Well yes. You do realise we already have 4 dimensions, right? If you want to pretend bigfoots are living in "higher dimensions", as though that actually means anything outside sci-fi, you'll have to use at least the 5th. However, current theories say that there are at least 11 dimensions, possibly as many as 22, so you're best off claiming that the orb exists in the 23rd dimensions at the lowest, otherwise you might come a little too close to reality for comfort.
Cuddles, you have lots of good company in your lack of information. Time is not the 4th dimension and it had not been since the spring of 1975, where at U.C. Berkeley, the school reassigned the 4th dimension to explain bigfoot invisibility. Hawking was there to nod his approval. Time is not even a dimension anymore. That it why they call space, spacetime. They lump them together. I use the terminology of 3rd dimension to depict our 3 dimensions. I use the terminology of the 4th dimension to depict the parallel dimension once removed from ours. I use the terminology for the 5th dimension to depict the parallel dimension twice removed from ours. I use the terminology for the 6th dimension to depict the parallel dimension thrice removed from ours. Does this different from what physicists say? You betcha! Most likely because physicists lie to each other about the higher dimensions, the higher dimensions being miniscule in size, the hypercube, the tesseract, parallel dimensions, higher dimensional people, etc. etc. Physicists are notorious LIARS. They cannot come clean about anything that they think may upset their grandmother, their wife, the neighbor next door and/or their 10 year old daughter. So they LIE through their teeth on a daily basis, like attorneys. Nor can they agree about anything having to do with the higher dimensions. The higher dimensions are not spatial dimensions that can be described by a shape. They are based on frequency of vibration of a specific type of free quanta loops. Quanta loops are the pure energy building blocks for all matter. The tesseract and the hypercube, WERE DISCARDED BACK IN THE 70's. But since they are only hypothesis, they keep them around to mess with the minds of the following generations. After all, are they going to draw a Bigfoot on the blackboard and say, "Now class, THIS is the 4th dimension. Memorize it. It will be on the test." Of course not. It looks like the program of screwing with the minds of the up and coming, as well as pseudo physicists, is working very effectively.
As for arthwollipot and his unfounded allegations about myself "refusing" to give him a date for when Kaku last spoke on Coast to Coast, here are the step by step instructions for Correa:
1. get out of bed and turn the lights on
2. put some clothes on for Christ sake
3. tie shoe laces in double knots like your mommy taught you. No, don't tie the shoelace of both shoes together because you can't walk.
4. walk to computer. left, right, left, right, There you go. You can do it.
5. sit down in the chair, face computer screen, turn computer on by pushing the "ON" button
6. wait for computer to warm up
7. log onto the internet, yes you have to enter your password for this
8. go to Coast to Coast website by googling it, then left click to the "Coast to Coast" website
9. find the blank box on the home page for searches on that website
10. type in "Kaku", without the parenthesis, that is K, A, K, U, in that order, don't mix them up
11. find the last interview on "Seti"
12. left click on the "more"
13. there it is, right in front of you
http://www.coasttocoastam.com/shows/2007/11/30.html
Now, left click the hour that you want to listen to, or download the whole program. You must find it yourself, like I stated previously, because that is the only way that you can prove it to yourself as to exactly what he said.
And Kaku will not reply to your mindless ramblings about anything. He has bigger fish to fry. Like how to keep the public from discovering higher dimension people, before he can get up the guts to announce that they are very real.
And one more thing, arthwollipot has been reported again, for another Rule 12 violation
