Yes, there would be - kind of like how an octopus moves.
Not much of a change though.


Maybe DrPizza can use this as a sample problem in his physics classes. :laugh:

What great timing! I just started conservation of momentum today.

It won't work. The body will absorb most of the energy imparted on it by the ejaculation.

There are no dead man's sticks in space. And no matter how stressed anyone gets, they can't even enjoy a little release by manipulating their own joystick: One of the effects of weightlessness is reduced blood flow to the lower half of your body. The rumor in Star City is that many have tried in vain to get it up out there. "There vas top-secret program of this," Driga says. "But the man could not perform. Viagra vill not help."

Russians tried, failed

I don't get it though; gravity doesn't cause erections, certainly not from standing up. "Morning wood" would not be in the vernacular otherwise.

Yes, the body will absorb the energy, and start moving as a result. In reality, internal damping effects would perhaps cancel out any acceleration that may occur - for example, model the person as a simple beam, and they may begin to vibrate at the center as a result of the force imparted by the ejaculated material. Thus there would be motion, but the person would remain stationary.

Plug that model into some FEA software, and you could run a modal analysis to determine the frequency at which the oscillations might be likely to occur, as well as where the vibration nodes would be located.

Assuming the person is a "rigid object" , then the person would begin to move.
Assume some values for the mass of the person and the mass of the ejaculate, as well as some velocities.
Calculate the momentum of the ejaculate, and you can get a force out of it, which would be imparted on the person.
F = ma
Solve for acceleration.

If you want to get really tricky about it, the spasms in an orgasm occur at approximately 0.8s intervals. Model that as a discontinuous function, and use a Fourier Transform to get an equation for the line; maybe add in some damping effects to account for the fact that the force imparted declines with each peak.
Then you can graph acceleration versus time.


See? This could turn into a problem employing some reasonably advanced calculus and sophisticated engineering software.

Yes, you went too far. The damping of the body, like both of us said in 1 sentence, would absorb the energy.

I say it would still move. Even after some of the energy was "absorbed" by being converted into heat through internal damping effects, there would still be some backward motion, though it would be slight.


"An engineer will call a horse a sphere in order to make the math easier."



Sadly, I'm finding myself tempted to set up a model in ANSYS to determine the speed.
But it'd be a pain in the ass to incorporate damped vibration effects into it, and then do another linked analysis to determine the resulting velocity.

Fortunately, I've got better things to do.

Sex in Space is the title of the next episode of The Universe on The History channel tonight at 9pm EST .

The challenges of sex in space as humans move toward colonizing the cosmos.

I can imagine a whole new porn industry

Debbie does the cosmos.

actually, I think the challenges would be much reduced.

For example: No option, really; swallow only.

NASA would be too conservative to do this.

*zzzzzzip!*

What are you doing, Dave?

*fap fap fap fap fap fap*

I can't let you do that, Dave.

*splurt!* <- right on HAL's red "eye" thing

Fuck you, Dave.

LOL

OMG :laugh:

Blood flow causes erections, in space you do not get enough blood flow to your lower body to be able to have an erection.

i'm pretty sure sex has happened in space. pregnancy in space is the real nightmare.

You wont have to catch the baby, it will just float out.

I LOLed at the 3 dolphins technique.

that was a good one . the snuggle tunnel is stupid (what's wrong with a permanently installed love nest?) and the sphere of water held in place by air vents is complete bs

honestly, what is the big deal? the couple and their ridiculous suits riding the vomit comet is worthless. is it so difficult to bolt a bed to a wall and have some handles sewn into the sheets? dumbass scientists :|

instructions for sexy astronauts:
step 1, for her: hang on to the headboard and open your legs
step 2, for him: you know what to do, big guy

Are you kidding with the number of space flights history has racked up so far and given the natural curiosity of your average astronaut I find it hard to believe not one has masturbated in space!

Remember, they almost always have biosensors on recording hearbeat, BP, etc...I'd imagine most wouldn't dare.

Right, right forgot about that.

i must admit, i would like to see what a weightless facial looks like :laugh:

Yeah, no money shot in zero g porn. Guys will have to start finishing the old fashioned way just to keep the mess contained.

why not? inertia

gravity?

At first glance I thought you said "gravy" and I was like WTF??!!

On The Universe last night, they said the exact opposite. Many astronauts have "a viagra effect", and often have painful erections for extended periods of time.

BTW- did anyone watch that last night? That goofy woman that made the coupling suit had bruises all over her face and neck after trying it out on a zero G plane lol!

Right, right forgot about that.

pretty sure only during takeoff/landing if they have suits on are they wired..or in scientific experiments.

yea i heard that on other shows as well.

and waiting for the torrent to show!
