The story of 'Oumuamua, the first visitor The Mysterious Interstellar Object Oumuamua 1 week ago   13:25

In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" -- raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar.

Interstellar space isn't sending their best.
Adam Schmidt
get evidence of something cool....then do a ted talk.

First visitor we know of *

These scientists & their demonic pagan god worship disgusts me.
Do you really Trust NASA & the Government? NASA = To Deceive
C'mon people. You need to use your mind & not just take in and believe all these scientists tell us.
The simple fact that there is not one real image of "space" & our "galaxy" should instantly raise your BS meter.
They describe all these things in so much detail but show us Nothing...Wake Up People & seek the TRUTH.

You say it was a rock...but from that image caught on the telescope, what if it were an alien spaceship, is that really not a possibility?

Why wasn't Omuamua caught in our sun's gravity?

It's the "Zentradi" scout.

It’s a space turd from Joe Dirt
yeah yeahyeah
Her breathing really bothers me.. I hope she's okay tho :/

They were NOT the 1st to say hello. All of our ancestors have proven that at least 2 dozen times over. American Scientists always shot thoughts down they do not agree with. We have never been alone in the universe, anyone who thinks so, is a Blithering idiot.

Abraham Loeb, Chairman of the Astronomy department at Harvard and one of Time magazines 25 most influential people in space has doubled down in disagreement with this TedTalk theory.
The math relating to this object does not suggest "interstellar, long, skinny, crazy-flipping rock."
WAR 0826
It was just using are star as a slingshot. On the way by it said Nope!

Ted is not a credible source of information.

What a waist of time
