I watched some programming recently that discussed the role magnetism has played in the formation of galaxies and it was quite interesting. It seems that magnetism has played a far more important role than previously thought. I wonder whether magnetism can be used in some future form of propulsion for space travel.

Bob,

All you have to do is figure out how to cross magnetic lines of flux.

I don't think there is any such thing as dark matter or dark energy, I think that what keeps the galaxies glued together is gravity and a measure of magnetism.

I also saw a programming about that only yesterday.
There are lots of magnetic fields in our galaxy that can be used for propulsion.
Research is already underway.

The Euclid spacecraft, designed to look for dark energy, built by ESA with NASA support has been approved for launch in 2020. Wait and see.

It took 50 years to confirm the existence of the Higgs boson Now another boson has surfaced in the LHC data. I hope this is the first hint of the existence of a graviton.

Keeping with the thread title, what is the relationship between the Higgs boson and electromagnetism?

It is a quantum of the electroweak field.

We may not have to wait 5 years tullio the Chinese have successfully lunched a probe into space to detect Dark Matter

Yes, it is an Italian spacecraft called DAMPE which looks for dark matter, not dark energy.There is a good cooperation between the Italian research centers and the Chinese Academy of Sciences. Roberto Battiston, a physicist who is now the head of the Italian Space Agency, is often visiting China.

maybe...

but you also haven't accounted for the lack of mass in Space...or lack of energy also...

Space is space. An interstellar void. There is nothing there. In fact space is not completely empty it has the solar wind, cosmic x-rays, Space dust, Neutrinos, and Gravitational fields.

like I said...even if you prove that lack of gravity is magnetism...& disprove Dark matter...

you still have to disprove Dark energy in Thermodynamics of Space! ;)
