If a dyson sphere were built (!), could the energy be stored and used over time? Or would all the energy have to be consumed immediately?

Does it ever happen that a “newly discovered” species has already been discovered? What's the process to ensure that a new species is really new?

What caused (cosmic) inflation to take over at a certain point, and why couldn't that process later reverse itself?

When I use a coffee pod (K cup) more than once, the water still comes out brown, but decreasingly so. Is caffeine content somehow proportional to color? (e.g. adsorption of light?)

If I heaped enough iron together, would it collapse into a black hole? Or is the shock of the supernova also needed?

In principal, could all our genetic material be put onto a single chromosome and still function the same?

Suppose you're standing at the height of low earth orbit -- but you're not orbiting (say you're in a space elevator ). What is the acceleration of gravity acting upon you -- what fraction do you weigh ?

Is there a portion of the sun that is either liquid or solid? (If not, can I reasonably claim that the earth is bigger than the sun "if you don't include their atmospheres"?)

Taking the popular "tennis ball bouncing off a train" analogy literally (with the satellite as a tennis ball and the planet as a train): are the effects of a gravity assist on the orbits the same as if the satellite had literally bounced off the planet surface at that angle?
