    great set of videos i watched on does god exist.. in my opinion anyway

    And there we have a shining example of what is wrong with American education. In the midst of a thread on physics and cosmology, Stacy mindlessly drops a post about biology and the origin of life, a completely different field of science.
    It reminds me of when I had to explain to my news director what the difference between archaeology and paleontology is.

    I run into a lot confusion about archaeology and anthropology myself. Especially in the US where archaeology is considered a sub-field of anthropology.

    Re: Flat universe and the big bang theory

    not really the scientist i posted have debates on all the subjects .. i find all of them fascinating and listen to a different one every day .. Lawrence Krauss's has a book or two .. A Universe from Nothing. sorry about the quick post but i just found that there was even a thread about anything remotely close to cosmology and or physics especially when it comes to the universe . hell all my buddies hear the word cosmology and think im talking about cutting hair... lol

    the other videos i posted even though its a proof of god playlist he does talk about physics and the universe as well.. im just now hearing different theories on the universe and what it might be shaped like , and questions about if it is expanding or in a flat plane or are we riding on the edge.. just different theories none OF which am in expert on or even remotely will pretend to be ...lol.. sorry for my ignorance but i love to learn new things and these subjects do interest me .

    Next time, Stacy, create a new thread for what you wish to talk about rathering than necroposting in one about a different set of subjects (and made by a troll at that).

    I read articles such as this one and wonder just how arrogant mankind has to be to even think for one moment it "knows" what happens / has happened out "there" much less when it happened.

    Also, I apologize for an error in my previous posting. For some reason I had thought that Edmund129 (the troll) had started this thread, rather than consolidation. The mistake is mine.

    You have nothing to apologize for. Your government should be apologizing to you for the state of education in the U.S.

    i found that everyone of my employees that ive had the pleasure of coaching and working with over the years that have college degrees have traded most of their common sense in for book knowledge . I guess the job market is just that bad where the degree they went to school for that those jobs are scarce.

    I would love to go back to school if we had classes where we learn things of this nature . but I would hate to go to school and then become so arrogant and self absorbed where I felt that any of this knowledge made me better than someone that does not know about these things . .. I guess when some people go to school and memorize more material they somehow become less humble .. I would be thankful and wish to share my knowledge not ridicule or belittle those who are not at the same level..

    First, find a community college near you and look at the list of classes.
    Second, ask the staff there to help you look into getting the financial aid from the federal government to cover the cost of tuition and books.
    Third, education doesn't make you arrogant and self-absorbed. It's your decision what type of person you want to be.

    And all of that has WHAT to do with the state of education in the USA ??

    Burying your head in the sand or turning the discussion into an ad hominem attack on the person/s pointing out the shortcomings in the system while the rest of the world leaves your country in its' dust, education wise, is part of the problem, not part of a solution.

    Given this is another of my academic interests I'll attempt to explain. There is a whole philosophy about knowledge - epistemology and there is how we know about things - ontology. We can go a great deal into this but let me assume you accept what knowledge is and what facts are. So we ontological acquire epistemological awareness i.e. we measure things and those measurements give us a map of what is out there.

    When it comes to knowing about the universe as a whole we have little hands on experience. the furthest we got from Earth was when 15 people went about 250,000 miles away back in the early 1970s. since then we have not gone more than about 200 miles off the surface although the numbers that have done that is in the hundreds.
    WE have however developed ways of looking at the universe. The electromagnetic spectrum ranges from radio through microwave; infra red; visible light; untraviolet; x ray and gamma rays.
    Microwaves are difficult to measure on earth but we have big radio telescopes which stretch across continents. These measure far away sources like neutron stars and black holes. Currently we are building four Big Space telescopes in Infra Red (IRAS was the first) Visible ( the Hibble) UV and x ray (indias astrosat covers much of this)

    Anyway we have some assumptions and some things we can measure and from that most of what we "know" about the universe is conjectured. Well to be really fair we have some particle accelerators which show what matter is like at really high energies which equates to the Early Universe but Im getting ahead of myself here but suffice it to say we can measure how matter behaves at energies higher than the center of Stars.


    The assumptions - only TWO. It is assumed that the laws of physics always act the same way everywhere in the universe and it is assumed matter is fairly evenly spread the same in all directions ~ homogeneity and isotropism. Now I know you might be on the Earth and think all that space up there is empty but think of throwing salt on a table top and measuring the amount of salt grains under a postage stamp. You would get roughly the same number of grains no matter where you put the stamp if the salt is evenly spread. Similarly galaxies are evenly spread. We can measure this by the way and the number of galaxies in that Hubble Deep Field is one example of doing just that. So maybe a lot of technology but the iead of evenly spread and the law of gravity or electromagnetism working the same everywhere isnt a huge thing to grasp.

    Okay there are then some things we can measure. the cosmic Microwave background is one. If we look at the sky in the visible spectrum we see stars. If we look at the Moon is is bright but it had a low glow in infra red because it is giving off heat ( IR is like one of them COPS night vision cameras) If we looked in x ray or higher the sky would be dark but ever few days we would see a bright false at random. these Gamma ray bursters are probably distant super novas. So as we move down the spectrum from ther we see blue stars then red stars then infra red dead stars but suddenly in the microwave range the entire sky becomes bright. Something is coming from every direction we look at the limit of our ability to see. Now this is a remnant of the Big Bang.

    Again Im getting ahead of myself but if the universe was expanding it is now cooler than it was this microwave 3 Kelvin in Temperature signature represents about 3000K about 15 thousand million years ago. Before that electrons and protons couldnt stay together because that that temperature ( similar to the surface of our sun) electrons are "boiled off" atoms. all these particles jumped around like a lotto machine. Imagine trying to throw a marble through a lotto machine the size of a country. It would keep hitting balls. Photons likewise hit particles until the particles cooled enough to be bound into atoms. When that happened the Universe allowed light to cross it in all direction and that is the background we see today in every direction we look. The Cosmic Microwave Background CMB It is at the right temperature to convince us particles of matter were evenly spread. evcept when we look in higher detalil ther are slight differences which means ther were tiny clumps of matter where it was a bit denser and that is what formed into galaxies.

    Now we can look at Stars today and see they change Hydrogen into Helium so in the past there was a little more Hydrogen and a little less Helium but even today it is still about 3 to 1 in ratio. Hydrogen makes up about 76% of the universe and Helium 25% ( in referring to normal matter here ther is other stuff we cant see but that will take more time to explain) all of the rest Oxygen Gold etc. are less than 1$ of the amount of matter.
    Now we can explain how the 3 to 1 Ratio came about using equations and we can verify them using particle accelerators.

    Finally we have the cosmological red shift. You may be aware how a siren drops down in pitch as a car passes. the car as it approaches adds its velocity to the wave and as it recedes subtracts it velocity changing the pitch. THe "pitch " of light is frequency or its analogue wavelength. High energy has shorter wavelength and is bluer and lower energy redder. Light also seems bluer as something moves towards us and redder as it moves away. In fact we can see two sides of a rotating galaxy one exhibiting red and the other side blue shift. anyway most things in the universe are red shifted = moving away from us and ther further away they are the faster they are moving away. This suggests ( and this is reasonable but is a very clever conclusion that Hubble made) that the universe itself is expanding. Cosmological REd Shift CRS

    Now here is the point to where I jumped. If expansion means cooling then it was hotter in the past.

    So if we assume homogeneity and isotropism then
    CMB + CRS plus a 3/1 H/HE ratio suggest an origin in a single point in time and space i.e. a Big Bang.

    Not alone that but measuring the expansion today ( the so called Hubble Constant which isnt actually constant) we can estimate WHEN that happened.

    Thats how we "know" about it.

    As far a science is concerned it is still a hypothesis.
    Actually it is a physicist who coined the phrase. I believe Fred Hoyle A British Radio Astronomer who didnt accept it said he thought the Universe was Steady state and not a "Big Bang" and the phrase stuck.

    But when you say it is a theory. Yes like atoms are theories and evolution is a theory and germs are a theory. It is extremly plausable even if based on a few large scale observations. WE could of course be in an infinite universe but if that is the case how come the whole sky isnt bright because eventually in an infinite universe you would reach a star no matter what direction you chose and the light would shine from there to here. SO it stands to reason the universe is finite. Now ever since Hubble's first experiments we have been measuring red shift and the further we look the faster it is. How can you explain that if it is not expanding?

    I might add that abiogenesis (the spontaneous creation of life) is not evolution ( the changing of species over time)

    You know, some people believe that the Earth is flat...
