Wouldn't it be highly dependent on the width of the boundary? The smaller the width the more drastic the curvature, and, thus, the greater the tidal force? We don't feel tidal force on (or near) Earth because the curvature is extremely slight (10% between the surface and the orbit of ISS)...

Yes, "gradient of the gravitational potential" sounds like a reasonable term. A hollow sphere is a reasonable approximation of what I want it to look like inside of the other hull, though, of course, I would like it to be a relatively manageable size. A planetary mass spacecraft is not...

Also, since there is a time aspect to the curvature how would straddling two reference frames (curved and flat spacetime) affect your body?

As far as I can see that entry doesn't deal with the transition between curved spacetime outside and the flat spacetime inside. I'm assuming there would be some kind of tidal forces felt there, but how would they manifest? What would it feel like to climb through it? Would the effects be the...

That's a good point, but shouldn't there be tidal forces within the boundary? Presumably the transition between curved spacetime outside the shell and flat spacetime inside would be on the same order as the width of the shell (give or take a little due to the existence of the hole).

I'm writing a sci-fi story and I'd like to make it, at the very least, scientifically plausible (in the way that alcubirre warp drives are possible assuming we could get our hands on something with negative mass which, as far as we know, doesn't exist). The basic assumption for these questions...

Voltage is a measurement of the difference in electrical potential between two points in a circuit. The concept of a "ground" can be confusing, many people will say "ground has zero volts." This doesn't make much sense as voltage must be compared between two things. You can say something is X...

As we get to larger and larger nuclei the periodic properties break down due to relativistic effects. I assume that at some point a nucleus would be so dense as to collapse into a tiny black hole (which would likely evaporate quickly). So that's probably an upper limit. Though, since gravity is...

Hmm, on second thought, I suppose it might be possible to achieve synesthesia through meditation since, as I understand it, an LSD trip can have similar effects. However a study would need to be done to figure out if it's the same effect and, if it is, whether the same part of the brain is at work.

I'm not sure this would be classified as synesthesia, while dreaming synesthetic crosstalk is normal. In fact, it's your brain that's generating the experience so not only is synesthetic experiences during dreaming possible, it might even be extremely common. While dreaming you know things...

True synesthesia, as I understand it isn't something you can learn or train yourself to do. It's not something you can achieve through meditation. It's unregulated (or misregulated) crosstalk between the hemispheres. And it's not something that can go away when you're done meditating, it's a...

I call hogwash. The only way an EEG can show no brain activity is if you're brain dead, you don't have the EEG hooked up correctly, you're faking the EEG reading, or you're only showing part of the EEG. And of course, the wikipedia article says: If that's true he really has no idea what...

Ooh, I don't know if I'd say vision is primary unless you're talking about what we notice consciously. Smell has a much more direct connection with memories (sound too, but less so). The difference is that it smell is a little more subconscious than sight.

rhody, zoobyshoe: I seem to recall that it was taste and sight. In other words letters, numbers, shapes, and other symbols can not only have color but a flavor too. Then again, maybe I was thinking of quarks...

So, does it screw you up or make you think harder if I do this: A What was wrong about what I've been saying? (keep in mind that your synesthesia is going to be different than someone else's. Difficulties you come across may be simple for others and things that are simple for others may be...
