Welcome to Gaia! ::

I was searching around for some info to talk about on interdimensional issues and came across this - Interdimensional Photography.

I also found this, which is interesting but quite bizarre - Kryon - The Interdimensional Universe

I haven't read all of it yet because 90% of it is mind-boggling and it's just an overload on the brain - so I read bits and pieces. The trick is, sift through it until you find a piece that stands out and see if you can make a comment on it here.

Remember, despite this kind of thing already being something scientists are looking into and researching, we're still talking about fantasy as well here and how it's applied to various different works.

PLEASE, NO SCIENCE-FICTION UNLESS IT IS BEING COMPARED.

You don't have to read the entire lot to make comments Hypno. Even I haven't read the entire lot!

Pick chunks out if you want and comment on them. Whatever way feels most comfortable. I'm not asking anyone to read through absolutely everything unless they really want to.

My own personal theory is that, just like we're can only surmise that they're out there, they can only surmise that we're out here.

The sheer number of stars and planets in the universe makes it a statistical probability that there is other intelligent life out there, somewhere. But the difficulties of communicating and traveling across such distances (mainly being "the speed of light: it's not just a good idea, it's the law!") make finding out where, and indeed if, they are.

Take our own radio and television signals. It's a commonly-held misconception that they just keep going and after about three years or so, they hit Alpha-Centauri and are perfectly recognizable for what they are. The actuality of it is that due to the fact that our signals are spreading out over an exponentially larger area as their distance from Earth gets larger, they lose their power and completely fade into the Cosmic Microwave Background Radiation long about Neptune. We just don't generate a strong enough frequency modulated or amplitude modulated signal to make it as far as regular old EM radiation does. And this is the fastest-traveling thing that we can produce, as a civilization; radio signals travel at the speed of light.

So really, unless there's intelligent life between us and Neptune or a civilization is using a star to power their radio signal, SETI is pretty much wasting their time with a search for artificial radio signals. What their radio telescopes actually look for are wavelengths of EM radiation that suggest the presence of materials that would be produced artificially, such as high amounts of particulate carbon.

Now, in the case of physical travel, you will always be traveling slower than the speed of light, even if it's just a teeny-tiny little bit slower, because it takes infinite energy to accelerate to light speed. Plus, you have all the added complications of time-dilation and length-contraction to deal with when you travel at relativistic speeds, so any inter-stellar travel will be slower than that, even. For all we know, they're heading our way. It'll be a while before they get here. And even that is generous, considering that they had to happen to pick the right direction to go.

I'm firmly in the camp that reasons there is other intelligent life out there. If there isn't it's an awful waste of space. I just don't think they've ever been here. The distances involved are just too great.

I do look forward to the day the Voyager satellites find someone, though.

Heh... my physics degree is showing again... sweatdrop

Berz.

Man that is really long! and a confusing. I'll post later on my thoughts about, once i gather them, wink

Thanks for that info Berz! I am always fascinated to learn more about stuff like that even if I don't understand much of it, he-he. sweatdrop
Keep 'em coming!

But you know, I did hear about the fact that radio waves fade eventually but I didn't find out till a few weeks or months ago. Before that, I always thought they didn't fade.

On with the subject now, I think magical portals that could cut space and time and treat it like a piece of paper, could work when dealing with aliens visiting us or whatnot. You know?

The links in this were....

Right... I feel though I can't really add much to the topic just yet anyway. I'm not sure I've seen or heard enough about it to be able to start a good discussion or alike. Sorry... sweatdrop

Well, I'll see what I can do, but it is very SF in nature...

To answer some of your questions, here....

It doesn't open any dimensional rift, really. FTL travel (that's some common shorthand for "faster than light") just isn't possible, as far as we can see. The mathematics for calculating the energy you'd need does weird things like divide by zero (not actually divide by zero, but similar things that happen in calculus and linear algebra) and falls apart. Essentially, time and length both go to infinity meaning that it takes forever to get nowhere, or they go to single points meaning it takes no time to get everywhere. @_@

Aside from that, though, Star Trek's warp drive also had the problem of inertia; what happens to the people aboard those ships when they are suddenly accelerated to five and six times the speed of light? They should be squashed into gooey bits of atom jelly. When someone pointed that out to the writers, they invented "inertial dampeners" to band-aid the problem. But they never talk about what those may be. There's a million other such little and lethal problems with warp drive which leads most die-hard Star Trek fans to surmise that the show takes place in a universe where physics is different and this stuff is possible. But, basically, the answer to the last question is "no."

Black holes are an interesting conundrum, though. They're objects that are so massive that even the speed of light isn't fast enough to safely travel past it. Yet all their mass is collapsed to a single point at its center of gravity, meaning that anything that was in orbit around it to begin with is just fine, since orbits are concerned with centers of gravity. Anything whose orbit decays, though, is going in. It will be ripped apart into a single line of atoms on the way in and then... we don't know. Some people have surmised that this matter gets completely converted from potential to kinetic energy and is the source of the x-ray streams that are emitted perpendicular to the accretion disk. Others have surmised that the black hole's center of gravity actually becomes a point-sized hole into another dimension and the matter passes into that, becoming the source material for a big-bang elsewhere. But no one really knows, for sure.

Getting back to fantasy, though....

Magic portals between places in the same world can be a lot of fun to work with. I figure that each particular brand of magic will have to come up with its own explanation for how they work, though. In my world, it's completely an Astral Plain thing; you momentarily hop to the Astral Plain and that ferries you to the exit.

I wonder what would happen if a portal were set up to exit on the very spot you entered. Would you run into yourself and not be able to get through or would that be impossible because you haven't entered the portal yet? Hmm... I could have some fun with this...
