Things i dont think people realize

They are actually calling it Spacetime these days. In other words relative to physics it's one in the same. Space is 3 dimensional and time is 1 dimension. This is true because without space there is no distance and without distance there is no time and vice-versa. It's more complicated than that I know but I'm a laymen and that's how I understand it.

What's mind blowing is when you scale these theorys/facts down. For example, when you hold your hand about a foot from your face, what you see is your hand back in time. It's only a micro fraction of time but still it is back in time! Crazy.

...I feel like this after reading that

Ha! That's awesome. I feel like that most days.

I deem this official soundtrack of this thread

(turn on the music before reading this... adds an effect...unless you really dont like it...In that case id have to kill all your cells at one time by killing a smaller amount of cells that complete your head. hah)

What i find awesome is the idea of going back in time, i remember that from a teacher that i surprisingly liked and was extreamly intelligent, he said in my words:

Everyone dreams of going back in time, i know i do, However its not all that simple. People think they can just walk in some machine and turn back the clock in the movies, its really not that simple at all. Changing time is the hardest thing, if its not impossible, that will be tryed. Because time is throughly an illusion, its not real, time is what we make of it. However the universal clock is completely the opposite. We dont make much of it at all, but in reality the clock of the universe is what we all follow. And to turn back the clock on reality and the universe is quite impossible. Heres why:

Since time is an illusion we can change it. We can make it go ahead, go behind, i can make my analog clock read "yesterday" as opposed to "today" but that doesnt mean squat. Because the fact that our time is based on a random location in europe and our calendar is based upon a man thousands of years ago. Its pure illusion and what we make of it. So on all our test this year we will write our name, although it is not our true name just the name decided by two other people what to name you, our true name is what we want to be called, however you will write your given name, the year (i forget the year but he said something in the millions), which of course is an illusion to us also, because what is time to us, we can only date back to dinosoars. And what was before the big bang? However the date will be (enter in some really old date in the millions of how old our universe is......

Then he went back on to say because time and date is purely an illusion to us how do we know what is what? Which leads to the theory of going back in time is impossible. However for one to truely understand they have to understand whats around us and what we make up. We are people. Placed on a planet. In a solar system, a system of planets based around a sun. In a galexy, the milky way, in a universe, our universe, which could be in who knows what. It has to end somewhere, but at the same time it doesnt, thats the beauty of it! Anyway to turn time back its not only what people were doing lets say 20 years ago, its the position of our planet, the position of our solar system, which is in the position of our galexy which is is the position of our universe which is part of no one knows. So to truely go back in time, one would need to go to the EXACT location of our planet which is in our solar system, which is in our galexy, which is in our unvierse, 20 years ago. So technically one would need to go to the exact place of our universe 20 years ago to truely go back in time.

This facinated me, and lost me, and i thought nothing of it, and for some reason 4 or 5 years later i remember vaugually. It was really a wonderful class. There was a bit more that i forgot, but ill allow you to think about that...



if the other song ended this to this one :)

and if that one ended listen to this one, i imagine this was being played while the big bang happened.

Oh another thing, our universe is merely bouncing between other universes, imagine very bouncy balls bouncing around a room of bouncyness, and the room is very small, and the balls almost fill the room, Each ball will go towards another and at the same time go away from another. When one crashes into it (a ball being a universe) it creats a crash (big bang, two enourmous masses of energy crashing together.) and the 2 balls go the other way, and crash into another ball, and this repeats and repeats... You can see how this is similar to our universe, however how do we escape our universe? I imagine that to be impossible. The mass of energy is so big and strong i imagine one would just be blown up and their engery shot out across the galexy.

And at the same time how do we know this to be true? People are wrong, We could be just a single thing in a system of one. We honestly dont know but we assume through reasoning and science that there is. just something to think about... I find the universe so vastly interesting because we will never know all there is to know about it. And its so vastly unimaginally big that we cant fathom the size in our mind (and yes its bigger then shaq... hard to believe eh)

@ Case, let's put it this way... if you were ever shot into a black hole you wouldn't even make it to the width of the earth's distance before you were stretched so thin that you were in celular single lines.

But comparing sizes... I must share these! First... an introduction by the amazing Morgan Freeman! :D



Now... to show how really insignificant we all are...

Wow im watching this now. I could listen to morgan freedman talk about grass and id listen

right thats what i found cool (what my teacher said)

That when we are looking at the moon we arnt really looking at the moon now, but the moon then. Its just a picture of the moon now, and the moon could be destroyed and we wouldnt know it for some time. And at the same time us looking at the moon when the moon is in the past is our present, so our present is looking at something in the past. However there is no present at all, in theory there is only future and past, It just matters how you determine your present. Its present if you define it within the illusion of hours, but almost no present if you judge by the smallest units of time. And that really were living in the future.

This is why i wanna study atronomy in college. Its so beyond facinating and no one really knows what is what we can only immagine.

@jazz

Oh I know haha I had to do a report on black holes 2 times for school stuff xD haha I actually learned something about them and ended up watching a movie called Event Horizon xD lol
That's exactly why I want to be tossed into one though...it would be the most metal burial ever! hahaha but it's more like a crushing atomic thing than a burial :P

I do love learning about the universe and theorizing about things(Pseudo-Philosophy)

@ EMB - check out a show called "Wonders of the Solar System" It's BRILLIANT! :D

I understand that... but it won't take very long at all for us to know if something were to happen to the moon... but if say something were to happen to the sun, or any other planet here then it'd take a much longer amount of time and distance for it to reach us.

The hand theory though about being the past doesn't really work because it's apart of us... if something were to happen to our hand, we'd know about it instantly. Unlike space.

Now... here's a question...

If a tree were to fall over in a forest - but no one is around to hear it; does it make a noise?

According to a physics teacher I had in high school(he also had the audacity to put pressure on my newly split chin at the time...football helmet+chin=pain and bone......), it would make a sound because of all the waves and such and his notion that it has to happen because if it didn't that would fault physics in all ways possible(he was pretty arrogant).

I personally don't have a direct response to that since well...there's no way to ever know, one can only theorize about things, like light:wave or particle? or both? why? etc.

Really interesting stuff outside the classroom though(I was bored to tears with the material, but my teacher also talked like Ron Burgundy haha)

Well thats just because the hand is so close to us were almost seeing it as it happens, Because light travels so fast and is so close we know almost instantly.

I say yes. Two masses collide, Matter collides, energy released, sound waves are released.

Also @Mac

Puppy!!! cute dog

Now back to the topic...Law of Relativity! :D haha

Yeah, soundwaves are released... but it isn't considered noise until it reaches the eardrum... otherwise it's just waves moving through our atmosphere. So how can we say that it made a noise?



Er... yeah! THAT GUY!!! OF COURSE!!!

@EMB5490,

That's because: People are living organisms that have senses to orientate us and tell us where we are in space and time. We use devices like clocks and calendars to tell us where we are in time. We use our eyes and other senses to tell us where we are physically in space. These are all perceived to be fixed references but they are not. All things in the universe from the smallest to the largest are consistently moving and have been since the beginnig. Therefore everything in the universe would need to go completely into reverse to actually go back in time. The problem with that is that there is no such thing as true reverse. Even if all matter all the way down to the subatomic level were to move in a reverse path they are still just moving through spacetime as they always have(I'm writting this and I'm just as lost as you are!). What's really cool is this: Say someone built a box and said it was a time machine. When you walk into it and turned around and walked right out you would be in the future!

I know, I have toooo much time on my hands! Pun intended.

@case211,

That was my dog Mac. We lost him last year and Kanga a few years ago. Incidentally, I decided to use his image in the threads so he could live forever!

Actually... a Ball is a solid, whereas these galaxies aren't exactly... Galaxies won't bounce off of one another - they'll either fuse together or create an extreme explosion due to too much gravity and dust concentrated in one area.

And (which I'm sure you already know but just wanna clarify) the big bang theory is that it was just ONE big explosion - where as I believe and so do MANY scientists that it was multiple explosions at different times - due to exploding stars, dust and gravity re-forming to create another explosion and so on and so forth...

Here's something to watch... which really gets me. About black holes and galaxies...



Yeah... the subtitles are just like "WTF" worthy but ignore them and watch the video. :)

Keep in mind that the definition of "instant" is an infinitesimal space of time. While our hand is part of us it still takes time, an infinitesimal amount of time, for the light to reach our retina, our brain to process it and therefore perceive it. Even lightspeed is a measurement of time.

Also, what we call space, as in outerspace, is the space between objects in the universe. Space still exist whithin the atoms of all things around us including ourselves. And remember, where there's space there's time!

He's a cute dog man...We just lost our puppy named Buster last week...I hate when animals die...
Sorry you had to lose both Mac and Kanga :(

I couldn't disagree more. Time is very real. It's all relative of course, but just because it is relative does not at all mean it doesn't exist.

I have to agree wholly with btimm man

I think the measurement of time is what we make of it, since without time, there wouldn't much of anything to base anything off of.
Time is really the one thing that allows things to happen at all. No way to go forward, then there is no way that anything can happen. No improvement, no development, no anything.

How we as humans perceive time is different though. Our brain perceives time as a video camera if you will. It is estimated to operate at roughly(some variations are there) 13 fps or so(I think, was a while ago I read about that).
So we perceive time sort of like a film, since our brain doesn't take in every single second and usually get's the jist of things down to memory, but not every single detail, which has an effect on our perception of time.
depending on what you are doing, let's say you are focused on one thing more than anything else for the course of 2 hours; you may not realize that the 2 hours you were concentrating on something(lets say you are jamming, and there are no clocks in the room) you aren't focused so much on time passing itself, like if you were in a boring lecture at school, but you were more concerned with what you are DOING and not what is happening, those 2 hours will not necessarily feel the same as the lecture for 2 hours.

Time is(In my opinion) the strongest force in the universe, since it drives everything(but not on a physical level of strength, that would be gravity).

I mean like 12:00 and 2:00 and stuff. Time on a clock is an illusion but real time like how we live and age and progress odviously isnt

Yeah, when you're talking about measuring time, that is purely a man made thing xD haha

Yeah, it's very real, and it's like what I said before:

We've created time due to the distance and duration it takes our planet to circle around the sun (a year) and how frequently we see it (days).

Scientists have also proven that due to the iceland volcano recently and the massive earthquake in Chili that our days have shortened - not by much (just a few seconds) but this proves that our planet is getting smaller. And that itself can alter time as we know it.

I feel that time is the 4th dimension of our world. It's hard to grasp this fact, but the thing is that we need to incorporate this 4th dimension for certain aspects of the science world to work.

I think it's string theory that says there are 11 dimensions in this world (at least that's how many it would take for the theory to work).

Evolution is really cool once you understand it as far back as you can.

Once you study dreams, you will realize that theres a whole new universe in your head.

Lol Its taken me way to long to find someone on here interested in quantum physics. I am currently studying quantum mechanics and quantum theory in general. In my mind, I feel the best way to explain why the general relativity and quantum world are so hard to explain the TEO (theory of everything) is because the latter is unattainable. Seriously, as we create unique and powerful new technologies (Large Hadron Collider in Switzerland-basically takes electrons and speeds them up to 90% the speed of light and crashes them together to observe the muons and even smaller balls of energy that make up our standard model of matter) we will never obtain a true answer... why? Because my theory poses that the human race will destroy itself before we figure it out, or that nature simply is infinite; meaning we will always find something smaller, and always find something bigger...

Example: back 50 years ago, scientist widely accepted that our universe was nothing more than the observable galaxy, with a few outside stars... farther back yet, it was only the solar system. However, we now think there are MULTIPLE universes, which explain some of the odder happenings of the universe ie. dark matter, dark flow, dark energy, and other singularities.

My overall take on how we got here is simple: At the middle of every black hole is a singularity... when black holes finally die off (yes recently evidence has been found of one actually getting bloated as if to blow up) they create such energy, that it destroys the current universe yet simultaneously creates the basic materials for new ones (which in my math beautifully explains the quick expansion and inflation of the universe)...

Morgan Freeman is a great populizer with science, along with Dr. Michio Kaku... but when you want to get into the deep stuff like the above, look towards Leonard Susskind (fought and WON the debate on hawking radiation and mathematical and logically proved that physics fundamental law of energy-energy cannot be created or destroyed-is not actually violated within a black hole).

If any of this confuses you, I apologize, science is one of the three of my passions (art, music, science). Look up Susskind and Dr. Michio Kaku... also look up Schrodinger and Keppler. If you are interested, I can go on all day answering your guys question about ANY thing in SCIENCE!!!!!

Dude! "What the Bleep" is one of my favorite films, ever heard of it? It's really quite good ;)

"What the bleep" is awesome. and being hammered and high while reading this is awesome. i've had these thoughts for a while and it's awesome listening to mastadon and thinking some crazy thoughts. thanks

Multiple Universes have been what I've been thinking of for a few years now... It really does make sense.

I don't believe in the whole "big bang" - but rather; galaxies and the universes have been made in pieces.

There's a book called "Why does E=mc2?" By Professor Brian Cox and it's definitely a great book for anyone to read - even people who don't know much about science can understand it. :)

@shred: thats a cool though, black holes always facinated me, i always wanted to be sucked up by one and ask the wizard at the center whats going on

In seriousness i remeber hearing or reading somewhere that someone said black holes were the key to unvieling the universe(s) and that theyre the only this where matter can be destroyed? is this correct? or doesn the matter become part of something else?

In a black hole the matter that is sucked in and crushed by the insane amount of gravity found there, is actually released back out into space very slowly in a different form. I forget what it is called, but it should be on like a site about black holes...

They are fascinating though, especially when you learn that the gravity is so strong that (if) you can sit at the edge of the black hole(Event Horizon I think?) and you have a friend sit further away from you and the black hole, you will age extremely slowly compared to your friends who might age 10-50+ years depending on how close you can get without dying and how long you stay there.

I love reading about this stuff ^_^

E=mc^2 is the exact reason why science will never pinpoint the start of everything. If you believe that matter cannot created or destroyed, then it always has existed in some form or another. They may try to pinpoint the start of creation (and fail imo) but they can't pinpoint the start before that start, etc.

Nevertheless, this has still been an interesting thread! :o)
