ok this has been bugging me. I already blocked the sender but I got an ask earlier for an OLD ass post on my main blog where this fucking chud tried to mansplain physics to me and I just.

I cannot get over this bro telling me that ram air isn't why things burn up on re-entry, and then trying to bullshit some pseudoscience physics about how the vibration of the atoms rubbing on the object plus the atoms sliding across it's surface is what causes it.

No that's not how it works and the fact that you dug up a six year old post on my blog tells me you have nothing better to do than start shit with people and would simply put your fingers in your ears and yell LALALALALALA if I tried to flatten you with the actual physics.

Things don't just burn up on re-entry, modern supersonic aircraft ALSO heat up due to ram pressure in flight, to the point where the X-15 - with a skin made of ICONEL (a nickel-chromium alloy) which is a superb heatsink, fucking started MELTING in flight. Concord had problems with heat from ram air. The Blackbird leaks fuel like a sieve because it's components were made too small on purpose to account for thermal expansion due to - you fuckin guessed it - ram air.

See in physics gases do this funny thing when compressed and heat up. No heat is added, so much as the heat energy in a given volume of gas is now forced into a smaller space and thus the temperature rises. Compress it enough, like when you're forcing something through the upper atmosphere at 4,520mph or coming back down from orbit at 17,500mph or more, the pressure put on atmospheric gases causes them to heat up, and that heat is absorbed by the object.

Love a long lean Ponty with a big snout? Well, this Auto World die-cast portrays a powerful 69 Grand Prix with a prominent nose!

JFC, that's good.

I have jumped out of perfectly good airplanes before. The instructors where I did it had an Air Force test parachutist. When he landed, he just touched down and stood there. The canopy remained floating above him. Then he bowed and the canopy fell forward at the extent of the lines. Amazing.

This though... I don't even comprehend the physics. The momentum forward is created by the parachute wing giving resistance to the air by gravity pulling down.

Where is the down?!?! It doesn't appear windy through the tunnel to give lift. Doesn't look like they skidded on their butt and the parachute was more of a drag chute. There shouldn't be any lift. Why is there lift?!

*pants*

Okay, one thing did occur to me - the road may be at a steep enough grade for that to happen. But you normally don't tunnel down like that...

Gah.
