Can you believe that everything in the universe, all of the stars, the galaxies, and even our world, was once the size of this, a mere marble? All that we are comprised of was compacted into this tiny space. And then it expanded into a trillion times its size in less than a trillionth of a second. All of the things we see and hear about and what you have just heard or will hear about, are all a product of what happened, trillions of years ago. Hosted by Morgan Freeman, Through the Wormhole explores the deepest mysteries of existence — the questions that have puzzled mankind for eternity.
Are we alone in this universe? Can we live forever? Can we travel faster than light? These questions have been pondered by the most brilliant minds in history and now, modern science may be able to provide us with answers. Today, we will strap into our spaceships and blast off from this world to see how close we can really get to a black hole; while we are out in the vacuum of space, we will research and analyze what Black holes really are, and finally we will return back to earth and see how these findings affect us. Transition: We will start off by leaving our world behind and going to search for these invisible monsters.
Body: Point 1. ) Now, what’s does the Federal Deficit and a Black Hole have in common? They both never end because According to the National Aeronautics Space Administration in an article last accessed on October 17, 2012, a black hole is a place in space where gravity pulls in so much, that even light cannot get out. This is what makes them invisible. When we look we can see nothing but strange optical distortions of the sky around it from the bending of light that occurs. When we pass the event horizon, or the very edge of a black hole, and enter it, we destroyed.
We’re pulled apart and stretched by the immense amount of gravity, this process is called spaghettification. Our counterparts however, see us freeze in time and eventually disappear because the hole has consumed all of the light being reflected by us. But what about the place where the waste is expelled? What goes in must come out right? Scientist have pondered the existence of a white hole; A place in space where the exact opposite events take place, light and other things containing energy come out. According to Time magazine, last accessed on October 17, 2012 physicist J.
Robert first suggested this in the 1930 and names them white holes because light would come out, making the hole look white. His counterparts continuing his work have witnessed energy coming from the center of galaxies that can’t be accounted for. This provides evidence that black holes have a beginning and an end, the white hole being the end. Btu will we actually ever be able to enter one? Is it possible to go into a black hole and survive? To answer this question, we must first understand how these monsters are created. Transition:Now that we have seen how far we can get to a black hole, let us look as what black holes are.
As we look at this marvelous event, we start to ponder where this hole has come from. Why is it here and how did it get here? Point 2. ) According to an article published by Shazi Irshad from the Universe today last accessed September 9th 2012, there are many theories as to how black holes come into existence. The main theory most scientists come to agreement with is one that Shazi writes about. He says, when a gigantic star reaches the final stage of its life and is about to go supernova (which normally takes billions of years) it spends all the nuclear fuel by then.
So it stops burning and heating up and cannot create the nuclear energy required to feed the star and let it make a pivotal balance to support its own gravitational draw against the intense pressures brewing inside. Therefore its stability cracks under its own gravity. The radius of the star shrinks to a critical size, and it starts to devour anything and everything that comes a bit too close, including light. Gravity does its job and the core of the star caves in and implodes. The outer shells of the star explode into the space and may even fall into the already dense black hole making it even heavier and denser.
As the radius of the star gets smaller and smaller, it starts to spin ever faster than it was before. Since it spends so fast, space time starts to wrap itself around it which creates a tunnel. The tunnel punches through the fabric of space and creates a white hole. Transition:Now that we seen and analyzed what a black hole is, we must return back home to see how these findings actually effect us. Point 3. ) According to Star dates “Black Hole Encyclopedia” in an article last accessed September 9th, 2012, there are billions of billions of these invisible monsters out there.
Thousands of those billions, being right here in our own Milky Way galaxy. Dr. Karen Masters, astrophysics from Harvard, said in an article last accessed October 17, 2012, that the closest black hole is 1600 light years away, which is 96 with 15 zeros after if when converted to miles. So needless to say, it’s pretty far, so no harm will come to us. Sabine Hossenfelder, a phenomenologist from Cornell University, said in an article last accessed August 19th, 2012 that the information that we can obtain from a black hole, can have an endless positive effect for us back on earth.
Questions like, can we actually be able to enter a place in space, and come out from the other end? Are they portals to another dimension or to another time? But in extension, all these questions will allow us to seek a different perspective us where our species came from. Black holes and the way they form may be able to tell us how we as a human species formed. Physics. org, in an article last accessed October 18, 2012, says that it is theorized that before the universe began there existed a singularity, and out of the singularity came the universe.
At some point, matter and energy were ejected from the white hole, and this event was the “big bang,” the beginning of our universe. Conclusion: So today, we saw how destructive black holes are, we then looked at where these monsters came from and finally we looked at why they matter to us, which now brings us to realize that understanding the insides and outs of white and black holes, would answer so many questions that humans have. All the answers, to all the questions we as a human race face, are out there. And millions of scientists around the world are working to find those answers.
Today, however, our scientific studies have concluded what black holes are and what their amazing appetites consist of, along with see what would happen if they were to eat one of us. We have seen how black holes are born and produced from a dying star, along with seeing how they create what would seem to be impossible events. We have then concluded how black holes can help us here back on earth along with opening our minds and eyes to new possibilities. I hope that today, I have, in fact, opened your mind to the fact that one day, we will be able to hold all the universes mystery’s and wonders, in the palm of our hands.
