Any Aliens which can travel to earth will have technology far greater than ours. If theses aliens have any form of weaponry, it will also be more advanced than us. We would probably considered the level of early man or even less. It could be they are so advanced they would have GOD like powers or technology. If this is the case, they could probably wipe out the whole human race quite easily. We have been broadcasting signals into space for over a century. Just to give perspective, it takes a radio signal 5.5 hours to reach Pluto (4.9 Billion miles or 0.0006228 light years from earth) which means approx. 10 hours between communications. At 100(ish) light years away, aliens would be receiving broadcasts from earth from around 1950's, that's 70 years ago! Right now, aliens would be watching the coronation of Queen Elizabeth II broadcasted in 1953. If E.T. could phone home, he'd have a long wait for any reply.

You argue 'god like powers' then restrict them to the speed of our technology.

You seem confused rather than curious.

Description

The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. Wikipedia
N=R_* \cdot f_P \cdot n_e \cdot f_l \cdot f_i \cdot f_c \cdot L
N = number of civilizations with which humans could communicate
R_* = mean rate of star formation
f_P = fraction of stars that have planets
n_e = mean number of planets that could support life per star with planets
f_l = fraction of life-supporting planets that develop life
f_i = fraction of planets with life where life develops intelligence
f_c = fraction of intelligent civilizations that develop communication
L =

mean length of time that civilizations can communicate

 

 

Until the 1990s every number for the Drake equation were just guesses.  Then, about 25 years ago, we started to discover exoplanets - planets orbiting other stars.  The current, and very conservative estimate, is that there are as many planets in our galaxy as there are stars!  Now, few Earth-like planets have been found, but that is largely because they are relatively small and fairly distant from sun-type stars.  However, when we consider the number of 'super-Earths' that we have found so far, it is highly likely that there are a large number of Earth-like planets. 

 

This means that Drake's Equation is no longer just a guess and that the numbers that we now know are quite favorable.

 

It is indeed a very interesting time to be alive!

While the Drake Equation is viewed as useful different scientists get different values depending on their 'educated' guesses at this time. More recently, some have questioned whether or not is actually complete. For example, the ability to live in extreme conditions. to mention but one possible addition. But of course there always remains the issue as to whether life and intelligent life, has to be life as we know it.

There are several 'drake equation' calculators on the net so if you haven't already done so check one out and put some of your own figures in.

Last chapter "Star-Child" in 2001 comes to mind...

Only 100 trillion kms. Unless there is some major breakthrough in faster than light travel !! we will never see them.

Faster than light, and actually the speed of light. both impossible for any transport. This explains it well.

Intelligent life if it is around would want to avoid us. We are pretty violent as a species and look what we did with our planet.

 

Or it could be just as violent, if not more so. Then again, maybe flies are violent, I wouldn't know - I just swat them.

 I made no argument "regarding God like powers". There was no debate however, I did say.... 

 

"It could be they are so advanced they would have GOD like powers or technology."

"Any Aliens which can travel to earth will have technology far greater than ours." 

 

Where did I, as you wrote, "restrict them to the speed of our technology"? The reference to speed was regarding the speed of terrestrial TV / radio transmissions travelling through space. Now, if aliens could bend space and time, it would take but an instant to traverse the universe or perhaps they have access to a stable worm hole and could possibly travel to Earth in minutes but that is a whole new conversation.

 

My deepest apologies if my post was too confusing for you. Anyone else need I explain in more detail?

Now I am curious if you are still confused 😉

Just imagine if we could develop a kind of space craft to send humans there, They meet up and we infect them with the COVID virus, I wonder what they would think of us ?????

That's assuming their are built along the same specs as us. And if they are at least on our technological level, then any alien (us) would be quarantined anyway.

Very cool hope we find out in my life time!

Agree, but unlikely in mine, can't say for yours!

and what if they infect us with some fancy intergalactic virus 1000 times more potent than C-19 ?  I have no interest to shake hands with any small green men 🙂

Read a NASA article that suggested had the dinosaurs not been wiped out they 'could' have advanced sufficiently to have landed on the moon 65 million years ago. Makes you wonder what is out there!!!

I hope those planets are not populated with intelligent life. Those pesky aliens assuredly would rape and pillage an unoccupied planet before attacking earth for its precious resources; unless they have a taste for humans.  Hopefully God made them all vegetarians.
