Why we will never leave our Solar System

[ping111]

Salutations. After a quick refresher in science class (followed by a YouTube session) gave me a shocking truth.

We will never leave our solar system.

Humans exert their own pressure, which is why we grow taller in space. However, even in what we call 'zero gravity', we are still attracted by the Earth. So, if we reach 'deep space', in which we are not in the SOI of any planet (which would be very hard to find), we would die almost instantly. Why? Because if we\'re not attracted to anything, it can\'t compress us, and our inner pressure would outdo the outside pressure, and we would explode.

Sorry about that.

EDIT: MY 1000TH POST! WOOT!

I admire your logic.

True, we might end up finding ways to create our own wormholes in the FAR future...

Which will allow us to leave the solar system in an instant.

Uhm. No. Molecular bonds work just fine in interstellar space.

The reason we won\'t leave the solar system is a combination of politics, and interstellar radiation screwing with DNA and causing cancer.

[Sordid]

But what if they lead to deep space and we die?

A valid objection.

Clearly the solution is to equip our Sun with a Shkadov thruster and simply take out solar system with us. There, problem solved.

It\'s not about spaghettification, it\'s just about pure explosion. Our inner gases would exert more pressure than the outside, and it would burst out. Think about what would happen if you tried to blow a bubble in a vacuum. The bubble would pop instantly, because the air inside has way more pressure than the vacuum.

DNA is the main killer, we can always simulate gravity by using centrifugal forces or 'spinning spaceships'.

Umm... I can\'t tell if your serious, and are just very... confused about scientific principles, or whether you are joking.

First of all, we will not explode in 0 gravity. In earth orbit that we call 'zero gravity' we are in free fall, this is true, we ARE being attracted by earth. However, there is no force holding us up. What we generally feel is really the \'normal force\' of whatever surface we are on pushing us up. In orbit, all things are falling at the same rate, there is no normal force so all structures in the body float freely.

In true 0 gravity we would not see much of any difference. There are definite problems that are experienced in low gravity, such as loss of bone mass, changes in the cirulatory system, and recently discovered vision problems, but none of these make you \'explode\'. The other thing to consider is a vacuum, as would happen if a space habitat ruptured. In this case even so, you will not explode. Worst case is if you try to hold your breath, without the pressure of atmosphere around you will cause the air in your lungs to expand, damaging your lungs. Otherwise, the main cause of death is lack of oxygen.

As per bubble analogy, your skin is a LOT stronger then the skin of a bubble.

That also has nothing to do with gravity, and everything to do with pressure, which is relatively easy to deal with by filling a capsule with air, and will be not significantly different in low earth orbit, or interstellar space.

[Cooly568]

You sir, are really really smart.

[JupiterII]

When you\'re in suit or ship in space, you\'re in a pressurized room. Also we can create artificial gravity.

Also, you don\'t explode in a vacuum, your body just expands. If you were on a planet that had no atmosphere, you would still expand, just not upward.

Like Bluejayek said, I don\'t think you understand what you\'re talking about.

I was about to mention all about how pressure just so happens to be maintained by these craft we quaint solar system-bound beings like to call \'spaceships\'. And that this maintained pressure prevents us from undergoing rapid decompression.

You have it all wrong. He\'s talking about gravity, not pressure.

[OtherDalfite]

Now by inner pressure, do you mean the pressure people exert normally? Because even if someone was in deep space and not in any SOI, the pressure of the air around us would keep our bodies normal. The real problem is to make artificial gravity.

Yes, I mean gases and oxygen inside us that equal to 1 newton if you convert it.

[Guest]

Well, this really dampens the space spirit.

[OtherDalfite]

That would only be deadly to us if we were OUTSIDE the spacecraft, in the vacuum. However, without gravity, babies couldn\'t develop and be born properly and people may cause aneurysms to pop, instantly killing a person.

Well, i doubt were going to be having babies in space, so we can rule that out.

[NovaSilisko]

I can\'t tell if you\'re being serious or not...

[ping111]

I can\'t tell if you\'re being serious or not...

I\'m not being serious, like a doctor telling a definite prognosis, but I\'m not joking.

[Misterspork]

Um, even if this would happen to a person:

Gravity is a downward force EDIT:(Well, downward relative to the celestial body in question), pressure from our bodies goes in all directions. Wouldn\'t that pressure blow up our arses?

It isn\'t gravity that keeps us from exploding, but rather air pressure, which is rather easy to create.

We can simulate gravity, so that\'s not a problem.

[Rascal Nag]

and our inner pressure would outdo the outside pressure, and we would explode.

He was, in fact. And no, this would not happen:

1. Zero gravity DOES NOT EXIST. ANYWHERE. There is always gravity. Right now our solar system is orbiting the center of the Milky way due to the extreme pull of a supermassive black hole. Even in between galaxies there is gravity, it\'s just very weak. Also, don\'t use SOI in terms of real life, since there isn\'t really a defined thing like that. For example, the oceans may be sitting on Earth but they are still affected by the Moon (tides), since IRL our Moon\'s gravitational force does not cease existing at some certain distance from it. Real life doesn\'t have to deal with the computing problems Squad has to deal with ;D .

2. Gravity does NOT compress us. It only attracts us, and if it is too strong, crush us, but not in the way pressure would. Pressure compresses us, pushing in from all directions (or out in this case), not just pulling from one like Gravity. Yes, in zero gravity one might grow taller as we\'re not being pulled down anymore. But this is not due to low pressure.

3.If anything, in a vacuum we\'d expand slightly in all directions. But not burst. Our body is too tough for that. To be honest, I think you\'ve mixed gravity and pressure together for some reason. You shouldn\'t do that, one\'s a fundamental force, the other is just stuff pushing against other stuff, basically.

4.Though we wouldn\'t burst, we\'d die without oxygen of course. But we have suits for that, so we\'re okay.

[Sordid]

Well yes, but you took that quote out of context. He was talking about our internal pressure, yes, but then he went on to talk about how the gravity of the Earth counteracts it. What say you to that, sir?

In real life, you wouldn\'t even see any expanding, except for the lung area. The compressed oxygen would expand until the lungs either tore, or the air could escape.

If we were going for deep space exploration, yes, we would need to have babies, and those babies would have to have babies.
