Space travelling big question
0 2018-03-15 by lolo425
Yo redditors, I was just recently thinking about the moon landing conspiracy and I came up with one really common sensed question based on a candle and a glass and the fact that there is no air in space. So if u lit a candle and cover it with a glass the candle will stop burning because there it no oxygen. So if in space there is also no oxygen how the hell then do the spaceships travel because they use fire to travel and fire is made out of fuel, heat and oxygen. So without the main component which is oxygen I don't think it would be possible for the fire to keep burning which would mean that they would be unable to travel.

Rockets use solid or liquid fuel which is ignited inside the rocket and expelled backwards...the force of the ignition moves the rocket forward because there is oxygen and fuel on the inside. It quickly stops burning once it leaves the rocket but equal and opposite reactions of Physics means the rocket moves forwards.

but wouldn't it use oxygen tho?
1 bradok 2018-03-15
There is Oxygen stored in tanks inside the rocket.

Yes...which is why they have oxygen in the rocket
1 lolo425 2018-03-15
I don't really think they could store enough oxygen to keep them going to be honest.

Why not?

Considering the distance to the moon. It just seems to me like it would run out much faster before they got to the moon.

They don't run the engines all the way there. Just until they escape Earths gravity.

I mean maybe, but if they don't then they must have complete lack of control over the ship. Also on nasa's video once they got to space they was just floating and the takeoff looked to me like a complete animation (shown here on exact moment https://youtu.be/zsJpUCWfyPE?t=9m55s) and just the fact that you can't comment on that video makes it even more dodgy.

This isn't a conspiracy, this is basic science and engineering.

First, they don't need to control the vehicle beyond what they do. Your imagination is no replacement for calculation. Once the vehicle is headed in the correct direction, it will keep going in a straight line.
Second, there are lots of other ways to control the orientation of the vehicle, look up a "rate control system."
All of your arguments here have been an appeal to how you aren't educated on this subject, so you don't understand, and it must not be true. That's dumb.

You don't seem like you're very well-informed about all this, so nobody sane is going to value your perspective. You're also wrong. Sit down.

These kind of posts make me wonder about people's thought processes.
Why would one not just type this into a browser and learn with one fucking click how things burn in space.
He answered his own ignorant question in the question... almost.
I think the real conspiracy in this post is how well the fluoride plan is going.

I see this so often that it's becoming kind of frustrating.
"I don't understand x, so x must be fake/wrong/a lie..." where x is some well-established math or science that anyone could learn the basics of, if they were so inclined.

And if you get irate and frustrated and are insulting they cry to the mods and you get three days off.

I haven't lost my cool yet, but a three day vacation from the nonsense might actually be a good thing once in a while, heh.

No, it uses an oxidizer, which could be oxygen, but it could also be something like nitrous oxide. The first thing you have to learn here is chemistry. Most fires consume oxygen, but combustion is just a type of redox reaction, and other oxidizers can work in the place of oxygen. This is why funny cars use nitrous oxide.
As for rockets in the vacuum, they either have liquid oxygen on board, or some other oxidizer. To make ignition easier, it's normal for them to use self-igniting hypergolic mixtures, which you can look up on Wikipedia.
Also, don't get confused about where the combustion happens. The glowing exhaust is not burning. The fuel and the oxidizer burn in what's called the combustion chamber, and the exhaust is mostly the glowing already-combusted product of that reaction.
In a solid propellant and in an explosive, the oxidizer is already mixed with the fuel before the ignition occurs.

The fire is kept going and created internally/inside the engine of the craft.

My take on what happens to astronauts who play with fire in space. https://www.designbyhumans.com/shop/apollo-astronaut-grim-reaper-skull-illustration/855136/

Rockets wouldn't work at all in so called "outer space." The entire thing is just a massive hoax. The moon landing is just the tip of the iceberg.
1 BronyJoe1020 2018-03-15
Yes, they would. Tell me why otherwise.
1 whenipeeithurts 2018-03-15
Prove it.
1 BronyJoe1020 2018-03-15
The burden of proof lies upon you because you made the original claim, but I will humor you nonetheless. It is very simple: Newton’s Third Law. For every action there is an equal and opposite reaction. This is easily observable in any environment. The reaction made in a rocket’s combustion chamber does not require oxygen.
1 whenipeeithurts 2018-03-15
Newton's third law doesn't work in a vacuum. "Outer space" only exists in your imagination.
1 BronyJoe1020 2018-03-15
Why would Newton’s Third law now work in a vacuum?

I can’t look at this video currently, I will when I can, but there is still undeniable evidence that forces react equally in a vacuum.

Space travel doesn't exist, but not for reason you stated. Solid fuels carry oxygen. They don't use oxygen from air.
