This is a comment I found in one online article about the universe. If your online skills are really good, you should be able to track it. Anyone up to the challenge?petrocrab wrote:
"Interesting that quasars and blazars likely are the same phenomenon. I remember when quasars were first discovered (yes, I am a living fossil). They were the farthest observable objects in the known 
universe; thus, they were ranked among the oldest cosmic features.
If quasars and blazars really are the same, I wonder if that might be a clue about the way in which the universe is formed. It seems to me that blazars and quasars may be evidence of a continuum of mini-big bangs, in an open-ended time line.
Maybe there was no single Big Bang. Maybe the Cosmic Party has always been going on, and maybe it always will. "
There is new information coming up everyday about the universe. Amazing!!! Just today there was this video in the front page of Yahoo about some physicists in Switzerland who are trying to recreate the conditions of the Big Bang.
Susana recommended this video (you need a really really fast connection, though, and it lasts 7:44 min.) She also mentioned this interactive page on black holes (let´s see if you can find one mentioned in our quiz). Kelwin suggested another page on black holes, full of key information and having a very nine glossary of terms, which is entitled "Beyond Einstein", quite interesting since it seems we will reach a moment where his ideas on physics, especially relativity, will become outdated, can you believe that?
Cesar V. just shared this 23 second video about a quasar. I wonder what happened in second number 12 ... And Edgard this one about an exploding star.

Hi Berta and everybody!
I'm Lorena from Argentina. It is really interesting the blog you have here. I love these topics, even though I don't study the universe. I've always been keen on it.
Of course, I didn't have a clue about quasars and blazars! But it is always nice to learn.
Thanks for sharing! See you soon,
Lore
Thanks, Lorena, for stopping by.
Yes, we surely learn a lot about the universe in this course while we practice reading skills, acquire new vocabulary and imrpove our English.
All the best,
Berta
Hi Berta!
Encontre un video interesante que muestra informacion sobre los "Quasars".

Hi!
El primer artículo se refiere a la posibilidad de que los quasars sean "mini big bangs", de tal modo que el origen del universo no fue una sola explosión, sino que fueron múltiples explosiones, las cuales continúan y probablemente seguirán ocurriendo.
En el video puede observarse un acelerador de partículas, con el cual los científicos están tratando de inducir colisiones entre las mismas, con el objeto de recrear las condiciones bajo las cuales ocurrió el Big Bang.
Hola a todos, miren lo que encontre http://universe.nasa.gov/science/blackhole.html me imagino que mucho de lo que dicen en esta lectura se les hará ya conocido. Por ejemplo: "Black holes are objects with such immense gravity concentrated in such a small volume that nothing, not even light, can escape their grasp", "event horizon", ahi tienen el link para que la revisen.
En este artículo es interesante destacar la posibilidad de que la teoría de la creación del universo, mejor conocida como la teoría del Big Ban, no fuera en su plenitud factible. Ya que pueden haber evidencias tales como los dinosaurios y los "quasars" que contradigan el hecho de una gran explosión y de cabida a pensar en una sucesión de "mini- big bans" o "mini- explosiones"; cuyo efecto pudo dar origen al universo.
Es una de las tantas dudas que engloban la búsqueda de una explicación acerca de nuestra creación, que hasta ahora, no se han hallado respuestas precisas pero que si bien, las alternativas que se plantean no dejan de ser realmente enigmáticas.
Hi again!
this is the link from an interactive page about black holes hope you like it!

Hi Susana, Noe, Kelwin and Karen,
The idea of having mini big bangs is certainly an original one. This way there will be constant creation all the time. Who knows what the real answer is ... as we have seen, there are new tools created each year and satellites that go further into space that will bring us more evidence to support or reject current theories.
The links Kelwin and Susana were so good that I will post them to the post.
Thanks for sharing.
hola a todos!
buscando información acerca de la diferencia entre los quasars y los blazars leí en un artículo que los radio-loud quasars pueden ser lo mismo que los blazars y que las diferencias que puedan existir entre ellos estarán relacionadas con el ángulo en que se observen los mismos, es decir que un radio-loud quasars son blazars vistos desde un lado.
A mi una cosa que me llamo atención de los quasars y mi lectura, era que los mismos son agujeros blancos, es decir que tal vez esa materia que se esta generando pueda ser de otros universos paralelos, y sería muy interesante saber donde va la materia cuando entra en los hoyos negros. Sin embargo,hasta que un atrevido astronauta no llegue a atravesar un hoyo negro , no sabremos que sucede en realidad en estos cuerpos misteriosos del universo.
hola a todos, aqui les pongo el link de un video muy bueno q encontre sobre los quasars espero que les guste

Ma. Alejandra, Ma. Angélica and César V. (are there two Cesars?),
Yes, I also read that depending on the position of the jet, they can be blazars or quasars, Ma. Alejandra. I also notices, Ma. Angélica in the reading of bizarre aspects of black holes that quasars can be mysteriously formed by going through the funnel into another parallel universe ... it sounds like science fiction, doesn´t it? But many things that were seen as science fiction many years or decades ago are now reality. Scary, isn´t it?
Cesar V., thanks for the video. I placed it in the main post. Short but good. Is it a simulation or a real observation, what do you think?
Todos estos videos y paginas son super interesantes y ayudan mucho a la comprencsion de los textos en clase, los quazars y los blazars me parecen un tema q capta nuestra atencion y todo es mejor con tantos videos y paginas deonde podemos aprender d una manera mas dinamica y entretenida
Goodnight to all
I find it very interesting the part that says the cuasars are the most distant observable objects in the universe. On the other hand is also very disturbing to know that cuasars and blazars may have been the beginning of a continuous process of mini-big bans in an open line of time.This article we really provides information very good and important
Hi Everybody!!
Bueno en este articulo se ve reflejado una vez mas, las diferentes dudas y teorias que existen, con respecto al origen del universo. El Big Bang, los quasars, los "Mini Big Bangs" son todas hipotesis no sabemos si algun dia podran terminar de ser catalogadas como hechos verdaderos.
hi! is wonderful to think that inthe universe continue to happen mini-big bang because if that trust then the scientifics will be able to study this phenomenon and can undrstand what happened in the big bang. I think also that is wonderful that exist in the universe the black holes that have inmense quantity of gravity and more wonderful is to imagine that we can pass through of them and can arrive to other galaxy but we now that anything that enter inside them it couldn't leave.
Me gusta la idea que nos refleja este artículo ya que sugiere la posibilidad de que el universo no se halla formado por una sola explosión, sino mas bien a partir de varios mini big bangs, y que además se sigan dando.
Hi Brickel, Brenda, José Rafael P., Solange and Tony,
All these theories are really surprising as is the work of the many astronomers and cosmologists who try to find more and more pieces of the huge puzzle which is the creation of the universe and all the celestial bodies.
Maybe ten years from now you will smile at all this information which will be rather old by then and perhaps there will be more solid facts to support the big bang, the mini bangs or maybe a brandnew theory.
