Guided Notes – General Relativity and Black HolesName:Tracey RochaThese notes cover slides 37 – 52 ofVideo Lecture – Stellar Evolution.For slides 37 – 52 please type or handwrite notes as you watch the video lectureand answer the included questions.General Relativity-To understand what happens to very massive stars (>25 Msun), we need to understand some physics.-Einstein’s general theory of relativity extends special relativity to cases of acceleration (changingvelocity)-We can treat gravity as a curvature of space (and time). Mass bends space.-Straight paths are “bent” because space is curved.-In general relativity, we can measure time being affected by gravity and space. The most basic change isthat time moves more slowly the deeper into a gravity field you go.-Redshift: Light wavelengths shifted longer when going uphill.-Gravitational Lensing: Gravity bends light. Observed with entire galaxies or single stars (microlensing)-Gravity Waves: Accelerating large masses create waves in space. Can only indirectly be detected.
