Ok, not sure how to phrase this... but..

I saw a program on string theory, and in that program, they mentioned this woman,,, something Randall. She believes that gravity is not a force from our dimention, and that it has leaked through from one of the others.

How do we know that black holes aren't actual openings into this dimention where gravity would be a strong force?

For problems 11 through 13, a projectile is fired upward with an initial speed of 800 feet per second. It is given that

h=-16t^2+800
(h= height of the ball)

11. factor the equation
a. h=t(-16t+800)
b. h=(-16t)(t-50)
c. h=(-16)(t^2+50t)

i put a as my answer but i dont know if it is right.

12. What will you set h equal to in the equation to find how many seconds it takes for the projectile to hit the ground?

a. h=0
b. h=1

13. Use your graphing calculator to find how many seconds before the projectile hits the ground. Let y1=.16t^2+800t , or factor and solve for t algebraically.

a. 0 seconds
b. 50 seconds

please explain this to me. i am not very good with word problems. i would really REALLY REALLY appreciate it!

thank you!

:]

I've seen this mentioned here about three times, in reference to the 2012 end of the Mayan calendar. Where is this information coming from? The plane of the ecliptic and the galaxy's equatorial plane are nowhere near close to coinciding or becoming coplanar, or whatever. What's the deal?
