The Coincidences of Oumuamua

Why wouldn't they just come here and say "Hi guys, we saw your lights on, so we thought we'd drop in and say hello to our new neighbour. Sally has made an apple pie for you".

Is that how we greet the ants, when we decide to bulldoze a lot with an anthill, for some new condos?

Then again: the ants would probably enjoy some pie.

Pretty crappy alien probe to just blow through the solar system like that, seems like an awful lot of work to just blow through and do nothing. Wouldn't they make it orbit the earth or another planet at least?

Why waste the fuel. They showed up, saw there is no intelligent life in the system and blasted off to the next potential candidate.

No worries thou, we still get 2 attempts

This thing came in tumbling end over end,

Not really end over end. More complicated, chaotic.

No single rotation period can explain the exhibited brightness variations. Rather, 1I/‘Oumuamua appears to be in an excited rotational state undergoing non-principal axis rotation, or tumbling.

Yea, like spinning in one axis and tumbling in another. The weird part is that, say trying to turn a spinning bicycle wheel 90d opposite the rotation, it resists. Would not one spinning axis tend to stabilize the other(s) eventually over time?

No, more like not rotating around either physical axis. The rotational axis is somewhere between the two physical axes.

I remember an old Skylab video showing an astronaut sailing a rectangular box across the cabin in zero-gravity. Rather than just tumble end over end, it also included a longitudinal axis spin that made it rotate as it tumbled. Flip and spin. That's just the way it works, apparently. I can imagine the same thing happening here. Wish I could locate that video, but it's pretty old.

Oumuamua is a rock
Nothing more , nothing less.

K, I will try again to wrap my head around this kind of motion... so a general area representing a non-precise center of gravity that accommodates 2 simultaneous rotations.

a reply to: charlyv

No. One rotation around an axis which aligns with neither the longitudinal or lateral axis of the object.

a reply to: Phage

oooh. spooky. Seems that it would self-stabilize itself somehow... or come out of it, as it were. Something tells me that is wrong as well.

Dynamically stable. It just looks weird.

Precession on steroids? Does that help?

Yes, that makes total sense now, albeit seemingly visibly more pleasing!
Thanks.

Bradley assault vehicles, Abrahm tanks, Mujahideen warriors, Nepalese Ghurkas, Raptor fighter jets, Russian nuclear arsenals, British SAS, Nimitz class carrier groups, Seawolf submarines, 8 billion humans chomping at the bit for a common enemy.

Stuff like that can be off putting to door-knockers.

2. The maximum speed at the closest distance form the sun of Oumuamua is 196,000 miles per hour. This is with in 5% of the speed of light divided by the magic number 3600. This just happens to be the number of seconds per hour.

huh? Could you elaborate on this..

Peace

And in accordance with Planck's constant one must then divide by 7 with 7 being the atomic number of obfuscation.

You only get one star.
Not three.

Kinda pointless if they simply stop all your somatic nervous systems.

All that hardware and all those humans just sitting quietly for their apple pie.

Or perhaps they could just implode the Sun then all those eight billion idiots could get the glorious pointless death they so desire.

Of course, anyone who can travel as far and as fast as they can, would be so far advanced that they really wouldn't react in fear like you hope.

By increasing its mass?

Easy peasy.
