Portals heat up matter until it is particles, then the particles travel at almost the speed of light.
If you time travel to portals, you’ll see yourself comming out of a portal before you step into it!
Not if the time difference is a millisecond or less, it will seem instantaneous.
Ok, but seriously, would you make a rip time and space without making it suck up everything even light like a black hole or heat up particles and make them travel around at almost the speed of light?
What would aperture do, make a tiny wormhole and manipulate time and space or just heat and concentrate particles?
What would Valve do, calculate how you can be got out of an overlay 0.01 seconds before you touch it or just teleport a player from the overlays in a normal way?
Now what would Jesus do if he existed?
Oxidious’ idea makes no sense to me.
Neither does the idea of the superheated gas. I really don’t understand what you guys are getting at here.
Mine tries out quantum physical theories. I think Qxidious is talking about wormholes. We both are trying to find out how portals work, but it originally came from when I tried disapproving Oxidious’ theory. Also I was really talking about particles, the word gas just came up in my mind when I thought about what you get when you heat solid matter.
Do you have a better theory because you mean ours makes no sense?
none of you has any clue
Yeah I was reaching. Oh well, life goes on.
Yeah, I’m not sure exactly what you were going for, but here’s my 2 cents:
Time travel to the future does not violate any sort of laws of the universe. You’re doing it right now. You can get to “the future” faster by traveling at or near the speed of light for a period of time. That’s relativity, and that’s well understood. Half Life has already explored these sorts of things with Gordon’s stasis and the slow teleport at the end of Half Life 2. However, as we understand the universe, time travel to the past is impossible, except perhaps in situations where it wouldn’t be useful. (I’m referring to closed time-like curves, where you could theoretically go back in time, but still not violate causality, and multiverse traveling, where you can travel to another universe.)
Now I’m not saying Valve will or will not use time travel to the past in Episode 3, but what I am saying is that, so far, they have stayed pretty much within the realm of reasonable plausibility when it comes to the sci-fi elements of their games; they haven’t really shown anything that isn’t at least theoretically possible. I don’t see why they would change that now.
valve will not use time travel, except for the slow teleport in hl2
Yes. As a matter of fact, the portals in Portal are most similar to the real-life concept of a wormhole with a flat-faced throat, as opposed to the “Morris and Thorne” wormhole (which has a spherical one). In any case, the whole idea of a “portal gun” doesn’t make much sense, the actual space-time geometry would need to be manipulated. A large amount of “exotic” matter/energy would be required for the manipulation, and would continue to be required to keep the wormhole open.
You’re right, and that’s one thing I really like about the Half Life series.
Any reason why they wouldn’t, despite it becoming such a recurring theme?
Because time travels make retarded story lines?
Fixed that for you. 
Oh, that was probably the right word. thanks!
first, because marc laidlaw said so. Second, valve tends to stay away from too much recycling of story in their games. True time travel ie movement in the forth dimension can only happen in one direction due to paradox. So thats why i think there will be no going back in time to stop the black mesa incident or any other go back and fix it plots. Eli is dead, the earth is fucked and a nerd with a crowbar and an aptitude for killing is our only hope.
The 4th dimension is absolutely not time. It’s simply a spacial dimension.
Its confirmed Eli won’t be saved via time travel.
He will be re-animated MUHAHAHAHA
Just because the player won’t be going back in time, doesn’t mean the technology is not related to time travel. It could be that it could only (like you said) go forward through time, or that Gordon will simply not be able to revisit or alter known events & locations in the timeline, possibly doing so because of the paradox it created, or that Gordon will simply not be using the technology on the Borealis at all regardless of what it can do. (highly, highly, unlikely 
)
There are many theories of the possibilities of paradox-free time travel, made by people far more expertise in the field than yourself. (You will never crush my dreams of being in a monogamous time-travel gang-bang)
Are you referring to Einsteins interpretation of gravity as a geodesic?
I might be a blasphemer but I don’t believe in a thing called EP3
Half life episode 3 will not come out this year, I can garauntee that, because gabe newell said he was releasing portal 2 in a april and after that will come DOTA 2, which he said would also come at the end of 2011. Also gabe newell said they were working to get sdk to be easier to use and less of a hassel for both themselves and third parties, when they get done with that, expect episode 3.
