LH:"On what basis would you assume that it is impossible for aliens from other dimensions or beings from other planets to visit us? Are other dimensions impossible? How do you know? Are aliens on other planets impossible?"

Very much to the point, Little Hawk.

According to Michio Kaku, a solidly grounded theoretical physicist (several books such as Parallel Worlds and Physics of the Impossible), it may very well be that there are "multiverses," not just the universe that we know, (about which, as one scientist put in, "we know only about 4% of what we wish we knew."). Multiverses connected like a bunch of grapes, and to a degree in contact (but separated by "branes" or membranes) with each other. And as to the matter of multiple dimensions, current estimate is that there are eleven. Three we know about directly (length, width, depth) and the fourth we have a strong sense of (time).

Michio Kaku and other physicists say that the math exists to prove this.

And there are a number of universities and colleges (such as the nearby University of Washington) and other institutions that have astrobiology departments (also called "exobiology") dedicated to studying the possibility of life on other planets. And these folks are not kooks, they are serious, dedicated scientists in a number of disciplines.

There is also the current search for terrestrial planets orbiting other stars (over a hundred planets located so far, several of which are "terrestrial" or "Goldilocks planets"—not to hot, not too cold, but just right, suitable for life as we know it.)

And there is the SETI project which has been going for some decades now.

And how about the Drake Equation? If you don't know what it is, it might be therapeutic to look it up and learn about it.

Now—my position on this is essentially "agnostic." I don't know if there is intelligent life on other planets. Nor, for that matter, does anyone here! Nor do any of us know that there is not!

Dr. Kaku came up with an interesting speculation. Perhaps what some people have perceived as "paranormal" came as the result of "leakage" from other dimensions or other universes.

Or not.
