I bet there are classic questions out there, they have probably been bothering scientists for generations and still unsolved. Can anyone identify some interesting ones, and see what the Redhotpawn Science Forum can do with them 😉
In my view it certainly provides evolutionary potential at least.
Any views? or up to date publications I may have missed?

Interesting read, thanks :0)
FYI
If you are interested in transposons, Michael Gillings publishes papers on this area of research....... its his major field of research.

so it must have its uses.

Stop having a go at them

since light cannot escape the gravity of a black hole, could a supermassive black hole "grab" a beam of light and reduce its speed to zero? If so, what would frozen photons look like?
P.S: This is true for all black holes, supermassive or otherise - the less massive the black hole, the smaller the event horizon, but you still get an even horizon.
