If you got superman powers and could fly in space how would you make sure you didn't get lost?
Was thinking of bringing a camera that could somewhat tell your position based on star constellations, but wouldn't that only work inside the solar system?

You're marooned in your spaceship with 5 minutes of oxygen left when some ayys hail you.
Through ayy magic they contact you and say they can prepare a room for you on their ship.
But they need to know what conditions, atmosphere and such the room needs to have for you to survive.

What do you tell them?

>banan tastes pretty dry
>wonder how much water content it has
>probably just 23-030 percent
>look it up
>mfw it's 70-80 percent

My next semester is starting in two weeks and I just got a mail from our teacher lady which says
>coming semester is theme 5
>Construction and Project Planning

Well that's not very definitive.
Any suggestions to be prepared?

Researching the elctromagnetic spectrum. Shit's weird.

But I can't figure out what determines the range of wi-fi routers and cellphones. In my world the more power you add the longer range but the higher power would also change the frequency?

Copper wire can create a "deadzone" where wireless infomation and and wi-fi in general can't go through.
Can someone take my hand and explain to me like a 6-year old how that works?

The only thing I can resemble it to is the tesla-cage where one can stand inside and get hit by lightning but not.

>UFOs are seen near mars
>a rover on the planet captures them landing
>creatures destroy the rover
>a message is sent to earth
>simple infographic
>we now live on mars
>if you try and get to us we will fuck you up
What do?

Would we just let them take Mars or go full MURRICA and fight them?

One of those simple lines that makes you think, thank you anon.

How fast does a meltdown at a nuclear power plant happen?
Asking to figure out if there would be time enough to call for a superhero if the world had one.

If there would be time enough what would this person have to do? Remove some fuel rods?

Meltdown 101 go.
