Interstellar travel by fungus   (+15, -2)  [vote for, against]
With enough mushroom compost, the stars could be ours.

If all the spores from a single puffball survived for two generations, the result would be a mass of fungus eight times Earth's volume. Since the largest known puffball is two metres in diameter, this means that the minimum increase in size over two years must be about seventy sextillion. During that period, an object sitting on top of the fungus would have moved a mere six thousand kilometres or so. However, project this forward another two years and it would have travelled a third of a light year. I needn't project it any more - clearly at least the whole Galaxy would be easily within our reach within six years. However, this is subjective to the surface of the fungus because clearly they would not grow faster than light, and the velocity of the growth is such that contraction in the direction of movement would soon occur.

So all we really need is enough mushroom compost and a means of hollowing out the sphere as time goes by in order to prevent it from becoming a black hole.

//So all we really need is enough mushroom compost// That would be quite a lot of compost. I foresee conservation of mass issues.

You'd need a hell of a lot of butter to cook it in as well.

There are other ways to reach far out places using fungi...
-- RayfordSteele, Sep 13 2011


Masterful halfbaking [19thly]! With this idea and the butterfly one you are becoming a chronic master-baker.

On a more serious note, I too was thinking about a form of interstellar space travel by fungi as well, and in a form you might appreciate. Well, I was acknowledging the fact that I'm sure to die one day, and was feeling a little apprehensive about it, so I decided that not enough was being done to ensure my future spontaneous recurrence. I thought then that if the theory of evolution was true in its grandest metanarrative, that complex life arises from simple life, that some simple life should be spread throughout the galaxy and beyond to increase the likelihood that complex life, but more specifically my exact self, will reoccur at some point again. Lichens or something hearty like that should do the trick.

// other ways to reach far out places using fungi //

Yes, it's called "Spaced-Out Travel". We suggest that [bungston] is ideally experienced and qualified for the test-pilot role.

Ad astra per boleto. [+]
-- mouseposture, Sep 13 2011


With these here 'ad astra' turns of phrase; am I wrong in thinking that the syntax is messed up by not putting the 'per' before the'ad'?
Just wondering.

I think I like the train of thought that must have went into this notion, and I'm fond of saying, "There was no mould to break when they made me... they barely had fungus then" so y'know that's a plus.

in math anything is possible, which is why I'm so glad I live here in reality.

Sit down, [WcW]; we're sorry but you're about to hear some really, really bad news ...
-- 8th of 7, Sep 14 2011


Math just proved that my halfbaked motor-engine is impossible because more energy is required for electrolysis than it produces.
-- rcarty, Sep 14 2011


Not an actual idea. [-]
-- Voice, Sep 15 2011


Voice, please explain yourself. This *is* an actual idea. It is an idea to travel the universe via the exponential growth of a fungus. Whether or not it is viable rests in the annotations and future scientific discovery.

Terrence McKenna would approve (linky).
-- daseva, Sep 15 2011


Excellent idea.... hovering somewhere between genius and moronic ie perfection for me! I'm awarding it the extra croissant only I get to deploy. (+ +)
-- xenzag, Sep 15 2011


As [19th]ly points out, the mass at the center would collapse -- but probably before it reached black-hole magnitude. Instead, you might get a star. Making this a Dyson sphere. But with a difference: the inhabitants can explore the Universe without ever leaving home, because home eventually encompasses the Universe.
-- mouseposture, Sep 15 2011


Hi, nice to see you're all still here - po, 2 fries, swim, 8th, Icarus, Hippo, Rayford, bungston. I have been busy teaching linguistics and falling in love, occasionally thinking about 'c' whilst fiddling with towels in my bathroom and playing with dogs. Nice to be back.
-- weedy, Sep 15 2011


but there isn't much to explore at that point: fungus ends up being everything
-- WcW, Sep 15 2011


Well, but that fungus will have evolved quite a bit, by then, what with the time dilation. Perhaps it'll be sentient. The whole (former) universe might be recreated as virtual reality within a giant fungoid brain. Or perhaps not.
-- mouseposture, Sep 16 2011


'c' = ? Children?
-- RayfordSteele, Sep 16 2011


My money is on 'cannabis' based on username and towels ie. the talking towel that asks children to smoke weed. Could be croissant.
-- rcarty, Sep 16 2011


I hope you're not talking about me. 'c' refers to the speed of light and the sort of philosophical / scientific musings that one has whilst fiddling about with domestic tasks. 'Weedy' has nothing to do with cannabis - I'm a cider man. Also, 'the talking towel'? The mind boggles.
-- weedy, Sep 16 2011


//talking towels//

I usually only let mine go until they get to the standing-up phase before I wash them. When they start developing language, culture, and religion I send them down the chute before they cast off their human oppressors. Considering the idea title though, I might just see what happens...
-- RayfordSteele, Sep 16 2011


To mouldly go where no man has gone before...
-- goff, Sep 16 2011


Does this same notion work with sperm? Or are we only talking asexual reproduction and choosing to ignore the limit imposed by the quantity of manure in the universe (as opposed to the quantity of eggs and wombs)?
-- zen_tom, Sep 16 2011


// the limit imposed by the quantity of manure in the universe //

There is no such "limit". If you have any doubts, subscribe to cable TV.

One small step for man, one giant lepiota for mankind.
-- theleopard, Sep 16 2011


The talking towel is a character from South Park. I think based on the information you provided marijuana was a good guess. Towels and dogs?
-- rcarty, Sep 16 2011


Presumably, after it gets to interstellar proportions, their won't be mushroom in the universe for anything else?
