What is here? Nothing The Aether – how else could light from the Sunget to Earth througha vacuum?
LIGHT LIGHT MEASURER MEASURER LIGHT LIGHT MEASURER MEASURER IF THE AETHER EXISTS THEN… The speed of light here should be measured as slower than… …here BUT THIS WAS NOT THE CASE
What is here? Nothing The Special Theory of Relativity The Aether – how else could light from the Sun get to Earth througha vacuum? Light is just a form of energy – it doesn’t need a medium to pass through. AETHER THEORY
Star 3. …so the star appears to be here 1. The light ray… 2. …is bent by spacetime…
NEWTON’S TIME Person 1 Person 2 EINSTEIN’S TIME Person 1 Person 2 This has been proven by clocks on the Moon Rocket and Earth – the fast-moving rocket clock recorded less time than the slow-moving Earth clock.
Twins paradox. At lightspeed time stops E = MC² This picture of Einstein writing on a blackboard is 4-dimesional – it shows the 3 dimensions of Space, plus his arm at different points in Time. This means that films are 4-dimensional.
100 yards long A stationary train, as seen by an external observer 80 yards long The same train, moving at 60% the Speed of Light, as seen by the same observer.
The Speed of Light = 186,000 miles per second The Speed of Light squared = 34596000000 So energy = mass x 34596000000
7 x 1018 = 7000000000000000000 (which is a big number)
ALBERT EINSTEIN: THE GENERAL THEORY OF RELATIVITY WAS CREATED AND PRESENTED BY OLIVER MARSH 9MS
