Their Actions Are Indicative That They Believe

I think humans have this flaw. We put every other animal in a zoo.
We use up resources unsustainably.
We dislike other humans that look slightly different to us.
We are more likely to be killed by another human than by any other animal.
Maybe that is why the universe is strangely silent........

Who knows whether we are similar or unique because of this.

It is impossible for the human race to clean up their own backyard, we are on a trajectory to doom prior to collisions with other galaxies, asteroids crashing into us or Sol evolving to red giant status. We know what we're like and we know that the Earth has a use life given the enormous pressure placed on it. This, coupled with our instinctive yearning for exploration means we will continue to search for other habitable options both within and outside our solar system.

Hi Shane,
Silicon based life form was a sci fi movie back in the 60's. Can not remember much else about it.
Si based life form would still be recogizable. I was tending toward something that is not.

How far does research have to go to prove a point? Just because there is very little or no evidence of alien life does not prove either way. If we find nothing then where do we draw the line?

Think about this: If alien life is found, what kind of stimulation of research activity would occur? I believe it would be massive. What are the consequences?

Cheers

It is exceedingly simple! If we do not look we will never know!

If some alien tongue licked you on the face, many would complain! Why were we not warned!

If anyone finds it difficult to understand what highly educated experienced scientists are doing, then ask questions. Better still study science for about forty years after university and then come back to me.

I am old enough to remember when all radios had valves.

The fact all you young people have smart phones is due to a deep understanding of quantum mechanics first elucidated in last centuries early years. It took until the early 1940's when some esoteric work on the solid state physics of germanium crystals led to modern solid state devices such as transistors at Bell Labs.

CMOS was invented about the time I was nearly twenty!

Interesting subject and to be honest in 5 or 10 thousands years time I think we will be still asking the same questions.

The distances are just too vast to get a definitive answer. Even if future kind could build a spaceprobe that could travel at the incredible speed of 1 Million Km per hour it would still take 5,000 years to get to the Alpha Centauri system.

At the moment all we have going for us is the very slight dimming of a stars light to suggest a planet passed in front of it. Not much to go on I'm afraid.

It is possible in the future we may find evidence of microbes on Europa or another of the Solar system planets moon but thats about it, unless ET visited us and that would be scary.

Bill.
