Time travel

[LAN_deRf_HA]

Am I the only one that doesn't count time dilation as time travel? A simple distortion just doesn't cut it. The only interesting bit about speed dilation effect would be to see if you could remove your mass and fling yourself against the speed limit, though I'd worry you'd just be sending yourself to the end of existence. Other than that just make a stasis pod. A lot more energy efficient.

Now that's science.. No telling why yet, but it just is..

So is a comprehensive study on whether the inclusion of pink flamingoes as yard ornaments are a natural result of genetic differences based on positron emmision scans of the subjects' brains.
Just saying.

Just because you can't travel faster than light doesn't mean you can't get somewhere before light does.. Look at the photon for example. It is always entangled in the opposite state as it's partner but it is never in the same location. You could have one of the entangled pair here and one on the other side of the universe but they will always react at the same "time"..
Now that's science.. No telling why yet, but it just is..

yes i know photon entangled always react in the same time, i just merely stated my theory, that when we start hit the speed of light the time will stop on us, and the whole journy become a blink of eye for us that why we can't travel faster than light even we assume that we have the technology to travel faster than light.

@kreji : so if there are no different in time them how do you explain the different time in our gps satelite clock to earth, isn't if there are no time different them why we must adjust it constanly?

There is no evidence to prove or disprove that going around the world as fast as superman will throw you into time travel. And since you cant prove it, its just a theory.

The "Grandfather Paradox" proves it can't be done which has been retorted with "Parrallel Universes." There are so many issues with Parrallel Universes theory; however, that it boggles the mind why it is even uttered anymore. For example, we know nature is not wasteful so why would nature constantly be dupicating itself in order to correct the Grandfather Paradox? And to explain that, they throw in Quantum Physics which basically state that, on the sub particle level, its pure madness and stuff happens randomly. Well, maybe if they stop making assumptions that they are seeing the whole picture, they wouldn't be making these sci-fi predictions that make absolutely no sense in the context of the universe.

Basically, time travel has created a giant mess of theories that try to explain how it is possible. As demonstrated by E=mc2, nature doesn't care for "giant messes." As such, I am confident going back in time is impossible and going forward in time is only possible through the limitations of general relativity (you can slow time relative to someone else not being so strongly affected by the space-time continuum).

We know that nature is not wasteful? Our highly limited perception of the world around us does not give us license to make that claim. And of course it's a giant mess of theories. That's science.

[micropage7]

you know i remember someone said that this world is paralel how many times we realize that we are here coz of 'plan' maybe like action to reaction if we are not here we should be somewhere in different time and different story
einstein said by using his theory of worm hole but so far its still a theory
and the time has 2 dimension which vertical and horizontal where the horizontal line marked with number lke 1hour 2 hour and so. the vertical line is unlimited which each one would have different experience of this
maybe i read philosoph too much

 

[theJesus]

And of course it's a giant mess of theories. That's science.

Pillar one: Science without results is just witchcraft. Pillar two: Get results or you’re fired. Pillar three: if you suspect a coworker of bein’ a witch, report them immediately. I cannot stress that enough. Witchcraft will not be tolerated.

 

[silkstone]

This is true as well, light does get bent around stars. This infact was used by Albert Einstein to prove his Theory of Relativity.

Well yea but you know what I mean...

Light is affected by the Sun, it just travels too fast to be pulled in. But the path of the light particle is slightly bent as it passes the Sun.



There won't be any "surrounding light", but yeah; the black hole will "suck in" any light that gets too close.

Again, gravity does not effect light, it does not pull light towards it, what gravity does do is bend space time, essentially making the path light takes it (relatively) curved. if gravity could effect light in such a way, it would imply that gravity could change the velocity of light, which is just not true.

 

[charles1]

Look we can speculate all day and night the truth of the matter is we dont know for sure. What we said was impossible has now been proven fact and possible.

also note that many Phd's have said that all known laws of physics fall apart inside a black hole and we have no knowledge of what truly happens inside a black hole other than it spits out hot gases and so on. Look with out getting all technical and busting math equations that half of us wont know the black hole can be and might be the pnadoras box to time travel or even greater treasures we can even fathom.

So here is a toast to the great unknown, If i were given the choice to father a child or travelk the universe forever I would choose travel the universe LOL.

So where do I sign up for Star Trek LOL

 

[GSquadron]

my theory is if you go around the world so fast that time doesn't pass you hit what i call absolute zero. then if you go faster you would collide with your self even mater or energy would do the same. this is a bearer even if you go in a strait line and go faster then absolute zero you would still hit that bearer.so time travel is impossible.

Your theory is not a theory, it is not constructed by proven postulates and what is worse yours is just a hypothesis. You need 3 proofs to make it a postulate and than a postulate is a hypothesis that none can turn it down. Also, I have proven that your theory is wrong: Faster than speed of light, dream of it. Sorry man, this thread is just a fool thinking. If you could travel, than someone from the future would come to earth. I also have proven that there is no time at all.

Faster than light speed travel is possible, but only by information

http://www.youtube.com/watch?v=okWNOnyCfMU i I am surprised no one has posted this yet! Shame on you all

On a more serious note, I think that for now Nasa should stop investing in heavy lift rockets that can transport us to the moon and Mars and instead start researching technology that can directly materialize us there(or at least most of our resources/equipment so that the shuttles can become smaller) by means of radio waves or light...

I'd be more interested in directly materializing at work or school or something. Damn gas prices

 

[qubit]

Well, Obviously time travel is possible and has in fact been done. They did this way back in 1985 in Back to the Future.

By information in what way? Because of light cones, information can travel at the speed of light but no faster, at least according to current science.

In more recent years, there is evidence that FordGT90Concept has borrowed W1zzard's time machine.

I'm refering to the electron spin pairs. I haven't read too much about it, but there was speculation that it could have applications in things like quantum computers.

yes, i don't know much either but it is confirmed that they can communicate across immense distances without being limited by the speed of light. it's been the big news the last few years.

Alright, makes more sense now.

 

[Kreij]

What does instantaneous communication theories/hypothesis based on quantum mechanics have to do with time travel?

Let's try to keep it on topic. I know ... it's hard for me too.

in the documentaries i have seen, they have theorized that the ability they have
to communicate instantaneously across space, could maybe be used to transmit
information and eventually, maybe - people.

i have not heard time travel theorized, but once you are talking about instantaneous travel
across the universe.... throwing in a bit of time travel doesn't sound SO far off

isn't light have mass too? So it can really affected by gravity, even light can't escape from blackhole. If light velocity didn't change then its really easy for light to escape from blackhole

 

[AphexDreamer]

Gravity effects light albeit indirectly.

Light AKA the Photo is a massless particle.

The reason why Gravity caues light to bend/become "Sucked In" by a black whole is cause light follow a path and gravity warps (Bends) that path. With a black whole, its gravity is so strong that it literally breaks a hole in the fabric of spacetime and Light falls in said hole.

Think of a bowling ball on a soft mattress with a marble rolled next to it. Thats like the Sun on the fabric of Spacetime with the Earth being the marble.

yeah I know that gravity can bend space and time, but there is no way light doesn't have mass, if it doesn't have mass then it can't be affected by gravity.

Btw there are recently a debate between scientist that there are no gravity at all, I will try to research it again to be more clear
