1. Einstein's theories are all mistakes.

Photoelectric effect theory won him a Nobel. Later he admit it was mistaken. All these fifty years of conscious brooding have brought me no nearer to the answer to the question, 'What are light quanta?' Nowadays every Tom, D i c k and Harry thinks he knows it, but he is mistaken. -Albert Einstein 1953

He thought gravity able to slow down light. If a star has enough mass, its light will be slow down so much and make it invisible, so black hole.

In reality, all star lights have the same speed C. Real black hole is in every toilet. 

He thought the sun's gravity able to bend light so at solar eclipse we can see stars behind the sun. 

In fact, hot plasma on sun's surface reflect/bend those stars light behind the sun. So those dumb scientists able to took a picture back then to support his theory. 

He thought nothing can travel at light speed due to unlimited energy is needed. 

Mistaken, he don't even sure what is energy/quantum.

All the motion is caused by force, electrostatic force. f=ma, enough force able to push matter at any speed.

But force has a speed limit, electrostatic force and gravity have same speed as light speed. A train travels at 100 m/h cannot push a man to 101/m/h.

E=Mcc is mistaken. Matter is matter, formed by charged particles. Energy is force that able to accelerate/move matter. How could the 2 equal?

2. Solar sail and EM drive both will not work.

Sun light has NO momentum. Solar sailing is a lie/mistake. Easy to proof, if sun light has momentum, how about Army laser? Those laser able to ignite missiles miles away, but not able to spin a light mill in hard vacuum. Why? Light is vibrating EM force, not photon/quanta particles that carry momentum. 

EM drive is impossible. Without mass ejection in space, there is NO momentum changing, no force to accelerate. 

3. Maxwell was wrong.

There is no electric field and magnetic field reproducing at right angle and move at light speed, no transverse waves travel in space. 

Why? Because both fields must have force carrier/charged particle to carry it. But space contains none. 

Free electrons in a conductor synchronized vibrate, produce vibrating EM field. Other free electrons in other conductors follow the vibrating energy/EM force and vibrate at the same frequency. That is the true mechanism of EM waves.
