If you're into space, you've probably heard that reentry capsules should have a blunt shape in order to push the shock wave away and reduce heating.
If you've ever wondered why exactly the shock is pushed back by a blunt body, and how this reduces heating, this video will hopefully explain it for you, without diving deep into the maths.
Also discussed in the video is why a blunt body is not always the best shape for reducing the heating of a reentry vehicle.
