8th April 2011 Larger Teleporting Molecule Found

Where is the boundary between quantum and classical mechanics?

1999 Anton Zeilinger and his team at the University of Vienna found that buckyballs (60 carbon atoms) had properties of both waves and particles, a distinctly quantum trait.

2011 Stefan Gerlich, Sandra Eibenberger, Mathias Tomandl, Stefan Nimmrichter, Klaus Hornberger, Paul J. Fagan, Jens Tüxen, Marcel Mayor & Markus Arndt find 430 atom molecules which teleport.

7th April 2011 "What Every Dog Should Know About Quantum Physics"



"What Every Dog Should Know About Quantum Physics"

Tunneling - when a particle manages to get where it shouldn't be, like through a barrier.

The sun is only 10 x 106 K but in order for fusion to take place the temperature would have to be 15 x 109 K. But we know fusion occurs so how can it? The two nucleii get close together, but then they don't have the energy to get close enough but that's ok because they tunnel to get to each other.
