2. Black Holes Black holes likely emit radiation
Radiation probably not seen
Called Hawking Radiation
Hawking radiation involves particles being pulled into the black hole & joined by virtual antiparticles – usually are destroyed,
But sometimes the two halves cancel out each other almost instantly – they then can pop up outside the even horizon

3. Jess Steinhauer with his black hole machine
Uses rubidium atoms to show a form of matter called Bose-Einstein
The radiation can be observed by human eyes
Uses lasers to create a sonic atom waterfall.
Phonons (Units of sound) don’t escape past the waterfall

4. Black Holes Steinhauer did not use an actual black hole
Analogies like this experiment are useful
Radiation is observable
