Oumuamua

This blew my mind a bit: "It will take the object roughly 20,000 years to leave the Solar System."

So its been heading towards the Sun for about 20 000 years as well? Been in our 'hood for that long and we didnt know about it until it was on top of us?
 
The Solar System is likely the first star system that ʻOumuamua has closely encountered since being ejected from its birth star system, potentially several billion years ago.

Your sentiments are misplaced. Oumuamua is just a Rock that failed to pair up during planet synthesis and went rogue. I was excited for a sec lol, this has nothing to do with Alien interference.

Some objects reflect minimal light and yes Solar System is billions of times bigger than the sun. It blows my mind how an object as small as a sun can hold that much pull.

Humans have no idea about stuff outside pluto because of the same low reflections hence Oort Cloud still a hypothesis etc

Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space.

I get space is big and our solar system is big and all that. Its still all just mind boggling- the times and the distances.

While you are puzzled by the huge spaces let me rattle you with another one.

An atom's mass is 98% it's nucleus. Meaning that super compact bundle of protons and neutrons hold almost all the weight of an atom, now it gets uglier: That very same atom is mostly empty space, a super tiny compact nucleus and almost weightless electrons buzzing around it in orbits. Empty space is an understatement; imagine an empty soccer field, if the soccer field is an atom. The soccer ball at the centre is the nucleus holding 98% of the weight and the crowd becomes electrons. (so much space between the two!)

That whole gap between the two means that objects never actually touch. When I sit on a chair I'm floating(chair electrons repelling me).

Not sure you got that but yeah this universe is bloody mind boggling.

Actually, it's not empty :)

Oumuamua Isn’t an Alien Probe, Because Aliens can Learn Everything They Need About us With Telescopes​


In the Fall of 2017, the first known interstellar object passed through the Solar System, triggering a revolution in astronomy. Because of the amonolous nature of the object, astronomers from all over the world were at a loss to explain what it was. Neither comet, nor asteroid, nor any other conventional object appeared to fit the bill, leading to all kinds of “exotic” explanations.
A particularly exotic explanation was offered by Harvard Professor Avi Loeb and his former postdoc (Dr. Shmuel Bialy), who hypothesized that ‘Oumuamua could have been an extraterrestrial lightsail. Whereas most rebuttal papers questioned the evidence presented, a new study by astrophysicist and UCLA emeritus professor Ben Zuckerman questioned something else: why would an extraterrestrial civilization want to send a probe our way?
