Marco’s comments from the Astronomy and Space exploration group.

Interesting discussion, indeed. It's worth to remember that quantum tunneling is something very real, it's something extremely important for us, since we are alive exactly for this!

How it is possible? Just remember that stars like the Sun cannot burn chemical elements such H and He if they worked fully according to the rules of classical mechanics. Any text of stellar evolution can persuade you that temperature and density of stellar interior are not strong enough to allow particles to be so near to ignite termonuclear fusion. Here it comes quantum tunneling, allowing a small but significant fraction of particles to maintain nuclear fusion, from which it comes light and heat and the very possibility of life.

Sorry for this little digression from the main topic of the post... it's only that quantum tunneling led me to recall this ;-)

Here, to serve :-)

Thanks a lot Starman!

Sure, GAIA is working quite well and it is revealing us more and more the incredible complexity of our Galaxy... some interesting (not too technical) articles can already be found in http://sci.esa.int/gaia/ but we can surely expand some topics whenever seems interesting to do it ;-)

Greetings!

Hello, I'm Marco and I work as a researcher at the Rome Astronomical Observatory (www.oa-roma.inaf.it). My main topics of investigation are stellar evolutions and globular clusters, moreover I in the team of ESA-GAIA satellite. I'm interested in public outreach as well, and I'm glad to have found this group ;-)
