Please explain why are quasars located so far away. Also the concept of objects in earlier space?

Question

The deeper we look, the older stars are, of course, light travels greater distance, but aren´t quasars the same age considering they were born with the big bang along with other galaxies??, I cannot understand this concept about earlier universe in its present state.

Answer 1

Quasars are not yet fully understood. One reason they're far from us is that we're lucky: if they were closer, the immense amounts of energy they produce would turn the earth into a cinder.

Answer 2

Quasars are NEARLY as old as the universe is - they are the first stars that had formed themselves in the young, but expanding universe. So these Quasars are meant to be near the universe's end - so the opinion of an endless universe was formed.
We know their age from very difficult measures, the oldest one is - if I remember correctly - about 15 billion years old - 1/2 billion years younger than the universe.
And because the Quasars still move on, we imagine that the universe still expands.
Nowadays some scientists think that they solved another piece by solving the mess around the big bang. They made anti-materials (only some atoms) - with nothing more than two high-energy lasers. So they concluded that the big bang might have happened the same way - some high-energy radiations might have collided. But this time normal materials werde formed. They were such a lot that they later could form every material in our universe: stars, planets, asteroids, moons, fogs etc.
But because the big bang was a great explosion, everything was "thrown away" from the centre - and there is nothing that could have braked them.

Answer 3

They Formed Say Half Billion Yrs after The Big Bang. So try this Paradox, If We R Say 10 Billion Yrs From It, And The Universe expanded In all directions, Then Opp To Us at The Other end Of The Quasar Is another Galsaxy Also 10 Billion Light Yrs Awy. So The Total Dist Bet us and The Galxy On The Other side Happens To Be 20 Billion Yrs. But The Universe is only 13.7 Billion Yrs Old.What Is Goin On? Only God Knows

Answer 4

The farther out in space you look, the further back in time you are looking. So if something is 4 billion light-years away, you are seeing it as it was 4 billion years ago (because it took 4 billion years for the light to travel to Earth). Almost all quasars are found very far away from us, on the order of 10 billion light-years (the Universe is 13.7 billion years old, so we can't see anything farther away than 13.7 light-years). This implies that quasars only existed in the early universe. What happened to them? They calmed down and became regular galaxies. Scientists believe that when galaxies formed (shortly after the Big Bang) they were all very violent places, emitting lots of radiation. Over time, they calmed down. So nearby galaxies tend to be normal, far away galaxies tend to be active.

Answer 5

There is no particular reason for which Quasars are located far away, they just are. Like we are located in some area of the Milky way. Now as everyone explained the further you look into space, the older the things you're looking at are. Quasars are known to be several billion light-years away so we are seeing them when they were quite young. Now something everyone forgot to mention which is very important is why are they so bright? The reason they are so bright is that like any other galaxy their center is a super massive black hole. This black hole like ours and alot of other galaxies had a phase where it was absorbing everything it could get. Now for the Milky way, the black hole is dormant because it has eaten up everything it can. But, for a younger galaxy, it would still be eating.

The conclusion: since quasars are very young, their black holes are still eating. Since their black holes are still eating, they are still emitting very energetic light (gamma rays). Since they are very far away, their light is very red shifted therefore emitting in visible light which is why they are so bright. Quasars are really interesting.

Answer 6

"...I cannot understand this concept about earlier universe in its present state..."

I'm not real sure I understand what you're looking for, but in terms of the 'earlier universe in its present state,' remember that we can not examine the universe in its present state because of the vast distances involved. We look at quasars not as they are NOW, but as they were tens of billions of years ago. During those billions of years those quasars have receded untold billions of light years due to the expansion of the universe. What were quasars are today probably unremarkable, quiet galaxies.

Answer 7

Quasars were not born with the universe, they are stars and stars were formed well after the big bang.

Answer 8

A telescope and digicam are used. The scope gathers an outstanding style of sunshine right into a small kit deal and makes the gadgets brighter. It also makes the item look better. The digicam is like your digital digicam that you are able to take images of issues the following. It has a really sensitve patch of digital squares that takes the gentle and ameliorations it to electric powered alerts, only about like tiny photo voltaic panels. Tiny squares of the patch are talked about as pixels. those are only like those on a visual exhibit unit or flat television exhibit screen. they are practice in rows like college desks to make into the images. the colors are a lot brighter and deeper than you may see consisting of your eye in case you've been way out in area, close to the gadgets. this replace is carried out in a workstation software. It makes the gadgets look better exciting or alluring. Scientists can degree diverse colors to inform what the gadgets are made up of.
