Are we alone

Also, if there's intelligent life out there it still would probably not be able to avoid the Einstein barrier, eg. it could not travel faster than light and hence would need a truly astronomical number of years to even get here from their home planet.
And if a species could live that long, it couldn't develop as highly (for generations and generations are necessary for life to evolve). Sure they could travel for generation after generation after generation on some spaceship, but that raises questions a) about energy and supplies (there's no reststops in space) and b) why would they do that.

Einstein recanted his light speed barrier theory agreeing with Poincare Lorentz aether theory.
