It might be thought that special relativity provides a short negative answer to this question. In actual fact there are many trivial ways in which things can be going faster than light (FTL) in a sense, and there may be other more genuine possibilities. On the other hand there are also good reasons to believe that real FTL travel and communication will always be unachievable. It is sometimes objected that "they said no-one would ever go faster than sound and they were wrong. Now they say no-one will ever go faster than light. . ." Actually it is probably not true that anybody said it was impossible to go faster than sound. It was known that rifle bullets go faster than sound long before an aircraft did. The truth is that some engineers said that controlled flight at faster than sound might be impossible, and they were wrong about that. FTL is a very different matter. It was inevitable that someone would one day succeed in flying faster than sound once technology got round the problems. It is not inevitable that one day technology will enable us to go faster than light. Relativity has a lot to say about it. If FTL travel or FTL communication were possible then causality would probably be violated and some very strange conclusions would follow.

in a sense NASA all ready has built a time machine its called the space shuttle. Yes when the astronaughts return to eart the time pieces on the shuttle are behind earths time by a few microseconds, sure its npt a major leap but time travel none the less. Also if you could go back in time over great spans off time then everything at that moment would have to be stored somewhere.

You're going to need
some kite string,
some old newspapers.
A wind -up type alarm clock.
1 package of elbow macaroni.
A small bottle of glue
some glitter (Large bottle)
3000 pounds of weapons grade plutonium
A strong wooden chair
an old motor from an electric fan.
An Off/On switch or an old light switch will do.
Next get your mom and dads permission to be gone for a little while.
Now for the assembly instructions

Here's what you'll need.
1. Corona blast generator.
2. Thermonuclear fusion reactor.
3. One small rotating black hole.
4. Mickey Mouse watch or equivalent.
5. Tin foil hat. (May substitute aluminum if tin not available.)
6. Alien spacecraft capable of lightspeed or better.
7. One pair of quantum dice.
8. The complete works of H.G. Wells.
9. Inverse mux manifold.
10. Quantum dot gates in the following amounts:
(a) AND gates: 6.02 x 10^23
(b) OR gates: 2.
(c) NAND gates: 13.7 billion
(d) XOR gates: about a google.
(e) BILL gates: zero.
When you have all that, write to me and I'll come over to your house and show you how it all goes together.

"The easy button"?
or perhaps, the circle laser light thingy. Personally, I like astral projection. It's much cheaper, and you don't have to concern yourself with the physical limitations of light. The speed of light is the physical barrier between the physical and supernatural. Learn to travel in the supernatural, then you can control the physical better.

Probably a better chance than traveling through time is sending a message through time. You are really better off just sending information back in time.
Also, the passage of time depends on what city you live in. If you live in Colorado, you are gaining about a minute every year over someone living in Israel due to differences in speed as you travel through space.

You don't need any resources at all. You're already traveling through time at a rate of 1 second per second.
Congratulations, time traveler!

Scientists in Sweden successfully "transported" a single photon (particle of light) and they calculated that a time machine would need the energy equivalent to our Sun.

before thinking about the resources needed, you first need to think and compute about how are you going to be faster than the speed of light.... because that's the main reason why people can't built time machine because they can't go faster than the speed of light, and that's what you need,or else you'll not survive in your time machine and you'll be thrown to the black hole...

do you think i will write it for you and let you build a time machime which i should have build ?
any way i will write it for you. you need 1 mom and 1 dad! then let them involved in a fight. thats it. time machine is ready.
