Deep impact?

Does someone with a scientific background understand better what's going on? Why are the Americans attacking a comet??

Because the comet is basically a still image of what everything was at
the creation of the universe. From what I know, their goal is to
collect bits from the inside, so they can understand what happened at
the beginning of the universe.

There looking at the building blocks of our universe.

I was reading the yahoo news and some Russian woman is sueing Nasa for
several millions dollars because she said they messed up her horoscope
when the crashed into the meteor.

yeah, that will hold up...

I think if we flogged more people for doing dumb things, there would be alot more floggins.

I like the fact that they blasted millions of dollars of tax payers
money off into space essentially to whack a big rock to see if it
splashed (ice) or crashed (metal/rock). It woulda been funny if it
knocked it on to a collision course with earth...maybe thats why that
Russian idiot was so pissed; previously her horoscope predicted good
fortune and that shed meet a tall dark stranger. Now it say "you will
be smashed to bits by a giant rock".

It's a comet, not a meteor :razz:

Wise words, Dr. Glass.

The projectile that was shot towards the comet has the mass ratio
comparable to that of a fly hitting a commercial passenger jet.

Unless you think the fly can knock off a plane from the sky, you shouldn't worry about the comet being affected by the impact.

Huh what do you mean by the creation of the universe? The astroids
where formed during the creaton of the solar system (but what the hell
both time points where a-freaking-way-back however one didn't explode,
and one time point existed at the same time as time)

God got tired waiting all sunday for the world to compile and finaly had it.
On the Eight day, god created func_details, and he saw that it was fast.

I think comits are a diffrent story, they are massive frozen hunks of matter that orbit the sun. Not sure about the whole "around from the start or the universe" thing, but it could well be.

Yeah, I'm not sure, I just read it in an article somewhere.

yeah we spotted Bin Laden hiding in a cave on the thing.. and we decided to take his ass out once and for all.

No really, they want to drill it for minierals, to see if there are unknown particles we have never seen in it.. Also it was a test to see if the big one should head at us, if we could stop it. Thats what they were saying on the news the other nite.

On the comet subject: They were hitting the comet so they could break
off a few pieces and study it, see where it came from. Thats the story
that they told everyone.

Here comes a End of the world Senario:

The comet was on a collision path with the earth already, They collided
the probe with the comet so it would change its trajectory. The reason
why they didn't say that the comet was going to collide was for fear of
mass wide panic: roits in the streets, stock market crashing, roads
blocked by people "trying" to get away from the point of impact,
Michael Jackson leaving children alone (Just kidding :razz: ). I know that
Satchmo's analogy is correct (inertia on earth is the same in space),
but the littlest force might just knock it out of line, dunno really.
This is of coarse a "EOTW" senario, and it is highly unlikely.

Posting And You

You know, I could be an ass and calculate it all out, but it's easier to say that the comit wouldn't effect the Earth's orbit without proof. Just take my word on it. If something did hit, it'd have to be pretty massive to actually cause a dent in our way of life. A comit the size of a state or country would do that, could cause a nuclear winter even. (the impact creates dust clouds which cycle up in the air and obstruct sun flow, this, if I'm not mistaken, in bad cases, lasts thousands of years, if not more)

The Earth's orbit changes all the time anyway, just to let you know. It's small changes, but it changes nonetheless. I think there's some other thing like, the poles switching position, that'd cause more worry then a comit wiping out life. Even if there was a huge world annihilating comit that killed the dinosaurs, it didn't kill everything, since there's still life that is similiar to what we've found in fossils.

But, I could be wrong, I mean, no one actually knows, it's all just hypothesis'.

Blame it on Microsoft, God does.

ahem

it was "beginnings of the solar system" not the universe...

It hit the commet, and then they sudy the debris

Its time was not coincidental though, NASA is a us government agency after all :razz:

I agree, I was just bringing attention to the fact that: what if a
comet was on its way? would the government tell us (to prevent mass
histeria/riots/etc.)? Would we find out at the time of impact? Really
at our level of technology there is nothing we can do to prevent a
comet, or meteor, except hide under ground and wait out the winter that
comes with these events :razz:

And yes about every 3-4 million (or billion) years the earth's magnetic
poles switch (bad for our computer/electronically dependent society),
and even the sun will eventually colapse into a black hole (or would
someone like to enlighten me as to what is does become?). Although I
doubt any humans will be around to witness any of these things take
place.

Our sun won't become a black hole, it's too small. And it takes millions of years to happen.

It goes to a Red Dwarf and increases in size (forget the ratio), I think, it's outer edge would reach Mars or something as such (destroying all in it's way, making the next closest planet very hot). Then it'd collapse back down, but it'd become a quasar or white dwarf or whatever, because it isn't massive enough.

Humans will be long dead before this happens. It'd take something like 4x our current existence time or something.

And we don't know for a fact that there are black holes, I mean, after all you can't see them, no light escapes. There's just massive "holes" in space with a center of gravity, since there are moons and planets orbiting. And yes, IF our sun became a black hole, the solar system would continue to orbit and wouldn't get sucked in.

If there were a comet heading towards earth that'd be classified as an "annihilator" or something like that, they'd inform us. Honestly, you'd be able to see it at night with university telescopes, the information would be everywhere. I think, if I'm not mistaken, astronomy students do make most sightings anyway. I'm sure, they'd try to keep it under wraps to an extent, but, seriously, it'd be like trying to cover up a hurricane, I don't think it'd happen. Not to mention, you're only accounting for the US. Other countries would have a say, this would be a global issue.

I'm not sure how they'd stop it though. The asteroid field outside Mars is doing a pretty good job so far ... which is odd, because it's just on one plane.
There are ways to advert it though. If the fate of EARTH was in the balance, I'm sure money would seem less important in this light. I would hope that all countries would participate in the funding, or that the materials and labor could be volunteered.

Realistically, if a meteor or comet came to impact with us, it probably wouldn't do that severe of damage (relatively speaking). It'd probably just destroy some cities and cause a large tsunami.

But I'm not versed in the field or anything.

Blame it on Microsoft, God does.

By definition, meteors do not hit Earth. As soon as they do, they become meteorites.

The damage a comet impact would do depends on where it hits... in the ocean, it would cause a gigantic tsunami. On land, it would cause earthquakes, and send up tons of dust. Depending on the size of the comet, a land impact could cause less damage than an ocean impact. If the comet is large, either way we're screwed.

Chrono is basically correct, even if he got the names wrong

Red Giant, not Dwarf :razz:

Some Science Site said:
In about 5 billion years, the hydrogen in the center of the Sun
will start to run out. The helium will get squeezed. This will
speed up the hydrogen burning. Our star will slowly puff into a red giant. It will eat all of the inner planets, even the Earth.

As the helium gets squeezed, it will soon get hot enough to burn into
carbon. At the same time, the carbon can also join helium to form oxygen.
The Sun is not very big compared to some stars. It will never get hot
enough in the center to burn carbon and oxygen. These elements will
collect in the center of the star. Later it will shed most of its outer
layers, creating a planetary nebula, and reveal a hot white dwarf star.

Nearly 99 percent of all stars in the galaxy will end their lives as white
dwarfs. By studying the stars that have already changed, we can learn
about the fate of our own Sun.

Eventually The White dwarf will burn out and it will become a black dwarf.

Signature? What signature!?

Does the gravity stops excisting then? Or does that continue to be at the spot of the black dwarf.

So, flogging someone "promotes" dumb actions?

You'd think it would work the other way around. :/

The best things in life, aren't things.

Gravity is proportional to mass, as the sun dies it sheds most of its helium/hydrogen, and hence loses mass. Dwarf stars are high-density (if memory serves) but not as high as say a neutron star, or a black hole. In short, there is still gravity, but not as much as before the sun died.

oh, btw, you can see black holes, in fact, they emit several kinds of light...

I hesitate commenting in this thread cause I deservedly have a reputation for being functionally stupid.. But.

I know quite a bit about this topic (gleaned from several dozen books on the subject, not from school courses) and must resist the urge to post because it would lead to a pages long discussion. However, you cannot see black holes. You can see the distortion edge caused by the event horizon, but the hole itself is exactly that.. BLACK, hence.. Invisible.

As I said, I do know quite a bit but... I just know that someone with more schooling would attempt to disprove that so I will avoid further commenting.

I just couldn't ignore the seeing comment. :rolleyes:

The best things in life, aren't things.

Acuatly, I was reading an article (can remember where it is) that said
that scientists can detect black holes from the xrays that come out of
them. Also, in Scientific American, there was an article on how
black holes may not distroy the matter that comes into them, they just
convert it. Anyway, I agree with Orph, I really don't feel like
reading a several pages long discussion about something that is
slightly off topic.

Goes up to top and refreshes memory about what the topic is about

Ah, yes, nasa shooting comets...

Until Later...

Actually the X-rays are emitted from the accretion disc as is "screams" before it is consumed by the black hole

If I wasn't bone tired, I'd look up specifics

---

Signature? What signature!?

From what I know about the x-ray emission, its emitted whenever matter enters the hole. Which I think implies mass->energy conversion, which is matter annihilation. Its impossible to "destroy" matter, but you can convert it to energy, and you can convert energy to matter.

Why not create another thread then? To me its been along time since any
actual scientific/"enlightenment" threads have been posted in the
general board.

Who knows though, maybe thats just asking for trouble to have a discussion on black holes and the Creation of the Universe.

Whats going on? I haven't heard about this?!

-[Better to be Honest than Kind]-

The problem with intellectual threads is the majority of our most learned members tend to avoid them.. Thats not to say they are rude or snobbish but the opinions I really want to hear are from members whom either no longer post, or are MIA now..

I do not see however how black holes and creationism can be compared or even intermingled within a same topic without the thread going seriously astray.

My concerns about commenting are not that I will be told I am wrong. Lord knows I am told that all to often already. My concern is that even though I do know a lot about the topic, I will not be able to convey it in such a manner that will sound credible...

Astronomy was a passion of mine once upon a time. I know damned little after 1980, but prior?? thats another story.. Problem is, current knowledge may now disprove some of my old news.

Another passion of mine was Paleontology and its related subjects.. So the planet killer comets is among that as well.

shrugs

Either way, I am off tomorrow for Connecticut.. So I will not be in any topics soon.

if the passenger jet was in space and the fly was traveliing at serval thousands of miles per hour it could either cause a slight change in trajectory (that over the distance a comet flies would acutally be a big change) or cause a considerable hole in the plane. ever hear about that fleck of dust that caused a worryingly sized crater in a space shuttle cause it was going so fast?

if a large comet or asteroid hit the water all of the coast almost everywehre would be annhilated. if it hit the land it would kick up a worldwide dust cloud that would effectively block out the sun and last for many many years.

according to one of einsteins lesser known assumpitions black holes are acutally holes in time and space. he saiid that large objects such as the sun or a planet distort space so creating gravity. a black hole is formed when the gravity becomes so intense it effectively breaks through the plane of reality leaving a hole

i realy think this should become a scientific discussion we need more of them around here
