View Full Version : I dont understand the universe

so i watched this thing on history channel
the way i understand the big bang is there was a highly dense ball that exploded
and we are still in the after affects (the out ward expansion of the universe)
eventually everything will stop moving out and come back together and reform the ball
did atoms themselfs get wider during this?
do atoms hold the same physical prinsipals of the universe (nucli-suns planets electrons)?
what is radio carbon dating?
is big bang creationism on a larger scale to account for a god?

The Big Bang was NOT a single point of light that exploded... it was an expansion that happened everywhere at the same time. In all likelyhood we are the result of a former universe collapsing on itself or the result of a collision between two other universes.
And get this, in an infinite universe, the odds are better that our universe is the result of a creation of someone else. I'm not talking god, I'm talking The Matrix style.
The shows you see on History Channel and Discovery are good, but water down explanations.
I highly recommend you read this book: The Elegant Universe by Prof. Brian Greene (http://www.amazon.com/ELegant-Universe-Brian-Greene/dp/009928992X/ref=pd_bbs_sr_1/002-9909797-9878455?ie=UTF8&s=books&qid=1189014747&sr=8-1)

What that means is the farther you look out into space, the farther back in time you look.
All the stars we see in the night sky? What we're seeing is their light from thousands, millions even billions of years ago. Many of them have burned out, but we'll never know because the light from them will continue to reach our planet for thousands of years. There is still light from other new born stars that haven't reached us yet.
Even when you look at the moon, you're seeing what it's surface looked like seconds ago - I think it's a seven second delay.

not at all. it means light has a speed limit, and by looking deep into space, we are looking "back into time"
think of it like this.
you are watching a baseball game, but from the deep outfield. someone hits the ball. you see it happen. then 2 seconds later you hear it. the sound and the action are 2 seperate events to you. to the catcher, both things are 1 event.
sound has a speed. just like light does. so from the vantage point of earth, everything we see now is from the catcher standpoint. and we look deeper into space, we are like the fan in the outfield observing space as it was billions of light years ago.

It can be hard to wrap your brain around it - in fact, I saw Brian Greene give a lecture this year and he used that exact phrase because as you tell any of simple facts to a group of people, there is a tendency for all to laugh. Whereas, you'll look at the guy next to you and see that he doesn't get it either so they'll have that common bond to just say "That's crazy" and walk away. Saftey in numbers.
But, if you look into this stuff yourself, if you really do the research, you see that it's not at all impossible, even if you do feel it improbable.
For example. Is the universe infinite? Right now, the simple facts that we have tend to point to: Yes, the universe in infinite.
We are all a result of certain atoms and forces, such as gravity. We're put together in a certain way that creates our existence.
Now, in an infinate universe, it is a mathematical possibility that these same kind of atoms and forces will get together in the same way. That means, somewhere else, there is another you. And that means there is an infinite number of "you" elsewhere in this universe and parallel universes. There can be subtle differences throughout the infinite "you" - different colored hair or even wearing a different colored shirt - but they're out there - in an infinite universe.
Now that is hard to wrap your brain around - but it's the human ego that prevents most of us from ever fully embracing it. But think about it - how many times have you seen someone look or act almost exactly like someone you know?
Now I wouldn't even attempt to compare that to an infinite scale, but we're all made of the same stuff, and mathematically speaking, we will come close to duplication and repetition. It's just the laws of nature and physics.
Then again, there could be different laws of nature and physics in other universes, and even more closer to home, other galaxies. We just don't know yet.

ironically, it's einstein's theory of general relativity that leads to the Big Bang Theory's formulation. His special theory of relativity is the one that prescribes light as the universal speed limit.
The most important aspect of GR is that space-time is curved. This is a difficult concept to imagine in 3-dimensional space, but there's a mathematical thereom that proves that a curved 3D space can be embedded in a 3D-space :-) (A curved 2D space can only be embedded in a 3D space, so it's pretty significant). John Nash actually did some work in that field (guy depicted in a "Beautiful Mind").
Black Holes represent regions of space that are curved so much that no path can take you beyond the event horizon. The Big Bang was kind of like an unfolding of an intensely curved space such as that. The entire fabric of the universe and all of its energy were contained in a singularity that unfolded into our universe today and that continues to expand. As the energy level dropped, the different laws of nature began to appear, and finally the universe that we see today came to be.
Atoms didn't exist yet, as the universe was too energetic for them. They're held together by two forces (nuclear force in the nucleus, eletromagnetism between the electron and the nucleus), and also the protons and neutrons (which are composed of quarks) may not have been around just yet. Also, heavier atoms are made in stars through nuclear fusion.
And please don't ever compare the Big Bang to creationism...

This may be a little intense, but it goes through the Big Bang timeline. It helps to know that first, everything is a form of Energy. Photons, electrons, quarks, pions, whatever. Second, they all interact through quantum mechanical fields. String theory and other Grand Unified Theories, or Theories of Everything, assert that at high energies, all forces in nature (Strong Nuclear, Weak Nuclear, Electromagnetism, Gravity) become the same single force. As the energy drops, the forces begin to differentiate themselves. That should get you through the first instants of our Universe's history :smile:

bada-bing!
and now the dork factor...radio carbon dating is based on the accumuation of carbon atoms into living organisms. As living organisms they take up nutrients from theri surroundings and incorporate these nutrients into their body. This incorporation changes the ratio of carbon that is "unstable" (radioactive carbon, carbon14 I think) to stable carbon isotopes with respect to the organisms surroundings, i.e. the environment, where radioactive to stable carbon ratios are for all intents and purposes constant. Now, when an organism dies, it stops accumulating carbon, both radioactive and stable. Now, since radioactive carbon decays at a fast enough rate, we can analyze the amount of radioactive carbon in a biological sample and thus the ratio of radioactive carbon to stable carbon will give us the approximate time when an organism died, i.e. it stopped accumulating carbon.
Please step in and critique this explanation (I'm looking at you Zentraed), it was off the top of my head and I would love to hear anything furhter on it.

From what I understand, the claim that researchers (I think both from Germany and Japan) have observed particles moving faster than the speed of light is based on Schrodinger's uncertainty pricinple, in these cases it is refered to as quantum tunneling. An atom is "shot" along a specified course. This course contains a barrier assumably impenetrable to electromagnetic particels, i.e. an electron, that the particels are routed around with the use of magnets. The particel detector is placed just behind the impenetrable barrier and the particles travel in a series of 90-degree turns around the barrier. What these researches claimed to observe was electrons hitting the detector before it was physically possible for the particles to travel the disctance around the barrier, i.e. three sides of a square compared to a straight line. The idea is that, the electrons behave as a quantum of energy, as such, theri exact location can only be described by a statistical equation, it can never be truly defined. Thus what these researchers claimed thay were observing were the electrons at the far ends of the bell curve, those that had "tunneled" through the impenentrable barrier.
The experiment is highly criticized I think, but amazing none the less.

i never watched it because of this line "
The theory basically postulates that electricity, and not gravity is the binding force of the universe"
gravity is the weakest of the atomic forces, and electromagnetism is much stronger than gravity could ever be. just like how we can pick up metal with magnets, even though we have gravity on the planet.
