"Time dilation refers to the seemingly odd fact that time passes at different rates for different observers, depending on their relative motion or positions in a gravitational field."

"The observer effect is the phenomenon in which the act of observation alters the behavior of the particles being observed."

Mass = Gravity
"Anything that has mass also has gravity. Objects with more mass have more gravity."

Acceleration(Motion) = Gravity
“As Einstein pointed out with his STR, the effects of gravity and acceleration are the same."

Spin(Motion) = Gravity
"The motion of black holes and other massive objects can cause gravitational waves."

"Like most objects in the universe (planets, stars, asteroids, and other compact objects), black holes rotate. We refer to this property as “spin” or, more formally, its “angular momentum” about its axis of rotation."

Gravitational Field = Slows Time
"Time slows down near a black hole due to the extremely strong gravitational field of the black hole."

Speed(Motion) = Slows Time
"The faster the relative velocity, the greater the time dilation between one another, with time slowing to a stop as one approaches the speed of light (299,792,458 m/s)."
