Is Time Travel and FTL Intertwined?

If one were to achieve faster than light speeds, would time travel be an automatic bonus? And if so, how would you sort the two out, or apply one or the other.

And how did this get posted on this forum? Please move this for me mods, thanks.

Time dilation is real, but the thing is, you can never go back.

Prove time dilation is real. That concept comes from Einstein's Theory of Relativity . You did know he threw that into his equation only after 4(?) years of being "stalled" . Had to pull something out his rear.
It was tested at one point by having 2 atomic clocks. One was stationary on earth and the other on a high-flying aircraft .
The time came up different. However , at the time , no one thought of accounting for the higher electro-magnetic radiation or the effect of gravity.

Can't really see it as a bonus...

the rest of "time" ages while said traveler does not in theory

If you have a sat nav, there's your proof that time dilation is real.

They have to a configure all gps sattillites by like X billionths of a second to make them work.

The first gps tests were all off by 6 miles. Then they figured out that time moves at an ever so slightly different rate without the mass of the earth slowing time down.

It is a known testable phenomenon.

Using Einstein's theories, it's been determined that to travel faster than light would take an infinite amount of energy. In other words it's not possible.

Einstein's theories could be wrong of course

So , atomic clocks couldnt prove it but yet satellites can ? Wouldnt that be a worse test than the ones they ran in the 70s ?

You did realize the meaning of the above ? Your words , not mine. So , how did the speed of light play into this? I see only how gravity can effect any wave or particle.That is well known . Or , do you have something else ?

a reply to: standingwave

Forwards? yes. Backwards? no.

Time is relative to motion-the faster you go, the slower time passes and astronauts GPS satellites are a fraction of a second younger then we are. TFL travel would require a miraculous breakthrough in physics as even the smallest proposed space probes could only make twenty percent of the speed of light.

To reiterate, FTL travel would be possible IF we could break the laws that are already set in stone.

You can change the metrics of the vacuum and alter the value of the speed of light to that much higher than normal. So you are trchnically travelling faster than 300 million kilometers a second. But youll still be subluminal to that altered piece of the vacuum although superluminal to the restof the universe.

It wouldnt alter time (other than the toying with the guage of the poynting vectors of the EM ZPF) so no time travel in this scenerio.

a reply to: Thecakeisalie

Looks like those laws arent set in stone yet. At least major military contractors are exploring where mainstream physics got off track 100 years ago. They are comibg to different conclusions about altering time space metrics than relativity and einstein. You just need to know which guys to read up on and be surprised whos paying for the research.

Which would mean , if you believe in time dilation , that any speed greater than the speed of light would mean time would flow backwards relative to the "ship"
And dont forget , Einstein's General Theory of Relativity states the speed of light is an absolute. There can be no speeds greater.

a reply to: BASSPLYR
How so ? And why just military contractors ? Please elaborate.

a reply to: Gothmog

Cause they have to come up with solutions to strategic and tactical problems or people die so they tend to do the most creative and out of the box thinking and are willing to look at alternative math and equations even if they ultimately go in the face of conventionally accepted wisdom.

Plus the trillions of dollars invested to develop any kind of advantage.

Is Time Travel and FTL Intertwined?

To answer the question ,no. In the 70s some researchers found a particle , a certain type of quark . Major breakthrough as this particle decayed backwards. As it decayed backwards , this particle was proclaimed to be able to travel at greater than light speed. Reinforcing time dilation , but putting an end to the speed of light barrier.

However , in the 80s researchers found this was just the normal decay process and nothing earth shattering.

One of the 21st Century's(meaning current and not 20th Century and back science fiction) theories on time travel has to do with first a creation of a self-sustaining black hole. Then you have to spin up that bugger to light speed and maybe create a wormhole.If it would be possible to exist after entering this said black hole and passing through the wormhole , it may be possible to travel in time. However , which universe in the multiverse's time period you would enter is anyone's guess.

a reply to: jamespond

Not wrong just missed a point here and there. Assuming you cannot decrease the mass that is being accelerated leads you straight to his conclusions. But IF you could that would lead you to the stars.

a reply to: Gothmog

We already have the means to travel among the stars but these technologies are locked up in black projects and it would take an act of God to ever get them out to benefit humanity.

There are several more also attributed to him. Try the TALK: Ben Rich: Wikipedia entry for several more.

And that is just Lockheed. There are also Boeing, BAE, Northrup, etc... so yeah, military contractors.

The same effect holds true as you accelerate, even on earth. It just scales and is such a minuscule change it is unnoticeable.


Time doesn't "warp" the second you hit light speed, it is a gradual thing.

When it is every single sattilite that has ever been launched, then yes....

It's called science, repeatable verifiable experimentation...


Can I ask your religious affiliation?

This screams of creationism...
