Spooky Physics

3. our universe might not be as stable as we think and could decay into something new
4. matter that cannot be directly observed
6. the strongest and brightest explosion in the universe, generated through the formation of black holes
7. the science behind glow in the dark stuff, Einstein won the Nobel Prize in 1921 for explaining this
8. a hypothetical region of spacetime that cannot be entered from the outside
9. an advanced civilisation with enough computer power could run this in such an elaborate fashion to create artificial minds
11. a region of spacetime where gravity is so strong that nothing, not even light, can escape

1. a potential end for the universe due to infinite expansion
2. two particles billions of light years apart can be intimately linked
4. maybe many alien civilisations do exist but they are silent and hostile, protecting themselves from other potentially hostile civilisations
5. the solid form of CO2 which can be used to create a spooky fog effect
10. a barrier to development that makes our chances of finding intelligent alien civilisations extremely rare (have we already encountered this...?)
