WEEK SIX-POST ONE

• Einstein found out gravity and acceleration may be the same thing
• Acceleration can mimic gravity
• When someone in a fast elevator going up can feel heavier, that is acceleration mimicking the earth's gravity getting stronger, while if it was descending, it would feel as if the person we suddenly lighter and earths gravity was decreasing
• This is called the Principle of Equivalence
• The equivalence of gravity and accelerated motion
• Einstein thought that acceleration also had to be a theory of gravity
• Einstein said matter bends space
• When a heavy object in space attracts a smaller object, it is due to the heavier object bending space. Therefore, the smaller object is attracted to it, almost as if on a downward slope on a flat surface. This is what we call gravity
