How life passes from planet to planet in a solar system

I have a theory. Planets can't sustain a an orbit around the sun for eternity. Like an exibit at the planetarium that demonstrates orbit, the little metal ball eventually gets sucked into the middle of the cone. I believe that a planet will do the same and supply the sun with the materials it needs to continuesley burn for another millenium.

Now as the planet gets closer to the sun the water molecules resist the heat and turn into steam. Thus staying a certain distance away from the sun. The planet looses the H2O and sends trace amounts of lifes DNA with it.

The frozen bits of water then migrate to the next greatest gravitational force. The planet will then eventually come within an orbit that has the right temperatures to sustain life along with the water it needs to support life.

If you like this theory I'll soon be posting one on evloution look for inatalonIXLR8

While intriguing, your theory would be dispelled by a basic astronomy class.

Please explain, I am always interested in the details.

actually one of the most intriguing theory's i've ever heard, and very well explained.

i'm not sure about the planets being sucked towards the sun, maybe but i dont know enough to be sure right now.

not all plantets have water on them, some do but imm sure there are some that don't, and i think the sun's gravitational force is so great that the stream wouldn't be albe to resist it, even under a massive amount of pressure i think the gravitational force would overcome that of the gases' resistance.

i dont think we've found DNA on many planets yet, but apparently mars may have some evidence of life there once, but its not beleived there is any life there now.

i dont think that the frozen particles, would just be pulled towards the next strongest gravitational pull, if they're that close to the sun then maybe they wouldn't escape it, and with the immense amount of enery within the sun the hydrogen an oxygen may seperate, hydrogen would burn as a fuel, as would oxygen as it's required for combustion. but im not exactly sure.

if there was any DNA i think the sun's massive amount of heat would destroy it.

sorry to pick your theory apart, its certainly one of the best i've ever heard an is far more realistic than most, how did you coem up with it, i found it incredibly fascinating, and really impressive.

if i'm wrong, someone please correct me, dont take my word for the stuff here, im sure there are thigns i've got wrong.

Your points are definately valid. I'm re-evaluating my theory, but I suspect both sets of ideas come into play. The idea is 100% home grown. I sometimes can not fall asleep at night with my mind racing full of ideas. It's either that or I'm thinking of the next modification for my vehicle. Sleep is a waste of valuable time. LOL!

That is true. Anything entering such a close orbit with the sun would vaporize, destroying any life or DNA the object/planet contains, and would not escape the suns gravitational field.

The sun is expected to become a red giant in about 6 billion years. At that time, it will expand and engulf the inner planets of the solar system, including Earth.

That makes sense. I still wonder if it's at all possible for trace amounts of H2O to escape a planet's atmosphere before it enters too close of an orbit to the sun. Perhaps when polar ice is melted, small particles of water that have the right pollarity charge are able to use the north/south pole for launching into orbit.

A particle of the same pollarity will repell against the planet and shoot off into space to be caried away by solar winds. For this matter I supose it doesn't necisarily have to be H2O at all, anything heading out of orbit could carry genetic material with it.

It has become fairly common thought, that if evidence of life is found on Mars, it will most likely have come from our planet.

i have a theory on this also. Yours was very well done but i thought i would chime in and see what you guys thought.


Almost everything on our planet is cyclical right? Well i think that it wouldn't be too far out of reach for there to have been life before us. Like a massive virus or a global ice age that no humans could sustain. Almost like mother nature saving us from ourselves. Large disasters are horrible but they happen for a reason, not saying that God made the disasters happen but maybe the virus' of the world and the natural disasters are a way of moderating the human population?

And with your theory i believe it may be possible but i think that something as fragile as DNA making such a trek would be highly unlikely, also the when the DNA would get to the sun it would be destroyed because of the high heat and gravitational energy of the sun.


Awesome thread btw....

Additions to any theory are always interesting to think about. I welcome them all! Ya, I agree that some of the viruses that might be floating around in space will get sucked into the sun. I'm thinking that there would be countless numbers of them. Most would end up on a dead planet, or sucked into the greatest source of gravitational force of a solar system (the sun). But sometimes in the perfect situation they will come down on a planet with the right conditions. And it has been proven that viruses can withstand deep space temperatures. Could you think of a better way to make them last an eternity?

:screwy: Hold up. What am I talking about? I thought I was writing a reply to the -Evolution and viruses- thread. Whoops!

the only thing I didnt like about the theory is when you said that the planet will fuel the sun with material to burn.

I'm pretty sure the sun would be okay without the help of planets. And in reality, the sun would supernova before that happens, and just engulf the planets.

what I wanna know is how can they figure out that if the earth was even a couple feet further or closer to the sun... we would not exist. I think that's some BS. I saw it on the discovery channel.

very advanced math, using the gravitational pull of the sun and the momentum and mass of the earth... i wouldnt know the equation, but u might be able to find it online somewhere...

Like an exibit at the planetarium that demonstrates orbit, the little metal ball eventually gets sucked into the middle of the cone

but in space, their is no friction.. the friction from the contact of the ball and the surface and the air resistance causes the ball to lose momentum and is sucked it from the gravitational pull...

I think that the Earth is encountering friction. Small particles in space that it runs into while orbiting the sun. It may not be measurable, but given time could slow a planet down and change it's orbit.

Yea its true and its already been proven but were moving outward I think (not sure). I saw this on the discovery channel and how theres a certain distance from the sun that sustains life. In about 100k+ years will be out of that zone and a new planet will move into place. But... What about the time it takes for that other planet to get into that zone of life... Will there be no life?

dunno if it was already pointed out, because i didn't read the whole thread, but this wouldn't work because the steam would remain part of the atmosphere of the planet until it crashed into the sun, whereupon something would happen to it there. Also, when water vaporizes, it doesn't take stuff with it. everything in the water remains where the water used to be.

It is a plausable theory. I have one problem...stars rely on nuclear fusion to produce heat and energy, they don't use planets. The sun combines Hydrogen atoms and uses that energy to stay "burning." It is the same way a hydrogen bomb works to create such a massive amount of energy.

sorry, that doesnt work either... the earths gravitational pull is constantly pulling in these particles... it doesnt just "run into" them.. once they enter the gravitational pull they usually burn up before even getting close to the surface

LMAO

I read this last night when I was high and I had a closed eye visual of what this would look like in a diagram. It was nuts

I'm pretty sure our Sun won't supernova haha. It's too small. What will happen is it will turn into a Red Giant, and then shrink down into a dwarf.

Only stars with enough mass can supernova, stars that start out as Giants, and then they collapse into black holes.

Also, its not a couple of feet that we have to work with, the earth moves millions of miles in a year. But there is def a band of living that the Earth is in. However, bacteria and other single celled life can exist far outside that band, so why cant other forms of life?

The earth is very very slowly moving towards the center of the solar system and plummet into the sun. But before that will happen the sun's diameter will grow to out where the earth's orbit is, then it will reduce to a 'white dwarf' about the size of New York City, in diameter.

The pull of the Sun will pull in any debris from the Earth. The cosmic winds from the Sun do not affect us because of our ozone layer and magnetic field. So DNA particles will not 'drift into space'. Even if they did the freezing cold / intense radiation / extreme heat the DNA's structure would be too messed up to view. (Ontop of being sucked into the sun)

They say that simple organisms can sometimes bare the intesensities of extreme hot/cold. Down in the ocean there are heat vents of 140*F that house some small crustacians(sp?) and tube-plants.

As for building a long lasting sentient organism, you'll need millions of years of stability and a very low-fluctuating temperature. The earth doesn't fluctuate that much. Mercury for example goes from 700*F to -400F*. Saturn and Jupiter's core's are liquid nitrogen. (-250*F LIQUID)
