    A good read for the weekend....how big is the Universe thought to be?

    Sometimes, I just like to look up odd things on the net. It is so much easier now days to find stuff than it was even 10 years ago...and so much info more update and available.

    Been reading about where the center of the universe might be, if it has a center at all. Fascinating read. Seems most say that there is no center, because even if the universe started out as just a point, there was no big bang like explosion to create the universe. Best as I understand it, the Universe was incredibly small, and then somehow just expanded like a loaf of bread rising.
    Then others try to say the universe is like the surface of a balloon expanding, only that 2d picture is happening in 3d.
    You'll actually need to search "Where is the center of the Universe", to see the different articles to get a good overview.

    Oh, and the center isn't in Oklahoma....nor Idaho.

    One guy said the whole Universe was the size of a peach, (probably a freestone peach) and then expanded to the size it is now and still growing. Also, they say the universe is 13.8 billion years old. Then, it is surmised that the universe is at least 98 billion light years across.
    I'm going to have sit down this evening and see how big and at what rate a peach had to grow in that time to be that big.


    Then some say the microwave background radiation proves the Big bang theory, because it is uniform thru out the universe. Then another article says the "southern hemisphere" of the universe is a bit warmer than the "northern hemisphere". Kinda throws a bit of a kink in their thinking, or so the article said.

    Of course, in all this, they admit they don't know what was Before the big bang, what might have caused the big bang (expansion), or what exist into wherever the universe is expanding into. Some say there is nothing "beyound# the universe, or else we would see starlight, but because we don't there is nothing out there "beyond". But then, they didn't see any stars in one spot of sky untill they trained the Hubble telescope on it for several days. Then they found about 10,000 galaxies.

    Anyway, something to study on while I relax in my retirement easy chair.

    Been thinking on the expansion rate of the universe since the "big bang".
    We are told that the universe is 13.8 billon years old, and that it is at least 50 billion light years across. That's a fair number of zeros to work with, so let's cut it down some. Let's divide the age into the distance to see how much it expanded each year.

    50,000,000,000 light years ÷ 13,800,000,000 years = 3.623188486 light years distance in 1years time.


    As light only travels 1 light years distance in 1 year's time, then we can conclude that the universe is expanding at 3.62.... times the speed of light. That being so, the boundaries of the universe is outrunning the expansion of the mass inside the universe.
    Now the boundary of the universe is still a part of the universe, so how can it expand faster than the speed of light? If it takes infinite energy to accelerate to the speed of light, then where does the universe get infinite energy to expand at 3 times the speed of light...much less at even the speed of light?

    Some people tell us the universe could be 100 billion light years across, or even up to 250 billion light years across. That would mean the universe has to be expanding at 6.4 to 16 times the speed of light. Mighty fast indeed for a universe that limits itself to the speed of light.
    That seems pretty implausible to me. I find it easier to believe the universe has always existed, and in infinite size.

    Ageless and limitless.





    As for looking for gravity waves from the big "big bang", think of tossing as stone into the middle of a large lake. The ripples will continue to expand out and out, until they meet some barrier to bounce back off of.
    The same with gravity waves. If the universe is expanding at faster than the speed of light, then gravity waves will never be able to catch the boundary of the universe to bounce back off of. And much like the ripples on a lake, gravity waves will eventually weaken and cease to exist.
    This is not to say we can't sense gravity waves, say from black holes and such, because we are in a position to be impacted by some of them. But if the boundary of the universe is forever expanding faster than the speed of light, then it will never be in a position to be impacted by any gravity wave left over from a " big bang".


    Another thing I read, is that no matter which way we look, we see every galaxy speeding/expanding away from us. And the farther away, the faster they are going. So, ii says if we look at something the farthest away we can see, we will see it receding at almost the speed of light. And if they look at us, they will see we are receding from them at almost the speed of light. Thus, because from each of our "relative view point", we seem to see an object at near the speed of light, the universe must be expanding at the speed of light.
    No thought to say that the other object might be traveling so 48℅ the speed of light, and we might be traveling at 50℅ the speed of light in the opposite direction, and thus it only appears that one or the other is receding, not both at lessor speeds. Much like two cars traveling at 60 mph in opposite directions. At the end of an hour, each car has traveled 60 miles, yet they are 120 miles apart. Shall we then say that one car drove 120 mph because it "might appear so"?
    Of course not. And we can no more say galaxies are traveling at near the speed of light, when we actually don't know our own speed in the universe....much less the speed of the other.
    And to say the red shift of light proves they are is to simple, because we don't take into account how our own velocity impacts Doppler shift of the incoming light.

    A note to the internet grammar nazis,...an apostrophe ' is just a comma , raised to the ⁿ power.

    ,’ⁿ

    And quote marks " are just apostrophes squared ²...'²

    But then, maybe exclamation marks ! are just question marks ? on Viagra.

    Maybe a semicolon ; is just a male colon : the colon being female

    Funny thing about that speed of light "barrier". I remember as a kid growing up hearing sonic booms before they were outlawed. At one time the speed of sound was known as the "sound barrier". There was also a time at the beginning of the horseless carriage era, when it was thought that the human body could not stand speeds in excess of 60 miles per hour.

    There was a time you would be locked up if you said that one day man would soar through the air, 7 miles up at 600 miles per hour, with hundreds of other people, in shirt sleeve attire, in an aluminum tube with wings.

    We just haven't gotten to the point that we have learned to work around and beyond the bounds of light speed.

    I think the speed of light is true for "light" only. I see no reason why faster than light speeds are not possible.

    I think light is limited to a set speed in a vacuum due to the unique nature in which light originates...which I have mentioned before.

    In order to travel AT the speed of light, matter would have to be turned into electromagnetic energy, as electromagnetic energy is the only thing that can reach that speed.

    Now, if we could figure out a way to convert matter into energy, send it somewhere, then turn it back into matter (unchanged from the original matter), then light speed would be possible.

    Going faster than that is impossible based on the science (physics) we have today.

    You know, you turn on an electric light, and the filament heats up and emits light...and it doesn't take all that much energy.

    Besides, just what says nothing can go faster than light? Don't say because science says so; quote the scientific fact. I haven't found it yet, other than it's because of relativity...and I see flaws in that theory. And so do smarter people than I.

    Well, as I've said, I don't think light speed is a barrier to anything,...and I don't think relativity has anything to do with it.
    But, that is just my thoughts on it, which I put out for consideration.

    Speaking of light, here's an interesting fact about the light from galaxies that would have never crossed my mind. It comes from a poster on another board.

    The Andromeda galaxy is approximately 2.5 million light years away. It is also about 200,000 light years across. Just looking at Andromeda and you would probably think the light from it is 2.5 million years old. But the poster astutely pointed out that because of its size, the light we see from the far edge of the galaxy is 200,000 years older than the light we see from the near edge of the galaxy.

    As far as I know, no matter how fast you are traveling, you cannot add to the speed of light.

    Think of it this way, if a car is coming at you at 100 miles per hour, and you could add 100 mph to the speed of light, then the car would appear to reach you faster than it really does.

    I know you can't download any videos on your phone, but this was covered by Carl Sagan in the Cosmos series, and the It's About Time program.

    Actually, light is the most special thing in the universe, and this is just one of the things that makes it so special.

But the poster astutely pointed out that because of its size, the light we see from the far edge of the galaxy is 200,000 years older than the light we see from the near edge of the galaxy.

    In a way, that's correct. When the light first left Andromeda, the light closer to us would have reached here first, but since the light that reaches us now has had time for the light, from the back of the galaxy has had time to reach us, it looks complete. However, if we could instantly go there, we might see that some of the stars we are able to see from earth have burned out now, and some new stars have already formed.

    Another thing to think about is could quasars be like what you described above, but the light from the backside of the galaxy hasn't had time to reach us yet? In other words, is the quasar just the closest edge of the galaxy's light just reaching us? As time goes on, will they start to appear more galaxy-like to us?

    I think quasars are believed to be the energy and mass that is just starting to form into galaxies....but, who knows for sure?

    Actually, light is the most special thing in the universe, and this is just one of the things that makes it so special.
    So, would I assume if light somehow traveled slower leaving the car, then it would appear to reach me slower than it really does? To me, both statements are equally wrong. The speed of light has nothing to do with it; we would see the car reach us when it reaches us.
    There is nothing special about light. People have accepted that the Theory of Relativity has given it magical powers, but all things being relative...it hasn't.

    Your example hasn't answered my question. Adding 100mph to the speed of light wouldn't change anything but the speed of light.

    What is it about light that makes it always at speed C, without regard to the velocity of the mass it originates from?
    I believe there is a simple, physical explanation, and it doesn't depend on "appearances" for an answer. I keep asking simply because I've never seen a logical answer, only answers that light is somehow magical and can do all kinds of miraculous things to keep us in the dark.

    Now, I know it might sound like I'm trying to put you down, or I sound arrogant like I'm smarter than everyone, but neither of those are true. It's just if we are to understand the speed of light, we need to understand light itself.
