University Guide

I have decided to research the different universities that offer Physics degrees and Physics related degrees. The mission statement is to give prospective high-school/secondary school students the opportunity to properly research the University that suits them best. I will be covering modules that they cover. Reviews of the university, not from newspapers or on-line websites but from the people that matter. The students & graduates that came from these universities. I will be including a ranking system( perhaps a crude one) where I will have the top 10 Universities for Physics in the US, UK and Asia. I will have a Ranking system for the 20 Best Universities in the World and have a list on what topics best suits these universities. For example, the university of South Hampton would be know for Black Hole research in the UK and in Caltech and so on. Just to note that this is actually for me as-well as the reader as I am generally interested in which Universities offer the best courses  for the student. I know most students will not know what field they would like to be in in Physics, but some do or at least have a general ideal. Some might want to be in fluid dynamics, some in Astronomy and others in particle physics. This guide is for them essentially, but this can be used by others to ascertain which universities would be best for physics and which will suit them. As to avoid hefty financial mistakes. I will be inserting college fees to each university rank, if and when I can find them. I will ofcorse have links to their respective pages so you can obviously clarify yourselves from more official sources. It is essentially, to allow you the view to find out which universities you should be looking at and also where some of the great scientists or our time and before then have studied and come to greatness.



Just to mention, that some of the information at time of print will be in date, but I might or might not update it. I will see how things go, If I can get a chance to do it, I will. You can always contact me if you have any questions on the matter.

This will come in time and will be a building process.

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.
