Philosophy Wire: Light out of nothing… Being out of something…

Talk about getting something for nothing. Physicists predict that just by shooting charged particles through an electromagnetic field, it should be possible to generate light from the empty vacuum. In principle, the effect could provide a new way to test the fundamental theory of electricity and magnetism, known as quantum electrodynamics, the most precise theory in all of science. In practice, spotting the effect would require lasers and particle accelerators far more powerful than any that exist now. [1] Light out of nothing. The story of our life. Existing out of the darkness. Playing within oceans of tears. Here we are. Blessed are the ones who will believe without seeing… Riding the ocean waves… Hitting the shore… Going up the river between dense forests… Passing through deserts… Only to find out that the river head was always dry…
