Elon musk hasn't invented anything new, ever.
He is a wonderful salesman, with some really big backers who have set him up as the govern-cement subsidized shill for an outlet for space dreamers.

Sorry all you rocket enthusiasts.

Lets look at the Tesla.  I read how to build such in a book published in the 70s.  And, he hasn't done anything better... except, the sales job.

Similarly, everything that space-X is doing is old stuff.  And they aren't doing it very well.  However, they do not have to.  They are their to put on a show.  They are there to make people have hope and faith that we are still increasing our innovation.

The reality is that The US has a secret space program.  They have flying saucers.  No one uses rockets.  No one believes in such silly notions and gravity and mass.

The truth is we have an enormous amount to learn about earth.  We haven't explored by one tenth of it.  We don't even know what shape it is.  We don't even know all of the intelligent life the lives on the earth.

And this is because we have been lied to.   Systematically dumbed down and kept from knowing the truth.  So much evidence has gone to the smithsonian to just... disappear.

Similar to how americans still believe we are number one... when supposed third world countries have us beat in many metrics.  Our science has become science fiction... to keep the dreamers of space happy.
