Transcript of Black Holes

Black Holes Vocab we will be using!! Event Horizon Implosion Gravitational field Singularity Ergosphere Key Points How are they formed? What ARE they? What do they do? How are they formed? A star can either go: SUPERNOVA ...or... Black Hole (Explosion or implosion) What ARE they? What does that mean for us? NASA? Its own gravity becomes so large
that it seems to "suck up" all things
near, in, and around it. NOT
TRUE. Implosion Explosion Consists of... Singularity Event Horizon Ergo sphere By: Ashley Grindstaff & Emily Lauer A single point in the center of the
black hole with infinite density, and
a set mass. 2 Kinds:
Stellar-mass or
Supermassive What do they do? Do they follow laws of physics, and gravitational theories? This is where things get... Complex. Can it affect light? Yes it can!! How? If light gets too close, it cannot escape the pull of gravity. Why don't some people think they exist? What does that mean? Will our star eventually become a Black Hole? NOPE!! Why not? Our star does not have enough gravity to condense, or to implode. Never been direct evidence they exist. Belief in dark energy stars. There's no explanation of dark matter. Belief that the black hole would evaporate at the event horizon. Black energy stars behave like black holes. Are we close to any Black Holes? Not really! Why don't people believe they are real? Its gravity forced it to collapse in upon itself In fact, it doesn't "suck" at all! When you get too close to it, it does pull you in, but if you are outside the Event Horizon and the Ergosphere it cannot really affect you Quantum Transition Phase oh yes...this has been proven.. What would happen if you fell in? What would happen if you fell into a Black Hole? NASA? Is NASA looking into black holes? YES! There are astronomers that search for areas of stars and matter that are reacting to the behavior of black holes. They study the 2 different sizes of black holes : Stellar-Mass and Super massive Also they're looking into intermediate mass black holes which they think forms from a chain reaction of stars colliding in compact star clusters.

http://www.space.com/16080-solar-system-planets.html Learning Goals!! 1. Be able to define all of the vocab words. 2. be able to explain the "Noodle Process" 3. Understand the physics in, and around a black hole 4. Know whether or not our sun will be able to turn into a black hole, and give a brief explanation as to why 5. Be able to recognize the types of black holes A Black Hole is a dead star Many Scientists have theories on this subject. Every article we read had slightly different opinions and ideas on this. Some believed that the space-time is so warped that no knows laws of physics apply. On the other hand, others believe that if you figure in the gravitational field, and rotation that the laws still work, just differently because of the environment. Either way this is all just theory and speculation, so we honestly have no idea. WHAT?!?!?!? Its okay. We don't get it either. QUIZ 1. Define 2 of these vocabulary words:
Event Horizon
Gravitational field
Singularity 2. In complete sentences, explain the "Noodle Process". 3. Do basic laws of physics apply when in an area affected by a Black Hole?
A. Yes
B. No
c. Unknown 4. Will our sun become a black hole?
A. Yes
B. No
C. Unknown 4. (part 2) Give a brief explanation as to why or why not. 5. What are the 2 kinds of Black Holes?
A. Black Monsters and Baby Devils
B. Stellar-Mass and Intermediate
C. Stellar-Mass and Supermassive
D. Supermassive and Intermediate
