Timetravel

I'm sorry, that was indeed a bit vague.
This is what I meant: it sucks in the gas. The gas then needs to go onto the orb shaped ball of matter that is the black hole, right? -since there is no such thing as a hole, just extremely dense matter- The amount of gas that is being pulled towards the black hole is so huge, that it is being pushed away from it again. This happens at the poles of the orb. It creates some sort of a vortex, like in water, but if there goes to much stuff into a vortex at once, the matter is pushed away again.

 

...I'm not entirely sure what you're talking about.

The pull of a black hole is so strong, literally nothing can escape, not even light, not for the slightest split second. Gasses, anything with any kind of mass really, would be pulled in, impossible to escape. The pull of a black hole, as far as I recall, is strong enough to super-compact near any substance if needs be.

If you're talking about a quasar, that's completely different animal. Those are redshifted starts with a huge EM signature, but they're basically the opposite of a black hole. They don't spew material, just RF interference. They're formed from a black hole, yes, but if I recall, they're not a black hole of themselves, just a signature of one.

 

That's it. Discovery officially sucks now. I don't know where you learned all that, but I watch discovery. A lot. Since they started broadcasting mythbusters and brainic, the quility of their documentaries has drastically decreased.

The stuff I said here was all taken from stuff they broadcasted. I seriously hate it that they started broadcasting those mainstream documentaries. They leave out every important thing and simplify the rest to the point that the information become incorrect. Any suggestions for a better source? A website or something? I really start to get pissed of that I am always wrong when using stuff from discovery...

 

Eh, it's possible the translation into Dutch looses a bit of accuracy.


Also:


Do you seek knowledge of time travel?

 

Crap. I really was about to post that.

I seriously lost like, almost my entire army when listening to that for the first time. I wanted to know how it ended. Arbiters are kewl.

About the documentaries: the translations are horrible. I try to just listen to the voices of those people, but not reading text right in front of you is really hard. And those illiterate morons always put subtitles over the text on the screen. You never see the names and titles of those people, or more important stuff.

 

well, I dont think we can time-travel, but perhaps slow time a bit for a person...

 

Alternative energy sources are, I think,
and there is that direction which will deduce the world from crisis.
The epoch of oil and gas monopolies will end.

 

maybe he's talking about the accretion disk? when something falls into a black hole, something of equal momentum is shot out (probably high-energy EM waves). this is due to the conservation of momentum. once something is "inside" a black hole, its momentum is "lost" to the universe. something of equal momentum has to replace it. this doesn't actually come from the black hole, but just some odd thing that happens at the event horizon.

i'm no astrophysicist, so don't quote me on this.

 

Time travel races too many questions........ perhaps teleportation will come 1st before time travel is discovered.

 

we already have teleportation... sort of. scientists have managed to "teleport" a single atom.

 

actually they are up to a few molecules now

 

Teleportation today (and probably for some time to come) is limited to a) information only (no actual matter) b) speed of light.
Definetly not something that allows you to 'beam' to a different location or travel back through time but it does open up new ways how to improve information transfer, computers and quantum computers.

 

technically teleportation IS the transfer of information only, if you think about it. what's the point of teleportation if you're just going to transport matter at the speed of light, and then reassemble it at the other end? might as well put it in a box and move it the traditional way.

teleportation as we have it right now (several atoms or simple molecules) is really just sending information across a distance, and using that information to create an indistinguishable copy at the other end. and that's the way it SHOULD be.

 

yeah, i am a bit concerned about that though


see, if they teleported me, from the perspective of my relatives, i'd live on. From the perspective of my copy, i'd live on. But from my own perspective i seize to be.

cant we just bend the space-time continuum untill i am at the spot where i want to be?

 

If we develop means of teletransporting people using information I'm SO not using it. Ever.

That's not happening anytime soon though. As it is I don't think we would be able to store that much information

 

Well in order to teleport objects of value, such as equipment or living matter (namely people) you would really need a machine that could assemble extremely complex objects (such as human body, including brain with memories, etc.) in a feasable amount of time (think seconds, minutes, hours) and you wouldnt achieve a movement of an object or person, you would in fact copy it. Which is actually cooler than teleportation but its not star trek. Anyways with the current take on teleportation the only part where the actual teleportation comes in is when you transfer the information about the object and it is still LIMITED to c. Sure you can transfer much larger bulks of data which you probably would need in the future communication, but thats about it.

So what did I achieve in writing this paragraph? Nothing. The fact still is that teleportation still boils down to speeding up the porn downloading process.

 

what happens when i time travel paradox occurs?

like you went through time, then you went back to stop yourself from going through time, but then if you stopped yourself from going in the first place, then you shouldn't be back stopping yourself from going in the first place....and so on, and so forth

 

You just explained what would happen yourself.

 

The fact that it's moving at the speed of light, which is impossible through 'box transport'.

 

it's impossible either way. moving matter at the speed of light, even one atom at a time, takes infinite energy. getting near the speed of light takes a crapload of energy. you remember all that crazy talk about the LHC destroying the earth and crap? yeah, that amount of energy is used to accelerate only a few atoms to 99.999999% the speed of light. thus, why bother breaking it down/reassemble if it's going to take so much energy anyways?

moving information at the speed of light takes almost no energy by comparison. we do it every day, with radios and cellphones and lasers. that's the real benefit of teleportation. you just analyze the matter, send information about the matter, and then build a new one at the other end.
