This is my first post and I have no formal physics background, so please be gently with me. :smile: I'm looking to get a better understanding of the effects of gravity on light and time. From what I've read (if I didn't misunderstand) a gravitational field will bend light to some degree. This...

You and a friend synchronies your watches. Your friend gets in a rocket ship and blasts off. He manages to get the ship going to 90% speed of light. You use a telescope to check out his watch. To you it looks like it’s running slow. When he lands back on Earth you check both the watches and see...

If you'd be kind enough to answer my qeustion, thanks. I'd like know what are the effects of alcohol on the brain? Permanent and temporary

This is an unusually important question. Could one determine the approximate age of a manufactured bismuth/magnesium/zinc composite somehow by the effects of UV, cosmic rays, or some other type of energetic particle acting on the material? For example, by microscopic examination or by some...

I have got many questions: 1. Is the anywhere that gravity is not present? 2. If there was two planets of equal size and mass, they were a distance apart. And an object was equal distance from both would the influence of gravity cancel each other out therefore making this an area gravityless...

i have been wondering... 1)how does gravity induce a thermodynamic reaction (specifically) 2)can the behavior of gravitons be predicted or are they virtual particlely (specifically: can they be controlled in the same way other sub-atomic particles can such as the...

hi,i have two questions i hope you can ansewer. what is the process that initiates star birth? how does gravity focus on a single point,that attracts space debris to eventualy form a star?

[SOLVED] Effects of a massive object on light and its relation to the 1919 Eclipse What happens to light as it passes near a massive object and how it this principle or concept connected to the 1919 lunar eclipse where Einstein’s Photoelectric theory was proved (both the apparent and actual...

Can anyone explain what is blue shift and red shift?? And what effects they have?

hi i'm working on a program to simulate the effects of a golf shot accurately. I allow the user to set most of the parameters - such as the mass of the clubhead, loft of the club face (angle), the radius and mass of the ball, etc. At present, I've got a pretty lame implentation, which...

Hello. I was just at the super market, and i saw a drink which is supposed to give you "energy". It is called "Power Horse". Although it is very expensive (imported from Austria), i decided to buy it. Now, i don't really like the idea of drink that gives energy, therefore i suspected in its...

No, I'm not referring to the latest anti-Canadianism going on in the B(eautiful)US of A. (Actually that's all a cover for our special-ops... from the JTF2... who have been in Iraq for 2 months preparing the way for what was supposed to be a quick change of regime (and lube and filter). Yes...
