Black Holes in Small and Medium

Using data from the Rossi X-Ray Timing Explorer, scientists have found the smallest Black Hole yet identified. It is part of a binary system in galaxy XTE J1650-5000. The Black Hole has 3.8 times the mass of the Sun and would have an event horizon 24 km in diameter. These findings were presented Monday at the AAS High Energy Astrophysics Meeting.

Separately, astronomers have identified a medium-sized Black Hole 17,000 light-years away in the Omega Centauri cluster. This globular cluster, pictured above, contains 10 million stars that are among the youngest in the Universe. Scientists have long wondered how globular clusters formed. Some estimates have them older than the Universe itself! Researchers using the Gemini South and Hubble Space Telescopes conclude that Omega Centauri contains a Black Hole of 40,000 solar masses.

Since globular clusters are so old, this Black Hole could be primordial, formed soon after the Big Bang. We have also found galaxies containing supermassive Black Holes formed when the Universe was less than a billion years old. Size of a primordial Black Hole is limited by a horizon distance related to the speed of light. Massive Black Holes within ancient globular clusters are another indicator that c has changed.

OK brain pan, I followed all ya said till this bit

"Size of a primordial Black Hole is limited by a *horizon distance related to the speed of light.*

Massive Black Holes within ancient globular clusters are *another indicator that the c has changed.*"

Now, please, in dumb dumb terms that The Great Gazoo would use for Fred Flintstone...what the hell are you talking about?!?

Seriously dude!

These primordial Black Holes formed from dense regions that collapsed. Their size is limited by the amount of mass light could reach in a short time. If the speed of light were higher in the past, that would be a lot of mass.

Thank you, I understand now. The imperfections of the surface of space time where the first matter clumped together within the scale (pysical space X,Y,Z) leads to the limiting factor of the first black holes.

Did I get it?

Besides my C course, I have a job and family, both of which compete to get my time. I couldn't find sufficient time for the challenging C assignments, and these people came in and saved my skin. I must commend them for the genius Programming Assignment Help. Their C Homework Help tutors did the best job and got me shining grades.

Matlab Assignment Help helped me to complete my seventh Matlab assignment, which was also the best-performed! It scored 92/100, which I've never scored before on any other assignment/exam in my lifetime. Otherwise, their service was as quick as usual. The delivery was also on time. I'm now requesting to use this same programmer multiple times. He seems the best in Image Processing tasks. Meanwhile, I'll ask for more Matlab Homework Help soon.

I have just come across your post and I believe this is exactly what I am looking for. I want an economics assignment help from a tutor who can guarantee me a top grade. Do you charge per page or does it depend on the
bulk of the economics homework help being completed? More to that if the work is not good enough do you offer free corrections.

Hi, other than economics assignment help are there other subjects that you cover? I am having several assignments one needs an economics homework help expert and the other one needs a financial expert. If you can guarantee quality work on both then I can hire you to complete them. All I am sure of is that I can hire you for the economics one but the finance one I am not sure.

Hey STATA homework help expert, I need to know if you can conduct the Kappa measurement of agreement. This is what is in my assignment. I can only hire someone for statistics assignment help if they are aware of the kappa measurement of agreement. If you can do it, then reply to me with a few lines of what the kappa measure of agreement is. Let me know also how much you charge for statistics homework help in SAS.

The ardent Programming Homework Help tutor that nailed down my project was very passionate. He answered my Python questions with long, self-explanatory solutions that make it easy for any average student to revise. Moreover, he didn't hesitate to answer other questions, too, even though they weren't part of the exam. If all Python Homework Help experts can be like this then they can trend as the best Programming school ever online.

Hey there, I need an Statistics Homework Help expert to help me understand the topic of piecewise regression. In our lectures, the concept seemed very hard, and I could not understand it completely. I need someone who can explain to me in a simpler way that I can understand the topic. he/she should explain to me which is the best model, the best data before the model and how to fit the model using SPSS. If you can deliver quality work then you would be my official Statistics Assignment Help partner.

How much do you charge for a Statistics Assignment Help task? Take, for statistics assignment experts my case, where I need you to provide me with the Statistics Homework Help on plotting a scatter plot with a regression line? How much should that cost? Do you charge on the basis of the workload or have a constant payment?

As much as there are discouragements, it is true that mathematics is hard. Like in my case, I was never discouraged by anyone about math but I still find it very hard and that is why I am requesting your Math assignment help. I am tired of struggling with mathematics and spending sleepless nights trying to solve sums that I still don’t get right. Having gone through your Math homework help, I am sure that I will get the right help through you. Please tell me what I need to be able to hire you.

Just what I was looking for. I am struggling with my accounting assignment. I want an Accounting Assignment Help tutor to offer me two services. One is to complete my accounting assignments and the other is to provide me with online classes. I believe you are experienced enough to offer both Accounting Homework Help and online classes. I know you charge assignments based on the bulk. Tell me how much you charge for the online classes per hour.
