Time

[beavis]

Why do you ASSUME time is infinite? There is an END OF TIME (I mean that literally) in the center of our galaxy, a black hole.

Hiya No leaf,
Another interesting topic. I didn't read the post on the theory as I have been building my web page, but would like to get in on this subject.[]

I did see a theory that suggested all moments exist as one thing called time. And in my own experiences during Soul journeys to other lives of mine, I found that it is pretty damn close to the reality.  What I learned was that each moment existed as a present reality no matter where or what 'time-frame' I was in.  So I penned a quote to describe it..."Time is only relative to having a perception of it."

There are other philosophies that say we are creating each and every moment anew, and that past and future do not exist except as thoughts in our minds. So, if I saw a car I liked on the road, I could not be sure it even existed once it was out of my sight, out of the moment that I was creating!  I really like this concept as it appeals to my preference for a lack of structure. LOL. Who knows, maybe the mentally insane aren't insane at all, maybe they are sinply living other realities that are dependant on their time-frame creations!!!

I'm looking forward to reading what others have to say on this excellent topic of yours No leaf. []

Love always.

I was just throwing out an idea. I don't really know that much about space or time and I wouldn't be surprised if it fell apart in the face of something as simple as an apple falling from a tree (but maybe not that example literally). But why do you assume there is an end of time in a black hole?

[beavis]

I did not assume. I took a class on spacetime and know in detail the time structure of a black hole.

Beavis,

Even if you did take a course, how could anyone say for certain that time does or does not exist in a black hole.  No one has ever been able to take measurements inside of one.  Therefore how could we ever hope to say what one is capable or not capable of doing.  It is entirely possible that the inside of a black hole is complete nothingness where even time does not exist.

[cainam_nazier]

Time is only relative to the idividual or the grop perspective.  However one individual or groups perspective of time can differ from anothers.  So using this as a basis can we even say that time exists?

Also if time is truely infinite, meaning that it is infinitely large and infinitely small at the same time, can it exist?  

Only that which has a desernable begining or end is can truely exist from our own perspective.

Since time has neither, it can not exist.

Well, what you said about time could also be said about space. A line in space creates an infinite number of points. Even if you divide it up to the atomic level, there will always be more space in between. I don't like referring to time as the 4th dimension, because our definitions of 1, 2, and 3 exist in the spatial domain and time does not. However, time does indeed behave like a spatial dimension. If you compare width, height, depth, and length (in time), they all have the same essential properties. They all create a line if a point is extended in their direction. They are all independent dimensions at right angles to each other. Each acts as a coordinate to define the location of a point.
So.. yeah. I don't know where I was going with this. X|

Hey Tayesin.. You posted while I was posting a reply, too, and after I posted I didn't wait for the page to reload, so I just saw your post for the first time. I like a lack of structure too, a lot of the time. [] It seems like the physical is the most intricate place in the universe.. and from the astral on, things just become more simple.

[TheLunatic]

I don't really feel that time is infinite. The universe had a starting point. There are two main theories to how it will end as well.

The first, which I hold to be true is that there is enough gravitational attraction in the universe to cause it to stop expanding and collapse inward again. The other theory is that it will grow larger and larger forever ending in a cold dead empty lifeless universe.

If you look at an element like gold or iron. If you break it down far enough you get to an atom, which is the smallest part of that element you might have that is still that element. I feel time and space are the same. Human's might never be able to see down far enough to see an atom of time but it's there nonetheless. Alot of different theories about space say it's full of little things called super strings....

Basically I guess it really doesn't mater in the end. Science is just like a religion. You just can't be 100% positive about anything it says.

I also think the world is really flat and that the 3d dimension is a lie told to keep us in our place.

The smallest known unit of time is a "quantum wave function"

[TheLunatic]

Hummm I've not heard of that, sounds awful mathematical. I'm somewhere between a laymen and a theoretical physicist. I've always enjoyed learning about things like this but I've never felt the urge to start messing with the equations...

I don't like math problems with lots of Greek letters, they make me very unhappy.

[beavis]

Its not complicated. A quantum wave function is just a sine wave where the absolute value of the height of the wave is the probability you will find a particle in that space.

probability = | sin(position) |

[TheLunatic]

O! Humm sounds like there are 12 more pages of equations to go along with that somewhere though. heh.

Quantum theory is pretty cool stuff.

[beavis]

There might be 12 pages of equations other than that. Thats just what a wave function is. It applies to all particles.

[TheLunatic]

All particles or just sub-atomic particles? heh...  But yeah I think I understood the basic idea of the equation. Pretty nifty stuff, some times I wonder if I should have took the science road and not the computer related one...

Lunatic "science road and not the computer related one"

I'm a computer programmer. I took both roads. A few physics classes and internet reading.

[beavis]

"b is the electron amplitude"
"n = 1, 2, 3, 4..."
"[wave function] = b sin( n pi x / L )"

I was talking about constant amplitude. N (energy level in the atom) can change, but will usually return to its original position really fast. L can change if the particle interacts with an outside force, but I did not try to account for that.  N  B, n, pi, and L are all constant, leaving my original equation for a particle not affected by outside forces:

wave function (probability) = | sin(x) |

It was meant to give a general idea of a wave function, not to calculate it in combination with other things.


Why are you posting in a thread about time, timeLESS.

[beavis]

My act was choosing to react. We were giving equations for different things, and I wanted to explain that so people here would continue to listen to me about physics. hehehhe hehheheh hehehehhehehehehehehehe [/stupid beavis laugh]

[beavis]

What is the size of a planks length compared to the smallest wave function wavelength?

[beavis]

Is the smallest wave function wavelength bigger or smaller than 10-44 seconds?

[goingslow]

You go timeless []

I enjoyed reading that.

[beavis]

timeless "Wavelengths are measured in distance (i.e. metres, m) not time (sec.)."

C = 1 (no units)

Can you figure it out now? Dont forget to use the correct size of the smallest wave in all spectrums. If there is not a smallest wave, then I am right that a quantum wave function is the smallest unit of time. If there is, what is its size and how did you calculate it?

"Gamma rays are in the 10-15 m range on the electromagnetic spectrum."

Are you afraid to use the other spectrums?

"Atomic time is shorter than the time it would take for any wave to oscillate"

Obviously you cant measure the oscillation of the smallest wave directly. What smaller thing would you measure it with? A different method must be used to determine its size.

[fredhedd]

ha.  you guys are funny.  you are all missing the point. no leaf clover was just asking what time it was.  it's now one thirty pm, no leaf.  i didn't go to college.  have a nice day.

[no_leaf_clover]

Thanks, Fred. [] I should get a watch.

[beavis]

timeless "Visible light is measured in nanometers (10-9) all wavelengths are measured in distance."

Thats as rediculous as measuring height in inches and width in centimeters. I'll give you the conversion since you didnt take the hint in the last post. 299700000 meters = 1 second. Any distance can be measured in time.

"Third year physics is when you start really getting into this stuff"

I learned about spacetime in a third year class.



You assume the electromagnetic spectrum is the only spectrum. Many people here at the astral pulse should agree that there is at least one higher frequency (therefore shorter wavelength) spectrum you are ignoring, the astral spectrum.
