black holes- stellar and super massive. Stellar sized black holes are the remnants of massive dead stars that have imploded. It is estimated that our galaxy contains millions of these stellar black holes. Super massive black holes can have a mass millions of times that of the Sun. It is believed that these massive holes are in the center of every galaxy. There may be mini black holes‚ smaller than atoms in volume but as massive as whole mountains. There are some black holes lying between stellar and

exchanging energy with the fundamental particles. This could no longer take place so easily with atoms so the photons filled interstellar space in the form of almost a ’gas’. Over a period of 10 billion years this matter and energy coagulated into stars‚ galaxies and planets and continued to expand‚ forming what we now know as the universe. The big bang theory was initially suggested by Georges Lemaitre in 1927. His proposal came after comparing a model of the universe based on Einstein’s theories with observations

First‚ he discovered the existence of far of galaxies and was able to show the galaxies in all stages of evolution (amazingspace.org). These galaxies had never been discovered or seen before this. The Hubble space telescope also helped answer how rapidly the universe is expanding and for how long. Thanks to the Hubble telescope we were able to determine

What are the four major features of our solar system that provide clues to how it was formed? Describe each one briefly. Four major features provide clues: (1) The Sun‚ planets‚ and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto‚ the planets divide clearly into two groups: terrestrial

occur? Space and time were created in the Big Bang. At the beginning of the universe‚ the space was completely filled with matter. The matter was originally very hot and very dense and then expanded and cooled to eventually produce the stars and galaxies we see in the universe today. 6. What evidence supports the Big Bang Theory? The Big Bang is the leading theory that almost all astrophysicists believe explains the origin of the universe. This is because all observations so far made support

That’s ridiculous. And creation cannot come without a cause. They base this theory on coincidence. I think it’s absurd for someone to believe that this is all plain coincidence. Was it just a coincidence that this timeless “bang” arranged our galaxy in such a rational way that there is an orbit system? Is it a coincidence that all elements present on this planet can perfectly and unconditionally support human existence? Was it coincidence that crafted the intricacy of life? Was it just innocent

Our cosmic address in the universe begins at our galaxy in the local group‚ which is an island of stars in space held together by gravity and all orbiting a common center. Besides our galaxy there are about 40 other galaxies in our own local group. Our galaxy‚ The Milky Way galaxy then goes on to our solar system. Within the solar system there are 100 billion stars‚ the biggest being the sun. The star is a large

Edwin Hubble In this adventure they look will be taken at Edwin Hubble. This look will be into three major areas of his life. His personal life how he grew up‚ whether he married and had children. Also‚ an investigation will be taken to look into his background specifically how he got started in the field of astronomy. Finally‚ there will be a look into what contributions he has made to the field of astronomy. Edwin Hubble would forever change the way astronomy was understood. He would also be a

Cosmic microwave background discovered by accident in 1964 or 65. 3. Relative abundance of hydrogen‚ helium. lithium and boron as measured in other galaxies and even our Sun and other nearby stars is as predicted from theoretical studies based on hydrogen bomb research. 2.
