Is there life in other planets?

When looking at Google about life in other planets than the planet Earth we find out that there is a high possibility that there is life in planets like Mars or Saturn where salty liquid oceans are found.
This point is enforced by saying that if microbes can live in many different environments with different climates and temperatures there is a strong possibility that they could live in other planets.
A web page named Universe Today says that;
 “A lot of information can be gained by analyzing the surface composition for the materials required by life (as we know it) to survive.”
This shows how different spaceships and different machines are landing in Mars (like THE PHEONIX) to investigate and gain information about the subject.
Some digital newspaper’s talk about this discovery and give some information about the happening.
A heading of TIME talks about “The Salty Waters of Saturn's Moon Hint at Life” and how “in recent years, scientists have come to learn that by some measures, the solar system fairly sloshes with water. Mars, we now know, was once as wet as Earth and still harbors ice and perhaps liquid water.”
We also find out that there could be life at Mars because they have the same seasons and similar climates and weathers. Also there could be existing life because Mars is composed by Carbon and Nitrogen, this elements are essential for having living animals or life.

Google bombing:


BBC News 
Wednesday, 13 March, 2002, 11:05 GMT
"Google hit by link bombers
Popular search site Google is being exploited by some net users to mount protests and play jokes on their friends.
The users have found a way to "bomb" Google to improve the rankings of particular webpages, and ensure a site is near the top of the results for particular search phrases.
Google screen grab, GoogleBefore now Google's method of ranking webpages was thought to make it largely immune to the tactics that many businesses use to improve their position in web searches.
Some fear it is only a matter of time before businesses start using the bombing tactic to influence their standing in search results."






In this quotation is important to remark the danger of Google bombing this can hurt people, individuals, and also companies. 
An example of Google bombing is the next;
French military victories (http://www.google.com/search?q=french+military+victories&btnI) - hoax, Google look-a-like page saying "no results found for French military victories, did you mean French military defeats?"

'Miserable failure' links to Bush

George W Bush pauses during a press conference with Tony Blair in London
Bush has been the target of similar pranks before
George W Bush has been Google bombed.Web users entering the words "miserable failure" into the popular search engine are directed to the biography of the president on the White House website.


 In this article we can see how Google bombing can have political purposes and also expresses the different comedic purposes this has. In my opinion google bombing is a method of violence we Google users have and how a simple joke or prank can be enlarged like in the snow-ball effect by the press.
 http://www.digitaljournal.com/article/302725
The digital journal talks about  how the use of Google information (public / virtual information) in bad hands can be a terrible and strong weapon. "if put to malicious use against someone, it can be a paralyzing weapon".
I agree with what this digital journal says because google bombing is a very important issue and it can hurt lots of people.

1) A. We can see that the crawlers of this search engines find data that is constantly being updated (frequency). Also that the web pages crawled by the search engine have their full length untouchable and also its depth (this can be stated by showing that the different branches of links are untouched). 
In Google we can see that there are jpg1 and jif when in Bing this isn’t found. While in Bing we can see images at the web pages but no videos.

B. In Google we can see that this search engine has an arrangement with Wikipedia by putting its information at the beginning and then the other web pages. In the case of Bing it’s notable that this search engine copies the results from Google. When looking at the other 3 results in both search engines we can observe the same web pages; Wikipedia, electriccars and tesla motors. This also shows how Bing copies Google results demonstrating why Google accuses this firm of replicating their results.
Google results are ranked in this way because of different financial agreements. In the case of Tesla motors it’s very common this firm pays Google a certain amount of money to be in the front page and well ranked also the Meta tags of this page may concord with the search “Electric cars”. At “www.electriccars.com” we can find the same scenario than Tesla motors.  Finally we can perceive that Google is in a way showing it own page images by increasing its popularity and advertise its different uses. In the case of bing we can notice that Microsoft has an arrangement with facebook and that’s why it appears in the front page, and also if watching it with a different point of view (POV) the meta tag  could also have something to do (Is the same as the search “eve electric cars”).

C. In conclusion both Santos and I could observe the different arrangements each search engine has with different companies or firms. Also the ranking algorithms work in a certain way so that the web page with a common meta tag as the one that is searched by a user or common information appears in the front page. Also Google in the example of the images tries to promote itself by different ways and making the consumer exploit the different uses this web page has.


3) In this different search we could observe that google bombing is to use the ranking results at this search engines by using different meta tags in order to communicate a message which could be either business, political or comedic purposes. This has different effects on individuals and/ or organisations this differs  from the message that is tryig to be shown to the user. In the case of the search "miserable failure" the ex president of the united states Bush is being discriminated. (has a political and comedic purpuse). In conclusion we could see that google bombing is an actual problem of discrimination and segregation that has to be stopped this is because it harms firms and individuals and has no good end (encourages violency).

1st Statement:

“When a person excrete, a computer can analyze it and it

can tell what you have inside”

The statement below demonstrates that the statement above is not true.

The introduction of new medical technology has not been so rapid in developing countries, but the sense of ambivalence is the same – technology represents both progress and threat. In countries with multiple healing systems patients can choose whom to consult, depending on their illness. In these countries a technological approach may be chosen as a first or last resort. 


2nd Statement:

That a person can travel through the universe in less

than 10 minutes”

First of all it is necessary an impossible amount of

energy to travel as fast as speed of light and if this can

be achieved in the future (it is nearly impossible) the

human body wont resist it. (If the person reaches this

velocity its mass will be transform in energy, and it will

be capable of travelling in time.) 


No we cannot. No matter how close you are to the speed

of light if you have all the thrust in the universe you

cannot get going past the speed of light. "The famailar

notions of absolute space and absolute time

independent of your relative motion must give way." -

Carl Sagan. There is a nice thing that happens though.

As you mentioned time slows down when you approach

the speed of light. This is because atomic particles dont

decay as quickly near the speed of light.
