What if mining too much of the moon throws off the gravitational balance between it and the Earth, or maybe just messes with the tides?

Einstein's famous equation, E=mc^2 is wrong otherwise garbage also can be used to make nuclear bombs as long as it is matter or it has mass. Energy and matter can't interchange one another according to Einstein's famous equation. One must have photons before one can emit out photons. Photons are particles and they have mass. The law of conservation of matter and the law of conservation of energy are right. Whereas the law of conservation of energy-matter is wrong. Therefore fusion process even if it is feasible but it will fail  to produce additional energy. Because to build a larger nucleus, we need to saturate those nucleons with more stationary photons, instead of releasing out additional photons to the surroundings. So there is not even any trace helium has been detected in any tokamak reactors all over the world until to date. This implies that fusion process is just impossible to take place on earth. Even if it could, it would require lots of photons rather than releasing photons to the surroundings. Fusion process is feasible during the "final" implosion of the entire universe where there is high saturation of photons pools around the center of the universe. With the presence of high density pressure (acting forces from all directions towards a single spot due to the presence of strong gravitational forces of the celestial body), smaller, simpler nuclei would be fused to a larger nucleus at the same time their nucleons would be saturated with abundant photons that are readily available at that  time. So many dense and very dense radioisotopes will be churned out. As the universe continues to expand after Big Bang, angular momentum of nucleons would be used to do work against gravity to fuel expansion. The weakening of angular momentum of nucleons of dense and very dense "radioisotopes" would weaken the stability of nucleus and subsequently causing decaying and dynamic photons would be released to the surroundings. Therefore this is how and why all stars are emitting out heat and light through fission process rather than fusion process. Precisely fusion process has been misunderstood. If you like to know more about fusion process, I have just published an article on fusion process on my Facebook on 18th June, 2018, and you may read that. If you  are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust. .

If fusion energy becomes viable we need to get rid of all nuclear reactors and plants. In a situation where humans cannot operate these they will explode, causing long nuclear winters.

If we're deciding which power type to use, just think about the one that will help space travel. Solar panels are effective closer to the sun, where we are, and weaker beyond the asteroid belt. There's no flowing fluids in space so wind and water are out. Geothermal isn't made for space, and fossil fuels are inefficient. Our only three options, uranium, thorium, fusion. Uranium is as rare as tin, thorium is better than uranium in every way, except for bombs, and fusion produces the most power.

Seems to me that if fission releases huge amounts of energy, then fussion would require huge amounts of energy for the same mass. I've yet to see anything that says otherwise. Spend the money building orbiting solar panels that collect energy, transmitted via microwave, etc. and shade the Earth to help cool it off.

Did you know your penis head is shaped the way it is to create a vacuum in the vagina and to compress that space to push your sperm further up the uterus? which means.. if you thrust hard and fast enough your semen can literally provide energy for the earth. I mean, your spouse might implode but that's a story for another day.

DarkPhoenix (10 дней назад)
I wish Fission reactors were more of a viable option until cooperation scared the public into thinking a meltdown is likely.When in reality it isn't that likely and fossil fuels have killed more people than all nuclear reactor related deaths.Also quick question,I know more heat for a fission reactor is a good thing because it will produce more energy but is it the same for fusion? If it is then why haven't they tried using a really hot material like magma to produce greater yields to see if it's then a more viable option? Probably wouldn't work but just throwing ideas around.

There is a minimum limit on energy produced when the fusion will start on being profitable, calleb break even point Q. When the breakeven point is achieved, the reactor can continue the fusion with the energy it has produced and thus starting to make "unlimited" energy Q >> 1, but of course there are other limiting factors. The test tokamaks have already achieved ~60% of the break in point and the I.T.E.R should achieve Q>10 when tested. So we may really not be that far now.

It is not unlimited, as to get energy from fusion, some mass is expended, so over time you would have to add fuel.

shoot h with a neutron gun to make deutirium and tritium
STDrepository (26 дней назад)
to build a large capacity fusion power plant would mean probably half a kilogram of deuterium and helium plasma swirling around at 150 million degrees. You say thats not a bomb?? If you crack open the reactor vessel and air rushes in its quite literally a nuclear bomb.
STDrepository (4 дня назад)
if you expose 500g of material at 100 million degrees to air at room temperature it will instantly explode like a bomb. The air will expand hundreds of times faster than the speed of sound. Faster than TNT, faster than C4 faster than any conventional explosive because its a thermonuclear blast.
Alejandro Agudo Sánchez (4 дня назад)
The temperatures reached in the plasma are incredibly hot (100 million degrees Celsius and more), but the density is so low (and thus the amount of molecules so small) that a malfunctioning reactor would just end the fusion process.

the fusion core is not as safe as thees video makes it sound sins fact expending gas is an explosion yes compered to a nuklier reactor its safe but not as safe as wind turbines or fossil flues (English is not my fearst language sorry if there are some gramer mistakes )
Remind (19 дней назад)
Great that you love fusion. I was commenting on your remarks regarding wind turbines and fossil fuels, which are less safe than nuclear fusion. Your comment seemed to indicate that you thought otherwise.
Golden Boss (19 дней назад)
Remind you bent my words so gud i didn't say anything like that i love fusion but it's not as safe as the video implies.
Remind (19 дней назад)
More people die from falling of wind turbines than from nuclear accidents (by which I mean nuclear fission accidents, like Chernobyl). Besides that, fossil fuels kill literally millions of people every year, so that is definitely a no-go. Nuclear fusion reactors, as in magnetic confinement reactors, like the ITER tokamak being built in France, are very much safe. The temperatures reached in the plasma are incredibly hot (100 million degrees Celsius and more), but the density is so low (and thus the amount of molecules so small) that a malfunctioning reactor would just end the fusion process. This is actually one of the main problems with fusion reactors today, that the reaction cannot be maintained long enough to get to break-even energy (more energy out than in). The worst thing that could happen is that your freshly built, billion dollar worth fusion reactor really breaks down from unexpected anomalies in the hot plasma, and there goes years worth of work and money. But no huge explosions whatsoever, they are immediately contained because the gas cools down extremely rapidly.
