Yes and no. Everything is relative, including time. Time in one location is not moving at the same rate as at another location. We will call the rate of time's advance on earth the base time, t0. As you speed up, the amount of time you experience, t, is represented by the equation t = y*t0, where y (actually the Greek letter gamma, which looks like a y but sounds like a g) is the Lorentz factor, y = 1/SQRT(1 - (v/C)2) where v is velocity and C is the speed of light in a vacuum, 2.997*108 m/s. As you get faster, the Lorentz factor increases, and the amount of time you experience becomes longer and longer compared to the amount of time on earth. When you reach the speed of light, time on earth virtually stops, and you continue moving through time. This begs the question, if you go faster (forcing the Lorentz factor into imaginary numbers), do you go back in time? Maybe, but such speeds would destroy matter on the atomic level, so it would be difficult to find out.
They believe that they CAN NOT travel backward in time but they think they MIGHT be able to travel foward in time (to the future). Improving the answer:
The reason why you can't travel into the past is because you even, existing there will change the future. (For an example: You being there, someone will see you and might think something they shouldn't think because you dont exist there. That will change what they'll do that day, any what they'll do in the future because that moment they thought something they should've been thinking something else.) This comes from the grandfather paradox (going to the point of time where your grandfather hadn't concieved your father and killing him). Therefore you wouldn't exist. That'd mean you change the past which changes the present time (which is the future then). Even if you were to timetravel into the future, it would have to be a time where you don't exist (as in, you would already be dead then), and you wouldn't be able to ever come back to the present time. Why? Because even having those memories of the future, you're bound to tell someone which would change their opinion. You can timetravel into the future and back, but it would cause destruction of dark matter and matter. It would probably destroy the whole universe and possibly other ones too (depending if you believe Einsteins theory or not).
Yes, it's happening right now. Ooo, it just happened again!
We already are. If you want to skip bits, build yourself a really fast space-ship, and set off on a round trip somewhere into the cosmos at an appreciable fraction of the speed of light(c). You'll arrive back at Earth at a later time than you should've. It's called the Time Dilation Effect. However, for this to be noticeable over a short time period like a day (for yourself), you'd have to be travelling at 99.99% c.
I just did it and someone had already answered the question.
^ Like they said, you're already travelling through time at one second per second.
As for the time dilation effect, aside from travelling for a few years at a high speed and coming back to find you'd missed a few centuries, however, this form of time travel is highly impractical and doesn't work for missing a day or a few weeks.
It's also important to note that using this method means you're stuck in the future, as it doesn't work in reverse. You'd need a fully functioning time machine to get back.
If the g-force problem could be overcome then "missing a day or a week" could be done in a high-speed human centrifuge (like those used to train astronauts - just a lot faster). Time flow is dependant on speed and not velocity, so a few calculations on speed and length of time (outside of the system) the centrifuge is spun for and you could "miss" any length of time down to the second. Practically, this would be near to impossible to achieve due to the immense stresses on the system due to both g-forces and those introduced by the time dilation effect (effectively as the outer parts are travelling through time slower than the inner parts then the rotational speed along the centrifuge bar would be non linear causing the system to rip itself to pieces long before appreciable dilation occurs).
Wormholes are a plausible way to time travel ,but nobody has found out how to make one. But I ,a 13 year old boy, on the other have created an experiment that can make a wormhole that we can use to time travel. If you want to read the experiment plan follow this link...

Come back and ask that yesterday. - But seriously, nobody has yet developed the technology, and whether it's even possible is still open to debate. Different physicists have different theories.
Some believers in the paranormal think it's possible to have an out-of-body experience, and travel mentally to the past or future, while leaving one's body "parked" in the present. (Any possible danger to the body will draw the person instantly back to it.)
We all travel through time at a rate of one second per second
Yes, wait! It is 3042 right!?!
There is no known way to time travel at this time (except into the future at the normal rate of life). Many Science Fiction books talk about it, and some people claim to have done so, but so far, there is no conclusive proof. Some scientists and also some religions claim that there is really no such thing as time... it is just an invention we came up with to measure things, and so there is really no traveling in that way. Others think that it will eventually be possible, as we learn to understand more about the universe.
Only by using their memories to think about or remember past times.
because we are over 70% water
light can travel through a vacuum whereas sound cant
Science is more than just coming up with an idea and making it. They need to find a way it is possible to travel through time, then make it work, and go through a lot of testing. As soon as they find a way time travel is possible, they will make a time machine.
No, sounds cannot travel through a vacuum. This is because sound requires a medium to travel through because it requires the vibration of particles to travel and there need to be particles to vibrate for it to travel through.
Sound wave do not travel through vaccum as it need medium to travel.
They travel by rockets
No one has traveled through time before. In stories, people travel through time in a time machine.

you can'tAnswer:At present we all travel through time in the positive direction at the rate of 1 s.s-1. Time travel in any other direction is presently unattainable.
Photons do not travel through time. This is due to the fact that the faster you travel through space, the slower you travel through time. In other words, if an object is standing still, it is traveling at the speed of light through time, and since a photon travels at the speed of light through space, it is not traveling through time. -- Asker here, I hope no one minds me editing in to expand on the question/answer given. Surely the answer must be more complex. If a photon does not travel through time, then that could potentially violate/invalidate causality.
Time travel is only theoretically possible for certain particles of matter. Higgs something or other... In any case, (spoiler alert) humans are unable to time travel.
no
no
There is currently no know and confirmed way to travel in time.
The cast of Time Travel Through the Bible - 1995 includes: Jonathan Frakes as himself
Lets label your assumptions i) Time = Space, ii) I travel through time into space. Then by symmetry of equality we can deduce from i): Space = Time, which answers your question.
A time machine my dear!
