lol you watch lame movies!
Not possible to have a sun that small. Fiction writers can write anything they want, but its fiction.
Back when dinosaurs roamed the earth without their smartphones, there was a visiting professor who came by Charlottesville to talk about the materials needed to build a production fusion reactor, even if someone managed to figure out a stable plasma containment scheme. He also talked about some of the difficulties with using a fusion torch to clean up fission reactor waste. We left the lecture talking about what a great thing it would be to power our lives from wind and sun.
Not yet. The film is fiction. Check out the work on fusion reactors.
Materials have what is called an enthalpy or "rate of heat exchange" and 2 seconds is not enough to exchange a significant amount of heat from a miniature sun. The radiation, however, could do some damage.
Yes. You can build a Liden Jar which uses high-voltage electricity to create a miniature star that you can safely view and control.
who rrly knows..this quest is rad
