Will we ever invent teleportation?

Do you think it's possible?

I wonder about it occasionally.

Would you use it or would you be worried about being reassembled incorrectly, or inside a wall or something?

According to the theory its not possible. The physics of it prevent matter from being transmitted

I probably won't, it has taken my PA and I three days to work out how to get at the cartridges in my printer! I'll leave techy stuff to someone else and stay away from it I think for everyones' safety and sanity.

Teleportation of inanimate objects probably isn't very far away. I very much doubt that living matter could ever be transported in the same way

When 3D printers can print human tissue we can fax versions of ourselves anywhere!

At least that's how I do it. Only way to have five meets at the same time.

I'd love it and I can't see why it couldn't be possible...

But there are all sorts of philosophic arguments for and against this...

Like is it really "you" who has been assembled?

In theory, almost anything can be made to sound possible, but in practice its not, for one thing taking living matter apart at a cellular level would almost certainly result in death, and what you would have at the other end would be a copy, so therefore not the same person, so the ethical questions then come into play.

Time travel is also impossible, there is the theory that if you flew around the world faster than the speed of light, when you get back to your start point you can watch himself leave, but as mass accelerates to near the speed if light it becomes heavier and requires more push to continue to get it up to speed.

And I have no idea how I remembered all that from a brief history if time by Steven hawking, it must have sunk in some how lol

You can't go faster than the speed of light, it's the one constant in the universe...

But I have heard that "they" think it's maybe possible to bend time... So you could almost "see" into the past. It think it has something to do with string theory?

We know time slows down at mass, so manipulation is possible.

If you travel faster than the speed of light you can seee yourself leave but that doesnt mean you travelled through time.

Teleportation of photos has already been achieved; the first photon was destroyed and the new photon was created at a new location almost instanteneously using the principles of 'Quantum Entanglement'

So yes i for one believe in the world of science, anything is possible its just of matter of time give or take a few centuries before teleportation of organic tissues (Humans) becomes possible.

Unfortunately I think I picked it up from a copy of new scientist left on a plane, I don't really know about physics, I'm just an engineer, but I do know the speed of light is a constant, hence "C".

I think string theory is pretty easy to find though, but it's fucking mind bending!!

No and the impracticalities of millions of people using it would make it only for the super rich,I think.

You wouldn't be able to just beam yourself anywhere,that would be too dangerous with the population all wanting to do the same thing. There would have to be beam me up Spotty machines that took you from city to city,and you would have to book in advance.

What would be good is a unit in your house where you could have your shopping beamed to. I'd advocate that but that would do delivery drivers out of a job. They would have to train as Spotty machine repairers or builders.

But if you leave point a, and arrive back at point a before you have left point a, then you are at point a in the past, seeing the past, therefore time travel has at that point been achieved, thats the theory anyway.

You could theoretically transmit the information to copy an object at the receiving end, as long as you had the ability and materials ( ie the right atoms, subatomic particles,) to put it together, and the time and computing power to make that copy. But it would probably take the most powerful computer we have today, several hundred years just to do the calculations and produce the data to make an identical copy of something like a tennis ball.

But you can't possibly conceive how you would copy the personality of someone, their memories, their knowledge, emotions.

Unlikely that you can transmit " actual matter" . But if you could, you would have to break it down, beyond atomic level, to sub-atomic particles .

To do that, just with the tennis ball, would need the energy of several megaton nuclear bombs, just to break the atomic bonding energy.

So it's not entirely practical , sadly...

"According to the theory its not possible. The physics of it prevent matter from being transmitted"

You can turn matter to energy and transmit that.

But the amount of energy from one human being being turned into energy would be thousands of megatons equivalent. E=mc^2

Makeing them insnaly dangerous and the bean would lose energy on the travel (and be a freaking death ray!)

If they transmited just information it would really just be a cloning machine though

He had that many theories all with their own special exceptions. General Relativity deals with extremes of gravity such as black holes but I think that has loads of exceptions and special 'rules'.

Inthinknthe General gist is that the speed of light is constant unless it isn't!

Black holes can't change the "speed of light", they can prevent light passing through them and they alter space-time through their mass...

Plus Einstines theories have been way surpassed and he had no idea how to prove any, that was left to people who "do".

I read a story about teleportation of humans. The basic storyline was that when the new person was created, the old one was incinerated. Sadly there was a fault and both copies were alive at the same time, in different places. It brought up lots of legal and moral questions about being human and maintaining identity.

Dont think I have seen that. Is it the one where he goes home and his double is already there?

My story never got that far. The 'original' was contained for incineration and the 'copy' was fighting him legally to prove which one had the right to live.

Not exactly. IIRC, They conducted an experiment where a molecule or atom on one side a river was moved, which resulted in a similar atom/molecule on the other side moving in a complimentary fashion- with no other influence.

This is essentially the essence of one theory of teleportation, but far from being actual teleportation.

Impossible.... A "signal" of any kind will always be considerably slower than the speed of light!

A "signal" must travel through some other medium, even if light was used (a laser) the medium it travels in would slow it down!

The warp bubble theory allows for the possibility. If anyone can ever create a stable warp bubble.

Not sure I'd like teleportation. Iv seen the fly (original one is scarier)

"They've already teleported atoms. Well, one, it took two years!

As for the speed of light being constant, it isn't. Gravity has an effect on the speed of light.

Mass has an effect, but it's still the exact same speed.

Einstein's theory of General Relativity hints otherwise, but again, it's all relative..

And yet he used it as a constant in special relativity and our understanding of the universe, electricity, space time, reactance and a whole host of equations would be useless without it...

"

Just to point out its not a constant as in unchanging .

The speed of light in a vacuum is constant in that it never increases

You can slow it down with somwthing as simple as a pane of glass (using cesium at near absolute zero i think weve gotten light down to below walking pace)

But that is the speed of light in a vacuum unaffected any anything else that is constant any light of any power of any wavelength in that same situation will travel the same

"Do you think it's possible?

I wonder about it occasionally.

Would you use it or would you be worried about being reassembled incorrectly, or inside a wall or something?

OP...

I believe that teleportation has already been invented. It was done a few years ago.

Not exactly. IIRC, They conducted an experiment where a molecule or atom on one side a river was moved, which resulted in a similar atom/molecule on the other side moving in a complimentary fashion- with no other influence.

This is essentially the essence of one theory of teleportation, but far from being actual teleportation.

As for teleportation/ time travel/ faster than light travel being impossible- that's making the assumption that we understand all the laws of physics in the universe........we don't understand all the laws of physics on our own planet

I cant remember which physical lab did it but I seem to remember that an atom has been transported from one place to another, but will accept that I am misremembering...

However as far as faster than light travel is concerned I believe that CERN has already managed to send a signal from CERN to Italy and back."

No that was a false positive it was caused by an optical fiber being lose in the timing circuit.

The neutrinos did not travel faster than light

He had that many theories all with their own special exceptions. General Relativity deals with extremes of gravity such as black holes but I think that has loads of exceptions and special 'rules'.

Inthinknthe General gist is that the speed of light is constant unless it isn't!

Black holes can't change the "speed of light", they can prevent light passing through them and they alter space-time through their mass...

Plus Einstines theories have been way surpassed and he had no idea how to prove any, that was left to people who "do"."

Yes they can slow it.

For instance high energy particles in a water moderated nuclear reactor travel faster than the speed of light in water.

This is the cause of cherenkov radiation (that beautiful blue glow) and it occurs whenever aomethign travels faster than light in thag medium.

Can be thought of as a sonic boom for light.

Its very beautiful

Thanks did not catch the announcement that the original result was wrong. Did they (politician style) hide it on page 457 of 458 page report, or slip it out at the same time as something big was happening?

"

And that is fast compared to the time it takes a photon to get from the centre of the sun to the surface at between 10 and 170 thousand years (thats somewhere between a mile a week and a mile year! LoL.

However as I understand E=MC2 it is not that something cannot travel faster than light (in a vacuum) it is that nothing can be accelerated up to and past the speed of light. What is being proposed and researched is ways of stepping round the light-speed barrier...

No there was a major race to reproduce the result they even started equiping a new lab in japan to reproduce the experiment when it was found out.

One thing about science is if you do something new the whole comunity jumps up to see if they can do it too

I read that a single photon takes anything from three to six million years to get to the surface.

it bangs into everything on the way out and gets absorbed and remitted.

Starts out as an xray finishes as visible light.

So a fair amount of energy lost

Then its just 8 quick miniutes to earth.

Can't be arsed to read the whole thread (it's late) but I thought some scientists have already teleported light several years ago?

You should YouTube 'spooky action at a distance' with this theory it seems very possible, but whether or not the original you dies in the process is another question according to how that would work ... love this stuff

"In theory, almost anything can be made to sound possible, but in practice its not, for one thing taking living matter apart at a cellular level would almost certainly result in death, and what you would have at the other end would be a copy, so therefore not the same person, so the ethical questions then come into play.

Time travel is also impossible, there is the theory that if you flew around the world faster than the speed of light, when you get back to your start point you can watch himself leave, but as mass accelerates to near the speed if light it becomes heavier and requires more push to continue to get it up to speed.

And I have no idea how I remembered all that from a brief history if time by Steven hawking, it must have sunk in some how lol

You can't go faster than the speed of light, it's the one constant in the universe...

But I have heard that "they" think it's maybe possible to bend time... So you could almost "see" into the past. It think it has something to do with string theory?

We know time slows down at mass, so manipulation is possible.

...but isn't the current thinking that although the speed of light IS the current absolute maximum speed anything can travel, scientists are theorising that millions (possibly billions, excuse my poor memory, it's been a while since I read up on it) of years ago the absolute maximum speed may have been different, furthermore, in an ever changing universe (or perhaps even multiverse) that, absolute maximum speed could change again....

Mind. Blown. "

And there'll be some space copper with a speed gun just waiting for you to go over the speed of light and .... Well you know!!
