
And that light will be travelling at a million kilometers an hour.
And I already explained how rocket exhaust can cool that fast.
No you have not. You just keep repeating that it will.
The universe has been cooling for billions and billions of years.
Why would the exhaust cool to that same temperature in a day?
The Laws of Thermodynamics say you are wrong.
It's physics.
