Aliens

I think it would be sweet if there were other life forms out there!!! WE could communicate and maybe they could help us clean up our earth so we don't kill it and us together!!! It may be possible to find life out there, considering we can't and haven't gone to any other galaxies. I think if there is a way to get to another galaxy faster then we may be able to find life out there. But..if they have the same intelligence as us then they would have been able to find us already. SO i think we should create some type of thing to get us to another galaxy to see what we can find. We may be able to communicate with other life forms..which would be cool.

Big Bang

The Big Bang Theory is a theory that the universe was a small particle that exploded and made the universe. We have been studying the universe for many years and have used different tools to help us. Microwave radiation helped up figure out the steady rate theory by sending waves that interfered with telephone calls. COBE was the first study of microwaves across the universe. WMAP is a thing that shoots off into space so we can study it further and CBI is a big tin can that sits on top of a mountain that we also use to study space. While using WMAP we found out that it traveled all the way past Jupiter. We found out that humans are actually possibly made of stardust. crazy. In conclusion...im not sure if i should believe the big band theory or not.

Stellar Evolution

A.) No, as it cools it becomes a black dwarf.
B.) It's life cycle is almost over..which means it is almost dead.
C.) No it cannot
D.) They are the nearest to the sun, most common type of star in the galaxy, and are strong X-ray sources.
E.) They all go through a cycle.

1. The event horizen is the middle of the hole. once ur there, you're stuck. the accelleration to get away from one has to be faster than the speed of light.
2. The escape velocity has to do with the size of the object and its mass, if the object is small and has a lot of mass, you will need nore velocity to escape it. that also describes a black hole. the speed of light is not enough to escape it.
3. The escape velocity must be very high if the size of the black hole is small with a very high mass. light gets bent if it passes to close to a black hole.
4. Stellar black holes are created by dying stars super massive black holes are in the middle of a galaxy.
5. They thought black holes were invisible stars.
6. Uses the stis to use infrared visible and near ultrviolet light.
7. The volume of a black hole is huge-false
black holes will eventually destroy the universe-false

Rest of my life...

I want to major in psychology... I want to be a therapist for teens.
I think that i can help them in a variety of ways...and i would be really good at it.
I am a really good listener, even though sometimes i have selective hearing..haha
I believe that this would be a great job for me...and i would really enjoy it.
I want to go to the University of Texas in Austin.

will this be the end...?

IM not sure if we should be scared or not. We haven't been hit yet, but this is 26,000 years later... when everything lines up. No one was around to know what happend 26,000 years ago? So i think the world may very well end on December 21, 2012....Thats what i have believed for a long time. It kind of all makes sense, but then again, Ma Powell says it wont. So..i might have to take your word for it!!

Asteroids...be scared or not?

Honestly i think we should be concerned. If we know ahead of time we can get all the people evacuated and away safely! The human race can't end...thats just not a good thing. We could completly avoid the affects of a shoemaker levy 9 asteroid because if we know it's coming, we could possibly destroy it or at least get people to safety. But then again, a football sized asteroid is a threat to the earth every million years...im not sure we could destroy an even bigger asteroid if we can't do anything about that one. Then...the human race would be gone..and...yeah. that would suck.

Pangea-means one land, scientist believe that the continents were once one big land mass
Sea floor spreading- two sea floors are spreading apart makes the ocean bigger.
Plate boundries- the edges of the plates
The ring of fire-where all of the volcanoes are
The mid-ocean ridge-the biggest maountain range in the world, tallest, and it's underground
Shifting north and south pole-north and south pole switch once every 100,000 years don't know why

Extinct volcanoes on the moon tell us that the moon's crust isn't moving
Active volcanoes on mars tell us that the crust is still moving

Dubo-shifts 4.26 mm a year
HILO-35.77mm year
KELY-11.23mm a year
HOFN-14.87 mm a year

Tells us they are slowly moving

Rotation of the earth-caused the earth to wobble slightly on it's axes, also shortened the day by 2.6 micro seconds


Shape of the earth - The momentum of the water displaced by tectonic uplift had also dragged massive slabs of rock, each weighing millions of tons, as far as 10 km (7 mi) across the seabed


Shape of ocean where it originated there was a sudden vertical rise in the sea bed.


Energy released-the same as 26.3 megatons of tnt.

Three pieces of evidence for his idea for plate techtonics
1.The continents fit together like a puzzle
2. Found fossils of animals that couldnot have survived unless the contenents were connected
3. Found fossils of tropical plants in antarctica

The Rest of the Moons

a( Periods of the four moons
b( The graphical pictures attained
c( Difficulty gallileo had seeing it
c( How mini system helped gallileo form heliocentric views
Lo takes 25 days to travel around jupiter, Europa takes 3 days to travel around, Ganymede takes 7 days, and Callisto takes 15 days
Thy graphics, like the wave lengths, show the shape of the orbits, the more symmetric the wavelengths the more circular the orbits are. To gallileo, it would have looked like the moons were just moving back and forth. seeing the moons go around jupiter gave the idea to gallileo that a solar system could revolve around the sun.

Jupiter's Moon

Callistio is the furthest moon from jupiter. We can tell because it has the highest waves and also has a very circular orbit. The way i can tell is because the wave shapes are very even.
Lo is the closest moon to jupiter. We can tell because the wavelengths are very short. It's orbit is not circular because the wavelengths are sparratic.
