so i had an epiphany on time a short while ago and about how time travel is impossible, due to logical reasoning and common sense (different discussion but pertains and backs theory). (the time travel toilet thread)
well i got to thinking about how lots of scientists think about time quite basically like Einstein did, EX. he had the theory that states when you travel at the speed of light for ten seconds away from earth, and looked back the time it would take for the light earth sends to that location would make the earth look older (or at least i think thats basically how it goes? feel free to correct me if I'm wrong). something also circuiting the internet about scientific theory's that say if someone travels the speed of light for ten seconds away from earth, then travels back at the speed of light, time would stand still for that person or go slower or some non-sense (again, feel free to correct me).
it got me thinking about a theory of my own on time that actually... makes sense? well the whole theory is basically that time is a solid, and that these other theories (along with time travel) are based solely on time being liquid, in the sense that it can be manipulated, isn't constant, or doesn't exist/ exists as a perception only. in my theory time is solid, in the sense that instead of being able to manipulate time or time being only a perception/ doesn't exist, it exists as a measure that started from the beginning of the universe. time cant be slowed, nothing can reverse/ escape the flow of solid time, nor can it change in any way.
reason being? first of all allow me to disprove (stopping, reversing, or slowing time) to a degree. because in this theory time is a solid, obviously it follows the same laws of physics and science as all other forms of matter. slowing time would require expanding a moment in time, for example lets say a person decides to try and extend three seconds into 5 minutes. it would be impossible, like trying to fit one atom into another (or jamming 50 Lego blocks into the space that one would normally occupy). there simply isn't enough room for it, because if there was enough room then initially that three second period would be five minutes, not three seconds. likewise, theory is supported in reverse (speeding up time).
secondly ill attempt disproving the entire notion of running the speed of light ten seconds away, then running back at the same speed, and being farther back in time than the locals (you being unaffected by time it would seem?). seems very illogical when going by the theory of solid time. quite simply, if you leave a specific location traveling the speed of light for ten years, then travel the speed of light another ten years to get back to exact starting spot, not only will everyone around you be twenty years older, but you will too. (even more simply put) even if you run really really fast, you still ran for ten minutes, and you've still been in the gym for ten minutes, just like the stationary fellows lifting weights who hasn't moved in a half hour.
Thirdly, i will attempt to explain this shananagins about going the speed of light for a while, then look at earth and see a much older earth due to the waves of light taking however long to get there. first of all, you just traveled there in record time, what makes you think the frigging light itself wouldn't be able to get there at the same time as you? B= traveled to there to view the earth, 30 seconds going the speed of light A= earth -------= light...traveling speed of light __________= you traveling at speed of light
B---------------------------------------------------------A
the light is already being sent to point B, then you arrive there at the same time. you both traveled the speed of light, so someone would need to explain to me how the earth magically looks older, considering the images seen are from the time you depart...
questions? general thoughts?
EDITED side note: its not literally solid, it was implied as a metaphor...
(to nobody in particular) if being a complete a**-hat is your opinion, then state it this is a subejct that would help a lot no matter what you say, even if its along the lines of "STFU NOob" *teabag*

Eh... Your example about being 20 years older doesn't make sense according to the Theory of Relativity.
Time (and some other things, I believe) are relative according to Einstein. If you are traveling at the speed of light in your little lightspeed pod and you look at your watch and you've gone at the speed of light for 10 minutes one way, then you go 10 minutes backwards so you end up in the same place you started. Okay, great. Light travels at 300,000,000 m/s^2. That means that light travels 300,000,000 meters a second every second. It's a constant.
So there are 600 seconds in 10 minutes. That means that in 10 minutes, traveling at the speed of light you would travel 180,000,000,000 meters. That's a long-a** distance. Anyway, according to the theory of relativity (and this aspect has been tested, if I'm not mistaken) your 10 minutes at light speed equates to much, much longer at "regular" speed. A thousand years could pass outside of your little time dilation bubble, but inside that time dilation bubble, created by you moving at or near light speed (which is considered physically impossible, btw), you have just aged and experienced 10 minutes.
It might not make sense to you, but relativity makes more sense to me than your "solid time" idea, as time doesn't actually exist except as a measurement. There is no substance called "Time", it's just the measurement we use to tell how long it takes to get from one point to another.
My two cents.

Time, like light it can be distorted by gravity (like black holes). Also, time dilation occurs more often than you think. Look up Fotamecus. He is an egregore created for the express purpose of cramming five minutes into three seconds and vice versa.

... I just skipped to the part about B being light travel something. o-o This is freaking confusing to me. I don't get it (mainly because I only read a few sentences and was like "..."

aki7the7worried ... I just skipped to the part about B being light travel something. o-o This is freaking confusing to me. I don't get it (mainly because I only read a few sentences and was like "..." i think reading the whole thing would help a lot but if i explained it more vividly i would take up too much room and then people will ignore it all together.
