/c/TenFoward: Your home-away-from-home for all things Star Trek!
Re-route power to the shields, emit a tachyon pulse through the deflector, and post all the nonsense you want. Within reason of course.
~ 1. No bigotry. This is a Star Trek community. Remember that diversity and coexistence are Star Trek values. Any post/comments that are racist, anti-LGBT, or generally "othering" of a group will result in removal/ban.
~ 2. Keep it civil. Disagreements will happen both on lore and preferences. That's okay! Just don't let it make you forget that the person you are talking to is also a person.
~ 3. Use spoiler tags. This applies to any episodes that have dropped within 3 months prior of your posting. After that it's free game.
~ 4. Keep it Trek related. This one is kind of a gimme but keep as on topic as possible.
~ 5. Keep posts to a limit. We all love Star Trek stuff but 3-4 posts in an hour is plenty enough.
~ 6. Try to not repost. Mistakes happen, we get it! But try to not repost anything from within the past 1-2 months.
~ 7. No General AI Art. Posts of simple AI art do not 'inspire jamaharon'
~ 8. No Political Upheaval. Political commentary is allowed, but please keep discussions civil. Read here for our community's expectations.
Fun will now commence.

I did some math. Volume of TNG bridge: 480,000 liters. 1 person breathes 8 liters per minute of air. That's not using up all the oxygen but it's how much you would use without any oxygen reduction at all.
480,000 / 8 = 60,000 minutes of air before noticing the air is stale.
60,000 minutes / 11 crew on the bridge (including Wesley) = over 3 days of no air before they'd even notice that oxygen was lower.
What about temperature regulation? Lights? Water? Food? It’s not just air that’s “life” support.
I think entertainment is also included, so TVs, music, etc. that’s all put on the side burner when life support goes down, it’s a large portion of power if you include everything and not just “oxygen”.
TNG enterprise reactor creates 12.75 billion gigawatts and has a crew of around 1000. For comparison, One World Trade Center uses 110 mega watts for 8,000 people.
Edit:
A better comparison is the ISS which uses an absolute maximum of 17kw per astronaut for lights/computers/air/water/heat.
That's 17 Megawatts for the Enterprise ~1000 crew?
So that's 17 *10^9 / 12.7 *10^18 =
Life support uses about 1 billionth of the Enterprise's power.
Data: Shields are at 10%
Captain: Transfer life support to shields
Data: Shields are now at 10.0000001%
Vakuum has no temperature. Maybe a problem close to a star. And that bit against infrared loss...
You know we have a space station up there?
What…? Space is incredibly cold unless you have the warmth of a sun to warm you up, so you would always need heat, or AC at any given time. You can shut turn these lower to save power and find and optimal orbit for heat or something, but yeah, temperature regulation in space is crucial.
Space has no air to transmit temperature. Well, maybe a few atoms of hydrogen and dust every m³ (and they do have about -200°C if i remember right), depending on where you are, but that does nothing. Only way to transmit heath in space is via radiation. You lose a bit of warmth via infrared radiation but i doubt that a crewed spaceship has no insulation. And the 400k liter of air in Enterprise should be an adequate buffer.
That bit about inszantly freezing in space is Hollywood, same with firey explosions.
You don’t instantly freeze, but you will freeze since space is incredibly cold, regardless of no atmosphere to transmit temperature. It’s still cold and you need heat to survive in any situation unless you are close enough for radiation from the sun.
Radiational transfer is still a thing even though conduction transfer can’t happen.
Why do you think you need to heat AND cool something depending on where you are in space? And if space couldn’t transfer temperature the sun could never warm us, there is obviously more than one way to transfer heat here…..
No one said anything about INSTANTLY feeezing. Try not to be so smarmy while completely missing the point.
