The relationship between time and speed/Possibility of time travel.
We all saw a bunch of movies talking about time travel, even marvel universe, such as flash and in superman movie, it says that they should move in the speed of light to be able to travel through time, but when I get to think about it. this is a wrong theory,If they moved fast, this only means they've slowed the time, but didn't travel through it, Einstein said that the faster you move, the slower the objects around you flow, doesn't this make the vice versa? which is: the slower you move, the faster the objects around you flow? can we really travel through future if we find a way to keep our bodies safe but slow? I think yes, but wouldn't really say that we will stay alive, as long as I know, I've seen so much cases about frozen people from ages ago, and their molecules are style fine, and their age seems to be the same, but they lost their life, can we travel to future if we kept our life in that position?
that also was a case in ''The last AirBender'' movie. that got me a little bit interested. even tho he could keep himself air inside as he was airbender, so he could live, but his molecules were frozen, and when body molecules/atoms are frozen, they slowly grow.
so what do you think?
is the possibility of a safe time travel real?
How do you think the relation between time and speed?

I guess this article explains who sees who slower.

And well, it's not "real" time travel as you said and it's not possible to go back in time with this method.
yup, that's my point of the wrong theory in the most of the movies that they can get back in time, which they only slow it, there's no way to get to the past, but there's a way to go to future, by slowing ourselves instead.

Actually for you to move forward in time relative to everyone else you are the one travelling extremely fast. If you travel at near light speeds time slows down relative to you, so light still travels faster than you by the same amount. By contrast time is still progressing at the same rate for everyone else, so when you are at normal speeds again more time has passed for them than for you.


For the case of organisms frozen in ice, the reason their bodies are preserved is that the ice inhibits oxygen from reaching the organism, so bacteria cannot live there and cause the body to decompose, so it is preserved
Don't dm me pictures of bowls that you find attractive.

did the humanity create something that can go as fast as light speed?

It's preserved, but you said ice inhibits oxygen from reaching the organism, since we need oxygen to live, their bodies will die,
but I think if we managed to find a way to feed them water,food and oxygen, that might work.

It is impossible, one of the fundamental laws of physics is that information cannot travel faster than light, that is to say, nothing other than EM waves can reach light speed. We have got things to near light speed though, such as large hadrons (protons, neutrons) in the large hadron collider at cern.

They were dead and their body got trapped in ice.
What could work? A person trapped in ice would die, its so cold and lack of physical activity would be another problem for him living, putting someone in ice is not a way to make them live longer

they don't die instantly.
I think they be in a kind of coma state, so they don't move around and pretty much doesn't feel, maybe some organisms will stop working but they will be just fine if they didn't stay so long, but that's For now impossible to keep someone alive in ice.

Well, Time travel is probably too hard for us to comprehend for now since it has to do with nerdy quantum physics and ultimate multiverse and timeline stuff and we dont know that much about it. I'd say time traveling in a single universe isn't possible, but maybe in another universe / dimension? maybe everytime we "time travel" we create an alternate universe where that one is affected, and ours is left unharmed, Once again, im too lazy to completely discuss this topic.
My skype is, Donovan Aldama if you wish to speak with me
yeah
This "slowing" business..did you mean standing stationary without any speed and acceleration? If it does, that mean every human being in this world has experience time traveling to the future.

I believe that by running faster than the speed of light which also beat the speed of sound, the runner will run in a voice proof dark space. If my understanding level of my class physic is correct, if you run on the speed of light, it would make a distortion length , area, and volume.

Here is my theory, usually time traveling are acquainted with accessing the fourth dimension.
This is my logic, two dimensional plane ( an area of space) is a distortion from one dimensional plane. While, the third dimension ( a volume of space) is a result from the distortion of two dimension. So to access fourth dimension would most likely by distorting two of them to create a new dimension and make time traveling sounds possible.

(Sorry if this may sounds a bit illogical, but this is my opinion and a bit understanding of some law of physic)

With slowing business, I meant simply that, the faster you run, the slower objects move around you, which was determined in most of the time travelling movies and such that the person himself moves while everything is barely moving the faster he gets that happened to be in the movie of flash and few time travelling movies, which makes travelling to the past impossible more than travelling to the future.
You didn't state your opinion about the possibility of future travelling though.
