Alien's

Just like I dont know if the Big Bang Thoery is entirely correct, I dont know if I believe in alien's. Its hard to imagine anything or anyone on another planet being alive other than us on earth. But scientist have found evidence to prove that there may be life on other planets or that there once was life on other planets. But the stories you hear about people spotting flying disks and seeing aliens doesnt make me believe in them. I think the only way I would ever believe in alien's is if I ever see one with my own eyes.

The Big Bang

I dont know if I believe in the big bang and the whole theory of the earth exploding into what it is now in less than a second. I dont think it is physically possible for the earth to form just like that. And I dont really think religion has anything to do with how the earth formed. Religion wasnt founded or invented until after the earth was here, so I dont know how religion would have anything to do with the forming of the earth.
I believe the earth was somehow put here, but i dont know how. Just like I dont know if I believe the whole Adam and Eve theory and how they were put on this earth, I really dont know how the earth could have just appeared in less than a second. I dont think it is possible.

Variability-
-Does the variability depend on a sample size?
As a sample size increases, range decreases, which means the variability decreases. At first, results rapidly become less variable, then the rate at which results become less variable slows down. As a larger and larger sample, variability keeps decreasing, but very slowly. The slow loss of variability continues until variability is zero at full size.

The galaxy images in the HDF's represent an earlier period in the history of the universe.

Billions and billions of galaxies populate the universe. The Hubble Space Telescope has unmasked many of them in two of the clearest, most distant views ever obtained, called the Hubble "Deep Fields" (HDF's). One view peers northward and the other peers southward.
Scientists have used math to unlock many galactic secrets hidden in these two views.

The Hubble Deep Field North is one of the deepest, sharpest, multi-color images of the faintest universe in visible light. The image was made by aiming the Hubble Space Telescope at one seemingly empty point in the northern sky near the Big Dipper for 10 days in December 1995. About a thousand never-before-seen galaxies are visible in this view of the universe.

The Hubble Space Telescope captured a dazzling assortment of never-before-seen galaxies. The Hubble Deep Field South complements the original Hubble Deep Field taken in late 1995. The constellation Tucana can only be viewed from the southern hemisphere. The 10-day-long observation doubled the number of far-flung galaxies available.

Annie Cannon and her spectra

If I could spend the rest of my life doing anything, I would help other people. If i could be a doctor, dentist, psycholigist, etc., I would. I like helping people and knowing I made an impact on their lives. I want them to know that I care about them and I would want them to know that I want them to be able to achieve anything they set their minds to. Plus I would go down in history as the only person that was able to be all those things in one! :D

Black Holes

1. Distinguishes between an event horizon and an accretion zone of a black hole:
An accretion zone has matter that lingers close to the black hole and spirals inward to form the black hole. Gas and dust particle collide with each other and spin around the hole. An event horizon is a hole that traps things in it forever. Light, dust and other things that get trapped in it can never escape. The event horizon is the imaginary sphere around the black hole.

2. Defines escape velocity, black hole, and the speed of light.
-Speed of Light: The speed of light is a constant in empty space.
-Escape Velocity- Velocity that an object needs to escape the gravitational well of a more massive object.
-Black Hole: An object so dense that light cannot escape from it.

3. Explains the relationship between escape velocity, black hole, and the speed of light.
The event horizon is an imaginary sphere around the black hole where the escape velocity is greater than the speed of light. Once anything crosses the event horizon, nothing, not even light, can escape. When material crosses the event horizon, the mass of the black hole increases, which boosts the black hole's gravitational force and expands its event horizon — the point of no return.

4. Identifies more than one single type of black hole.
Event Horizon and Escape Velocity

5. List evidence that our understanding of black holes has changed.
Miniature black holes might have been created during the Big Bang Theory. The miniature black holes have event horizons as small as the width of an atomic particle. Between 10 and 20 billion years ago, all matter and energy was compressed into a single point. Then this tiny point exploded (the Big Bang) and expanded rapidly.

6. Explain how Hubble Space Telescope's component cameras assist in the search for black holes.
Hubble is a telescope that orbits Earth. Its position above the atmosphere, which distorts and blocks the light that reaches our planet, gives it a view of the universe that typically far surpasses that of ground-based telescopes.

7. List at least 2 myths about black holes that are discredited.
-The volume of a black hole approaches zero. As volume decreases, density increases. Density is the relationship of mass per unit of volume (Density = Mass/Volume). The density of a black hole affects the escape velocity of an object — even light.
- Black holes have a broad range of masses — from the smallest (miniature) to the largest (supermassive).

The Ghost Particle

1. What is a neutrino and how was it first proposed?
-A neutrino particle travels close to the speed of light, lacks an electric charge, are able to pass through ordinary matter almost undisturbed and are thus extremely difficult to detect.
2. Evidence:


3.What does radioactivity have to do with the sun?

4. What did John Bahcall do?
-He is best known for his contributions to the solar neutrino problem and the development of the Hubble Space Telescope.


5. Ray Davis was trying to create an experiment where neutrinos changed chlorine to argon atoms. Where was his setup located?

Killer Solar Flares

I dont think in 2012, we are going to have "Killer Solar Flares" that cause the earth to explode, and all the people living on the earth to die. Just because the Aztecs calendar doesnt go pass 2012, doesnt mean the world's going to stop. Everyone thought the world was going to end in 2000 after the millenium, but nothing happened. I think its the same with the world ending in 2012. Its just a myth.
