High School Relativity & Computer Calculations: Speed Up 300x?

[danielhaish]

TL;DR

In higher speed the time is slower so the computer can make the calculation that depends on time count faster

there is many analog dividing machine that base on time counting . so does this machines work faster on height speed system such as
Particle Accelerator it may help in decryption of public encryption and other coculation .
It looked at relative calculator and in the speed that close to the speed of light you can get that it will be 300 time faster

 

[Drakkith]

On the contrary, the machines would be slower the faster they go relative to you and I here on Earth's surface. At 0.866c a computer would experience about 1 second of time for every 2 seconds here on Earth, roughly half of 'normal'. The clockrate of a modern processor of, say, 4 ghz, would only be 2 ghz from our point of view.

Remember that while the computer itself would also see our own clocks here on Earth ticking at a slower speed, the information has to be sent to us in our own reference frame. We aren't the ones who would go to the computer's reference frame.

 

[danielhaish]

Yesh bu the information may be send after the all cuclation

Doesn't matter. What you are proposing is a variant on the "twin paradox" scenario with the computer (and possibly its communication links) being the traveling twin. The computer has less time to perform its calculations than one at rest on Earth would have.

Lats say you have really hard question in math and solving it takes 20hours but the answer of the question is only 1 digit number so you can sned it faster thrn the time it take to solve it it not about information it about actions for one direction function

You apparently are not understanding the answer Drakkith gave you. Sending the answer to the math problem would not occur until LONG after the computation was finished on Earth. You have time dilation backwards. Please study it before posting on this again.

It doesn't matter. As viewed from Earth, the moving computer runs slowly. It would take (for example) two hours by Earth clocks to do a computation the computer (by its own clock) needs one hour to do, plus the transmission time. You could just use a computer on Earth and get the answer in an hour.

 

[danielhaish]

How do I know that the transmission time is the same time as solving the problem

 

[Ibix]

It isn't. Why would it be? The problem with your idea is that it takes longer for the traveling computer to do the calculation than one on Earth. The transmission time just adds more time to that.

 

[danielhaish]

So I need the other computer to move slower then Earth and then the time will work faster on it?

No. This isn't about who is moving faster - there is no such thing in any absolute sense. It's about who is not moving inertially (at least in a simplistic scenario like this one). To get the Earth to experience less elapsed time you need the Earth to follow a non-inertial path. That means you need to accelerate the Earth to near light speed, stop it, turn it around, and come back to the computer. That isn't practical.

 

[danielhaish]

Now i got it

 

[David Lewis]

Possibly if the computer is in outer space, and you're at the center of a large, dense planet, you could obtain the answer more quickly.

 

[bland]

Just build a slower computer and voila! your computer is now faster relative to that slower computer.

 

[klotza]

This would work if you kept the computer in an inertial frame and then sent the Earth off on an out-and-back relativistic journey. Do not recommend.

Do you really need the out-and-back leg of the journey, you don't need physical access to the computer? You could send the answer back at near light speed.

Now let me answer my own question. No you can't send the answer "back" you can only send the answer forward in time. Thus you need to wait for the end of the computation to transmit the answer. Whereas, if you send the Earth on a relativistic journey you could time your journey such that you return to the stationary computer in time the read the answer. So out-and-back is required.

I put together a space time diagram to demonstrate.
