GENERAL RELATIVITY (1915)

SPECIAL RELATIVITY (1905)

VS

• Focused on observers that were moving with with a constant velocity motion (fixed speed, fixed position).[3]
• At constant velocity motion, an object would be squeezed and compressed, along the direction of that motion.[5]
• The outside world, on the other hand, would undergo wild distortions (due to the impact of constant velocity motion on space and time.)

• Motion in which the observer is undergoing accelerated motion.[2]
• In this case, the move from constant velocity to accelerated motion 'brings in' an understanding of the force of gravity.[2]
• Includes warps and curves in the fabric of space and time. [4]

Did Einstein's wife contribute to his theory of special relativity?!

INTERESTING APPLICATIONS AND IMPLICATIONS OF EINSTEIN'S THEORY - 'The twins paradox'

• When astronaut Scott Kelly spent nearly a year aboard the International Space Station commencing in 2015, he was moving much faster than his twin brother.
• Astronaut Mark Kelly, who spent the year on the planet's surface, due to time dilation, aged just a little faster than Scott — "five milliseconds," according to the earth-bound twin.
• Since Scott was not moving near light speed, the actual difference in aging due to time dilation was negligible.
• So, considering how much stress and radiation the airborne twin experienced aboard the ISS, one may would argue Scott Kelly increased his rate of aging.[9]
