Clear enough! Thanks

Spacetime is curved near massive objects, and when a photons moves near that massive object, it bends becuase the spactime is curved. The photon will still me travelling in a straight line, but that line is passing through curved space, which makes it look like it bends.

Well every theory has to be falsifiable.

In english, please?

Mooooooo:cool:. Competitive expell!

IMO thats not compatible with scientific method.

Yeah! There is one thing I don't undersand though. Where does the minus come from when doing the derivation?

PhD?

And the condition (IIRC) is that [math]m_ev_er=\frac{h}{2\pi}[/math].

granpa, gravity is always attractive, always! But that is not due to gravitational 'non-repulsion'. Even if they gravitationaly repelled, the attractive electrostaic force would win over repulsive gravitational force.

We know from thermodynamics that energy cannot be created or destroyed, it only can pass from one form to another. What this actually means is that all the energy that is today in the universe, is exactly the same amount of energy that was in the very very beggining of the universe, so the very origin of energy is Big Bang itself. Now if you want to take it to a more practical matter, as where do we take the energy using which we can perform our daily activities, then the answer would be through food. Food provides us all the energy we need, and that energy is released through a series of physiological processes called metabolism.

I assume there a simple answer to this: [math]Q=mg[/math] [math]m=\frac{Q}{g}[/math] A decrease in gravitational acceleration means an increase in the mass (as long as we have Q constant which is our case), so I guess its worth more on Moon!

Haio Fellas:)! Long time no see! I see things have gone pretty forward here. Glad to be back!

Except its use as a method of cooking, it's also used to reduce food toxins.

This is just the right place New Science. I'm sure you'll find a lot of debaters here about things which concern you. Cheers!

Well there are lots of IQ tests out there which are formed based on different criteria and one has to ask "what kind of IQ are you talking about?". I've done IQ's that are 15 pages long but I've also done IQ's which actually contain no more than 30 questions. And the difficulty level of the questions differs dramatically. Where I come from, there is no standardized IQ test, and until IQ is not standardized then one cannot say anything ,at least evidence based, whether the average IQ is increasing or decreasing.

There is just too much hatred and greed among mankind, and I'm afraid there's really little chance for mankind to come together and seriously try to make improvements whose result would have a world-wide effect. I assume that it's only science and scientists among which there are no signs of discrimination on any basis. But scientists aren't really the big guys who are in charge of everything.

This year I played COD4 Modern Warfare and I tell you it's quite a good game. The graphics are really good but the thing I don't really like about it the the fact that you're somehow told how to do everything. There is no room for creativity at all. Comparing Crysis with COD4, I say that in Crysis you have a lot of options, you can pick any way you like and on the other side COD4 really reduces your options. Then Ghost Reckon: Advanced Warfighter 2 was really good too. It's a tactical game and the graphics rock too. But the game I think is just the best at this moment is Rainbow Six Vegas II. It simply rock! A combination of tactics, stealth and team work followed by some real real good graphics makes the game just be awesome. I heard that Rainbow Six is bringing out Hawks soon, and they say it'll be quite a good one!

There are lots of experiments you can do with electricity in which you will have no great danger. I would suggest trying them instead!

Except the difference in the addition of velocities, measuring relative kinetic energy differs from the classical formula for kinetic energy.

Well you can't really download it, but you can use it online. It's quite simple basically! http://www.bbc.co.uk/science/humanbody/ Just look under "The Body". Hope this helpz, Shade!
