Extraterrestrial Intelligence....Cousins Of The Earth??

[Campbell]

The precise and periodic dimming of several stars lead many space experts to believe there are several planets very similar to our earth which revolve around and are the right distance from a "Sun" to produce life as we know it. What Do You Think?

Millions of stars, each possibly with their own solar systems, and no possibility of at least ONE of them having intelligent life on one their planets?

Planets orbiting stars seem to be the rule and not an exception. Since nothing else in the universe (including perhaps the universe itself) is unique, thinking intelligent life only occured once has no support in known astro-science. I think intelligent life is common but due to distances between incredibly difficult to detect right now. But shouldn't be indefinitely.

New Study Suggests We Are Alone in Universe
February 26, 2016 - Since the universe is so huge, most astronomers think that there must be a planet, somewhere out there, similar to Earth. But a computer model created at Sweden’s Uppsala University says that our planet may in fact be the only one supporting life.

Astrophysicist Erik Zackrisson combined all human knowledge about how the universe was created, from the Big Bang to the present, and fed it to a powerful computer. The machine came up with a concrete number of what we already knew. There are about 700 quintillion planets, or 7 followed by 20 zeros.

Earth is seen above the Moon's limb, in this handout picture taken by the Apollo 8 crew nearly half a century ago, on December 24, 1968​

The unexpected by-product of the calculation was that Earth may be unique, actually an aberration among myriads of dead, uninhabitable worlds. Taking into account all known laws of physics and our knowledge about how planets are formed, it looks like that process is capable of producing only planets that cannot sustain life in any form.

Probability suggests that just in our own galaxy, the Milky Way, there must be about 50 billion planets similar to ours. But according to Zackrisson’s model, Earth is a statistical anomaly. Scientists say that even if further research proves this theory wrong, it is true that the planets like ours are rare and very far between. The new study was published online and submitted to The Astrophysical Journal.

The rarity of intelligent life on earth would imply that it is rare generally.

There's barely any intelligent life in this thread.
