    The Universe in Perspective

    Some of you may have seen this before, or be aware of it but it is still quite awesome to see/know.

    Antares is only the 15th largest star we can see in our skies. Knowing this makes us seem very, very small.

    Kinda makes ya feel realy small. Along the same lines this makes ya feel even smaller, I read it futurehi.net

    The Universe is so huge in fact that we’ll have to play around with scales so one can get a better idea.

    According to the standard inflationary model of cosmology, the visible portion of our universe, the one mapped by our telescopes is an infinitesimally small speck in a much larger universe of at least 10 to the power 35 light-years across!

    Admittedly this number is really, really big, and almost impossible to imagine. So lets shrink everything down, WAY down, just so we can get a better grasp of it. Let's imagine that the entire universe that we have seen in all the worlds telescopes, all the galaxies, all trillion of them, extending out 13 billion light years in every direction is shrunk down to the size of a golf ball.

    If we do a volume calculation, the actual universe contains 10 to the power 60 of those golf balls! Wow, I guess we didn't shrink things down far enough, but this will have to do. So how big a volume would 10 to the power 60 golf balls fill up? Try a sphere 850 light years across! So imagine a mass of golf balls that big, and each one of those golf balls contains all the stars and galaxies that we can see through our telescopes!!

    Now let’s try it with speed. Ready? Imagine traveling so fast that you can go from on end of the galaxy to the other in just one second. At this speed the entire galaxy would be in reach before you can say the word "go", and wham, you're there. At this speed, you could travel to the nearest galaxy Andromeda in 22 seconds flat. And you could cross from end of the visible universe to the other in 72 hours.

    So, lets speed up our warp vehicles again, so that we can travel a quintillion light years every second. At such a speed we could cross the known universe 100 million times in one second.

    How long would it take to cross from one side of the universe to the other?

    the universte is constantly growing. The universe has 3 aspects as most scientists would say but still some skeptics. 4 % of the mass in all the universe is atoms. 21 % mass is Dark Matter. And 75% mass is Dark Energy! Crazy huh?

    the crazy thing is they dont even know what dark matter is and what creates dark energy.

    this is the page I got the info from http://www.futurehi.net/archives/000168.html

    a good read if you like this kind of thing.

    yes i know this, theyre are scientists spending all day trying to find dark matter

    There is a continuation about this in the exact same post he posted, here...

    Some physicists such as Max Tegmark believe the universe is actually infinite in size. If the galactic density of our own neighborhood is typical across this entire domain, and according to the data from the satellite COBE it is, then our bubble-universe should contain at least another 10^100 galaxies. This is such a large figure, that it's difficult to explain it. So to give you an idea of how large a number this is, it's far larger the the number of atoms that compose every object in our own visible universe, which as you remember extends out 13.2 billion light years in every direction. This too is very difficult to conceptualize. So we'll have to scale down even further to a grain of sand. The number of atoms composing a gran of sand is about 1023 atoms, or 100 trillion trillion atoms for each grain of sand on a typical beach. And just think how many grains of sand are on your typical beach, let alone something the size of the Sahara. And that's just on the surface of the earth. All the sand in the world composes much less than 0.00001% of the mass of the earth. The number of atoms composing the Earth is about 10^60. And the Earth in turn is one tiny planet around a small star in an ordinary galaxy, among hundreds of billions of galaxies in our very local neigborhood, which we call the visible universe. So 10^100 is a very very big number of galaxies! Adding it all together and you get more galaxies in our universe than there are atoms composing every object in our visible universe.



    Even if intelligent life is very, very rare, a number as large as 10^100 is still likely to produce an abundance of life throughout the universe. A place where countless lifeforms evolve beyond their womb planets into highly advanced space-faring civilizations.

    For arguments sake, lets imagine that primitive life happens once in the lifetime of a trillion galaxies, and out of those only one in a trillion ever evolves out of its womb planet into a space-faring civilization. In this example then we are still left with an astounding 10^75 advanced societies - more alien cultures than the number of atoms composing planet Earth! Again, for some perspective on such a gargantuan number, there are more advanced civilizations partying it up around the galaxies than there are atoms in every single grain of sand on all the beaches and deserts in the world, and then some. That's more advanced alien civilizations than all the atoms composing our entire solar system!


    Based on these, I'd imagine it is pretty hard to deny it!

    i totally agree bro, there has to be life out there...

    haha jeez, ive pondered this a few too many times late at night when i got 18+ beers in me, stumbling around outside the bar starring up into the sky

    you know what i think is one of the most interesting results of relativity and quantum mechanics?

    its how everything has particle and wave properties. the thought of huge objects behaving like waves (at high speeds) fascinates me.

    the four forces (gravity, e&m, strong and weak) also blow my mind.

    hell, ive always been impressed by gravity.

    did you know that gravity and e&m fields exert surface pressure exactly like a gas does?

    that means that there has to be something there actually in the field

    yea, the ability to suck out the internal energy of the immediate surroundings is pretty impressive...

    I didn't even know there was an "exact thread same to this" nor do I give a fiddlers ****. Im sure there's some ninja threads around somewhere too.

    The pics I got sent to me in a email so I thought i'd share em with people here. It's got a lot of posts so far with you being the most constant poster Tai.

    And yeah, the second piece by Damien was an immense read. There HAS to be other life, in the countless trillions upon trillions of planets out there it would really be ****ed up if we had the only intelligent life. Then again cause the universe is so big prehaps intelligent life is so spread out and apart that none would ever encounter each other?

    Size, is what will always be the problem.

    You could take the tip of a pencil and magnify it. You could then reach the point where a stunning realization hits home...the pencil tip is not solid but is infact composed of atoms. What seems solid to us is only a lose net held together by gravity. Viewed at their actual size those atoms might look to be huge gulfs apart. Atoms of course are composed of nuclei (sp?)and revolving protons and electrons. Further down you have sub atomic particles and then what? Tachyons? And what beyond that? See, size is ALWAYS going to defeat the human mind. We cant say for sure if the Universe has this much dark energy or that much dark matter, there could be pockets of space made up fluid or parts of space where there are no laws of physics. But we'll never know.

    String theory eliminates this constant need to keep going beyond the smallest sub atomic particle to find out what is still smaller than these "strings" because it blurs out any of the turbulance that would be smaller than the strings. Apparently there is no need to go deeper than these strings because it's just turbulance (there really IS no point smaller b/c of the wave vs particle, it's just possibilities). It's like trying to find out what the energy of an earthquake is "made of".

    I for one don't like the idea, I still like to think that there are points in the "foam" of the fabric of space-time that can be broken down, but I guess as long as the elements being used to measure these sub atominc things are still able to be broken down, we'll never know.

    string theory has no real world connection yet. Theorist have worked on string theory for over 20 years and yet they havent been able to come up with any way to even test if it is accurate in anyway. Untill they do its just a exercise in high level mathematics, not physics.

    But there are alot of particles that are point like according to the theory that do work(the standard modell of particle physics). i.e they have no volume or radius. Like the electron or quarks. No experiment so far has ever hinted of the possibility of a internal structure of the electron.

    No it does not, but I like the idea of being able to eliminate the nonsense below Planck level which allows relativity and quantum mechanics to mesh. The theory itself sounds good, but I'd be willing to bet it's just a way to rub out what we can't udnerstand yet...

    I'm still waiting on definitive proof.

    i dont think there is anywhere that the laws of physics dont hold true, but if you go on a small enough (or large enough) scale matter behaves differently.

    things which are incredibly small for example are actually waves. i mean they still have particle like properties, but the wave properties dominate.

    exactly. everyone thinks of electrons as being essentially a tiny sphere, but in actuality it is much better described as a wave
