Black hole

have not visited my grandfather’s house since he passed away 11 years ago. However, my mother did leave out an important detail which was that the house was haunted. With negative feelings on hand, I was on my way to what I like to refer to as the black hole. This trip to Mexico was the moment where everything in my life changed. I knew that any fears or negative…

The great Neil deGrasse Tyson once said something along the lines of humans have only discovered about 4% of the universe. Not only does my fear of what I don't know going on below my feet in the ocean scare the crap out of me, but that big star filled sky does as well. It doesn't just scare me, but it probably scares and excites scientists studying it all over the world. Since we only know a fraction of the inter-workings of the universe, there are many questions and things going on that we…

The speed of light is the ultimate speed limit in the universe. Which travels at 3.0 x 108 m/s in a vacuum and always moves in a straight line. When light travels to a new medium its speed and direction will change, this is called refraction. Materials have different optical density so light rays travel at different velocities. Refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium. Calculated by the velocity of light in vacuum divided by velocity in a…

Joint Probability of Non-Independent Events For the joint probability of non-independent events A and B, we need to use a conditional probability. For P(Zargon-AND-Abduct), we cab use P(Zargon|Abduct) or P(Abduct|Zargon). P(Zargon) x P(Abduct|Zargon) = 8 /20 x 3 /8 = 24/160 = 3 /20 P(Abduct) x P(Zargon|Abduct) = 6 /20 x 3 /6 = 18/120 = 3 /20 Here is a different problem. The UFOs are invading, and the military shoots two special UFO missiles. The missiles blow up two of the UFOs. What is…

Hello there. I will be talking about Olbers’ Paradox. In the year 1826, the German astronomer Heinrich Olbers’ proposed a controversial question about what makes the night sky dark if the universe contains an infinite number of bright stars (Newton 1). This question fascinates me because every celestial object that can be observed with our eyes, should have an important reason and role to play. The paradox about the night sky was also argued by Kepler as stated in his “Conversations with the…

Dark matter is matter that cannot be directly seen because it does not interact with light. This mysterious matter makes up the majority of mass in a galaxy. Although we cannot see dark matter we know that it is out there because we can see it effecting the motion of the stars in a galaxy and gravitational lensing. The first piece of evidence for dark matter is in the way we have observed galaxies moving. You would likely expect their behavior to replicate that of the Sun and the planets, with…

Jake opened his eyes and coughed out some blood. His chest hurts like crazy. Then, he remembered the missile targeting his helicopter. The last thing he could recall was jumping out the door of the helicopter as he heard the screams and cries of his fellow soldiers. Jake gritted his teeth and tried to shake the image and sounds out of his head. He grabbed his pistol a few feet away from him. Jake stood up and surveyed his surrounding, clutching his ribs. Miles and miles of sand and gravel. He…

Gravity is the force that maintains our solar system. According to http://curious.astro.cornell.edu/, the sun is held together due to gravity.The sun formed from a large collapsing cloud made of gas and dust. All objects or bodies in the solar system are affected by the gravitational pull of the sun. Without the gravitational pull the sun would not stay near our planets. This shows that gravity forms our solar system because it holds together the sun which keeps the formation and the…

WASHINGTON: Scientists have surprisingly built up an approach to decide the vicinity of solid attractive fields profound inside using so as to throb goliath stars a procedure like medicinal ultrasound. Attractive fields have critical results in all phases of stellar advancement, from a star's arrangement to its destruction. Presently, surprisingly, astrophysicists have the capacity to decide the vicinity of solid attractive fields profound inside throbbing goliath stars. Analysts utilized…

Cosmos episode 13, “Unafraid of the dark”, begins by talking about the vast amount of scrolls and information that was kept in the library of Alexandria. Many of the books and scrolls were lost when the mob attacked and destroyed the library. This is shocking because of all the history of Ancient times that he's been lost due to the destruction of these books. Although we lost many discoveries, we as humans continue to learn new information about the universe. This begins the discovery of…
