Good Morning, My scientific friend, have you noticed Mars lately? Awfully bright.

Good Morning, My scientific friend, have you noticed Mars lately? Awfully bright.

I've been watching it the last few nights. It just makes me wish I had access to a telescope or observatory, 'cause looking at a little bright dot next to Orion just isn't all that impressive. Something needs to go supernova in M31. Not that we'd see anything now, but at least we'll be in safe watching distance.

Does M31 even exist right now? How do we know? What if the whole galaxy died 1,000 years ago, how would we know today?

Samoth's reply to you:
"Astrophysics is a very complex subject. All you novices need to know is that if you were able to jerk off at the speed of light you would be able to nut on your boyfriends chest plate before you even thought of jerking off (I would explain how this works but fuck you).

This is complicated though because the friction from your palms would surely melt your dick off. When moving at ridiculously fast speeds; time slows its self down so when I fuck your mother in space my cock bangs off her fat noodle-eating ass in slow motion. I also have more time to think about what style of punch I want to use on the back of her head when I'm about to cum. Then I would pee on her back in zero gravity and push her into the Sun. Then I will stop by Jupiter just so I can weigh my testicles and they are pushing a hot and heavy 30 pounds (If you use the metric system I'll stab you). Then I would fly around for a little while and look for some old space anus to sodomize (note; some aliens have thoraxes so instead of sodomizing them I fart in their soup then punch their larva). Then I hook up my VCR and we watch Skid Row videos in space then smoke some laser hash. Then I would come home and say someone robbed my house so I could get some insurance money then blow it all on tacos"

Interesting. Has anyone done studes on the propagation speed of gravity or lack of it? What's the speed of dark?

I thought dark was instantaneous. Let's say M31 became a singularity. The mass would still be the same and would create the same gravity well, so it would be the same from that aspect as well, correct? Or is my astrophysics so ludicrously rusty that I'm talking out my ass?

That's a good question. I'm pretty sure it doesn't have a quick, concise answer. If the whole galaxy were to suddenly vanish from existance, we wouldn't know it for a long time, lol. But the answer to this lies in the laws of physics and cosmological models. We know mostly how stars work... and how clusters work... and galaxies. Now, given this knowledge and that of gravitation, some fundamental constants, and the fact that stuff on this scale cannot happen "quickly" by human standards, there is no way for Andromeda to exist several million years ago and not exist today. In astronomical terms, a few million years ain't that long.

Very rusty, normal space is chock full of darkons, which make everything look dark. Fortunately, however, we can get rid of darkons in various ways. For example, if you are in a dark room, full of darkons, and turn on what you naively call a "light", the "light bulb" acts as a darkon absorber, sucking up the nearby darkons. Of course, as nearby darkons are absorbed, others move in to fill the gaps, leaving spaces further away.

What is the speed of dark? Well, consider how fast darkons are sucked up by any standard darkon absorber. The speed is obviously what we incorrectly refer to as the speed of light.

The theory of darkons is at this stage incomplete. After thinking through various consequences of the model, we had a few minor problems with issues such as causality. We are confident that there are ways around such problems, though a radical new physical theory may be needed.

Isn't Andromeda on a collision course with us? Hopefully, I'm still around when it happens, oughtta be fun. (I'm gonna live for quite a few millenia)

If it were reduced to a singularity then I'd assume no change in its gravity well but what if it exploded and dissipated? Maybe at this kind of range we'd still be unaffected since its center of gravity would likely be unchanged.

We'd have to have it be popped out of existence for any consideration of effect at this range then. Since we know of no way for this happen, we likely have to consider that we have no information on its last 1,000 years.

How do we devise an experiment to measure the propagation speed of gravity? Maybe if we had two synchronized clocks which are taken apart, each subjected to the same but opposite accelerations to keep them in synch. At a suitable distance the holder of one of them moves a galaxy aside at a predetermined time and the other waits to note the effects.

I think dark is merely the road on which light travels.

Do we employ Arnold Schwarzenegger to move the galaxy out of the way at the appropriate time? Or do you think he doesn't have the connective tissue flexibility to lift heavy anymore?

 

[samoth]

Oooh boy, umm, that's kinda complicated. Gravity is one of the four fundamental forces in the universe. Each of these forces is mediated by a particle. Photons are the mediating particle of the electromagnetic force, where gravitons are the particles that mediate the gravitational force. There are conflicting studies as to the "speed of gravity", but it seems to point towards instantaneous. This stuff is very theoretical and new, this would be classified under different quantum gravitational models. It's hard to say much about this without getting technical pretty quick.

Don't bother me with implementation details. that's why we have engineers.

 

[BrothaBill]

to begin to accept this radical new theory, you have to throw away your ingrained belief in these "photon" things you keep talking about. You could postulate that a "photon" is a hole in the darkon sea, but that would really just be an excuse to return to the old ways of thinking.

Oh, and I forgot to mention: There is a lot of evidence that the ancient Muppet race on Mars knew much more about darkons than we can ever hope to comprehend...

Thinking of it, admitedly hopelessly crudely, as billiard balls on a rubber table, that'd be akin to suggesting that the underlying structure would immediately and everywhere realign itself on the introduction or removal of a mass.

Depends on the scale at which one is looking at. M31 could be considered isotropic if looking at the galaxy's effect on nearby galaxies and clusters. However, it's isotropism might be questionable if examining the galaxies' effect on individual stars nearby. I don't see any big reason to not treat the galaxy as a point-mass for all practical purposes, though.

From what I recall of integrating over spheres, a long, long time ago, you can consider it as a point mass with a relevant mass of everything which is closer to the center of gravity than the observer. At this range, it's effectively a point mass whether it explodes or collapses.

 

[samoth]

I've heard that before. I don't think anyone's too worried, though , they just put it on account of the dispositive nature of two nearby masses.

 

[blut wump]

Oh, and Good Morning, everyone. By that, I mean goodbye and fare well.

 

[samoth]

How do we devise an experiment to measure the propagation speed of gravity?

The simple answer here is that we can't.

BTW, there's no such thing as "dark", just like there's no such thing as "cold".

That is a correct mathematical assumption.

its not new, there is no progation delay to gravity as there is with light, meaning the forces of gravity are faster than that of light or instantaneous, its always there, a propagation delay, like the light reaching earth taking eight minutes or so is slower than the constant pull of its gravity, the results of a PD of gravity on a space orbit would be disastrous

Credited, but there's no way to remove mass, per se. We couldn't set up an experiment with two 500kg balls and measure what happens to one when we make the other one vanish into thin air.

There are experiments out there like LIGO that attempt to measure gravitational waves but... umm, how deep into the subject do you wanna get here, lol. This is about it at this level. But no one has any definite answer. This is really stuff that's at the cutting edge of theoretical physics.

Yeah, but I was referring to observing any directional shift of stars at the edge of the 'cutoff' of the now-defunct galaxy due to the effects of gravitational anisotropy in that small part of the galaxy acting on those stars. But it'd be a small detail.

No one's sure if the exchange of gravity's force-mediating particles is instantaneous. Non-perturbative quantum gauge theories of quantum gravity are sketchy at best.
