When the photon/partical two slit experiment is performed you get a pattern of alternating lines on the screen. I've read that in the dark area that's where the waves have cancelled each other out and in the light area is where the waves have peaked. So how can two photons or electrons cancell each other out and still not break the law of energy conservation?

What has happened to this energy?

2. 9x+3y= 1
3. 5x-9y= -7
4. 6x-y=4
5. -2x+7y=0
6. 4x+3y=8
7. 12x=2y+1

When a rocket is being propelled through space is there any limit to how fast it can go? Because the rocket is in a vacuum there should be nothing to slow it down, that being the case can the rocket increase in speed exponentially (or at least at a constant rate) as long as the thruster is activiated? It seems to me that a rocket with a continuous constant thrust would continue to increase in speed. That being said, it seems like space travel should be a lot faster. Does this have to do with the amount of fuel, or the rate of acceleration? Or can our rockets just not go that fast?

Please, read this page before: http://spaceflightnow.com/news/n0608/16planets/

Okay, So, if the proposed 12 planets in our Solar System according the official report "will be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313"...

But Is not Charon the moon that orbit Pluto? Can a moon that orbit a planet be a planet? So, why not Triton, Europa, Titan, etc can be also considered as planets? A weird question.

Also, do you think there is life in several big moons of our Solar System? I say "Yes". What do you think?

As of 2006, England is 90.9% Caucasian and 9.1% non-Caucasian, the Caucasians have 1.55 kids per woman, and the non-Caucasians have 2.8 kids per woman. Half the population are women in both groups. The life expectancy is 75 years for both groups. The death rate is 1% of the population per year. How do I figure out what percent Caucasian England will be in 2106?

Some vitamin D is produced when ultraviolet rays hit the skin. But when sunscreen is applied ultraviolent rays won't reach the skin. Does that prevent vitamin D production from outer sources excluding the liver?

6: The person who smokes Pall Mall rears birds
7: The owner of the yellow house smokes Dunhill
8: The man living in the house right in the center drinks milk
9: The Norwegian lives in the first house
10: The man who smokes Blend lives next to the one who keeps cats

The chain rule and inverse chain rule, Integration by substitution, antiderivatives. I can't see a real life problem that you would have to use all this stuff to figure out. Textbooks are good at giving a bunch of numbers for you figure ou, but in real life would we need to do those procedures for? Does anyone have a real life engineering problem or what ever that you needed to do that?

The branch is the root. Is the universe linear (flowing in time and space from beginning to end)? Can you go forward and backward in space and time? Can you step sideways out of the Universe and spacetime and look in? Yes, the Universe is all things, but what if "things" are not all there is? Is causality absolute? Does it have to be absolute if we hold that space-time is not linear? Could our universe be defined by causality and any a-causal arrangement be thought to be "outside" of the universe and outside of time? Wouldn't that be a great place for "God" to exist? How else do you create causality except from a state of non-causality? Where is the door? I want to step through.
