Philae Probe lands on comet Comet 67P/Churyumov-Gerasimenko

Re: Phiale Probe lands on comet Comet 67P/Churyumov-Gerasimenko

Wow, isn't it amazing that people have actually landed a robotic probe on a comet, to understand what it does and how it works?

I bet it was the work of some lonely "independent researcher" oppressed by the dogmatism of Big Science... no, wait. It was actual scientists, doing their job. With official badges and shit.

Funny how you trust "official" science when it does something you like, and discard it as soon at it contrasts with your pet theory.

The true sign of an intellectually honest "scientist".
 
Re: Phiale Probe lands on comet Comet 67P/Churyumov-Gerasimenko

I'll go out on a limb here and say the reason isn't the presence of predator aliens.

:lol: Well no. But Dryson who frequently posts threads about alien conspiracy theories in this forum and likely visits Scott Warings webiste UFO Sightings Daily far to oftenwill likely disagree. ;)

In all seriousness, I really don't understand how a comet can make any sounds at all without an atmosphere.

I will give UFO Sightings Daily this much: it sure explores an interesting subject. I honestly can't say what, if anything is actually true, and what is just a hoax/misidentification, but I choose not to completely disregard this type of stuff out of hand, because I don't feel qualified to do so, and come on! This is the sort of stuff that fascinates anyone who could call themselves a trekkie!

The sounds that the comet makes would have to be something that can be picked up by signal receiving equipment. Even natural space phenomenons such as quasars, if I'm correct, make signals that can be detected.
 
Re: Phiale Probe lands on comet Comet 67P/Churyumov-Gerasimenko

Sound is transmitted from a source to the surrounding air particles, which vibrate or collide and pass the sound energy along to our ears. Without any particles to vibrate we wouldn't hear the sound. If the comet is made of ice then there will have to be oxygen trapped somewhere within the comet for the oscillations in the comet's magnetic field to make a sound. Maybe not oxygen but another particle that is able to generate sound that humans cannot hear.

The size of the comet though would be able to house at least five thousand humans comfortably.

I'm surprised ESA didn't think about sending up a craft with a longer life so that it could take pictures of its journey and then relay them back to Earth when it passed by us.
 
Re: Phiale Probe lands on comet Comet 67P/Churyumov-Gerasimenko

Wut?

Vibrations (read: sounds) travel through things besides air, you know. They also travel through liquids and even solid objects.
 
Re: Phiale Probe lands on comet Comet 67P/Churyumov-Gerasimenko

So basically it's variations of the magnetic field

Funny how ice can do that.

The comet doesn't generate its own magnetic field; it's interactions with the interplanetary magnetic field, probably involving charged particles in the comet's coma.

I was being sarcastic since I've been slapped down by the establishment Keepers of the Flame every time I've mentioned something from Electric Universe/plasma cosmology. Even NASA and ESA continue to promote the "comets are dirty snowballs from the earliest days of the Solar system" mantra with every press release. Yet numerous missions and observations have debunked that idea.

Meanwhile, establishment astrophysics maintains that space is a neutral, non-conducting vacuum, and that magnetic fields can exist without an electric current. Ask any EE what he thinks of this "magnetic reconnection" nonsense. (Magnetic reconnection is the Solar system level "dark matter"—technobabble used as a blanket explanation for anything that does not fit in with the incumbent models.)

I followed this whenever I could. I love that it occurred not long after seeing interstellar.

So what're trying to say?:confused: That the comet is apparently generating it's own magnetic field (I have NO idea if that is possible or not. I am no astrophysicist!)?

Well, you've been slapped down because the ideas you primarily post are ludicrous claptrap.

I'm not sure why you argue that "establishment astrophysics" (which I suppose is a code-word for "people who actually know what they're talking about") argues that space is a neutral non-conducting vacuum. The fact that the interplanetary magnetic field forms from an induced current in a highly-conductive plasma throughout the solar system is obviously widely-enough known to form most of the freaking Wikipedia article on the subject!

establishment astrophysics

As somebody who's working in academia I honestly wish you'd quit the "establishment astrophysics" bullshit. Science generally isn't some weird club where new ideas are shunned.
It's how the process works, it's peer review. You need to prove your shit.
What you call the "establishment" (others who don't know how science works call it "mainstream science") is the mainstream because it's peer-reviewed and adheres to scientific quality standards.
It's mainstream because it's honestly the best we can do at this point.
"New theories" become mainstream after a while if they're more scientifically sound than old mainstream theories.

That doesn't happen if they're bullshit.
 
Re: Phiale Probe lands on comet Comet 67P/Churyumov-Gerasimenko

It is funny to use that term when virtually all major scientific discoveries that make up the "establishment" astrophysics – including the ones that are now weirdly dismissed as "establishment" astrophysics and the like – had an uphill battle getting there. I wonder, why aren't other fringe theories successful at it as well? It's not like there's a guy who goes "nah, these electric universe guys wear funny hats, we won't vet them!" They even let the guy with the shirt in.

Hey, can I question the establishment mechanics that put Phiale on a comet? What if my pet calculations using this ultra-fascinating alternative theory of gravitation say it is sitting at the centre of the sun now? There is no way mainstream mechanics can explain how it's still on the surface with no harpoons to keep it there. The sun has plenty of gravity though.
 
Re: Phiale Probe lands on comet Comet 67P/Churyumov-Gerasimenko

Just Dryson being Dryson.

Keepers of the Flame
First time ever I've been compared to a Vestal Virgin. Got a good laugh from it.

"establishment astrophysics" (which I suppose is a code-word for "people who actually know what they're talking about")
This has been Metryq's problem from the start. He also doesn't believe in maths.

Small correction, it's Philae. Maybe someone can change the thread title, too? It's giving me convulsions every time I see it. :lol:

Here's footage from the OSIRIS camera tracking Philae as it is drifting across the surface during its several "landings"/touchdowns.

Metryq and his ilk seem to find the incompleteness of modern astrophysical science concerning, so instead of looking for ways to make it more robust, they'd just as soon throw it all out, even though they can't/won't do the real work of coming up with a sound replacement. His sort of naysaying bears no more resemblance to science than Creationists bleating about holes in the fossil record as "proof" that evolution is a sham. :lol:
 
:lol:

Thanks. It was getting difficult to do the knot on my necktie... :D

You're welcome. :)
So since you're one of those people who actually know something about this... what were your highlights of the mission? And what results are you looking forward to the most?
