Special theory of Relativity. It is a basic property of Nature that:. Velocity of Light in vacuum is constant.. All inertial frames are identical so if two objects are moving with a constant velocity, it is impossible to do any test which allows to measure the velocities in absolute manner..

If you didn’t get the telescope lab on Monday, pick it up from Johanna.. OUR PLACE IN SPACE. Earth is not special. We do not have any unique place in the Universe. We live on an ordinary rocky planet called Earth, one of nine known planets orbiting an average star called Sun. We are near the edge of a huge collection of stars called the Milky Way Galaxy, which is one galaxy among countless billions of other galaxies spread throughout the observable universe.. Let’s look back at the rotational velocity equation:. v = (M. interior. G/r). 0.5. The rotational velocity is constant at big r values.. What must we conclude?. The mass interior to the orbit is still increasing. Even after the radius r has gone beyond the last of the stars. It must be increasing in order to hold v constant.. .. 1.

Authors Laura Kay and Stacy Palen have developed pedagogy that helps students understand the process of science, and how physical principles are used to discover the origins of the universe. The authors emphasize how we know what we know in the figures, text, and end-of-chapter material.
