so is time irrelevant outside earth?

The speed of light is constant, so no matter where you are you can measure time by how far a pulse of light has traveled.

You'd still need a unit of distance, which would be arbitrary, but you could measure time.

 

But you also have to think of the expansion of the universe. That's what redshift is and if it's expanding outward, is there new matter being created or just stretched?

And if it is new matter created, it's a contradiction to newton's 1st law, which is what holds the universe together in the first place. whole shit's fucked up there man.

 

IMO I believe newton's theory is wrong. if matter couldn't be created or destoryed, we wouldn't be here, the universe wouldn't be here and there'd just be nothing. Matter has to come from somewhere, they just don't know how it's done.

Lets see if the hardon collider can figure it out. lolz.

 

Time will be perceived the same on other planets, but the measurements of time would differ due to planet's rotation or length it takes to revolve around it's sun.

Like, check it: If you were on Venus, a day would be 243 of our days (24 hours x 243), and a year is 225 days.

If you were in space, time would still go on as normal. You just wouldn't have days or nights.

Now, the perception of time could be drastically different in another Universe or even dimension...

Word.

 

They're already pretty sure about this, it's described in Einstein's E = MC^2 equation.

There is a relationship between matter and energy, and matter has been observed being converted into energy and back again (the process is called annihilation and decay, annihilation is when matter and antimatter collide and create energy, which can then decay into pieces of matter).

The problem is, the expansion of the universe isn't slowing down, even though gravity should be slowing it. This means that energy is somehow being *added* to the universe. That's the real problem, if energy is being added, where is it coming from?

 

fuckkk this shyt is giving me goosebumps lol, out of curiosity what exactly do black holes do? does it just pull something further and further away from the center of the universe or actually consume the matter???

 

It's really irrelevant since time is only a concept that was developed to let us know WHEN we are. Even if we were on another planet we wouldn't need to know the time/day unless we were staying there for an extended period of time, at which point time would then begin at 0 hour of 0 day. If you go to prison and start putting tally marks on the wall do you make a mark for every day you've been alive, or just the days you've been there. (That's obviously a silly comparison, but it makes my point.)

Your problem is that your thoughts are relying on the idea of creation. This is exactly why people feel the need to believe in the concept of time. Because we are creatures that are born and die we see everything as having a beginning and an end. Even in the furthest stretch of our imaginations when we try to imagine time being infinite we imagine a beginning and an end. We have to accept the fact that there may have never been a beginning, things just were.

If I stretch out a rubber band have I created matter? No. But there will be a larger area inside of the rubber band.

 

espn, google ANATOMY OF A BLACK HOLE its insane as fuck.

 

that was a crazy read bro

 

If there wasn't consciussness in the universe time wouldn't exist..So to me its made up

 

You haven't created matter, but you have created potential energy. Once the rubberband is released kinetic energy is being "released."

To the poster asking about black holes: a black hole is an area in space that nothing can escape (no mass, no energy, no light). I'm pretty sure that it is fairly accepted among the scientific community that a black hole will form from a star collapsing on itself, but I don't think that is the only way they can form. Because a black hole absorbs any light that hits it, no light is reflected off of it and therefore can't be seen. Black holes do (theoretically) emit radiation however according to some of Stephen Hawkings theories, and that is pretty widely accepted also. So, in a black hole does time still exist? I speculate (this is purely speculation, as I have never been inside a black hole) that sure, "time" exists, but it would probably be pretty impossible to measure.

I think that time is universal, but the measurement of time is a man-made thing though. We just happened to base it on naturally occuring events (the earth's rotation, lunar cycles, solar cycles, etc...) It is obviously useful to know that is 10:35 on January 24, 2010, but that's only b/c we've made our lives so difficult and complicated that we need to plan and schedule our daily lives. Back in the day nobody cared what hour or minute it was, people measured time by how much daylight they had to get their work done, or how the seasons affected their farming or whatever. But they still used lunar cycles and the such. So, in space time would still exist, but the way we measured it would depend on A) where is the universe we were at, and B) what we were spending our time doing. If we were on another planet, I imagine we'd still measure a day by a rotation, and a year as a revolution...if we were trying to farm or plant something, we'd probably still use the lunar cycles but that would probably take some trial and error or some pretty advanced technology and theory to get it right since the moon(s) of each planet vary in number, size, density, distance from the planet, composition, etc. If we were just floating around in darkness on the other hand, then we probably wouldn't care too much about what time it was.

This is the kind of stuff that I think about all the time.

 

Time is solely relative to the observer and their position in the universe. At our point in time however, its not possible to notice the difference very easily. Time is relevant you could say outside of earth, but, like I said, observers will notice time differently than other observers in the right circumstances. The twins paradox is pretty interesting, same with time dilation, and other similar subjects. And to people referencing to newtons laws, on this scale Einstein's general relativity is the more accurate theory. Which also disproves an absolute time, and position, meaning, time and position will always be different to different observers.

 

Gravity's power decreases over distance.
What gravity would slow it down?

 

The gravity of everything in the universe.

 

That is where dark energy comes into play I believe.

Apparently, a vacuum of space has energy, and its surprisingly a fairly large number i think...

 

damn i thought i was going to be clever and post it first but it seems i was beat to the punch line

matter can not be created nor destroyed. whoever said in the post of them not knowing how our matter in our universe was created they have, its in Europe and they do tests all the time sending energy at eachother to create small bits of matter, but thats saved for another day.

When we didnt have matter, empty vasteness, we still had potential energy. any space has it. - thats my opinion yo

 

Have you read A Brief History of Time by Stephen Hawking? He explains that since there's no matter, mass, light, etc in a black hole that time cannot exist for that reason. If there's nothing to measure time by, it cannot exist.

know what ima saying?

 

Not exactly true, and yes I have read the book, and he explains it a bit differently. I don't know about matter being inside, because I don't know how one could test that the matter stays in, though blackholes do give off radiation so that would make sense, matter being inside that is. There is light inside a blackhole, the gravity is just so strong that it curves the light so much it ends back up at its original point, therefore, you can't see it. And time technically does exist, except you wouldn't notice that time outside of the event horizon with an observer going into it, only the observer would think it was going at a normal rate.
