Space-Time and the Accerating Universe

Ive been thinking about this alot lately. imagine if no living beings lived in the universe. that would mean time wouldnt matter if you were inanimate. energy gets stored in matter and under certain circumstances it is released in ALL directions and in different wavelengths. the difference would be that it would be more particles attracted to where there are already particles that attract that charge. why do they think that the vacuum of space is absolute (the speed of light is constant in a vacuum)? there are black holes and other objects with massive gravity that show that light can be, and is, bent. now picture the stars in the sky. we can see their photons. that means that charged particles are reaching our side of the solar system. the expanding universe hypothesis says that the red shift from distant galaxies are getting dimmer. im not going to argue with that. but there are people that say that it is accelerating. our milky way center is becoming more active. this means that the net force attracted to the center is increased and therefore is distributed throughout our whole galaxy. that would probably make the red shifts dimmer while at the same time accelerating our own galaxy even perhaps even our solar system (causing us to percieve time faster). i personally dont believe that we will have a theory of everything because its like solving an equation in all directions . but i do believe that we can get relitively close in a "closed system" although it is not that closed.

how do we know the speed of light when speed = distance over time, where time is just a perception? we don't.

sorry for the grammar and spelling. my thoughts are faster than i could articulate them into words, and it would take me a LONG time to correct it all. So that are just my thoughts on space time and the acceleration universe.im not saying im right but this is how it makes sense in my brain

I don't really follow much of your logic.

light is known to bend in extreme gravity fields.

try livescience.org or some other site where they describe quantum physic or anything so you can get a grasp on what you are asking

dr quantum on youtube isnt a bad resource for beginners

edit: i dont know why us being here or not would change the universe in any real way other than earth and the surrounding areas wouldnt be polluted with garbage

According to quantum physics there would be no universe if someone wasn't 'here' to observe it... You know, just like... If a tree falls in the woods and no one is there to witness it, does it make a sound? Personally I don't buy it!

It may help if you articulate yourself in digestible paragraphs. There's a lot going on in there! Also in regards to experiencing time faster, we would actually perceive it to be slower the faster we accelerate.

I believe everything in the universe affects the universe and its expansion. look at colors for example. we know that black attracts heat and white doesn't attract as much. also keep in mind that energy can only be transfered. so the energy that goes to one object didnt go to another showing that even the littlest things in the universe can effect the formation of the universe.

infrared, when i said "causing us to perceive time faster" i meant causing us to perceive the expansion as accelerating. time would appear normal around us , but more time would pass by (outside) in the same amount time (inside).or slow down(inside) and the same amount of time passes (outside). it depends on the frame of reference. sorry for the mix up. now off to deal with the headache.

But these cosmic red-shifts are distorted by the motion of galaxies themselves, for example due to the gravitational attraction of nearby objects. The amount of distortion therefore provides a measure of how quickly structure formed at a certain time, which in turn depends on the energy content of the universe and also on whether general relativity is correct.

edit to add:i just found this article right now and explains it alot better.

i think it would still exist. just fine indeed. and a tree falling does make a noise, as long as it hit something as it fell. also the cracking of the tree (assuming it was broken from its roots in order to fall would be pretty loud if you were within radius to hear

BUT

if we werent here, nothing would change. There was a test recently that proved that it doesnt have to be a human witnessing the photon to change it to a particle. other particles can also "observe" and thus change the properties. so living or non doesnt really matter to it. just as long as something relies on some kind of answer from it to form its direction/essence

YET

one of my favorite quotes is: The faster you go, the longer you live.

of course that is relative to things that arent going as fast as you. but you age the same to you as you did when you werent going fast so how would you tell. leave earth going lightspeed for 2 years, and come back the same speed. 2 years away + 2 years back = 4 years total. but because you were going so fast, you aged 4 years, rest of world aged like 20 (im making numbers up).

this was proved with 2 atomic clocks, one of which was in a satellite, the other on earth. satellite clock came back with less time passed.

MOREOVER

people say the universe is expanding at an ever increasing rate. its expanding faster and faster which is completely contradictory to what we know when we see an explosion. pieces slow down as they encounter friction (air, buildings, people)

if we were here at the ends of the universal clock. we would be accelerating so fast from everything else in the universe, that the image of stars and galaxies would dissappear. they would be going so fast away from us, that light cant reach us. kinda like the event horizon of a black hole.

we would perceive nothing else outside of our little bubble the heliosphere. we would in fact think that we were the center of the universe because we couldnt detect anything else.

we would travel in this manner until time literally stopped. if the faster you go the longer you live, then we would be going so fast, we would live forever. BUT ITS RELATIVE. we wouldnt know we were living forever because time would seem like its our speed still. an outside observer would (if could) see us blazing past.

and actually if we were in that situation, forever is VERY relative, because we would actually die very soon, since the universe would be OVER.

BACK ON TRACK

you say

1. if we werent here time wouldnt matter.
Time already doesnt matter. its nothing. depends on who you are where you are and what you are next to (gravity matters big time) and if you actually keep track of time....

2. time doesnt affect inanimate objects.
just as beaches erode and mountains crumble. the amount of time these objects are left to the elements, matters a great deal.

3. particles would be attracted to each other much more than normal, because we arent present.
particles are attracted to each other already, as long as there is an adequate force for attraction. our presence (or lack thereof) wouldnt change this.

4. vacuum of space is absolute.
is absolutely what? if you mean absolute space time, then you have a mix up. absolute space time is a theory of isaac newton and doesnt work in todays physics. we know more now. his physics worked then. just like we know a whole lot more about gravity (and its that we know nothing really).

5. light is and can be bent.
true. this goes back to your speed of light highlight again. light (speed of) is bent when you yourself goes super fast, or it encounters lots of gravity.

6.photons are charged particles.
they arent. photons have no charge. positive or negative. they are neutral. charged particles are reaching us, and are already here, but they aren't photons.

as for the rest, I'm still really lost what you are asking.

Do you want to know something? or are you explaining that you perceive something different than scientists claim?

I wouldnt have wasted all of this time responding if i wasnt trying to help
just be more clear. USE PARAGRAPHS. 2 different directions of thought need to be split up.

Einstein said that if he had to solve the end of the universe, and it was 1 thousand years away, then he would need 999 years to define the question in its entirety, and use the remaining year to actually solve it.

figure out what you are asking before you try to solve it.

I apologize that I haven't replied. I left ATS for personal reasons but i decided to come back.
Anyways, I really wasn't asking for anything and I apologize for any confusion. I originally only wanted to post about the expanding universe then i went on too many tangents. I wanted to point out that time is irrelevant when it comes to the universe. Matter just gets recycled.

Actually we where talking about the expanding universe in the Science of God thread not too long ago (I won't go into that).

I think the question that hits me the most is.

If you fire a gun in space with a muzzle velocity of 2200 meters per second, it will continue on that path with no friction at an exact velocity of 2200 meters per second (with no outside forces).

If our universe is accelerating, what exactly is pulling us into the vastness of nothing?

reply to post by DaMod


I do believe that the universe is expanding but I think that it is accelerating if we are indeed passing through or by the galactic plane, however the acceleration would decrease as we move away from it.

Now for your question, the problem is that there will always be outside forces. lets say you shot the gun in a black hole. even if it is traveling a 2200 m/s gravity wouldn't let it get far. i think the very same universe is pulling the VISIBLE universe. as to what is pulling the universe as a whole, I have no idea. probably a fifth fundamental force, in my opinion.

a lot of people claim dark matter and dark energy are the reason why its accelerating.

dark matter is also how galaxies are supposed to be held together. the gravity from the center of the galaxy isnt great enough to hold all the stars and pieces spinning around the center.
