What is the theory of the Earth Centered Model?

The Ptolemeian model This is the model that also endorsed by Aristole where the earth is at the center of the universe and the Stars, planets, moon, etc. orbit around the earth in fixed orbits almost like the layers of an onion

Did Galileo find it impossible to believe that the earth was the center of the universe?

he found this impossible because when he made his telescope he saw that the earth move around the sun. this theory is call heliocentric, helio meens the sun and centric meens the center.

What is heliocentric and geocentric?

The geocentric theory was the model that the earth is at the center of the universe, and everything (sun, stars,moon,ect.) revolve around it daily. It was disproven about 500 years ago by Copernipus in favor of the heliocentric model which said that the earth went around the sun.

What were Ptolemy's astronomical discoveries?

He created the 'Ptolemaic System' which was a widely accepted geocentric model until the introduction of the more simple heliocentric models. He came up with the value of Pi (3.14166). He wrote several astrology books including the 'Almagest' which is the only surviving comprehensive ancient treatise on astronomy.

How did Tycho Brahe's model the universe differ from that of Ptolemy?

Tycho Brahe used Ptolemy's model but with greater accuracy of measurement. Keplar was able to use the better data to propose the heliocentric model. Newton showed Keplar's model could be derived from Newton's law of Gravity.

When traveling, time is money, and nobody likes to lose it foolishly waiting for a train that never comes, not knowing how the system works. Before traveling, one good recommendation is to become familiar with the transportation services: make better use of the stay.

When using public transport, before the trip, every traveler has to make a little prediction of the time. Unless that it is for something very specific, it is advisable to use single tickets, as they are expensive. However, tickets for one or three days very worthwhile if you will be making several trips.

In many of the major tourist centers, travelers can find public transport pass for tourists only. This allows visitors unlimited travel on specified dates and times, on most public transport available. The availability of a single travel pass, cheap and easy, allowing travelers to use most forms of public transport means that tourist can concentrate on that for which it has traveled: enjoy the stay.

Another important recommendation before traveling is to find out about the options and discounts for age or for tourists. For groups of 3 people or more, it may be useful to rent a car. However, one of the best ways to discover the most beautiful places in the final destination is to go to the sites on foot.

Buying traveler's insurance means an extra expense, but a great saving in case of emergency, so travelers should think about spending a little more in order for them to go with peace of mind.

But the most important thing to consider is that the only way to travel safely is by having the documents that granted entry to the country to visit and travel within it. Travelers always must be sure to consult a travel agent or carrier before traveling to inquire about its policy because the carrier will make the decision when passengers try to board the plane, train, bus or boat. Carriers, and customs officials are responsible for allowing passengers to board the plane, train, bus or boat; and, in most of the cases, governments require carriers to follow very specific rules. These companies will be fined if they let passengers travel without identification and proper documents so, carriers will be always requesting the following documents: passports, travel documents and Tourist VISAS.

Why was Ptolemy important in the roman history?

Please be more specific in regard to Ptolemy -- there were many. One was a mathematician/astronomer and the other was a general of Alexander the Great who founded the last pharonic dynasty in Egypt. There were 15 Ptolemies who followed him and many of them had a relationship with Rome.

When did Cleopatra and Ptolemy XIII go to war?

Cleopatra and Ptolemy XIII went to all out war in 47 BC. Julius Caesar intervened or interfered, (depending upon your perception of the events) and this was the Alexandrian War in which Caesar came very close to being defeated and Ptolemy died.

Creation

I think I have worked out the universe using logic please disprove?

If by "logic" you mean "without God," then the following may be relevant.

Here are some arguments for Creation or against Evolution.

These point to Divine Creation:

  • The staggering complexity of every organ and every cell in the human body.
  • The vastness of our minds and emotions.
  • The fact that the universe has definite design, order, and arrangement which cannot be sufficiently explained outside a theistic worldview. (This is how Abraham, without benefit of teachers, came to reject the chaotic world-view of idolatry and the possibility of atheism). For example, theoretical physicist and popular science writer Paul Davies (whose early writings were not especially sympathetic to theism) states concerning the fundamental structure of the universe, "the impression of design is overwhelming" (Davies, 1988, p. 203).
  • The laws of the universe seem to have been set in such a way that stars, planets and life can exist. Many constants of nature appear to be finely tuned for this, and the odds against this happening by chance are astronomical.
See: More detailed evidence of Creation

Also:

1) The glaring lack of transitional fossils has been noted by the evolutionists themselves, such as this statement from the famous paleontologist and evolutionist George G. Simpson; quote: "The regular lack of transitional fossils is not confined to primates alone, but is an almost universal phenomenon."
"The lack of transitional series cannot be explained as being due to the scarcity of material. The deficiencies are real; they will never be filled" (Nilsson, N. Heribert).
"To the unprejudiced, the fossil record of plants is in favor of special creation" (Corner, E.J.H., Contemporary Botanical Thought).
2) Instances of falsifying of evidence by evolutionists, such as Haeckel's drawings, Archaeoraptor, the Cardiff "specimen," and Piltdown Man.
"Haeckel exaggerated the similarities [between embryos of different species] by idealizations and omissions, in a procedure that can only be called fraudulent. His drawings never fooled embryologists, who recognized his fudgings right from the start. The drawings, despite their noted inaccuracies, entered into the standard student textbooks of biology. Once ensconced in textbooks, misinformation becomes cocooned and effectively permanent, because textbooks copy from previous texts. We do, I think, have the right to be both astonished and ashamed by the century of mindless recycling that has led to the persistence of these drawings in a large number, if not a majority, of modern textbooks (Stephen Gould).
Dr. Jonathan Wells published a book in 2002 entitled Icons of Evolution. Dr. Wells states that the book shows that "the best-known 'evidences' for Darwin's theory have been exaggerated, distorted or even faked."


3) Creationists see the "survival of the fittest" and the dating of rock layers by fossils as being perfect tautologies.


4) The fact that some qualified, educated, normal scientists do not believe in evolution. Or at least question it, even if they still preach evolution: "Nine-tenths of the talk of evolutionists is sheer nonsense, not founded on observation and wholly unsupported by facts. This museum is full of proofs of the utter falsity of their views. In all this great museum, there is not a particle of evidence of the transmutation of species" (Dr. Etheridge, Paleontologist of the British Museum).
"To postulate that the development and survival of the fittest is entirely a consequence of chance mutations seems to me a hypothesis based on no evidence and irreconcilable with the facts. It amazes me that this is swallowed so uncritically and readily, and for such a long time, by so many scientists without murmur of protest" (Sir Ernest Chain, Nobel Prize winner).


5) The fact that there is a shared, worldwide tradition among every ancient society that the world was created.


6) Evolving of new organs or species has not been witnessed during known history.


7) Mutations are harmful, not beneficial. One of the tasks of DNA and of long-term breeding is to avoid or repair any changes brought about by mutations. This means that our genetic apparatus is programmed to resist change.


8) Mutations, even if beneficial, do not create new organs.


9) The fact that a great number of fossils have been found in the "wrong" rock-layers according to what evolutionary paleontology would require.


10) The fact that you need DNA to make DNA. No genetic code can be demonstrated to have arisen by chance, together with the ability to read that code and carry out its instructions. Information does not arise spontaneously; and there is an incredible amount of information in even the tiniest cell.
"A living cell is so awesomely complex that its interdependent components stagger the imagination and defy evolutionary explanations" (Michael Denton, author).
"The astounding structural complexity of a cell" (U.S. National Library of Medicine).
Concerning a single structure within a cell: "Without the motor protein, the microtubules don't slide and the cilium simply stands rigid. Without nexin, the tubules will slide against each other until they completely move past each other and the cilium disintegrates. Without the tubulin, there are no microtubules and no motion. The cilium is irreducibly complex. Like a mousetrap, it has all the properties of design and none of the properties of natural selection" (Michael Behe, prof. of biophysics).


11) The problem of the impossibility of abiogenesis in general. "The concept of abiogenesis is not science. It's fantasy" (J.L. Wile, Ph.D.).


12) The fact that evolution was once used as support for the belief that Blacks (or others) are less than highly-evolved humans. "Darwin was also convinced that the Europeans were evolutionarily more advanced than the black races" (Steven Rose, author). He also "reasoned that males are more evolutionarily advanced than females" (B. Kevics, author).


13. The first and second laws of thermodynamics point clearly to a Creator, since things undergo entropy rather than get more orderly over time.


14. "Radiometric techniques may not be the absolute dating methods that they are claimed to be. Age-estimates on a given geological stratum by different radiometric methods are often very different. There is no absolutely reliable long-term radiological clock. The uncertainties inherent in radiometric dating are disturbing to geologists and evolutionists." William D. Stansfield, Ph.D., Instructor of Biology, California Polytechnic State University.


15. "Even total rock systems may be open during metamorphism and may have their isotopic systems changed, making it impossible to determine their geologic age." Prof. Gunter Faure (Department of Geology, The Ohio State University, Columbus.)


16 a). At current rates of erosion the amount of sea-floor sediments actually found do not support a "billions of years" age for the Earth.
b) The amount of Sodium Chloride in the sea, also, is a small fraction of what the "old Earth" theory would postulate.
c) The Earth's magnetic field is decaying too fast to extrapolate a long age for the Earth.
d) The rate of accumulation of Moon-dust has been measured; and the amount of dust on the Moon was found to be vastly less than what scientists had predicted before the Moon-landings.

See: Problems in Evolutionary astronomy

e) Helium is generated by radioactive elements as they decay. The escape of this helium into the atmosphere can be measured. According to the Evolutionary age of the Earth there should be much more helium in the atmosphere, instead of the 0.05% that is actually there.Also see:
