Did you ever think *gasp* maybe you dont know everything? both of you, science narrow or religion. Get over your shit and accept you both cant prove shit.
Jee...talk about completely attacking and taking no allies, I'm sure to piss someone off lol
wow, this is totall BS, space travelling is useless as the fastest thing ever is light and yet at the same time, light slows down, as these things we see in space are really happened 300 million years ago etc . Einstein said nothing can travel faster than light, Einstein, otherwise if you disagree , your stupid or Einstein is.
@jin54363 Yes because it's specified that GoD didn't do cool things to make things, and it's also specified that god follows years exactly on our clock, because totally our realm of time is dominant to the Universe
Hey you know what, I have my doubts, what resonable man doesn't? (Seriously, theres respect for the doubt of god, those who have none either your so afraid, or your easily manipulated)
but I get that feeling once in a while, deep in my heart he is real, with some stuff I see.
it was the myan calender that said the worldwill end it 2012 but what if they ran out of supplies to make more calenders and people got the wrong message.think about that idiots
Whoever said 2012 is the ending, you are WRONG! Scientists predicted that in 2000
computers would rule the world. It didn't happen though! Just cause a old old old calender said that there's going to be a natural disaster, doesn't mean there actually isn't going to happen. : /
There are many different theories on how the universe was created but i doubt it was by some mysterious being that no one has ever laid their eyes on or spoke to, and for the computer I'm using right now it was made by HP which is completely irrelevant to the subject of this conversation. I recommend you go take some science classes pay attention and stop being an idiot.
I see imaginative minds at work. May even put Sitchin in the shade for fearsome imagery. Earth giving birth thru the Pacific Ocean's Ring of Fire? Hey, that's not allowed, I am currently based in the region.
Work your worse in some other region!
"Living planets" giving birth to smaller ones? I am more inclined to believe in the NIBIRU story. At least it is in accord with ancient legends
BS - We all know planets absorb elements and gases and then they split into two like a cell. Only living planets can do this. In 2012 the earth will give birth thru the pacific ocean's ring of fire. The new planet will displace up to half of earth's water supply. There will be a global tax on water, world wars, and many problems.
immediately yes, but there is nothing but time afterwards. And these events can fuse elements in interesting ways to bring new dynamic compositions into a changed environment, i.e new metals, gasses or even an iron core for a magnetosphere. On a smaller scale, like meteors, it can bring water and then life!
First off, explosions dont destroy anything ether; just changes its current form. Second who is claiming and explosion created anything? No serious scientist I know of.
all religion is just belief to fill the void of the unknown so it gives people to think about what they believe is out there and chose the way they want to go... well thats what i think =P.... agnostic
first of all if you read the bible everything is said was going to happen has happend like that chip it told us it was going to happen and guess what is comming out by 2017 their going to try and have everyone in th world have it
I hate all you christian fucks your so closed minded.
You think you know because someone said it was that way a couple thousand years ago. We have science now and are able to prove thing to be fact. I cant wait till christ comes back because i have a bone to pick with he/she ........ why did you make all christians so narrow minded even if the facts are right infront of your face you still choose to disbelieve.
where he is their is no past or presence and he was always their. And another reason this video is fake because scientists say that 2 things cannot explode and make something perfect so they are proving them selves wrong second if one little dimension was off the world would blow up or something if the gravity was a little off our clocks would constantly be changing and tell the wrong time
man who gives a damn about wht happened 1000s or yrs ago...is this wht nasa is spending those billions of dollars of taxpayers money on? this is bullshit in a time of fucked up economy ...nasa should be benched for a 5 yr plan...
Well, since these planets are probably 1,000's of light years away from us then the hints and lights from the explosion must have just reached us recently.
Dude it's just his opinion, he has every right to express it, GinToYura did ask the question. It may have been better to say "in my opinion.." first, but don't be so touchie, he wasn't attacking your beliefs..just expressing his own.
This is a scientific video please can you please take any fairy tales to the 2012,9/11 conspiracy theory's ,UFO Landings, and other miscellaneous bullshit to the fiction area of youtube.
To quote George Carlin: " War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed. Results like these do not belong on the resumé of a Supreme Being. This is the kind of shit youd expect from an office temp with a bad attitude."
I'll try my hardest when I join the military to cause a nuclear war killing all humanity its either that or convincing the middle eastern countries to raise their oil prices to 15$ a gallon causing countries to go poor because of the high price and they have no choice but to buy it because how will the run their countries/cities or cut off the oil route in Iraq making 50% of the worlds oil disappear making countries poor or put a certain amount of fresh water in the ocean causing climate change
Cool. I wonder what would happen if a moon deorbited into a planet, and kind of like soft landed, would it form some kind of double sphere? Maybe you could even live on it that way? lol
It wouldn't be able to 'soft land'. The more massive the bodies, the the more force in the impact due to gravity. It would only be possible if there were no gravity.
But if it's in orbit, and the orbit slowly gets shallower and shallower, wouldn't it eventually just roll over the surface of the larger body, and not really impact?
The real question is if the two bodies would stay intact as two seperate bodies once they where landed on each other, or would they disentegrate. I guess it would depend on their makeup...
It wouldn't. There is a minimum speed an object must be travelling to remain in an orbit. Think of an orbit in this way:
If you fired a cannon ball off a mountain, it will travel in a parabolic arc until it hits the ground. The more force the cannonball has, the further the distance travelled. If the cannonball had enough force, it would orbit the planet.
So if a moon were to spiral in, to remain in orbit, it's speed would need to increase, and remember; F=MA.
What's the altitude that the moon would fall from if it's orbit would be decreasing instead of expanding though? I don't think it would have enough speed or fall from a high enough altitude to create a complete devistation of the earth and the moon.
Ok, first equasion we need is Gravitational Acceleration which, for earth, gives an acceleration of 9.80 m/s^2. Then we need the mass of the moon: 7.36 × 10^22 kilograms. So we multiply Mass by Acceleration and the product is the force of a collision with the earth in Newtons. This would be 7.2128^23 or 721,280,000,000,000,000,000,000 Newtons.
To put this into perspective, Mount Everest falling from space would produce 980,000 Newtons.
I know the height it would fall from because it's falling from space. Space is about 30 miles up. The moon is falling right now. That's what an orbit is.
Objects always fall in an arc. You need to remember that the earth is constantly spinning and only appears stationary because of our relative position to the earth. If you drop an object it 'appears' to fall straight down, but we, the earth, the and the object, are all moving through space because the earth is turning. In another frame of reference (Stationary in space, looking at the earth) the weight you drop would travel in an arc.
The atmosphere does indeed slow objects down. Thats why meteors shine brightly in the night sky. Commonly known as "shooting stars'. The friction of the atmosphere along with the speed the meteor is travelling tends to burn it up in the atmosphere.
ahah copy and pasting. lol. but do you have any original thoughts of your own on this matter? do you remember what a smart man says, then play it off as your own? welll, isnt that what we all do? thats how we learn after all i suppose. but still, be original, you get pussy that way!
Alright, I get what you're trying to say that it's always falling, but the question remains at what speed it would be going when it eventually impacts the earth. I was doing some reading and it's said that likely it'd be going so fast by the time it hit the earth that it will break apart into rings before it hits. It's interesting that the tidal forces are working to speed it up right now, and eventually will work to slow it down though and crash it into the earth.
No, the moon won't crash into the earth. Tidal forces are effectively 'pushing' the moon away at a rate of 3.8cm per year. It will eventually move far enough away that earth's gravity will no longer be able to hold on to it and it will float out into space.
The moon eventually will fall back to the earth. The moon is only being propelled away from the earth because of tidal pumping beause the earth is spinning faster than the orbit of the moon. Eventually this will stabalize, and the moon will start falling back to the Earth. It won't ever get far enough away that the earth's gravity won't effect it.

What's the altitude that the moon would fall from if it's orbit would be decreasing instead of expanding though? I don't think it would have enough speed or fall from a high enough altitude to create a complete devistation of the earth and the moon.

Ok, first equasion we need is Gravitational Acceleration which, for earth, gives an acceleration of 9.80 m/s^2. Then we need the mass of the moon: 7.36 × 10^22 kilograms. So we multiply Mass by Acceleration and the product is the force of a collision with the earth in Newtons. This would be 7.2128^23 or 721,280,000,000,000,000,000,000 Newtons.
To put this into perspective, Mount Everest falling from space would produce 980,000 Newtons.

from what height? How do you know what height it would fall from?
chimera15 2 years ago
I know the height it would fall from because it's falling from space. Space is about 30 miles up. The moon is falling right now. That's what an orbit is.

space is only defined that way because of atmosphere, it has no bearing one what we're discussing.

That's an object falling straight at earth, not one that's falling in an arc....
chimera15 2 years ago
Objects always fall in an arc. You need to remember that the earth is constantly spinning and only appears stationary because of our relative position to the earth. If you drop an object it 'appears' to fall straight down, but we, the earth, the and the object, are all moving through space because the earth is turning. In another frame of reference (Stationary in space, looking at the earth) the weight you drop would travel in an arc.

The atmosphere might slow it down a bit as well.
chimera15 2 years ago
The atmosphere does indeed slow objects down. Thats why meteors shine brightly in the night sky. Commonly known as "shooting stars'. The friction of the atmosphere along with the speed the meteor is travelling tends to burn it up in the atmosphere.

I'm sure it would have a limited effect on an object the size of a moon, but it would have some.

ahah copy and pasting. lol. but do you have any original thoughts of your own on this matter? do you remember what a smart man says, then play it off as your own? welll, isnt that what we all do? thats how we learn after all i suppose. but still, be original, you get pussy that way!

Copy and pasting? No. I did the calculations myself. Where exactly did I copy and paste that information from eLLriDe420?

Alright, I get what you're trying to say that it's always falling, but the question remains at what speed it would be going when it eventually impacts the earth. I was doing some reading and it's said that likely it'd be going so fast by the time it hit the earth that it will break apart into rings before it hits. It's interesting that the tidal forces are working to speed it up right now, and eventually will work to slow it down though and crash it into the earth.
chimera15 2 years ago
No, the moon won't crash into the earth. Tidal forces are effectively 'pushing' the moon away at a rate of 3.8cm per year. It will eventually move far enough away that earth's gravity will no longer be able to hold on to it and it will float out into space.
TheFifthApes 2 years ago
The moon eventually will fall back to the earth. The moon is only being propelled away from the earth because of tidal pumping beause the earth is spinning faster than the orbit of the moon. Eventually this will stabalize, and the moon will start falling back to the Earth. It won't ever get far enough away that the earth's gravity won't effect it.

It's probable that by that time the sun will be a red giant though, but that's not really about what we're discussing.
