then how come the sun is on fire?

It isn’t.

its not on fire

it’s not on fire.

(edit – looks like others beat me to it)

And how cme we can breathe on earth which is also in space??

And how come rockets work in space when there’s nothing for them to push against?

And nothing for them to fly through

if only you had paid attention during science lessons…

How come Planet X is a bike company and not an alien porn channel?

‘They Came From In Outer Space’………

Spaceships and conveyor belts…..

Every action has an equal and opposite reaction.

You asked a dumb question and you got a dumb answer.

HTH. 😉

if only you had paid attention during science lessons…

We did. And we paid attention in irony lessons too. 😉

Atmosphere…I’ll let Russ Abbot explain it.

ironing? that was home economics surely…

Here’s the thing. If part of the sun was on fire, would the rest of the sun be hot enough (or whatever it needs to be) to produce enough oxygen to allow that fire to burn?

Ironing was metalwork.
Oxygen was music class

About 0.9% of the sun is oxygen, and it’s the third most common element in the universe

So… my question remains…. howz it do it???

If you’re being serious, it’s not on fire, it’s a nuclear reaction.

let me google that for you

Yep. Just like an H bomb ( the big ones not Hiroshima) but it’s millions of times the mass of the earth and has been continually exploding for billions of years instead of a split second.

Well I never more common than Carbon, but only just

The sun works by converting Hydrogen to Helium, oxygen not needed

rockets move not by “burning” but by expelling part of their mass at high velocity in the form of fuel. best way to do this at high velocity (with current technology) is to burn it; half of the fuel load is liquid oxygen, so that explains where that comes from. Other propulsion systems may be available…

if you chuck some mass in one direction, you will move in the opposite direction. try it next time you go skating

Duh, the sun burns cos of nuckeeur fissushion. To do this it needs Oxygen. It’s soo big, bigger than anything in space. It uses all the Oxygen available in the rest of Space, that’s why. You’re so stewwpid.

I was fine skating when I had something to push against but when I tried it in a vacuum in zero gravity, I got nowhere.

(I know what the answer is, just like I suspect most people participating do to all the questions above), I’m just having a laugh.

The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas,and a process called nuclear fusion is taking place in its core. Nuclear fusion occurs when one proton smashes into another proton so hard that they stick together…and release some energy as well. This energy then heats up the other materials (other protons and electrons and such) nearby. This heating eventually grows out from the center (or core) of the star to the outside, finally leaving the surface and radiating out into space to be the heat and light we know stars emit.

People, including scientists, sometimes say that the Sun “burns hydrogen” to make it glow. But that is just a figure of speech. Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!

Now I can sleep. Nite all. X

Who let this happen???

WTF guys were you all asleep? Slowpokes, sheesh.

What happens if the protons aren’t a very good aim and all miss each other? Does the sun go out?

The sun is really, really heavy. You try escaping from it.

heavy like one of those big heavy bowling balls when you go bowling. the one you pick up and break yer fingers. That kind of heavy? Like, proper heavy?? so you go for the manageable purple one, that’s like Earth, compared to the heavy one’s Sun. I get it now, Space is like bowling. I bet they use this analogy next time Kate Humble fronts a sciency spacey programme!

That ionized plasma is created in an area of the engine with a highly positive charge, and the ions are thus attracted to the highly negative charge of the engine’s “accelerator grid,” which spits them out into space – or, in NEXT’s case, the test chamber – at speeds of up to 90,000 mph.

You asked a dumb question and you got a dumb answer

There’s no such thing as a dumb question. Just dumb people.

Sun (yellow dwarf star) is undergoing a fusion reaction where Hydrogen is converted to Helium.
This reaction releases a lot of heat and light (E.M.) energy.

The Earth has gravity which stops some of the gas escaping into space.

Fancy making them come in on a Saturday.

I would but that’s my day to ride!

Now marking…hoping to ride midday…

O.P. google “fusion reactor” where scientists are trying to build a fusion reactor that gives off more energy than we put in to stabilise it. (To heat water and turn the turbines and mega watts of electrickery! 😉

There IS oxygen in space.

(It’s just spread around quite thinly, so getting a decent breath becomes tricky………)
