Special relativity and general relativity
Einstein - Answer- Nothing is absolute
Space and time are relative (like frame of ref)
Space and time are forever connected
Before Einstein on space - Answer- Connected universe
Contains all things that exist
We live and move in it
Before Einstein on time - Answer- Constant rate for everyone everywhere
Light travels at - Answer- 300,000 km/s = 3 x 10^8 m/s
Doesn't travel through time
Move through space --> - Answer- Move through time
Moving --> Travelling through ___ - Answer- Space-time
Time is changed
Travel closer to the speed of light - Answer- Travel faster --> time slows and travel
through space
Standing still and time - Answer- Still Travelling through time
Time-dilation - Answer- Time slows when you move near the speed of light
Stretches time
Einsteins special theory of relativity - Answer- How time is affected by motion in
space at constant velocity, and how mass and energy are related
First postulate of special relativity - Answer- Object can measure its speed relative to
other objects
Assumes our inability to detect a states uniform motion
We can detect an accelerated motion though
First postulate theme - Answer- Uniform motion
All laws of nature at same in all uniformly moving frames of reference
Second postulate of special relativity - Answer- Speed of light in the vacuum will
have the same value regardless of the motion of the source/observer
Speed of light stayed when truck moved
Ultimate speed in universe - Answer- Speed of light
Speed = distance / time - Answer- It takes more time to go greater distance
Einsteins correction factor - Answer- So it doesn't go at speed of light
