Our place in the Universe

Our Place in the Universe Science is the process of creating ideas and the “what” and “how” of the universe. What is our place in the universe? How did we end up here? What even is the universe? To start off, I define the universe as all matter and energy that exists. 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 glowing ball of gas that generates heat and light through nuclear fusion and orbiting it are 8 planets. The third planet from the sun is planet Earth, our planet. The only planet from which we know can sustain life therefore us, human beings. This aspect of our universe still doesn’t tell us exactly HOW we came to be. Although we don’t exactly know the answer to this, we can get extremely close to the beginning of time starting with the Big Bang Theory. The Big Bang Theory is the theory that the universe started with an explosion of matter at high densities and temperatures. The Big Bang expansion occurred about 13.4 billion years ago consisting of several different stages of development. After the explosion came inflation and afterglow light patterns. The period of darkness afterward known as the dark ages then turned into the creation of some of the first stars about 400 million years ago. Thus, the further away we look, the further away in the past it is. Another mystery about our universe is if we can actually see all of space. Since the universe is 14 billion years old, if we try and look 15 billion light years then we would be trying to look before the universe existed and wouldn’t possibly be able to see anything.
And to just think that our universe is still expanding today…
