Stars whooshing by.....wow. As you know the only star within 4 light years of Earth is our star, the Sun. The journey to the sun would itself take months and months. The only way you would see stars in the distance whooshing by is of the craft was traveling near light speed. I know it is difficult to understand because the distances involved are so vast.
Three hour mark. You can actually see them. Watch the damn video.
Notice how you still haven't actually answered the question? Are you saying it's exposed to the atmosphere during the launch?
How feasible is it that they could create a perfectly airtight chamber that is both detachable but secure enough to survive being stuck on the side during being blasted out the atmosphere, that when it detaches gets far enough away to not even scratch the paintwork?
Don't give me that "But they say they did it!" nonsense. That's completely circular. tell me how you think that is even possible.
You can see the Earth's reflection vanishing despite occupying the same basic location on the car's side; impossible by rotation, only possible by moving far away, but it isn't moving that fast.
Also:
You can see a star to the right there. There is no explanation for that speed.
