How can European scientists send a man from space without him burning up, while American shuttles burn to a crisp on re-entry?

What is the science behind this??

Burnt man ratio will probably increase after a few hundred drops...

>> No.5156536

The shuttles start burning up at a much higher altitude than Felix was at today. Also, he fell straight down and had a starting speed of zero, the shuttle enters the atmosphere and must utilize the friction created to slow down from 17,500 mph.

So you guys believe this wasn't a hoax? on /pol/ the thread about it very quickly degenerated into shitposting and shitflinging and JIDF doing damage control after we discovered jews were behind all conspiracies and jews were the cause of all problems

honestly I'm kinda disappointed that /sci/ seems to believe this is real. scientists should be more skeptical

>> No.5156801

>>5156798
That's because people who actually took logic classes know there is no such thing as a "positive statement" or "negative statement", so claiming it was a fake holds just as much burden of proof than claiming it wasn't.
Also skepticism is about applying your critical sense, not "not believing in stuff".

That's actually how scientific theories work. They are true until proven wrong.
You can't prove a theory right, because induction is not a valid proof.

>>5156812
We're not supposed to "believe" anything. Belief is outside the scope of science.
We study things that are inside the scope of science. An invisible and intangible dwarf cannot be measured or have an effect on our world in any way, so it's not scientific.

I guess you have a point. But religious nuts have lots of values and ideas about how things should be. They also contribute immensely to culture and society.

I guess with scientists they do have values, like rationality. Maybe they just aren't extremist enough and that's why they're kinda disregarded at least by pretty much anyone else who isn't a scientist.
