We know that in the core of the sun is a fusion power plant , though some say that the center of the Sun there is a vacuum .
Now in fact we can never know if we do not go there to see !
I have an idea for this almost impossible :
it comes to building a nuclear fusion reactor which , instead of containing the plasma of millions of degrees in its interior , but it deflects outside with powerful electromagnetic fields , for which a probe to the center of the Sun penetrate gradually in the solar plasma , diverting it ...
Sorry, but I have done so if I do not see I do not think ...
Also because some recent research has admitted the possibility of the existence of negative temperatures , below absolute zero , after which there are infinite temperature ( if you are interested place the links ) leading to a circular thermal spectrum .
As for the Sun , it could well be that in its interior is cold ...

Citation needed.

Have you met science before?

You're reading about the wrong Dyson.

Ok. Maybe you intended to post this in speculations?

I don't understand the idea, can you please clarify. If the sun has a hollow core with vacuum in it's centre, then it follows that this vacuum is surrounded by some incredible strong shell/force/whatever that prevents the solar plasma from entering the void? If so, how will the probe be able penetrate that incredible strong "stuff" using electromagnetic fields?

It could be shielded by a Hoover Dam...
