This is the fruit of university education. Inability to argue without ad hominem, inability to remember the simplest things, and inability to grasp concepts.
No, that is the fruit of your lack of education and intelligence.
See how you continually fail to grasp concepts, or just lie about them, and then throw out insults like you have done yet again.
That's exactly what it is.
Not quite.
You can call someone a moron without it being an ad hom.
The ad hom is when you call them a moron, to dismiss their argument.
Like you have done often.
Now again, care to stop with the insults and deflections and try defending your blatant lies, or being honest for once in your life and admitting they are lies?
On the contrary. The more I learn about ignition, thermodynamics, buoyancy, mass, propulsion, the more implausible the idea becomes.
You mean the more convoluted BS you think up while ignoring reality.
You cannot show anything implausible about it.
You were even provided examples of ignition in a vacuum, which you ignored.
The science of propulsion (quite literally rocket science) falls apart because it asks us to ignore what we see in reality
No, it doesn't.
Your objections do.
a simple balloon filled with helium has a height limit. Planes have a height limit.
This line of complete absence of reasoning is like saying cars drive along roads, so planes can't be real.
A rocket is not a balloon nor a plane.
It does not fly like them.
A limit on them says nothing for a rocket.
If space travel were actually real, the ship would use the main shuttle to very precisely boost itself and the reserves tanks into space.
No, it wouldn't.
This is not you making a rational objection, this is you spouting pure BS with no justification at all.
If sending objects to orbit in space is real, the object would be burning fuel very rapidly, and ditching as much useless weight as possible.
To get into low earth orbit, it requires the object to be going at roughly 8 km/s. That will require a quite substantial amount of fuel to do. And there is no point in carrying around empty fuel tanks when you do so.
And yes, that is the main energy cost.
Assuming it starts at the rotational velocity of Earth, some ~450 m/s at the equator, and goes to a LEO at 8000 m/s, that is change in specific energy of ~32 MJ/kg.
To get up into space at 400 km altitude, ignoring the reduction in g, is a mere ~3.9 MJ/kg, or ~10%.
So they are using that fuel to go fast.
And once the tank is empty, that is dead mass to carry around.
Without oxygen there can be no ignition.
And they carry their own oxygen supply, so here you are spouting BS again.
You have nothing to push off of.
Except the exhaust gas coming out of the engine at very high speed.
If you want to say there is nothing to push off in space, then that is saying that if you have a tube full of highly compressed air, with one end open, it will magically stay put because there is nothing to push off.
Yes, I know better.
Then why do you continue to spout this pathetic BS which could easily be refuted by a child?
But since they aren't used in space, I know immediately that the entire rocket science is built upon fraud.
Correction, you hate the idea of space because it shows your fantasy is wrong, so you look for pathetic BS to attack it, even though that BS has been refuted before.
If you know anything about space, it is that you are intentionally lying about it.
You have yet again demonstrated either your dishonesty or your stupidity.
I can change definitions of terms
No, you can't. That is just more dishonesty from you.
This is because my definition change is an expansion of original concept whereas yours is a distortion.
PURE BS!
Your pathetic attempt to change the definition goes directly against the original definition.
The original definition of buoyancy, which entirely matches the modern understanding complete with gravity, is an upwards force which is a result of weight.
Your delusional BS is nothing like that that and instead wishes to pretend that weight is just buoyancy.
You want to be able to change it, because you are a lying coward that cannot face reality.
For about three seconds.
Because of the limited fuel and oxidiser supply.
If your delusional BS was true, it shouldn't light at all.
Have you watched the video?
Why should we waste our time watching a crappy video likely full of already refuted lies, when you put no effort in at all?
How about this, admit all your claims have been blatant lies and then maybe we will?
is this an actual test?
Yes, it is.
It demonstrates that you don't need oxygen from the surrounding environment, and the vacuum tests demonstrate that you can ignite in a vacuum.
Again, if your blatant lies were true, they wouldn't ignite at all.
When you threw away the boosters, you invalidated everything.
No, they didn't.
They only thing invalid is your pathetic strawman.
The boosters are your source of oxygen
They are 1 source, not the only one.
you can use them to press forward even if no other oxygen exists.
Or you can use the fuel and oxygen in the main craft, ignite it and use that to push foward.
That's not how any of this works
Your strawman certainly isn't.
Stop pretending
The only one pretending here is you.
if space flight is real, in an airless environment, you would want to bring the boosters.
Why?
What point is there in bringing this dead mass?
There simply isn't enough fuel to last them months in space
What are they using fuel for months for?
