That would be a lot of matter and therefore would be generating a lot of energy. Start here for a quick overview of the site A quasar is a whole galaxy that shoots out a beam of energy from its north and south poles.

This remarkable achievement showed that 3C273 has structure in its core at least as small as 26 microarcseconds across.
What you see is what was before.

When the signals it receives from a distant quasar are combined with simultaneous data acquired by its earth-based partners at Arecibo in Puerto Rico, Green Bank in West Virginia, Socorro in New Mexico, and Bonn in Germany, the observations simulate a dish up to 350,000 km in diameter.

Quasars are bright because the light, which shoots out of black holes perpendicular to the black hole's plane, is concentrated into a very small (relatively) beam. We perceive the Sun as extremely Luminous, but in comparison, Quasars typically … Amazon, the Amazon logo, AmazonSupply, and the AmazonSupply logo are registered trademarks of Amazon.com, Inc. or its affiliates.” The smaller the angular diameter of the object producing the radio signals, the higher its source temperature must be to produce the observed signal. It appears that the "sweet spot" for comparatively short-lived phases of "quasar activity" is at redshifts of 2-3 where there was significant merger activity and the transport of gas into the central regions of galaxies, but that there had been insufficient time to fully exhaust the gas in galaxies with central black holes.in the early universe there was more diffuse matter in gaseous form available to the black holes. A: they are white hole where matter enters the universe and the are bright because the rapid entrance. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions.Solve this simple math problem and enter the result. Why are all quasars so far away?

Radio astronomers measure the apparent brightness of objects such as quasars in terms of the temperature a solid body subtending the same angular size would have to possess in order to shine with the same intensity.

A quasar is powered by a supermassive black hole. E.g. However, one of the most obvious objections to this was that we Thus this observation tells us that the characteristics of the universe are changing with time and therefore that the The more limited Cosmological Principle meanwhile remains. It only takes a minute to sign up.If the universe is homogeneous, we could expect to have a homogeneous distribution of quasars, but all of then seem to be far away from Earth.

The ability to see such detail is not matched by any other telescope in the world.

Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located.

So imagine a disc from a point about 1/4 the way to Mercury out to the orbit of the Earth. In fact, most quasars are so bright, they outshine their host galaxy by a large factor.
After they vacuum clean their environment, they calm down and the quasars basically turn off.There are essentially no quasars forming in our time.

The best answers are voted up and rise to the top Optical telescopes, even the Hubble Space Telescope, do not come anywhere near this ability to see detailed structure. Here’s a great Quasars are generally thought to be the result of galaxies and their two black holes colliding together. $\begingroup$ You suggest that our region of space coincidentally happens to have fewer quasars and so is more hospitable to life.

Olber's paradox cannot be explained by a Steady state theory is of course contradicted by many things, including the topic of my answer. Why is that?The discussion of the Cosmological Principle above is very relevant, but it is possible that so is a (weak) application of the anthropic principle - in other words if we were in a region of extremely energetic physical phenomena, such as quasars, we would be unlikely to exist - as the evidence suggests that the development of intelligent life takes a considerable time and highly energetic events are likely to disrupt that.First, quasars are rare objects, so even though they are homogenously distributed on large scales, the average distance is large. Because quasars are so bright, they drown out the light from all the other stars in the same galaxy.
