Large Hadron Collider Could Be World's First Time Machine

[Retodon8]

it will only be able to send messages to the future if this works and in the future where they receive the message they will already know if it works. unless i totally misunderstood the article. . .

The latter.
Sending a message to the future is what normally happens, even at sub-light speeds.

Yes, it's all been said, and debunked before.

Really?
You'd think the scientific world would have heard about it.
I doubt anyone who could debunk that would keep silent about it.

There is already a "quantum entanglement" type system that theoretically could send messages across light years instantly. But it is far out of the reach to use that to send any type of real message across distances it just means that a particle split apart will share the same state of its twined particle when you change the others state. Pretty old news to since scientists knew about it since the 70s or 80s, but proabyl decades if not centuries form being able to use it for anything useful.

This news will probably take 100s if not 1000s or tens or hundreds of thousands of collisions to just get the particle to appear and then captured on the sensors that monitor those collisions, assuming that the particle in question does exist.

String theory predicts all sorts of odd and somewhat nonsensical particles with its multidimensional models. What we find out in these super colliders could go a long way to confirming string theory and weeding out what models of string are correct or not.

Even if future us could harness something like this to create and send back actual messages it would be like sending blackberry messages to a caveman that does not have a mobile device to receive them. And probably be a long long time or never most likely that we would have the tech to monitor these super exotic particles to any reliable degree at all nevermind decipher any hidden codes that might be stored within.

So do not be holding your breath for them future lottery numbers or the next sports bracket via your future self even if they could send it you would never know it.

Sounds pretty cool and all but we're still a long time away from this.
How much bigger would this Hardon Collider have to be than the already existing one or are thay talking about that one?

 

[Ponce Master-General]

They say that it's possible because it avoids any big paradoxes, but time travel is a paradox in of itself. For example: if someone was to send a message to the past, then we would already have known it, because, by Back to the Future law, only the time traveler is aware of the changes in time that he made. But if there isn't a time traveler, there's nobody that's aware of the change, and it's like it never happened.

Who knows, maybe next week, they'll send a message to the past that reveals the LHC as a potential time machine, and that's how we discover that it is.

Everyone who's saying that we haven't received any messages yet is a fool. We cannot have messages yet as we have not been looking for them. Until we create a detector/sending system, we won't get any messages. It's exactly the same with time travel itself.

 

[Brandon237]

Wait....

Does this mean it failed?
Because this thing is going to be turned on in the future, ergo we're currently in it's past and we haven't had any messages yet.

The "messages" would be sent in Higgs singlet particles, which, I get the feeling, our normal radio equipment can't detect. We will only know if it failed once we have equipment monitoring for signals made up of these particles.

Now, I'm no physicist, so all you PHDs out there correct me if I'm wrong, but I've been told that it will only ever be possible to travel FORWARD in time.

Discuss

I believe that if it worked, it would already have happened. Either that or tear the universe.

Part of me doesn't like the sound of this. Personally I'd rather leave time travel to The Doctor.

At least we're not gonna send anyone through it to mess up history.

sending anything can get the same result ....
if i send a message to say 1937 and tell them .. kill this Hitler fellow , hes a douche in the making. the entire earth will change.

time travel is just a big ass paradox , also if this is a potential time machine in Theory the fact that we have no messages from the future at this very moment proves we dont invent a time machine ever...

not necessarily. perhaps it is just decided that no messages shall be sent backwards in time for fear of disrupting the chain of events that leads to how things are currently.

 

[theheroofaction]

Okay, if time travel were possible then people would already be receiving winning lottery numbers.

 

[Sixcess]

I don't see why someone from the future would use time travel to come back and tell us that we will get time travel. I mean, if I had access to something that awesome I'd want to ensure that only I had that power, and I'm betting any future inventor/government/sentient AI bent on the destruction of humanity would think the same way.

Going on that reasoning the people we have to watch are those who are most adamantly denying that time travel is possible. Well, them and anyone who carelessly starts a thread entitled "I just finished Mass Effect 3 [Spoilers]"

 

[Venereus]

This completely fucks up Rebecca Black's song!

 

[Jandau]

My guess: every message we send back will not result in any changes to our timeline, but will simply cause an alternate timeline where the message is recieved.

 

[Daverson]

The issue is however, once we do get our foot in door as it were, whether we can go through isn't the pressing concern, the pressing concern is whether those on the other side can.

Think about it, if you had the opportunity to move a significant chunk of our civilization back in time to 1011CE, you'd definitely consider it - a lot of raw materials, such as oil, weren't exploited like they are today. There wouldn't be so much pollution. Never mind the fact you could use modern technology ("indistinguishable from magic") to establish yourselves as kings - perhaps even gods - in the eyes of our relatively primitive ancestors.

When I read the title I checked the date....not April Fool's.

So time travel eh? Let's not fuggitup.

I'm with you on this. If this were possible, then someone would have found a message of sorts describing and confirming this. Unless there are multiple time streams. In which case, even if we could send a message to the future and/or the past, we clearly can't change anything and therefore the act of doing it is ultimately useless, unless you spend the time and money to do it for the sake of doing it.

This is the thing best left in pages of Science Fiction novels and comic books as far as practical use is concerned.

 

[MelasZepheos_v1legacy]

If we haven't already received a message from the past saying 'hey, we found the particle but you still need to look for it or else there'll be a paradox' then I'm calling no on this one.

Seriously, the first thing I'd do with a time machine is leave myself the notes for how to build a time machine in the past, creating a stable time loop.

 

[Vanbael]

Hmm, interesting. Now can we work on Mass Effect field generators?

[thethingthatlurks]

Uhm, no. While a particle that travels backwards in time can certainly exist, it can by its very definition never be detected. Sorry guys, that's a major physics fail.
