Hubble depth field


During the activity I learned a bunch of different things. It was interesting to see the size difference and what we think that it is and what it actually is. To me looking at the pictures they look really tiny and reality they are pretty big.
In one of the things the sample did was to take photos and i choose to take 22. The results that i got were, ellipitical: Frequency: 3, %: 13.6, spiral: Frequency: 6, % 27.3, irregular: Frequency: 13, % 59.1. With those results it showed me how close i was to the actual.
This activity was neat to see how the sizes and scuh varied and to be able to guess and to know weather i was right or wrong. Trail and error and then to see how it really worked. It shows me a lot about the galxies. I had no idea about that you could be looking at something in the sky that looks exactly the same when really they are two totally different things in the sky that are just close to each other.

BIG BANG!!

I can agree with the BIG BANG theory that it is possible to happen. Because it happened over a long enough period of time. With all of the things that happened within the big bang and with the religion part of what they think has happened. With the whole let there be light and there is light is like the light was the God and he is the one you should follow and live your life for. The religion and the big bang are very similar and are almost the same just the way they think it happened seems to be different. That God did everything and that's is why it happened and the big bang just kinda happened and not have specific reasons why.

are there aliens....

I'm not sure what to think weather or not there is aliens out there. Part of me thinks that there is a possiblity for anything to happen and be out there. On the other it doesn't seem likely that there is aliens out there. But our world and space is sooo big that i don't think that we are able to see everything everywhere and what is going on. In our world today a lot us think that we are the only "creatures" out there and that there really isn't any possiblity for other life forms out there.

black holes

event horizon everything that goes in the middle will be there forever and never ever ever come back Accretion disk things that hang out close to the black hole will spin towards and form an accretion diskBlack hole is an object typically a collapsed star whose gravity is so strong that its velocity escape exceeds the speed of light. Since nothing is known to exceed the speed of light, nothing can escape from a black hole Stellar Black holes made from stars Supermassive Black hole superfast moving gas jet Miniature Black holes no evidence but may have happened earlier
Hubble Space telescope, Stephen Hawking, Albert Einstein and Karl Schwarzchild Simon Pierre LaPlace WFPC2 records sharp images of very distant things FOC records images of faint celestial objects STIS separates starlights into its component colors Volumes of black holes are huge and black holes have no mass
