I have an amazing idea. We already have a artificial Sun on Earth. Without building a Dyson Sphere. If we could harness all the power of that artificial Sun. Will it be useful for space travel? And will we be able to travel at the speed of light?
But if we improve that technology will it be possibleNo. First of all, we cannot maintain the "artificial" sun for very long. I read around 100 seconds is all. Secondly, it actually takes more energy to create the artificial sun than the energy produced.
Would it be useful for space travel? Absolutely! Would we be able to travel at the speed of light? No.Nothing can travel that fast except light.But if we improve that technology will it be possible
But if we implement some system although I think we can achieve 99.9 % of speed of lightWould it be useful for space travel? Absolutely! Would we be able to travel at the speed of light? No.Nothing can travel that fast except light.
But you know that there are something's which do not obey law's. Anyways ThanksIf we create an artificial star, it requires energy. The Second Law of Thermodynamics tells us that we cannot get out more than we put in.
Fusion is likely the ideal power source for ships and our planet. The Sun converts ~ 0.7% of hydrogen into energy where e=mc^2., which is an incredible amount of energy. There have been results where fusion prototype plants have produce slightly more energy than needed to power it, but not economically. Additional technology, a lot of it, would be needed to cut the weight of the reactor for any meaningful ship acceleration.
That's what I was basing my answer on.Such as?
Or, do you mean we don't know "yet" (possible in the future)?
When you said "no" to the tokamak question earlier, I thought this was the "artifical sun" being referred to :
China's Artificial Sun Just Smashed a Fusion World RecordThe formidable reactor reached 120 million degrees Celsius for an astounding 101 seconds.www.popularmechanics.com
But if we implement some system although I think we can achieve 99.9 % of speed of light
Tell me one such thing please. Thanks.
