Astrophysics is the study of astronomical objects through the principles of physics. Astrophysicists try to understand the intricacies of our universe by examining things like the sun, solar system, exoplanets, dark matter, black holes, the interstellar medium, and other relevant parts of our cosmology.
For an advanced program, consider the 4-course Astrophysics XSeries from Australian National University. Start by exploring exoplanets, planets that exist around stars other than the Sun. Over 1000 planetary systems have been discovered and this course teaches the methods astrophysicists use to find and study them. Additional courses explore the mysteries and theories of the universe including black holes, supernovae, white-dwarf stars, neutron stars and the most violent explosions in the cosmos. Conclude with cosmology, a look at the universe as a whole, the nature of time and space and recent breakthroughs that will help solve some of greatest mysteries of our galaxy and beyond.
ttc black holes explained pdf free
Supermassive black holes, quasars, planetary systems to support life -- all the most mysterious and unique components of the universe are in these courses, designed to ignite your interest in theoretical astrophysics. Astronomy and astrophysics provide the building blocks for understanding our place in the universe.
By developing a general theory of relativity incorporating gravity, Einstein launched a revolution in our understanding of the universe. Trace how his idea that gravity results from the warping of spacetime led to the discovery of black holes and the big bang.
Stephen Hawking showed that black holes emit radiation and therefore have entropy. Since the entropy in the universe today is overwhelmingly in the form of black holes and there were no black holes in the early universe, entropy must have been much lower in the deep past. 2ff7e9595c
