The Study of Celestial Objects When we were born‚ we did not know how vast the world really is‚ we were convinced that this Earth was the center‚ the only place in this world. However‚ growing up we come to accept that Earth is just a piece of the infinite universe‚ and one might even say Earth is not even an atom compared to the cosmos. It took humans thousands of years to discover the reaches of the Earth‚ we finally were able to capture the whole planet and create a map of Earth. Yet the universe

speed that electromagnetic waves travel at which is 300m/s and this means that the wave frequency depends on the wavelength. The wave frequency for gamma rays is 300/0.03=10000hz. Gamma rays are produced by violent events in the universe such as supernovas and the destruction of atoms‚ black holes are also sources of gamma rays. Gamma rays can also be produced on earth by nuclear explosions and radioactive atoms. Gamma rays can be used to see deep into space‚ satellites use a process called the Compton

scientist observed that the supernovas are becoming dimmer‚ which means they are getting closer instead of farther away. They were able to show that dark energy has an influence on light particles and photons. When a photon passes a galaxy it falls into the gravitational pull‚ and the dark energy because it repulses gravity makes the photon pass right through the galaxy with even more energy than when it entered. These findings make dark energy completely independent of the supernova observations. Astronomers
