The great adventure of physics now is to find a formulation that combines the two great theories of science: relativity and quantum mechanics. When attempting to unify these theories, the solutions become infinite, ie, they are not renormalizable. From Einstein to Hawking, to Edward Witten, attempts have been futile. Is the superstring theory, a very complex mathematical structure, which gets one. Until you experience with it is achieved, scientists can not give its approval, and it takes so much energy to get it more than likely not be achieved until several centuries.
gravity theories of Newton and Einstein are different. The discrepancies between theory and observation were resolved and the theory of universal gravitation Newton was accepted until replaced in 1915 by the theory of general relativity of Einstein, which is consistent with that of Newton in the domain in which all bodies move very slowly compared with the speed of light. In the solar system, planets and satellites travel at speeds of tens of kilometers per second, while the speed of light is about 300,000 kilometers per second. Einsteinian corrections to Newton's theory are thus practically negligible, and can only be detected in a very small number of observations. Einstein's theory has passed all the tests that have been subjected.
Wormholes arise as solutions to the equations of Einstein's general theory of relativity when applied to black holes. Do arise as and easily followed in this context that some theorists are inclined to believe that eventually be found or manufactured counterparts and, perhaps, be used to travel faster than light speed. The theory of wormholes goes back to 1916, shortly after Einstein published his general theory, when Ludwig Flamm, a Viennese physicist known, was set in the simplest way possible and theoretical black hole - black hole Schwarzschild - and discovered that Einstein's equations allow a second solution, now known as a white hole, which is connected to the input of the black hole through a pipe the spacetime. The "entry" of the black hole and "exit" white hole could be in different parts of the universe or in different universes. In 1935, Einstein and Nathan Rosen further explored the theory of connections intra-or inter-universe in a presentation (1) whose purpose was to explain fundamental particles such as electrons, in terms of space-time tunnels by lines of electric force. This led to the formal name Einstein-Rosen bridge which later the physicist John Wheeler would refer to as "wormhole" (he also coined the term "black hole" and "quantum foam").
When we are talking about a "singularity", we are planning a mass with volume zero gravity surrounded by a border called "event horizon" from which nothing can escape. For there to be a black hole, somewhere must have a singularity and, for that to happen, must be enclosed on the outside by an event horizon, which means in essence that can not be seen from the outside the same singularity . Specifically, it means that there is a region unable to send signals to the outside infinity. The boundary of this region is what we call as the event horizon.
If the universe had shore, what would be next?, But first let's look at the meaning of the universe. Universe: The set of all existence. Both large-scale structure of the universe as there are questions about their origin, and possible future developments are considered by cosmology. The universe contains galaxies, clusters of galaxies and larger structures called superclusters of galaxies, black holes, asteroids, comets, meteors, etc .... closed universe models, open and flat, are as main feature of evolution: the universe changes with time. The closed model expands over time from a superdense original point. But unlike the current model, it has enough matter to stop the expansion before it reaches to infinity, that is, the subject released outside loses its speed from the time of the explosion, so that galaxies come to a halt in some instant.
Big Bang theory postulates that the early universe was in a tiny cluster of matter exploded and expanded to anything known in knowable space. All that stuff was eons recombining, merging, transforming with the help of chaos and chance, gradually forming elementary particles and eventually coming to the consolidation of entire galaxies. The infinite combinations likely allowed the conjugation of some blocks of biological molecules that gave the near-miraculous phenomenon of life, become almost zero and rare in this universe, another great evolutionary event allowed the emergence of what is now called "intelligent life" This intelligence has envisaged two destinations: A) The expansion will continue until the energy from that explosion Primal is depleted and slowly but imminently all the stars are off, resulting then a universe without life, no light, no new stars being born, no new possibilities B) The expansion will continue until the ring and allow gravity to reverse that effect of forward and start a throwback, a BIG CRUCH, a return of all to a single point, to this tiny cluster that ever existed.
are bodies with an extraordinarily large gravitational field. can not escape any electromagnetic radiation or light, so they're black. are surrounded by a "border" sphere that allows light to enter but not exit. There are two types of black holes, bodies of high density and low mass concentrated in a small space, and bodies of low density but very large mass, as happens in the centers of galaxies. If the mass of a star is more than twice that of the Sun, there comes a point in its cycle in which no neutrons can only withstand gravity. The star collapses and becomes a black hole. If a component of a binary star becomes a black hole, taking material from its companion. When the vortex is close to the hole, it moves so fast that emits X-rays So, although you can not see, can be detected by their effects on nearby matter Black holes are not eternal. Although not leak any radiation, it seems they can do some atomic and subatomic particles. someone who observes the formation of a black hole from the outside would see a shrinking star and red until finally disappear. Its gravitational influence, however, continue unchanged. Like the Big Bang, black holes there is a singularity, ie the laws of physics and the predictive power fail. Consequently, no outside observer can see what happens inside. The equations that attempt to explain a singularity of black holes must take into account the space and time. The singularities were consistently in the past the observer (like the Big Bang) or in the future (such as gravitational collapses.) This hypothesis is known as the "cosmic censorship."
Six spacecraft flew by Comet Halley in 1986. There were two spacecraft, Suisei and Sakigake, which took off from Japan, two spacecraft Vega 1 and 2 calls that took off from the Soviet Union, and a spacecraft, ICE, which took off from the U.S., and that he altered course to I could intercept the comet. ICE was the last spacecraft to enter the environment the comet. However, the primary mission to comet Halley was the Giotto mission, a mission sponsored by the European Space Agency. Missions All samples collected from different regions of the environment of the comet, as seen in this picture. The Giotto spacecraft flew close to the nucleus, and won several wonderful photographs of the core. All these missions gathered a wealth of information from the comet.
These stars appear suddenly and only a few are visible to the naked eye showing remarkable and striking lines. The most famous of all Halley's comet, which occurs every 76 years. This comet is named after the astronomer E. Halley, who could verify that their appearances were regular from previous observational records, Halley had observed "his" comet in 1682 and predicted its return for 1758. has been possible to determine the earliest known observation of Comet Halley is the year 467 BC. His latest passage near the sun came in February 1986 and the next will occur in 2062. All comets are part of the Solar System, and some of them very elongated elliptical orbits that their periods of revolution are very long, tens or hundreds of years. observed each year from one to two dozen comets passing near the Sun, but even in these conditions of proximity, only occasionally a comet becomes bright enough to be seen with the naked eye without the aid of a telescope.
are a series of rocky or metallic objects that orbit the Sun, mostly in the main belt between Mars and Jupiter. Some asteroids, however, have orbits beyond Saturn, others are closer to the Sun than Earth. Some have hit our planet. When they enter the atmosphere, light and become meteorites. A asteroids are also called minor planets. The largest is Ceres, with 1,000 km in diameter. Then, Vesta and Pallas, 525. We found 16 that exceed the 240 km, and many small ones. Ida, the photo side, is about 115 km from tip to tip and Gaspra, below, is less than 35. The ships that have sailed through the asteroid belt have shown that it is virtually empty and that the distances between each other are enormous. The asteroid belt formed as a theory, from the destruction of a planet, a small planet. Should 2,500 times together asteroids known to have the mass of Earth. According to another theory, a group of about 50 asteroids were formed with the rest of the Solar System. Afterward, the crashes have been fragmented. Within the belt there are gaps, areas where an asteroid rotates, because of the influence of Jupiter, the closest giant planet.
If Charles Darwin would be turning in his So his theory of evolution today is subjected to trial in Kansas (USA) in a series of Education Committee hearings on the future the teaching of evolution in the state. The hearings, which will last three days have warmed the atmosphere in the state capital, Topeka, where supporters and opponents of a duel open Darwin dispute, which according to the first game is on the divide between science and religion and, as the second, critical thinking. British scientist critics, led by the movement "Intelligent Design" - want textbooks to question Darwinism, especially the idea that man, monkey and other animals have common ancestors. In contrast, followers of Darwin believe that science has nothing to do with a debate after which, they say, lies the growing influence of the religious right in this country. Harris Darwin defends the idea that the mechanisms "adapt and respond to the environment in which they live", but not the principle that "man is an accident." "The idea that different forms of life come from a common ancestor and are the result of a natural, unplanned process is not supported by science," said Harris. Intelligent Design theory was born in Seattle's Discovery Institute, a conservative center opened in 1990 and counts among its founders Bruce Chapman, director of the U.S. census for the administration of President Ronald Reagan (1981 - 1989). Scientists Discovery Institute's claim that neo-Darwinism does not answer such complex mechanisms such as cell structure, which can only be the work of an "intelligent designer." Given the "gaps" that attribute to Darwinism, Intelligent Design proposes that the textbooks do a "critical analysis" of evolution, which "should be presented as a scientific theory open to scrutiny and not as an unquestionable dogma." Although not yet clear how this conflict will be resolved, Darwin has survived similar attacks in the past. Creationists, a group that supports the biblical view that God created the world in six days about 6,000 years ago, have lashed out repeatedly against Darwin. In 1987 the U.S. Supreme Court banned creationism be taught in biology classes, since it is pseudoscientific, and coined the movement as a "religious dogma." Unlike creationists, Intelligent Design says that his theory is agnostic, which gives them a crucial advantage over creationism, the potential to facilitate access to science classes, where they want to derail Darwinism.
osmosis is defined as a passive diffusion characterized by the passage of water, solvent through the semipermeable membrane from a dilute solution to the most concentrated. And we understand by osmotic pressure to that which would be necessary to stop the flow of water through the semipermeable membrane. When considered as semi-permeable to the plasma membrane, cells in multicellular organisms must remain in osmotic equilibrium with tissue fluids that bathe. If the extracellular fluid increases the concentration of solutes, would be hypertonic compared to cells arise as a result of water loss and dehydration (plasmolysis) Also Thus, if the extracellular fluids are diluted are hypotonic compared to the cells. Water tends to move to the protoplasm and cells swell and become swollen and may burst (in the case of plant cell wall cellulose forbid it), by a process of turgor.
