Did anyone check the asteroid to see if it had a disc of music nailed to its side?

Every time humanity fires something out into the deep we send a compilation along with it, but the first chance we get to see if we’ve been sent a mixtape back and nobody even bothers checking. We’ll never set up a regular tape exchange with that kind of attitude.

Also there is no dust cloud (or only a very, very light one) around it which is kind of unusual. I would say it is definately a spaceship. Maybe from a civ with a very strict prime directive regarding first contact. So they all suicided one they realised we are here.

The most important thing, if we're to fling asteroids back, is to make sure ours is bigger.

It's as if real life is providing us with a mixture of Rendezvous with Rama and Contact (up to now at least).

I'll be very interested in how this continues to play out.

Every time we detect an asteroid from outside the Solar System, we should immediately launch a mission to fling one of our asteroids back in the direction it came from.

This seems unnecessary to me. Solar systems are so far apart that they are basically never interact, meaning that they are closed systems. The Law of Conservation of Mass says that any closed system must maintain a constant mass. Therefore, whenever an asteroid enters our solar system, an asteroid from our solar system must leave. When you take into account the Law of Conservation of Momentum, then you realize that the exiting asteroid must be headed to wherever the entering asteroid came from. That's just science.

She forgot the cigar-shaped alien probe from "Star Trek 4 - The voyage home". The one that was calling for whales, and Kirk and his team had to go back in time to bring a whale with them to the future.

I think you flipped a sign in your momentum calculations, and ignored a rounding error earlier in your reasoning :P

In Star Trek 4, I never understood why the alien probe came to Earth looking for whales. I mean, it was stated to be from really far away, and from an utterly unknown civilization, right? How did it know humpback whales lived on Earth? How did it know what they sound like, and why did it think it could communicate with them? They actually did communicate, at the end, but how? The probe didn't appear to have any kind of boom microphone. Did the whales have some sort of underwater transmitter that they used to transmit a signal through space before they went extinct, and the aliens were attempting to respond to that? Did the aliens get information about the whale's existence from some man-made source, only to ignore the possibility of communicating with the humans that created that source? From a production point of view, I think the probe was intentionally mysterious, like they never really even said if it was robotic or some kind of alien spaceship with living things inside, but still, their behavior is way out of line with typical Star Trek aliens.

New User wrote:In Star Trek 4, I never understood why the alien probe came to Earth looking for whales.

A prior probe had clearly found Earth in the past and established that there was intelligent life in the form of the cetations (so sometime well within the last 50 million years). Probably made contact1. It had not detected, realised or cared about intelligent life on land (see footnote 1 for the possible species bias) and may even have left a Monolith-like device behind that we never discovered or identified as such, but somehow imbued the cetations with a racially-usable walkie-talkie (that no whale had ever told us about, because we never realised we could/should ask about it?) and/or passive monitoring to see when Uplift might be ripe for the making.

Whales die out, communications/'heartbeat-monitor-thing' go silent, presumed catastrophe! Probe sent with aqua-tech ability to project communications into water (pretty intense, dangerous to unhardened Atmosphere-Dweller tech) to try to work out why their pet project had gone into decline. Or were coming back anyway to see if their equivalent of 2001's Moonwatcher had developed, their probing aquatech features receiver-capability (resonant-backscatter of the projected signal, like "laser bugging" of windows?) and, again, things worry them. Or this is just their inestigatory probe's programmed response ("Try harder until contact is made; No effective limits to power usage, so long as the oceans don't actually boil away."),

Whether George and Gracey actually heard "Whale friends, whale friends! Please respond!" and replied "Hello probe, of whom i learnt under my grandmother's fin. We are here. Sorry, things were tricky and desperate, but we're alright now (or so this little land-moving guy we trust told us straight to our mind!), please could you not shout so much? We'll talk later, maybe…", I don't know.

It could as easily have been the equivalent of a safari-park ranger approaching a worryingly motionless monkey and prodding it with a stick to see ifit was dead, and happy enough to get it to wake up from its slumber and yowl a general complaint about being dusturbed.


Though all that is just a set of guesses. I know there's other ways to eff this deliberately ineffible monstrous MacGuffin.



1 I'm clearly supposed to presume that this space-faring species are themselves aquatic, probably on an ocean-dominated planet, despite the popularised idea that technology and even cooking of food cannot exist in an environment where fire (natural, at first, then self-made) cannot happen. Though it's conceivable that food just never was a problem to which cooking was a brilliant solution, and industry based around volcanic escapes might have sufficed too. Then there's the problem that dealing with outer-space level one (surfacing to the atmosphere around their ocean, and/or into the ice-crust a la Europa) is one thing, but then they need to discover the limits of OS1 to get into OS2 (actual space), which requires development of further technology. More so than we, who have long seen flight in natural use, progressed to (fire based) rocketry to escape the atmosphere we pretty much knew all about, though conceivably a development of impulse-like technology (perhaps bio-mimicing?) within the ocean-fluid might have led 'easily' to an air-pushing version, and a Sufficiently Advanced Technology which just imparted inertia upon the craft itself (already a Trek-universe technology, give or take) may well have avoided all the messy Big Dumb Rocket stuff of pushing mass out the back (whether drawn in the front or not), and so found application even out into Outer Outer Space. Right?
