I heard that the universe/space-time was a hypersphere ....

.
If the universe was finite...then there must be a boundary obviously between the outside of this hypersphere and the inside...

So if it were somehow possible to rip a hole in space-time...and step outside of this hypersphere...

????

Could I exist...is this even possible


Is it possible to rip space-time...I don't really understand what it is...I understand two building blocks --particles and waves...I'm having trouble understanding what this spacetime really is

then why would 2 stars orbiting each other not gain energy? If gravity traveled at the speed of light (sol) they would gain energy because of the delay in the sol. Draw a picture if you don't see it. This violates the law of conservation of energy. What is your answer? Newton calculated the orbits of all the planet using instantaneous gravity, and so far none have been lost.

Am following some internet instructions to create iron-oxide. However there appears to be an error. Instructions say to attach a nail to the positive lead of a 12v power supply and submerge the nail and the negative lead into saltwater overnight.

Following the instructions to make sure you know positive from negative, I have a 12v dc power supply. I have put both leads into saltwater and the positive lead is supposed to bubble. I then am instructed to put a nail on the positive lead and overnight this will form iron-oxide. The problem is the negative lead is creating bubbles. So my question is as follows. Is the negative or the positive lead supposed to bubble? and which lead should the nail be attached to?

You are dreamy and mystical, with a natural psychic ability.
You love music, poetry, dance, and (most of all) the open sea.
Your soul is filled with possibilities, and your heart overflows with compassion.
You can be in a room full of friendly people and feel all alone.
If you don't get carried away with one idea, your spiritual nature will see you through anything."

what is the answer to 6+4 times 10= ??

Take the quiz and find out:
http://www.blogthings.com/whatplanetshouldyourulequiz/

My results:
"You Should Rule Venus

Venus is a mysterious, stormy planet - shrouded in a thick layer of clouds.

You are perfect to rule Venus, because you are quite emotional and volatile yourself.
Your emotions change as rapidly as the weather on Venus, and both you and the planet are incomprehensible to others.

While you are not a logical thinker, you are quite empathetic.
You can care for and understand others, but your emotions swirl too quickly to truly understand yourself."

Like one pill for a day. It contains ALL the carbohydrate, protein, fat, fiber, vitamins and the minerals. Only water is not in there.(drink the pill with water and drink more).

I'm just looking at the specs of some used machinery and saw the above specs. Is it possible for that motor to draw 15A? I'm assuming that one of those numbers must be a typo, either it doesn't draw that much amperage or it isn't 3 phase, isn't 220v, or is actually 5HP.

Am I out to lunch?
