If you’ve ever wondered what Einstein’s theory of relativity was all about, you’ve come to the right place. Stop assuming so much, and start finding evidence! Lesson 2: Due to the constant speed of light, time is not fixed. Hawking loves the fact that theories can always be proven wrong in the future, and so should you. When he half crashed half landed after 120 feet in the air, the theory was disproven.

That’s what kept 99% of people from driving their carriages over cliffs and jumping out of windows with wings attached to their back.Īccording to the theory, they wouldn’t be able to fly, and some of the people who tried added credibility to that theory. The theory can always be disproven, if evidence against it comes up.įor example, a commonly accepted theory until 1903 was that nothing heavier than air could fly.You can make definite predictions about the future.Hawking says a theory is nothing more than a model, which correctly explains a big number of observations. If you come up with the theory that your software startup needs 1,000 clients to thrive and start turning a profit, you almost instantly accept it as true, which leads to lots of disappointment, should you fail in spite of reaching that goal.

We constantly come up with theories, and then test them. If you want to save this summary for later, download the free PDF and read it whenever you want.ĭownload PDF Lesson 1: Theories can never be fully proven.Īs children we’re all scientists.
