Shouldn't the possiblity of Creationism be included? I mean, it makes it sound like the Big Bang is 100% assured of a thing. Not that I'm religious, but I'm speaking on behalf of those who are, and to keep Wikipedia an unbiased place. Also... why is this page so short? --CrazyCasey 17:57, 5 July 2006 (UTC)

Religion doesn't belong in this article. Religious views can be applied to everything, doesn't mean we should list them in every article. It's not a matter of bias, but of Undue_weight. With the way outer space is related to physics and astronomy (specially the cosmology which we discuss), utilizing anything but a scientific tone would be giving whatever other view undue weight in the article.

Please leave my "See also" to the Karman line in: I was trying to search on the no-accent name and missed because the link was re-labeled with the accents. I will propose a rename on the page. -- Fplay 22:55, 21 December 2005 (UTC)

If I explode then will blood come from my eyes? What if the pressure was removed very slowly, from 100 kPa at a rate of say 1 kPa a minute and supposing I had breathing equipment? --Username132 00:17, 29 January 2006 (UTC)

What is the density of air in outer space?

0gm^-3?

There isn't air in outerspace... --CrazyCasey 17:57, 5 July 2006 (UTC)

Maybe he meant matter? There are a few lonely atoms wandering around. I remember seeing this kind of statistics in some physics book. Star Ghost 02:01, 20 July 2006 (UTC)

[edit] Conflict with religion

I don't think this section is relevant, does anyone protest it's removal?

[edit] Link Removal

I have removed the links to website in anther language for 2 reasons. One is they were the same site. Second, they were in another language. More appropriate to be placed in that wiki's language site.

Wikipedia already has a terrible bias towards Evolution and its many unproven theorys and dating methods. As usual this has a terrible effect on readers as more and more people begin to accept these things as fact when any knowlegable evolutionist knows they are NOT facts at all. There is plenty of science that is real fact and disproves the whole "really old earth" theory. "Zealotii 09:45, 15 October 2006 (UTC)"

[edit] In space on the Moon?

Is one in space when on the Moon? I'd say one isn't in space when on a celestial body. Although of course there are border cases, like being on a asteroid. And on Earth you enter space when the air gets too thin, but on the Moon there is no atmosphere. Or is that not the criterium? DirkvdM 07:42, 1 August 2006 (UTC)

The answer would depend on the audience. I, for example would think "in space" means in freefall and outside the atmosphere of any nearby planets, but I think the Man on the Bondi Tram would think that "space" is anywhere beyond Earth, or altenatively, anywhere where a space suit was needed. (days after writing I noticed I didn't sign this) --Polysylabic Pseudonym 04:58, 5 August 2006 (UTC)

Assuming that one is not in space when on the moon, if one was to travel up from the lunar surface, at what point would he/she be "in space"? Would it be the same point at which a person leaving the earth's atmosphere is considered to be in space? Vsst 02:53, 20 March 2007 (UTC)

[edit] Vacuum

The_monkeyhate, do you have any grounds for your assertion that unprotected humans would freeze in milliseconds in space? It's flatly contradicted by the NASA doc cited. SeanWillard 23:57, 12 October 2006 (UTC)

[edit] Their orbits never "decay" because there is almost no matter there to exert frictional drag.

I would like to change "Their orbits never "decay" because there is almost no matter there to exert frictional drag." to "Their orbits never "decay" because the pull of the earth's gravity is canceled by the centrifugal force of their tangential velocity"

I have removed this business. Orbits do decay!. The Hubble Space Telescope gets raised every time it is serviced to keep it in orbit, for example. In geosynchronous orbit, there is a lot less matter than in low Earth orbit, but it still is a issue and all satellites have a rocket and spare fuel to deal with this. --EMS | Talk 17:12, 5 February 2007 (UTC)

[edit] Outer space *vs* inner space

I realise that the popular media use the term "outer space" for everything, but it is my understanding that "outer space" refers to space outside the solar system, while inner space (or plain "space") refers to space within the solar system.

--Black Walnut 12:11, 16 January 2007 (UTC)

Hehe. I came to this talk page specifically to criticize the use of the stupid "outer space" term. For such to exist, there must also be "inner space", which is a ridiculous conecpt. Also, religion shouldn't be mentioned. That's ridiculous too. --194.251.240.114 23:19, 25 January 2007 (UTC)

[edit] I'm Confused

This isn't necessarily questioning the legitimacy of the claim..but a source would be helpful. 32 km (105,000 ft) - Turbojets no longer function. 34.7 km (113,740 ft) - Altitude record for manned balloon flight It just seems..odd, to me, that a manned balloon flight could fly above the point where turbojets no longer function.

[edit] Milestones to outer space

The 62,000 km figure is totally wrong. Earth has more gravity than the Moon so this point has to be most of the way away from it. 320,000 km Earth altitude is more like it (the distance from the earth to the moon minus 62,377 km). Also, this might make a reader think the moon's zone of influence is a "layer", rather than the small sphere surrounding the moon that it is. Sagittarian Milky Way 09:11, 13 March 2007 (UTC)

Yes, I'm pretty sure the author mis-read the Apollo 8 article about this. Wasn't it 62,000 km from the Moon? Trojan_points#L2 puts it at "61,500 km from the Moon." Sdsds 05:02, 20 March 2007 (UTC)

The thing is, the moon's distance itself varies by almost as much as the 62,000 km, moving the balancing point in and out. Does it even matter? (for example, many of the spacecraft orbits are given only as an approximation). Also, perigee is wrong, I'm going to change it. Sagittarian Milky Way 03:02, 23 March 2007 (UTC)

You're absolutely right: the distance to the L1 balancing point doesn't matter so much. What really matters for most mission planning is the delta v required to get there. If you can get there, and if you're willing to wait long enough, then a clever sequence of gravity slingshots can get you anywhere in the universe using only minimal thrust. (See Interplanetary Transport Network.) In that sense, this point does matter, because it's the nearest place "beyond" the Earth's gravitational domain. Sdsds 00:59, 24 March 2007 (UTC)

Right, the cool thing is that it's a bubble of extraterrestrial gravity, deep inside Earth's Hill Sphere. What I meant though is that since the milestones to space altitudes for the ISS, Mir, Skylab, etc. are approximate then the L1 distance can be too. The section looks much cleaner that way.
