      Additional methods for detecting planets around stars are taking a photo and seeing it (direct observation), gravity of a star and planet bending the light of a farther star (gravitational lensing), transit timing variations, transit duration variation, astrometry, and more. Expert. Calculate a planet’s mass and radius from transit and RV data.

      Note that both gravitational lensing and gravitational red-shift can be explained by the curvature of spacetime. The picture shows a simulated black hole of ten solar masses as seen from a distance of 600 kilometers with the Milky Way in the background. Notice the gravitational lensing effect. Just for fun . . .

      Notice the gravitational lensing effect. Light gains potential energy as it climbs the curvature of spacetime and so must lose some of its energy. Losing energy results in a lower frequency. Note that both gravitational lensing and gravitational red-shift can be explained by the curvature of spacetime.

      2. According to the general theory of relativity, a gravitational lens is the phenomenon in which the gravity due to a massive body between a distant object and the viewer bends light from the distant object and causes it to be seen as two or more objects. 3. Since 1979 many examples of gravitational lensing have been found. 4.

      Gravitational lensing is a technique used to determine the size of galaxies. Einstein’s theory of general relativity states that matter curves space time. Therefore, mass will bend light, and even dark matter will bend light. Astronomers can determine the size of galaxies by determining how much light is bent.

      Look up the form in a math tables book. Now, if we started from rest, then u1 = 0 and u2 = u and . Therefore, we define the relativistic kinetic energy to be . The quantity mc2 is called the rest energy, because it’s independent of u. The total relativistic energy is E = K + mc2 + V, where V is the potential energy, if any. If V = 0, then . b.
