This is a brief review of the Revolution in astronomy by Bahram Katirai in 2008.

This book is a trying to rewrite the laws of physics, astronomy and mathematics to make universe make sense to them or their worldview. They are not the only ones, the first ones or the last ones. They try to explain away how stars and galaxies are actually just planets and they are a lot closer to us because astronomers are wrong. They simply do not try to explain the techniques astronomers use, or interpret them wrong either on propose or they simply do not understand them,

In the first chapter the author starts talking about the light collecting area of a telescope. One thing larger telescopes allow astronomers to see is objects that are smaller than what the human eye can see. This is called resolution, one of the stats that your cell phone producers use to sell the phones is how many megapixels the camera has. The more and more megapixels the smaller and smaller detail you see in the picture. The smaller the resolution a telescope can see you get more and more detail in image you get from the telescope. This comes in useful when you are measuring the distance to the stars using a method called parallex. This method is done by measuring the angle that is made when you observe an object from two different spots. The relation between the length of the line to the star and length of the line from the Earth to Sun is known which is 206265 so if the angle between is measure to be 1 sec the distance to the object is 206265 times that of Earth Sun relation, This distance between Earth and Sun is called an astronomical unit which is 1.49 *1011m. For a long time the distance was just expressed in terms of how many paallex seconds the object or parsecs because the distance between the arth and sun was unknown.

Another way astronomers measure the distance to stars is by measuring the Flux or the energy per meter that comes from the star. It was long way around to come up with this method. Firstly Hippachus came up with a scale on rating how bright a star was. It started at 1 for the brightest and went to 6 for the dimmest these are referred to as the visual magnitude of the star. In the 19th century when they thought the eye saw brightness on a logarithmic scale the difference between magnitudes became 2.512. Some objects actually had negative values such as the Sun which is at -26. Also the concept of an absolute magnitude came about, this what would be the magnitude if it was held a distance of 10 parsecs or 32.6 light years. In the twentieth century devices called photometers came about that could measure the flux directly. So we can compare the flux from where the star is compare it at 10 pc and we can figure out the distance to the star.

F10/F=(d/10)2

d is the distance in par secs, F10 is the flux at 10 parsecs,f is the measured flux of the star

The author tries to state that stars are planets that are just misunderstood. The look at a picture of Uranus and an image of a similar colored star and makes the assumption thar the star is just a planet. The main problem here is that astronomers now that stars are not made out of the same stuff as planets. The way they know this is that they m split the light from the star thru a prism. When you do this we will see a band of light that will start blue one side to re to the other, there is more light there but our eyes cannot perceive this light. If look more closely at this light we see black lines in band, Every atom or molecule with will produce there own characteristic pattern of lines under certain conditions. The pattern from the stars are a combination of the patterns from atoms and if cool enough molecules. So stars composition is easily demonstrated to be different than a stars.

They try to discuss away the change in Cepheid variables which change brightness over time. Cepheid are stars that are unstable because of changes going on in the core, they change brightness over a well known time. So if an astronomer so a star changes with a certain period they know the brightness of the star at its max and at its min so the can use this to find out how far away the star is. In this book the claim a Cepheid is just a planet spinning One side of the planet is redder than the other so it when it revolves around its axis it changes color. One thing the author seems to not understand is spectroscopy. When an object revolves the light will shift to blue on one edge that is moving towards the observer and redder on the edge that moves away from the observer. Cepheids change brightness as rotating So Cepheids are not just spinning objects that are just two different colors on either side.

In anther chapter the author tries to explain away galaxies as stars that giving off gas of hydrogen and molecules and forming planets. He looks at a few pretty pictures and sees a bright spot in the center and spirals coming off then some clumpy spots in the arms calling these planets. First off there are several types of galaxies they are, irregular galaxies that are clumpy masses of stars and gas, spirals which look like well spirals and ellipticals which are look like foot collections of stars and little gas. Astronomers used large telescopes and found many, many stars in these galaxies throughout the object. Also using cepheids they know these objects are in the order of millions and billions of light years away. Also it was found that if something emitting light moves away from the light, the spectrum will be shifted to the red end and if moves away from you light is shifted to the blue. Radar guns to determine if a car is speeding works under this principle. The radar gun sends out a pulse of light and is bounced back and the detector does some calculations and tells the cop whether or not to right you a ticket. In the middle of spiral galaxies like our own they have been measurements of the stars orbiting the core region are travelling at such a speed that the probably are super massive dead star called blackholes.

In chapter 12 the discuss the birth of planetary systems. Planetary systems are formed when the star is formed, the planets are formed out of the stuff that is blown off from star as it forms. In this chapter they show pictures of planetary nebulae. These objects are actually when a star like the sun is at the end of its life it will puff off the out layers of the star. These forms rings and sometimes will form other shapes as well. Then they jump to images of galaxies which are completely different because they have many stars in them.

In Chapter 13 they discuss how the sun is in the center of the milky way. If you go out in summer you will notice that there are more stars visible than in the winter months. This is because during the summer we are in the part of the orbit that looks towards the galaxy and in winter we a looking outwards into the lower density parts of the galaxy. (If you are in southern hemisphere the seasons would be reversed.)

This book is trying to refute modern astronomy by just looking at some pretty pictures contrary to what scientists do by measuring, modelling, and coming up with theories. This general technique is often used by individuals who have issues with what science has come up thru hard work and reasoning. There might be a few reasons for it either religious,or conflicts with other world views
