Question everything.

Speed of light is limited because it is kinetic energy propagating through a medium. This subatomic medium was once known as the :luminiferous ether" by engineers. Then some crackpot (Einstein) that couldn't invent a working fridge came along. He supported the government story of gravity and became a celebrity. In the shadows, Nazi scientists knew it was bullshit so they spied on engineer Nikola Tesla and copied his gravity model. This is how they were able to create flying saucers in Germany. "Foo fighter" UFOs. in the late 1930's to early 1940's.

Imagine making a wave in a tub of water. Can you make it go faster? No. Same concept. There is a limit because of the medium. This means a spaceship can go much faster than the speed of light if it can behave as a (encapsulated) particle.
