Necessary Ingredients Detected in the Milky Way for the formation Black Holes Pt.II

Now as mentioned before, there is uncertainty  about the implications of the time lag, would that nebula still be the same as it was when the light left that cloud 30,000 years ago. I don’t know. Everything we look at respectively is looking in the past, the light that is coming to our eyes are images of the past. Looking at a computer screen its only a few femtoseconds to reach the screen to your eyes. As you could imagine this is not a really example and shows how insignificant it is. But if you amplify the distance considerably, then your results begin to take form.

The disk shaped clouds that were observed are about 50 light years cross . This is a massive number and in comparison to the Earth, you would not be able to see the Earth, in fact you wouldn’t be able to see the sun, except maybe for a little white dot so faint, that you would mistaken it for a dead pixel on your screen.

The leader of the study Tomoharu Oka of Keio University in Japan stated that the 50 light year across chemical cloud “revolves around the supermassive black hole at a very fast speed". Which the other clouds of clumped chemicals are increase and expanding very fast rates of about 223, 000 mp/h. This is allowing the scientists think that the super novas massive explosions were a cause of this particular expansion.  This is an interesting part, that the fast growth of the cloud is suggesting that 200 super nova have gone of inside. This cloud is assume or suggested to be only about 60,000 years of age (Not very old, relative to the cosmic age). Deducing this from the observations, it is thought that supernovae are suspected to go of every 300 years.

Necessary Ingredients Detected in the Milky Way for the formation Black Holes Pt.I

In certain parts of the Milky Way galaxy habit molecular clouds, these thick and massive clouds of chemicals are good birth places for new stars for which nuclear fusion can commence. Scientists are searching in these regions which contain the most massive and the most densest molecular clouds. These are known to habit and surround our galaxy near the center, which has be suggested that a Super Massive Black Hole is in the centre, dictating our gravitation interaction with the galaxy and everything within it. This Super Massive Black Hole mentioned before in pervious topics, named Sagittarius A* or Sgr A*) is the lynch pin of the galaxy, making everything in and around it form in to a swirl of immense gravitational force.  This Black hole is the suns mass of about 4 millions of our Suns! That’s pretty big and you can imagine the gravitational forces that are associated with this stellar mass.

These clouds that scientists are looking for are good places to start looking for evidence for forming stars. To analyse what is going on in these places, the use of radio telescopes are to determine the make up of these clouds and to compile a map of the density and temperatures of the molecular nebula in the center of the Galaxy. The discovery of 4 massive gas clouds that appear to be the seeds of small medium black holes. These voids in space or ultimate density. 100,000’s time more denser than the Sun are suggested to be the building blocks of SMBH’s that are thought to be in the centre of the galaxy.

Though these clouds are really big, they are 30,000 light years away from Earth. Though we are able to see them now. Why is that?  Well the simple answer is that light travelled to us. I have asked a few times, why if its 30,000 light years and that means that light would take 30,000 years to reach that nebula then another 30,000 light years back, wouldn’t that mean we couldn’t, realistically do anything about it. Light travelled from the nebula 30,000 years ago to reach Earth Today.
