Just because the stuff farther out is moving faster than the stuff nearer the center does not necessarily mean that the Universe is expanding faster and faster. If you set off a firecracker in the middle of a bunch of deer, the fastest ones will be farther from the center at any point in time even if their individual speed is constant.
Black holes are spheres in space, and not the funnel shaped objects so often depicted in science fiction. They are defined by the speed of particles traveling towards their core. But they are controlled by the rate of change in that speed. The force of gravity can be expressed in kilometers per second per second. The creation and destruction of black holes can be understood in terms of a pendulum. When the inward force of a black hole is at its maximum, the pendulum is in mid-swing going in one direction. As a visible object approaches the mid-point, it reaches a speed that exceeds the speed of light and becomes a black hole. As it moves past that mid-point, it begins slowing down again. When its speed drops below that of the speed of light it becomes visible again and is no longer a black hole. Do black holes exist in our sub-atomic world and, if so, how do we detect them?
My Tablet-PC kept overheating and crashing. I found I could fix it temporarily by putting it in the refrigerator for a while. Finally, I used the vacuum cleaner to suck out all the dust from inside. Watch out! Don't use a big vacuum on the keys as they will get sucked up into the vacuum.
Stars operate in a yoyo fashion where a super nova represents one extreme and an almost infinitely dense black hole the other extreme. This could also be thought of as a pendulum with super nova and ultimately dense black hole as the two ends of the pendulum motion. Thus the matter of stars is neither created nor destroyed but just alternating between density levels.
Lawrence C. Marsh is Professor Emeritus (retired) from the Department of Economics and Econometrics at the University of Notre Dame where he taught economics (mainly econometrics) for 30 years starting in 1975.
For 13 of those years he was Director of the Ph.D. Program in Economics where he oversaw the work of several hundred doctoral students in economics and served on 80 Ph.D. dissertation committees. In 1991 he won the James A. Burns award for excellence in graduate teaching and was an O'Malley Award Nominee for undergraduate teaching in 1996. In 2003 he was selected as a Faculty Teaching Fellow for excellence in teaching.
He has given over 3,000 lectures in graduate and undergraduate statistics and econometrics. He has a wide variety of professional publications (see http://www.nd.edu/~lmarsh for details). He has served on a number of journal editorial boards and as a guest editor for the Journal of Econometrics. He has also published numerous monographs, book chapters, and books of which the latest is Spline Regression Models. In 1991 he co-founded the Midwest Econometrics Group (MEG) along with Pravin K. Trivedi and Peter J. Schmidt and served as its director/coordinator for 15 years. MEG consists of almost 600 econometricians from all around the world and holds an annual meeting somewhere in the midwest of the United States each fall at a university or federal reserve bank.
After retiring he worked with an internet startup for just over one year as statistical design strategist responsible for user targeting in sending billions of banner ads over the internet. The CEO was 25 (he started the business at 17). Marsh worked from 4:30 am to 5:30 pm (13 hours a day). There was free soda and treats (gummy bears) and free beer after 5:30 pm (inducement to stay longer). Almost everyone else was under 30. He says “They were all wonderful. Everyone worked hard. It was great fun!” After serving in the Adjutant General's Office at Headquarters & Headquarters Company at Cam Ranh Bay for the US Army in Vietnam, he returned home and joined Bendix Aerospace to work as Subcontract Administrator and Contract Personnel Administrator on the Apollo Missions, the Earth Resources Technology Satellite (ERTS later known as LandSat), and classified military projects. He is now retired and interested in the economics of globalization. He has joined facebook, myspace, hi5, twitter, linkedin and a host of similar internet networking sites.
