Question: is it possible to make a miniturized sun on earth

Keywords: , , ,

  1. Cool question!

    Well, the sun provides heat and light and energy and there’s lots of things that can also do that!
    A fire, for example, can provide heat and light, but it can’t make flowers grow like the sun can!

    We can definitely replace some of the sun’s actions with other means, but at this point, we could never survive without it. We would be frozen, like the other planets that are further from the sun than earth!

  2. It’s already been done. If you think of the sun as a nuclear fusion machine, we have duplicated this but on a small scale and it lasts for just a few seconds at most.

    Nuclear fusion is where two or more nuclei from small atomic particles join together, or “fuse”, to form a single heavier nucleus. During this process, a large amount of energy is released.

    Hydrogen bombs or H-bombs work by fusion of two hydrogen atoms. Fusion explosions cannot be controlled because you cannot turn them off once they have started. If we could control fusion we could potentially use it as an energy source.

  3. Now, I’m no physicist, but I’d say: practically and theoretically no!

    The sun is a star (captain obvious!). Stars are “born” when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion (This takes a lot of force to do, and the same reason why “cold fusion” evades us! The final result is also very “explosive”).

    Hope that makes sense.

  4. That sounds like cold fusion. And Emma is right…we’ve done little bits of it. But scientists have been trying to unlock the secrets of cold fusion for quite some time….no luck yet. If we get there, it will solve all our energy problems though!!!!
