How Are Black Holes?

Cosmic black holes – giant in the space black holes are environments in the universe, where the gravitational force is so strong, that it not even light can escape. Learn more at: Cancer Research. But how are these extreme objects? Black holes are remnants of stars. When a very massive star has used up its fuel supply, it inflates and finally ends in a huge explosion: the supernova. Enormous result in the Interior of the star pressures and temperatures. The matter in the core of the star is so heavily compacted that she collapse under their own weight.

This material is then concentrated in a point of unimaginable high density – a black hole is formed. White dwarfs and neutron stars, not every star ends up as a black hole. Our Sun, for example, is too easy to do so. It will end in a supernova, but as a white dwarf. This is, simply put, what remains when the star has rejected its outer hull: the core of the star, a hot only moderately Ball of carbon from about the size of Earth.

A star has about the triple mass of our Sun, it no longer ends white dwarf as a neutron star: A in diameter approximately 10 kilometers high ball consisting of very tightly adjacent packed neutrons. Once a star about the eightfold mass has our Sun or more, it can end as a black hole. The incredible interior of black holes it is difficult to describe, what happens inside a black hole. How do behave there time and space? Is a good forum for this physics scientific basis is needed to share new knowledge and information in this regard. A physics Forum will help to promote communication in areas, whose research facilities scattered around the world, include in particular the Astrophysics and astronomy, but also the space itself. Today’s physics know 2 great theories: operations on a macroscopic scale are described with Einstein’s general theory of relativity, this is the area of cosmology. You would like to investigate the world in the little ones, however, it refers to the micro-cosmos, quantum mechanics. But which of these two theories take, when one considers black holes? On the one hand, it would take the general theory of relativity because a black hole is a cosmological object with immense mass. On the other hand the quantum mechanics, since the mass of the black hole on an unimaginably small area is focused. What to do? Desirable, a theory, the theory of relativity and the quantum in nature would be United. There is an approach to: string theory. This still the infant theory one day could bring light into the darkness of black holes.

New Display Options Thanks To Microscopy

The microscopy makes it possible to look at very small objects or structures, and to investigate. The microscopy makes it possible to look at very small objects or structures, and to investigate. In biology, medicine or material sciences, microscopes are important tools for all the things that the human eye can not perceive. The PCE Germany GmbH opens the page of microscopy, a new section of the laboratory technology. The page contains all kinds of microscopes in different areas. When you consider how much benefit has pulled the medicine by microscopy alone. The evaluation of micro-organisms, tissue, cells and blood components are indispensable for mankind. Many findings would not exist today and progress had not evolved.

The physical principles are exploited for the magnifying effect and you can be very different. Before something under the microscope, there are certain processing procedures such as cuts and color techniques, better represent the cell structures can. The oldest and best known technique is the light microscopy, in which an object is considered by one or more glass lenses. This microscopy the microscope produces a magnified, inverted and real intermediate image using the lens for the time being. Then this increases intermediate image again using the eyepiece through which you look. The total magnification is calculated from the magnification of the objective and eyepiece.

For very small objects using an immersion objective, on the one oil carries on a droplet, fills as the space between the lens and the object, and optimizes the resolution. In this way objects can be visualized up to 200nm. Of course, there are also in the microscopy USB microscopes to the live”representation or documentation on your computer. The PCE MM 200 for example displays crisp sharp images of up to 200 x magnification on a computer screen. More information under: labortechnik/mikroskopie.htm
