Hi, Today I was sitting in the train and I wondered what the motivation for a time traveler would be if he wanted to go in the past. Say that I live in 2011 and I went back 210 million years ago to see the dinosaurs, that would be my motivation. But when I would travel back to there and...

Isnt it so that Dark Matter used to be stronger then Dark Energy ? And that the universe was contracting. How is it possible to state that the universe will keep expending perhaps the strenght of DM and DE cycle.

Hi, I just read post of a supposed Physics teacher who states that the moon moves away from Earth yearly by 3 or 4 (inches or centimeter can't remember). That because the rotational force of its orbit is stronger than the Earth's grasp on it with gravity. That all makes sense. But is it no so...

Lets end this topic since my question was answered and we are in no need of needless discussions. Thank you.

Sometimes search engines can bring you needed information : http://en.m.wikipedia.org/wiki/Planck_length

Billiard balls and particles do not move in a random direction they move into a fixed direction given by a collision. That is not random and so they do not "choose" a direction move in.

Do correct me if I'm wrong but isn't it so that when a short distance would be devided into two, into infinity you would have an infinite amount of points between here and there, there by impossible to cross the distance/stream.

Some folks say they found the higgs boson

You beat me there I edited the previous comment but I was to late. In the above case of course still no light would be visible.

Absolutely logical answers which I did not think of. I did not knew a mirror would cause a loss of energy although obvious! Now assume that I would have a perfect cube of perfect mirrors and have an object in the center. In that case I would have an illuminated object for infinity. Right?EDIT...

Knowing that light goes on in infinity. Would it theoretically be possible to trap light between two mirrors? And have an infinite source of light which would require no energy once it has been trapped.

Thank you Skaperen. That clarifies it for me! Can I conclude from the above quote that that also works with the third law of Newton (every action has an opposite and equal reaction) ? Cause I always wondered if that applied to gravity.

Thank you Bloodthunder. Now one question remains for me. Is it so that when matter is close enough to each other their gravitational forces are added?

Bloodthunder you state that we are added to Earth's mass and still we have gravitational attraction on the grain of sand. Would that not make us a separate gravitational force then the grain of sand? Or is it so that all mases have a "private" gravitational force on all other masses and a...

Hello, I am no Physicist nor studying anything near this field (I study Game Development). Though I am greatly interested in Physics and try to learn as much as I can in my free time. To bad that there are only 24 hours in a day. Anyway learning that everything with mass has gravity I...
