I confess to being markedly ignorant in the realm of astrophysics, but to a layman, I'm not seeing the big deal here and I'm certainly not seeing this as evidence of ET life.

eh...likely not ETs but fascinating none the less.

For all *intents* and purposes. Damn I hate to see that mangled.Please correct me if I'm wrong ( and I know you will) our little galaxy is 100 thousand light years across . If we could travel at the speed of light it would take us that 100 thousand years to get across to the other side. Deep space travel is far beyond any capabilities we have or will have, perhaps in the entire life span of our planet. We can't even withstand the environments of space long enough to travel to our neighboring planets let alone deep space.
There are more galaxies in the universe than there are grains of sand on every beach on earth. The logical conclusion is that there are probably millions of inhabited planets but we have to conclude that they are subject to the same physics as the rest of us. For all extents and purposes we are alone.
Have you seen Interstellar yet? Opinions?If the signal originates 5.5 billion light years away, it is almost a certainty that any civilization that sent it is long gone. Our planet had not even come into existence when it was transmitted.
As for travelling to other distant locations, if we could create a ship that approached the speed of light (an almost certain impossibility), relative ship time would be drastically different than what we experience on earth. A ship travelling a 99.9% the speed of light, causing relativistic affects, could circumnavigate the know universe in approximately 54 ship years. However, so much time would have passed on earth the ship would return to a dead star and no earth at all.
Travel through some type of sub space that would largely negate distance is a scientific possibility, but current estimations of the amount of energy needed to achieve it roughly equals that of a sun going super nova.
It is actually more likely that we will achieve interdimensional travel, rather than intergalactic travel. Interstellar travel may be a possibility some day, but the ships would probably need to be "generational" and would never effectively communicate with earth again.
BTW, this should not be in Area 51.
