i know that space is still expanding, so it can never end, but there is an end somewhere but what i dont get is what is it like water?
God made 2 waters to sepiert the world (space, suns everything) and a water here on earth to be a home to fish and water creaters, so is it like water, or glass or Gods hands?

What are your views on time travel? Do you think it could be achieved by going faster than the speed of light? Personally I think that if we could travel faster than the speed of light we could slow time down for ourselves, and we would remain unaged while others continued moving and aging at a natural rate, but I dont think we could actually revisit Earth as it was at a previous time, and if we could, simply our presence there would alter the future, so we could never return to the time that we are accostomed to. What do you think?

Y = Wave function

A quantum system has a measurable property represented by the observable S with possible eigenvalues nh,where n = −2, −1, 0, 1, 2. The corresponding eigenstates have normalized wavefunctions Y n. The system is prepared in the
normalized superposition state given by

Y = 1/N [ Y-2 + 2Y-1 + 4Y+1 - 6Y+2]

where N is a normalization factor.

1.Calculate N

2. Write down the probabilityfor each of the following measurements of S
-h, 0, 2h

First off, I DO believe that there are people with amazing spiritual gifts, (I actually have a couple of them in my family). That being said, Occasionally I will watch Montel when nothing else is on, and it seems like Sylvia is always on his show, she just sits there scratching her hair with those dragon claws growling at people. It's so obvious she is just guessing answers for people, maybe she was psychic at one time in her life, but I believe her "gift" (if there ever was one) is GONE now. She needs to stop playing with peoples emotions (And hard earned money). She has already been proven wrong NUMEROUS times, I don't know why Montel insists on having this fraud on his show constantly, it makes him look just as shady.

Dimensions and mathematics go hand-in-hand, and are - what, scientific observations, right? Therein lies my belief - they are simply observations of our surroundings. Dimensions are simply perspectives to classify objects, no? Sure, time and space supposedly existed long before humans were here, but we didn't know that before we came into existence, so how can we ever know? And where did this idea of higher-level dimensions even originate from?
