You do realize that second stage engines exist because ground level engines aren't efficient in a vacuum? Try reading a book sometime. Learning from a guy who makes internet videos instead of rockets is not going to teach you anything about rockets.

Oh, and religion is make believe.

Of course.

Unfortunately, that doesn't fix the problem, because when there is zero atmospheric backpressure the rocket efficiency is going to plunge in the same way.

The second stage rockets use the same bell shaped design, so the improved efficiency is temporary. The same problem exists for all rockets.

Some may be more efficient, but getting to 100 miles from the surface in this way is a tall order... ;-)

Oh, and religion is make believe.

It sounds like space flight is your religion, cause you'll apparently believe anything they claim. :-/
