Is the concept of spacetime logical?

[makaveli121212]

no, it just isnt intuitive...physics people made the equation and it works and the expermients prove it works but they really cant explain why it works, we just dont look into it...similarly to things at the atomic level...it isi known that electrons move from point A to point B, but how they get there is a mystery, and researchers have given up trying to find out...there is no real reason to understand why because it just is and the equations work the way they do

and researchers have given up trying to find out

ummm...everything else was right, but there is definately still research going on in particle physics and special relativity.

[makaveli121212]

well that was talking about electrons and no there isnt much research going on there at all...some, yeah sure, but it is regarded as fact and it is unexplainable so it is left at that

Well, thanks for your thoughts, this topic is almost dead. I'll try to think of something else that will be interesting.

[Jello]

ill bump this topic because i want too. Ill just say one thing. Time is a constant just like the maximum speed of light is. Think of it this way. if you are travelling at the speed of light and you have a flashlight that you shine in front of you, Is the speed of that light protruding out of the flashlight going faster than what you are travelling at? the answer is no because speed is relative. the light shining out from that flashlight is moving away from you at 186 000 mps (miles per second). it is moving that fast from your stand point. so time has the same concept to a degree. Time might be different for you than it is for someone else. but time is a constant based on your perception. ie... someone in gym class will have fun and go through it "quicker" then you will in your math class because they are enjoying it. it doesnt mean that time has sped up for them.. it just means there perception of time is different.

I have got to be honest with you guys and I know this is a little behind, but after having read all that has been posted I feel like so smrt.

Sorry about that guest thing that was me, afrobean (just incase im not logged in again; I'm not sure)

Take two hypotetical plots of land with grass on them. Say a black hole were to spawn on one field and somehow not effect the other.

If I were to stand on the empty field (field A), any object being sucked into the black hole would appear to move at an incredibly slow rate.

If you stood on the other field (field B), things would be sucked into the hole at a rate you would expect crap to be sucked into a singularity, yet I would move extremely fast.

Ignore the fact this example is completely and totally impossible to witness according to physics, please. Does this mean that time moves faster for me on field A or slower for you on field B? Nope.

Simply put, time is relative. What you experience and what I experience have absolutly no bearing on each other.

Ignore the bad pun, too.

Time is relative. The entire universe could slow down and we wouldn't notice it, because we would be slowing down too.

[Afrobean]

Oh my god, perfect fat is a friggin genius!
I'm not even being sarcastic they made this whole concept make about 5 times more sense.

[makaveli121212]

but if we were slowing down wouldnt days last longer and years be longer

[AlbinoLime]

Makaveli.....you don't grasp concepts easily, do you? The guy said "Time is relative. The entire universe could slow down and we wouldn't notice it, because we would be slowing down too."

Lemme just repeat one part of what he said, just so it will sink in, "we wouldn't notice it"....

The days would last "longer", but if the universe slowed down (and everything in it (including time)), then the days would still be 24 hours. It would just be a longer 24 hours than it was when the universe was faster. Get it yet?

[Specforces]

Prove it.

prove what?
