Why do we get nosebleeds? Can you use a sonic boom as a weapon? Is it healthy to sleep under a blanket? What will happen when the sun dies? Why does staring at light help you sneeze? Can a loss of memory cause hearing problems? Does throwing against the earth's spin make javelins go further? Plus, reassessing the age of the earth's magnetic field.
The sonic boom only happens when you are braking the sound barrier (not all the time). The 'russian glasses' broke when the sonic wave from the collision (the meteorite smashing into the Earth) hit them. Nice podcasts Chris :-) TheSpanishPhysicist, Mon, 3rd Aug 2015
