We are supposed to ask questions, so, I am gonna ask some. :D

Are whiteholes possible? If yes, then, why haven't we yet discovered one, is it because we don't have enough technology or anything else? If not, then, why not?

Are there more elementary forces? Can anything be smaller than the higgs boson?

And last, but not the least, will we ever have a theory of everything? What will our reactions be like when we really have one?

Hope that isn't too much. :) :D

Competition is good, but will companies like Boeing/ULA, Blue Origin, or anyone else ever have a real competitive chance against beating SpaceX on contracts, considering that SpaceX has the flight/re-use proven cargo and astronaut ferrying with Dragon and Falcon 9, which may soon be replaced by Starship/HLS and Super Heavy?

Dart, the kinetic striking of the near Earth asteroid, something... moon. Would it not be wiser to adjust the asteroid with a rocket engine that could be used for direction? A fusion, slow and steady approach?

While it probably would be wiser, the question is CAN we. A lot depends on the target's speed and trajectory. If it's heading towards us, how do we reduce the closure rate down to zero (without crashing into it and destroying the rocket engine)? If it's moving away from us, do we have the energy necessary to catch up to it?
