How do we know whether or not light is actually bouncing off everything, versus light excuding out of everything? Maybe there is some sort of signal that comes from a light source that tells matter to emit photons instead of bouncing off?

Maybe it's the inverse of what we generally blieve?

for example an apple is seen as Red because other colors are "absorbed", and red is reflected. So what if it's not reflected, instead it's emitted? It only emits the red because some signal is telling it too, once the signal is cut off, it immediately stops emitting?

I know what it does, but, what is it. How dose it work. It dosent make sense, like the strong and week necular forces and electromagnatism do.

This is the age old question posed by the great Albert Einstein and subsequently stumped by this paradox, which is an indirect result of his general theory of relativity.

There is a huge amount of mass missing in the universe. Scientists believe it is dark energy and matter that makes up this difference between measured gravity and mass. Do you think it is dark energy and if so how is it created? If you don't believe it is dark energy then what do you believe it is?

Theory, according to my reading, seems to indicate that the reason gravity is such a weak force is, because it is leaking out of our universe, into parallel universes. This begs the question, whether what we call dark matter (and are unable to detect other than through its impact gravity wise), is simple gravity leakage from parallel universes?

Is it really true that the speed of an object when thrusted into the air is the same as going down to the ground.

For example, if you throw a ball in the air, is the speed of it leaving your hand the same as landing?

Also, if you shoot vertically with a gun/rifle, is the speed of the bullet leaving the gun the same when it's coming down?
(That would be really dangerous)

I'm just curious...

and would it do it before the box has been opened by an external viewer?

schrodingers cat in a box experiment states that the cat is in a superposition of states until the box is opened and observed, then it "decides" wether to be alive or dead as a result of the release of the radioactive particle.

at what point does the intelligence of the observer come into the equation? would mechanically opening the box and placing a stethoscope and tape recorder against the cats chest be enough to collapse the probability wave and determine the state of the cat? or does the observer have to be able to intelligently interpret the state of the cat?

and if the observer has to be intelligent, not purely mechanical, can the cat posess enough intelligence to collapse the wave, making the whole paradox pointless?

More importantly, I would like to share with you the Truth about the afterlife. I only tell you this because I care what will happen to you when you die. Have you ever told a lie, stolen anything, used God’s name in vain? These are just a few of God’s Moral Laws. When you die, God will judge you on the basis of His Moral Law. If you stand guilty before God of breaking His Laws, He will send you to Hell. If God is Just and Holy, He must punish lawbreakers. The good news is that God provided a way for you to be forgiven and go to Heaven. Jesus Christ died on a cross and rose again to pay the debt for your sins and take your punishment. What you must do is Repent, which means to say you are sorry to God and turn away from your sins. Then put your complete Trust in Jesus Christ. Only then will you be accepted into Heaven, not because you’re a good person, but because you’re a bad person who’s been forgiven. Please give this some thought. Your Eternal Destination depends on it.
