It is very exciting to see data come in on a subject like this, but as far as I am aware it takes immense amount of energy to truly communicate intergalactic not to mention the time difference. I admit I'm not up to date on this matter. I've bin more dedicated with the working of quarks and vacuum energy. Unless the Aliens have figured out how to tape into this unlimited source of energy I would suspect that the finding have to do with some other phenomena. But thanks for reporting it.
