Is the universe round?

[rodrunner79]

Hi everyone...<br /><br />They say that cyclones rotate clockwise in the southern hemisphere, and counterclockwise in the northern. If this is true then could the globe (earth) being round has anything to do with this? <br /><br />Now, I'm going to think big and ask, for most galaxies that has a supermassive object on the center (a blackhole perhaps) and has matter/particles spinning towards it or around it, which way does the matter/particles spin? Now if it spins both counter and clockwise, then doesn't that mean that the universe is round as well? <br />

As far as I know the galactic planes are radomised = every possible orientation, but I don't see how that is evidence that the galaxy is round or spherical. My guess is a spherical Universe, but the main stream opinion is the Universe is a non- spherical, many dimentional construct. Neil

The fact that the earth is sphere-shaped imparts a clockwise spin on cyclones in the southern hemisphere and counterclockwise spin on hurricanes in the northern hemisphere. This spin is caused by the friction of the wind against the surface of the earth as the weather system tries to find a state of equilibrium. The diameter of the earth is greater at the equator. The rotations of the spin are the direct result of the wind encountering greater friction in the direction of the equator as the earth rotates beneath. The wind actually has to travel farther in the direction of the equator than toward the poles. <br /><br /><font color="orange">Now, I'm going to think big and ask, for most galaxies that has a supermassive object on the center (a blackhole perhaps) and has matter/particles spinning towards it or around it, which way does the matter/particles spin?

Spiral galaxies spin due to an enormous gravity well at their centers. This gravity well, caused by a very massive object which creates a super massive black hole, imparts a gravitational effect upon stars in the core of the spiral galaxy. This rotating galactic core imparts gravitational forces on other outlying stars in the galaxy. <br /><br />The direction of rotational spin of a galaxy is determined in the infancy of the developing spiral galaxy. Those stars that didn’t orbit efficiently in one direction or another around the super massive object at the core of the developing galaxy</font></font></font></font> <div class="Discussion_UserSignature"> </div>

<i>"What is the shape of the Universe"</i><br /><br />This is such a quaint philosophical question and everyone has their own opinions and descriptive ideations.<br /><br />There are some interesting mathematical models which try to demonstrate the shape of the universe. E=mc[sup]2[/sup] is a masterful effort; but it isn't easy to visualize the implications of such a thing and it merely highlights an unpalatable reality, which is - <i>our universe is a really wierd place!</i> <br /><br />Some interesting three-dimensional models of our four-dimensional universe would include: The tesseract (also called the "Hypercube" model), the torus (mmmm, donuts!), the brane (a hair-brained idea), an expanding balloon analogy (full of hot air) and many, many other creative conceptions.<br /><br />In a nutshell, (my apologies to Stephen H.), the shape of the universe is a <b>"Singularity"</b>, a "1"; a single point! I <i>know</i> this is a bit mind boggling to conceptualize, but everything we observe about the universe shows that we actually live within an infinitesimally small point.<br /><br />A long time ago (about 13.5 to 16 billion years ago, by some estimates) our Singularity universe underwent a Big Bang and "Inflation" event; this was the very start of time, energy and matter - the universe! (Whatever came before the Big Bang is another philosophical question and I won't go there...)<br /><br />The Big Bang event (and thus our entire universe) has occurred wholly inside of this Singularity! There was nowhere else for it to go. There is just no reference point to suppose anything exists outside of our Singularity universe!<br /><br />There are several clues which tell us our universe is indeed still just a Singularity and expanding into itself; note that <i>every point in the universe shares these peculiar perspectives:</i><br /><br /> 1. Every point in the universe sees itself as the oldest point in the universe. <br /> 2. Every point in the universe sees itself as

All the planets are round. All stars are round. The galaxies spin round. A bubble is round. Electrons go around in a circle. <br /><br />I think the universe is round, but maybe not as a sphere, but like a round plate with a flat plane like our solar sytem is. Who really knows???<br />

 

[dragon04]

I think the fact that all galaxies are red shifted in all directions relative to our perspective here on Earth can indicate that the Universe isn't "plate shaped".<br /><br />And from computer models I've seen of the universe, matter is not evenly distributed. So my guess would be that the Universe has a very odd shape. <div class="Discussion_UserSignature"> <em>"2012.. Year of the Dragon!! Get on the Dragon Wagon!".</em> </div>

If the universe had a yellow tint to it, were cylindrical in shape with a bump on top, and something resembling a propeller on one end, would it be accurate to say that we all live in a yellow submarine? <div class="Discussion_UserSignature"> </div>

averygoodspirit - Cyclones have spin, not because of wind friction, but because of the coriolis effect on wind cycles:<br /><br />(Ecclesiastes 1:6) . . . The wind is going to the south, and it is circling around to the north. Round and round it is continually circling, and right back to its circlings the wind is returning. . .<br /><br />Note the verse concisely is describing all of planet earth's wind cycles - hence it only mentions north and south but omits east and west.<br /><br />The reason for this is that all wind cycles share a north and south component, both the horizontal cyclones and anticyclones, and the huge vertical wind cycles caused by uneven solar heating.<br /><br />For one example, air rises at the equator (region of the Doldrums) and is replaced from the North north of the equator, and south south of the equator. The earth's rotation then adds its effect, see the coriolis effect.<br /><br />Did the universe have some spin that imparted spin to galaxies, a sort of universal coriolis effect? I doubt it, btw.

Newtonian:<br /><br /><font color="orange"> averygoodspirit - Cyclones have spin, not because of wind friction, but because of the coriolis effect on wind cycles:<br /><br /><font color="white"> That is correct. Good job Newtonian. Friction slows hurricanes down. You corrected the hard one regarding the carioles effect, but you could have also corrected me on this statement.<br /><br /><font color="yellow">“Galaxies which have no massive object in their cores form a different class of galaxy known as globular clusters. Globular clusters are typically smaller than spiral galaxies in the amount of space they occupy and the number of stars contained within them. Therefore, they are less massive than spiral galaxies.”<br /><br /><font color="white"> An average amateur astronomer coulda woulda shoulda been all over that statement. <br /></font></font></font></font> <div class="Discussion_UserSignature"> </div>

How can we know what the shape of the universe is without knowing what is beyond it?

"Did the universe have some spin that imparted spin to galaxies, a sort of universal coriolis effect? I doubt it, btw."<br /><br />What would cause our unvierse to constantly accelerate? The easiest way to get a constant acceleration is to use a rotational motion. If the universe is a four dimensional sphere rotates around a fifth dimensional axis, and this axis is orthogonal to 4D hyperplane which includes our universe. <br /><br />If rotation creates centripetal acceleration, which is orthogonal to the universe's space in every point. This centripetal acceleration cause space to curve in vicinity of massive bodies. In the curved areas the acceleration is not orthogonal to the space, which appears to objects as gravity.

<b>Finaldeathh -</b><br /><br /><i>"How can we know what the shape of the universe is without knowing what is beyond it?"</i><br /><br />Well; if we accept the current theories dictated by mainstream scientific thought (Big Bang, Accelerating Expansion of the Universe, E=mc², etc.); then we can make some educated extrapolations concerning the shape of our universe. <br /><br />If the universe is expanding; then we can deduce that in the past it was smaller than it is now. <i>Much smaller!</i> In fact, mainstream cosmologists now accept the impossible notion that our entire universe began as an infinitesimal point; a <i>singularity!</i> <br /><br />(Note that the idea of something "Beyond" the singularity is a null concept. The singularity "Is" the universe and it is impossible to refer to an existence outside the universe - this concept is just not valid and has no real meaning.) <br /><br />When Big Bang event occurred in the singularity; time, space, matter and energy were created. Since there is no reference for "Outside" the singularity; the universe had to inflate entirely within the confines of the singularity - our universe exists entirely within an infinitesimal point.<br /><br />The universe still acts very much like the singularity it is. Every point in the universe shares the common perspective that it is the oldest and most central point in the universe!<br /><br />Every point in the universe shares the illusion that they are located in the center of an expanding balloon! Our universe is just a tiny singularity which is expanding into itself.<br /><br />Makes you feel kind of small, doesn't it...<img src="/images/icons/smile.gif" />

A wise man once said, "Wherever you go that's where you are". <br /><br />Would it be safe to say that the universe is an infinite sphere where every point is the radius and the circumference is nothing?

 

[scull]

The universe is shaped like a saddle; you know who likes to ride it.<br /><br /><br /><br /><img src="/images/icons/smile.gif" />

Yep, Space cowboys. <img src="/images/icons/wink.gif" /><br />

<img src="/images/icons/smile.gif" /><br /><br />LOL <img src="/images/icons/smile.gif" /><br /><br /><br />I come here to learn. Please don't teach me crap. -- s<br />

 

[eric2006]

O.K. I won't. <br /><br />But you do know that every possible scenario branches into it's own universe. There is a universe where scull is gobbling up all of my good theories. You will be sorry you ain't him.

 

[scull]

all the sculls are communicating telephatically...<br /><br /><br /><br />s--

 

[eric2006]

Yes, I've heard of that. Quantum entanglement communication medium. Thanks for keeping that break-through to yourself and not sharing it with the rest of humanity.

 

[scull]

The medium was known to your ancestors: a humanoid race called the Evians.<br /><br /><br />Vulcans shared this knowledge with the Evians millions of years ago.<br /><br /><br />--

 

[eric2006]

I'm sorry but I just don't believe in evianlution. I.D. for me.

 

[scull]

You should believe in evianlution: isn't your body made up of mostly water? <br /><br /><br /><br /><br />scull2006--

NO.<br /><br />Corona.<br /><br />With a lime <img src="/images/icons/cool.gif" /> <br /><br /><br /><br /><br /> Miles away from ordinary.
