And what about the hundreds of billion of other galaxies we can observe? We know that the Tabby's star ETs like energy a lot because they went to a lot of trouble to capture some, but if energy is so valuable why do the ETs in other Galaxies let all the energy from billions of suns in their Galaxy radiate uselessly into empty space?</font></div><div class="gmail_default"><br></div><div class="gmail_default"><font size="4">If ET existed the night shy should look very different from what we see, there should be a Dyson Sphere around every star; no sun should emit visible light, or ultraviolet, or X ray or gamma rays; suns should only emit microwaves and maybe a little far infrared. But that's not what we see. So why doesn't the universe, or at least the galaxy, look like its been engineered? Either ET does not exist or he does but he's a lotus eater. And a lotus eater wouldn't build something around Tabby's star.</font></div><div class="gmail_default"><font size="4"><br></font></div><div class="gmail_default"><font size="4"> John K Clark</font></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div> </div></div></div></div>
