Sunshine: the movie that couldn't have been more wrong

Yesterday i saw sunshine,a movie directed by Danny Boyle the star director of Slumdog Millionaire. There were so many scientific inaccuracies in the film which i listed out and some which i read from wikipedia a while ago. The fact is,despite that,the movie seems to keep you glued till the end although it is disheartening to notice that the key parts of the story were based on so simple science portaryed wrong.
The plot is simply that the sun has somehow burnt out and humans are facing winter and hence someone decides for some people to go to sun and ignite it using fusion bombs. Of course,the chances and low and everything like that.

If anyone does not want to read the whole thing the summary of the movie's response is
1. no zero gravity in space
2. effect of sun's gravitation
3. in the end when the docking between icarus 1 and icarus 2 is faltered, the human beings which go out are not blown out like bubble gums which they should because there is no pressure outside and body internal pressure must expand the body.
4. the space suits are gold colored why the hell should they not be white to reflect maximum sunlight and keep them cool.
5.Psychologist is himself mad.
6. i didn't expect it from danny boyle.
nice things
7.they take logical decisions.

The bewildering thing that happens in the movie is that the entire movie is about a spaceship which is in space(no suspense whoa!) and there is no zero gravity. That;s so awesome to observe that in some parts of the spaceship you will get hints of zero gravity like in the aisle these people travel by a toy cycle attached to the ground, but in every other part of the spaceship humans are sitting on the table,sleeping ,having lunch but not floating,even water is liquid there and the food is not frozen. So cool, huh?

Even if we were to assume that the movie starts from a place where spaceship is very close to sun and hence sun being very gigantic has its own gravitational field,then sun must be at the bottom of where these people stand quite comfortably as is the with people standing on earth but it is fascinating to see people seeing sun from the window of spaceship sitting on a bed evidently shown by the spaceship psycologist Dr. Searle.

So far these kind of inaccuracies do not affect the movie's story as such because the whole movie could be assumed to be following those scientifc facts mentioned above but the turning point comes here.
When Icarus 1 and 2 are docked and suddenly the locking mechanism fails the two ships are seperated but then there are four people in Icarus 1 and only one suit in there,so in principle only one can go and one is required to stay behind because of the need to open the door.Now there are two points i would like to discuss, let's start with what i prefer.
No it would be better discuss the story as it is chronologically.
When the discussion inside the ship comes to who would wear the suit, their are two claims, one from the captain of the ship and other from the physicist onboard.The other two support the physcist's claim because he is required to conclude the mission in its entirety by dropping the bomb on sun but the captain insists that he wants the suit.
Here it becomes funny when he says that him being the captain of ship order the physcist to remove the suit and nobody gives a fuck to that.
Now coming to discussion on why these people require suits. Not because there is no pressure outside and hence their body would expand like a bubble gum and explode but because the temperature outside is -273 degree celsius. Now agreed the temperature outside is low but its not absolute zero its 3 kelvin not 0 kelvin as they thought. So the whole agenda in the ship became to protect them from coldness. And they tried to wrap as much insulation around them. Did they not realise that for heat flow you require something to conduct the heat through by convection,conduction or radiation. Surely the body is not radiating heat so fast if it is, and since there is no air in space there cannot be any possible conduction or convection.
And importantly if they could even manage to escape temperature differential which i guess one of them did,they did not burst under the effect of internal body pressure being equal to the pressure exerted by our atmosphere on us.if danny boyle could have only read the wikipedia page on space suits.

Now coming to good points about  the movie
there was no love affair although the wiki page on film tells that danny wanted one but physicst which he was consulting with thought it would be too  embarassing to have a love affair in space.These people are going to save humanity.
Also there was psychologist on board who had the purpose of being the heads on people in place and i doubt he was good at that since he himself was messed up and wanted to see the sun in full brightness and recommended it knowing that it is dangerous.
There were lot of logical talk in the movie which is apparently very rare.When the decision was to be made on who will take the suit to survive other people not being selfish allowed the physicist to do so.
Surprsingly there was only one physicist on board.
There was an earth room in the space ship which simulated earth for people when they were told to do so by Dr. Searle.
