Space is a vacuum therefore heat (kinetic energy in atoms of matter) wouldn't exist?
There is no air granted, but you would still burn up before you got anywhere near the sun. Streps said:

What happens to the storm troopers after the end of the 6th film?
They form the Imperial remnant http://starwars.wikia.com/wiki/Imperial_Remnant

Why do they still use a bible to get people to swear on even though the people in it and taking the oath may not be religious?
There are several options - you can swear on the bible or other relevant holy book, or simply affirm (declare that you will tell the truth). My own preference is to use whichever version the jury (or bench) is likely to be expecting - I have no particular religious beliefs, but am paid to tell the truth.Why do they still use a bible to get people to swear on even though the people in it and taking the oath may not be religious?

why does a thermos need reflective lining to keep heat in, if heat can't cross the vacuum?temperature doesn't exist in a vacuum though

Heat energy can be transferred by - oh hang on, it's in the CGSE syllabus : http://www.bbc.co.uk/schools/gcsebitesize/science/...
Only two of the transfer forms require a medium, the other is pure EM radiation.

Two phrases ive always wanted to know the meaning of,or at least since they first appeared a couple of years ago.
I seem to be hearing these phrases numerous times every day now -
"Think Tank" WTF-ing hell is a think tank???
"Payday Loan" has some sort of industry sprang up in recent years which caters for people who need to borrow money on the same day they recieve their wages? or am i missing something?

No. They take out a (ludicrously high interest) loan and then pay it back on pay-day.CBR JGWRR said:

What's the temperature in space?
-270 degrees celcius (ish)the temperature in deep space is roughly 3 Kelvin / -270C, but it can vary and as you might expect it gets warmer in the vicinity of hot objects like stars

the heat energy can cross the vacuum. the vacuum prevents heat loss by conduction and convection, but not radiation, which does not require a medium.Edited by Hugo a Gogo on Friday 24th February 19:33
the reflective lining is to minimise the loss of heat through radiation, which happens mostly at infrared wavelengths (just a bit too long for us to see) in the case of delicious tea.
the only difference between radiation at infrared wavelengths and visible wavelengths is the wavelength itself, and as such IR radiation will be reflected back inward just as effectively as visible light.
also edited. still a 'tard.

there is heat , but no temperature
temperature is a property of matter, a vacuum is the absence of any matter
heat is energy

the heat energy can cross the vaccuum. the vaccuum prevents heat loss by conduction and convection, but not radiation, which does not require a medium.Edited by Hugo a Gogo on Friday 24th February 19:33
