We are expecting another world to be transmitting at a power level for us on Earth to hear it. As our own human species matures on Earth our actual transmitted radio waves have been getting less powerful as we both perfect radio transmission and move away from radio transmission to fiber optic and other terrestrial types of communicating. Probably our highest powered transmissions into outer space was when we exploded Atomic bombs above ground and this was for maybe 30 or 40 years total. The chances that some other planet was listening during that time would be more astronomical than there being life on other planets outside of our solar system. And, there was no intelligence in the explosions for another planet to believe it was from intelligent life. The white noise of our universe that AT&T first heard 60 years ago is from billions and billions of hugely powerful star events that would easily wipe out all life on earth if we were just a few light years away from the smallest of these events.
So thinking that we will be able to hear evidence of life outside our solar system by listening to radio waves that make it to earth is a little far fetched though not impossible. I don't think we should stop for there might be some form of galactic space travelers that are purposely transmitting to earth a welcome message or such though if they have the technology to do so I don't think the human species will be able to understand it yet.
But, I think we as a species needs to accept the fact that space travel is the only way we will preserve our human race. This earth is doomed as our star has a limited life span. I know it may be millions or billions of years before the sun eliminates life on earth but it will happen. The sooner we accept this the sooner we will be ready to make the leap into outer space, that or die off as the sun dies off.
This country no longer is controlled by the citizens. At least at my state level I can vote on certain state initiatives but I did not get a chance to vote on the Health Care Plan and the Health Care Plan will wind up costing me more than any state initiative. Just as Bush was given the green light for going to war from the big defense industry, Obama was given the green light from the health insurance industry, who by the way the health insurance industry will gain the most as the 30 million or so people that don't want insurance or was just managing to put food on the table for their family instead of paying high insurance rates will now be forced to pay high insurance rates and let their family die of starvation.
Obama did not get the chance to design the right health care system for the right one would limit the public health insurance options. There was billions of dollars spent behind doors that we voting Americans will never see. The people in control will never show themselves. They hide behind their money and corporations getting richer and richer all the while our jobs are going overseas, our gas is getting more expensive and the security of our families is going away.
