Assuming they are solar panels, what the **** else would they be sued for you imbecile?

That's why they're so big and frilly GÇö more surface to radiate from.

You should be able to radiate heat though space fine. That's how the heat from the sun gets to the planet from the sun.

...stuff...

You need to reveal this useful secret to the aerospace industry as they've been building spacecraft with them useless radiators all this time. That thar's some serious weight saving idea you got.

modern spacesuits have cooling systems because body heat builds up forever in a vacuum.

there are zero particles in a vacuum, hence zero ways to radiate heat. (...).

In space? Through radiation.

heat is vibrating particles

they aren't part of a radiator system.

No. They have such systems because heat builds up faster than what it can be radiated. It's a volume vs surface thing: astronaut volume (body) generates heat faster than what the skin/suit surface can radiate it while preventing the astronaut from cooking if exposed to direct sunlight (wihtout insulation, heat would move quickly in both directions... inside too utside, but also outside to inside, and you don't want that under direct sunlight within Earth's orbit).

Otherwise radiation is proficent enough to keep ships uncomfortably cold unless they are warmed up. You could go and ask the crew from Apolllo XIII how fast was heat "bulding up" inside their powerless spaceship in the way back home. I'll give you a clue: without their heating systems, the moisture from their breath ended up freezing on the walls...

That wouldn't work very well... can't transfer heat that well into a vacuum.

space is not a true vacuum........... why do people think space is a true vacuum....

a true vacuum would be devoid of matter... space is full of matter

Definition of a Vacuum

The're called "wingy bits"!

there are zero particles in a vacuum, hence zero ways to radiate heat. space does have some particles in it, but they are so few and far between that it would be meaningless. heat is vibrating particles. they aren't part of a radiator system. they are either solar panels, heat *gatherers* (absorbing sunlight), or just there for the same reason everything in EVE looks the way it does - because an artist thought they looked cool.

Finally if the 'sail thingies' are not radiators, then if the current modifications to the Standard Model of the Universe are correct then Dark Matter & Dark Energy could provide the weird particles or energies required for reactor or warp drive to work, in that case the 'sail thingies' would absorb them for the warp drive or reactor!

Uh...solar wind FTW.

From Wikipedia:

'The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun.'

And the crew of the space shuttle, on some of its early missions, noted that the shuttle's heat-shield absorbed heat form the sun and expanded, producing an audible 'roaring' noise within the spacecraft.

Besides, if there was no way for heat to radiate in a vacuum, Earth would be a block of ice.
