Re: Many Questions

In answer to your questions Erik

1. How much energy (exactly) is required to start a fusion reaction.

I can not say exactly how much energy is required as it depends on a many factors. It takes a temperature of over 100 Million degrees Celsius to make Hydrogen to fuse into Helium. It also requires very high pressures, in the Mega Pascal range. Fusion of a sort regular occurs in particle accelerators, the energy required in these interactions are in the order of Millions to Billions of Electron Volts. For more info see the JET pages

2.Does light have a electromagnetic resonant frequency, and if so what is it.

I am not sure what you mean by an Elctromagnetic Resonant Frequency. Resonance is an effect where a wave interacts with something that has the same wavelength as it. It is used in musical instruments to great effect. Resonance is also the effect used by opera singers to break glasses. The glass has a natuaral resonant frequency. When the singer hits that frequency, the glass vibrates and then breaks. Resonance is also a problem to bridge and chimney builders. If the wind hits the structure at just the right strength it resonates with disastarous effects.

It is wrong to say that Light has an Electromagntic Resonant Frequency. Light is an Electromagnetic wave itself, can have many frequencies, and does not `resonate'.

3. Can gravity be produced artificially by the use of high powered electromagnetic fields, and if so how and why.

A simple answer is no. Gravity and Electromagnetism (EM) are different forces and one can not produce the other. Gravity is caused by a mass `bending' space. One way EM waves are produced is by electrons in an atom becoming energetic and then releasing the energy as a wave.

4. How much force(in relation to mass) is produced by a thermonuclear fusion explosion?

Only a few Kilograms of material are used in Fusion bombs, and the force of the explosion is in the Megatonne range. In actual fact only a small percentage of mass is converted to energy in a fusion bomb. The efficiency of a fusion bomb is only about 0.1%. If the bomb was 100% efficient, 10 Kg would release energy in the order of 10¹⁷ Joules - several billion times more powerful than a conventional bomb.

Hope this quick precis helps answer your questions. I would reccomend reading an introductory Physics text on Light and Gravitational theories if you wish to understand this some more.
