Why in the prologue people are astonished by "floating rocks"? Why do they point it out?

Here the thing you don't understand. The consent of what a vacuum is. General in science they are 3 types that are referred: perfect vacuums, false vacuums, and synthetic vacuums.
Perfect vacuums, though a consept, can't exist because it a concept of an area have nothing in it. That's impossible to do even in space. You would have to take everything,including dark energy, out which impossible to do. Space is called a vacuum because it's close to the consept of a perfect vacuum. Stating something is a vacuum does not mean it has nothing there, it also mean a state of a vacuum can happen. And that is what happen on the habitat 7.this happen with the gas of oxygen. With Boyle's law a state of a vacuum can happen due to the pressure and volume of gasses. If you you take a gas element in a container and take to place where it does not.exist and make a hole in a contianer, a state.of a vacuum will acute as it leaves the container.

My point is that is what happening with Alec Ryder when he dies.

1. State like a vacuum can because in atmosphere.
2. And it can be cause by a lack of a gas via Boyle's law. Which is based on pressure and volume.

I get this.

I don't know where I got the information, but I did understand that at least the Scourge was attracted to Remnant spacefaring or active drive core technology, and that is what Ryder used in the finale.

I don't know how often the Scourge just moves randomly though. I never saw it in game, and it looks pretty static on planets. If it does just move randomly, that would make the navigation charts that Sarissa stole from the Kett kind of useless. Unless those charts can predict the movement to some degree, which would be interesting.

Yes, he was in a state of a vacuum. Oxygen was being sucked out of his lungs. He jist talked while it hapoen befire he passed out. Also,the oxygen is not needed for us to speak, we can talk with near any gas in our lungs, we just can't live with any gas in our lungs.
I already pointed out what happen to a person who is on mars with no space suit.

With the low atmospheric pressure in comparison to Earth, death would occur in minutes. This vacuum like pressure would rupture both skin and organs. That might hurt.

If by any “chance” you survive that, you would probably die from the large temperature ranges.

The average annual temperature on Mars is -64*F, ranging from -199*F to 80*F throughout its revolution around the sun.

If you were to bypass that, the lack of oxygen would get to you- and fast. Compared to earth’s 20%, mars has 0.1%, not to mention intense UV radiation, surface chemicals and oxidants.

As stated before. Habitat 7 has little oxygen.

Yes it is an issue of a state of a vacuum. As I said many times it's a law of physic of gas for it to move from on area to another based in volume and pressure. If you have a container of gasand bring it to a location where that gas is not and open it the gas leave that container and make a vacuum like state temporarily. Eventually it does end but it does happen.it boule's law.

Oh my, you REALLY don't understand Boyle's law.

dude, if it was a case that it was death by suffocation alone that they could both live by trading the helmet. But being that this is an environment that lacks oxygen I know for a fact that it would get sucked out of there lungs.

no, the vacuum would be at the mouth of the continent not the total room. It with be a partial vacuum and it would be temporary. And then it would be based on how much pressure is in the container or in the room. Any ammont of a container would have have some level of pressure in it due to the volume of what's in it.

Yes, they probably could've done, at least if both had remained concious. Maybe that was Alec's hope, but seeing that Ryder Junior was passing out realised that that wasn't an option, because the unconcious Ryder wouldn't have been able to hold his / her breath when they needed to.

If anything the planetary atmosphere would've been forced in, since the Habitat 7 atmospheric pressure is higher than 1 bar (on the assumption that the suit provides air at 1 bar pressure).

ConciousNess has nothing to do with trading that helmet. Alec put that helmet on Ryder on his own mean come keep it maintain on his own. And Alec passed out in secs. In a non vacuum state you do not pass out in secondservice, it would take up to 4 minutes for that happen at the most. If the air was not being sucked out of Alec lungs he could just trade the helmet and live. You don't pass out in seconds like Alec and Ryder did unless the air is being sucked out of your lungs.

If the pressure of the atmosphere forced the air out of their lung that it means a state of a vacuums happened. That's how particul vacuums work.

I never "hated" on the game.   If I had to rate it, I would give it about a 6/10.   If anything, you are "hating" on the fact that I would question anything about the game.  I offered to agree to disagree on our different feelings in a civil tone about the opening, but you cannot seem to allow that.  I dont know why you are taking such an intolerant stance in a "discussion forum".  I am not attacking you and your feelings about the game on a personal level.

I disliked the Angara and Jaal, as written.  Other people love them.  I dont tell them, "piss on your feelings about the angara".  

You are severely confused.

1. The atmospheric pressure is GREATER than Earth's. His body would not be expelling "oxygen" as there's no void (pressure) for it to be sucked out by.

2. Oxygen itself is not the issue. Our atmosphere has just shy of 21% oxygen in the MIXTURE. Habitat7 could be comprised of 80% oxygen and still not be conducive to human life. The idea behind that law you're quoting (and vacuum in general) is pressure variance. Not round peg-round hole (not simply oxygen so the atmosphere's composition automatically pulls the oxygen from his lungs. His lungs would collapse if this were the case. Hab7 would not filter through the air mixture in his lungs for "what it's looking for.") Oxygen at this point is the least important variable.

3. Nothing is being pulled from Alec Ryder's lungs. He is continually breathing, and speaking.My point in that he is speaking is to point out the fact that his lungs are in no way depressurizing.

4. Consciousness would have everything to do with trading helmets periodically over the course of four minutes. Holding your breath is a CONSCIOUS effort, and the issue with Hab7's atmosphere is less the absence of approx 20.95% oxygen in its mixture, but likely the other 79.05% that makes it toxic to humans.
