What do they grow with? They have the energy to grow at the start, but once the reserves of energy have gone, where does the seed get the energy to grow?

like seed of plant takes energy from soil and growing till its age complete like this system seed of our planet is taking energy from universe it self and growing day by day.

They why are there different size planets? or are there different species of planets? or "more fertile" areas of the universe where planets grow larger? or turn into stars.

Are you suggesting that the world is getting bigger? Or growing as a plant would or is this another branch of the Gaia hypothesis?

All I know is I don't want to be around when the planets start mating! Or the inter-stellar bumblebees come a calling!

For slightly more serious questioning please see below:
Why don't these seeds (apparently on our planet now) start hatching/growing at the moment?
How come all these 'seeds' orbit a star?
How come they orbit at all - where does the angular momentum come from?
Who/what planted them?
Where did the first seed come from?
What do stars grow from?
What are asteroids/comets? Seeds that failed to germinate?
How come all the stars/seed systems are moving away from each other (red shift)?

and most importantly...

What evidence do you have for this theory?

Oh yes, and are there any intersteller weeds? Or invasive plants (like Japanese Knotweed)?

Even worse, a planetary sized Venus fly trap!!

Ahhh...actually the clue's in the name! Never spotted that before

Venus fly trap = black holes!

Yep and humans are green fly too!!!!!!!!!!!

Do planets evolve? Have planets become more complex since the big bang?

I think it depends on what you mean by "evolve." Certainly our crust has become more complex since the beginning of earth when plate tectonics had not started or was just getting its start.

If you're meaning something like becoming more advanced (likened to learned and increased technology in humans), I don't think so. Planetary composition is controlled by the elements at their disposal upon time of creation.

However I think there may be a greater abundance of heavier elements due to star creation/destruction, but they may be getting spread out in the universe at about the same rate the universe is expanding (if that hypothesis is true), making relative abundance not much different. so MAYBE planets are becoming heavier with more higher-numbered elements?

but who knows? I don't anyways. maybe some of you do.

it is true that our planet is growing day by day but very very slow because its age is very long so we can not feel in our short age.
earth is living thing like plants and its birth in universe is like same a plant in forest.

I'm not sure what you mean by "growing"? Do you mean the changing configuration of the plates? We can actually observe that now: GPS can show the plates moving: just takes a few years to see a few mm's

I had heard that the planet was getting heavier by about 3000 tonnes per week or something. its due to space dust and small rocks falling into our atmosphere. it must add up somewhere, or can the earth lose wieght?

Do you have a single shred of evidence for this, Suresh?

This is one of those theories that we cannot prove yet, but we might be able to in the future. Like some of Einstiens theories.
Just go with the flow...

I hate to be the one to stamp on a forum but I'm still waiting to see a shred of evidence to even suggest where the hypothesis came from - my personal guess is either too much absinthe or a touch of waccy baccy

Actually, with respect to the earth growing I feel I could argue that it is shrinking! Plate tectonics is powered by the heat generated by radioactive decay. The amount of heat produced decreases as time goes on (half lives and all that!) with less heat being produced the mantle temperature will drop and the lithosphere and plates will thicken. As we all know the volume of a given mass decreases with decreasing temperature (ignoring water for now). Therefore as the earth ages, it cools and shrinks.

Thank you and goodnight! 8)

PS: Anyone care to do the calcs of the relative effects of cooling and accretion of space debris? Could be a paper in it somwhere.

You mean you haven't heard of the expanding Earth theory
http://eearthk.com/Expand.html?

It does kind of read like a 'creationist' website.

i.e. what is accepted by all is wrong. What we know is correct. We will only show evidence that appears to support out view. We will ignore anything which doesn't fit neatly with our theory.

there are two system of birth of anyone.
1. birth from female by mating
2. germination of seed in soil
so like second system our planet earth got birth germinating in universe here universe is soil of seed of planet and our planet is growing.

like skin of euclyptus tree that is seprating from its log and new ones is coming after when old or obslete skin seprated. same way when land or obslete skin of earth seprated from globe completely new skin or new land will come. this process is going on and earth is becoming bigger and bigger upto death.
i mean land or obslete skin of earth will be seprated one day and new skin will some rise.

Nah, planets obviously reproduce by mitosis.

clearly. I thought that was common knowledge.

that seems like a lot, but I can't prove otherwise. Doesn't the earth lose some mass due to hydrogen and maybe other gases escaping the atmosphere?

I dont know. Saw it somewhere, probably a book. will try and find it. Kind of odd to think that it is happenng. 3000 tonnes just like that. But the Earth weighs so much, (and is growing ) that 3000 tonnes is nothing.

According to the Meteorites Book (A Petrologic, Chemical and Isotopic Synthesis)
Cambridge Planetary Science (No. 2)
Robert Hutchison
Natural History Museum, London
http://www.cambridge.org/catalogue/catalogue.asp?isbn=0521470102&ss=exc
it is 10,000–100,000 tonnes/yr

I stand corrected!
By the way, how do you explain the sheild areas with rock that is billions of years old, like those in austrailia?

http://en.wikipedia.org/wiki/Panspermia

so we are all aliens! but i suppose so is everything else that is living on the planet.

So just how close are the views of Scientologists and Panspermia?

If it'll get me a date with Katie Holmes/Cruise then count me in!
