It was late august and the skies were perfect out in the cornfields of Nebraska,
It was the darkest I've ever seen, I couldn't see my hand in front of me, let alone the stalks.

After about half an hour of stumbling through the field trying to find my spot, (a clearing that my friend used to grow weed) I finally stumbled upon a small trail that led to the clearing.

In the clearing there was a trailer, a lawnchair, a cooler and a telescope. I turned on my lantern and went into the trailer. There were stalks of weed hanging on clotheslines as well as a few pills scattered on a table with a note that said "help yourself", with a winky face alongside a condom.

I thought it was a prank, but I thought I might as well so I took the pills all at once and shaved off a nug branch of uncured weed and smoked it the best I could. Anyway I got out my telescope and used my night-sky app on my phone to find the planets (yeah I know, I'm lazy).

As I was focusing in on Saturn I noticed my vision started to blur a bit. I thought at first the lense was just out of focus but I soon found that something was happening. I continued my search anyway, the best I could until I could no longer keep up.

I decided to just chill on a tarp and watch the stars instead, see If I could make out the ISS and other satellites. I started thinking about how those stars are actually clusters of galaxies that are probably gone, it made me sad but then I felt something.

My dick was hard as a rock., On top of that the stars wouldn't stay still. It was bothering the fuck out of me until it didn't. I started to see my own constellations, they turned into titties and even full on line-porn.

Black holes don't suck. They have the same gravitational attraction as anything with the same mass. They just pack that mass in a small enough volume that internal gravity overcomes all the other forces.

As for particles, I don't get what you're asking, man.

You're reaching into subject matter that I think you probably need more reference knowledge for to be able to integrate fully. Probably best to just not worry about such things in that case.
But, the idea that there could be microscopic black holes capable of passing through the earth is just from one study by one physicist, as a way to explain something that probably has a much simpler explanation i.e. the LHC doesn't generate micro black holes simply because the LHC isn't capable of generating micro black holes . The accepted explanation concerning black holes in the standard model is that they continually lose mass due to Hawking radiation, and thus eventually evaporate completely, so by most physicists estimation, long lived subatomic scale black holes don't exist.

If there were a black hole in the center of the earth, then the center of the earth would fall into its event horizon, which would subsequently expand. In short order, the entire earth would be within the black hole. Anything that comes into physical contact with the event horizon becomes a part of the black hole, and since the center of the earth is completely pressurized with no vacuous space, it would consume the earth more or less instantaneously from our perspective, from the inside out.

The amount of the mass that subatomic particles, that could pass through such an object that weren't already part of the earth's mass -- like neutrinos burrowing through from the sun, would contribute to the total mass of an earth-consuming black hole would be vanishingly negligible, more or less equivalent to the number of neutrinos that pass through the earth during the time it took the black hole to consume it, (which would again, would on the order of seconds, perhaps minutes) pico grams of substance compared to the earth's 5x10^24 Kgs.

i understand the weight involved but their are multiple ways to accomplish this

(also i may be missing information on certain things)

with the miscellaneous equipment that is obsolete or ... take an electromagnet to swoop the pieces and clean the atmosphere.. *(my mind was on this)

secondly i think that while it may be applicable to take a large hook and anchor to something to even make some kind of "elevator" - to utilize this to even lift some military equipment - prefabricated buildings... almost anything

a tank is something that came to mind... a submarine would almost work also.. in zero gravity

plus with that.. it comes to understand the problems with entanglement... but also to cheaply move things from station to station on a rope ... much information should be held... but again i don't know who reads these forums

but why not

Actually firearms and cannons would work in space as they already contain all the oxidizer necessary to function. Gunpowder in all forms is a propellant with fuel and oxidizer already in supply. Firearms, cannons, turrets etc are all pressure sealed during firing which means there wouldn't be air in them anyways here on Earth.

HOLY SHIIIIIIIIIIIIIIIIIII

So apparently after decades of people trying to debunk it and call it pseudoscience, NASA has confirmed the Shawyer EM Drive actually works, producing thrust via microwaves using no propellant, apparently violating the principle of equal and opposite reaction:
http://www.sciencealert.com/it-s-official-nasa-s-peer-reviewed-em-drive-paper-has-finally-been-published

The authors suggest that perhaps the long-dead pilot-wave/Bohmian interpretation of Quantum Mechanics is now a contender again thanks to this new evidence. The microwaves 'push off' of the quantum vacuum, preserving Newton. But if pilot-wave is the true QM, that means not only that alternate realities exist, but that we see them as real effects in our world! (i.e. in the generation of interference patterns in the double-slit experiment. But surely this is but the most minor influence this generates, and probably only the easiest to notice, since in Bohmian mechanics the wave function that governs any given particle system spans the entire universe.)

NASA's totally unoptimized EM drive could get us to Mars in a tithe of the time of even Musk's proposal, with a ship a fraction of the mass ('cause no propellant.) It's bottle popping time /sagan/!

No, that would be the Xi'an team lead by Juan Yang who actually conducted experiments and published their research. And no, Chen Yue's team has not successfully tested the EM drive in space. Right now his only verifiable success is getting a couple of patents approved (which isn't a very radical development, as cold fusion was patented both in the US and Europe). There's also a Chinese state media press release about building a test device that could in the future be tested in space. Let's talk more about how successful or not the tests were if and when the results of the alleged experiment are published.

Feel free to read the press release yourself. There's been a lot of dodgy science journalism and wild claims in the blogosphere about this lately.

And of course every nation would put it on their satellites if it works - this shit would revolutionize space propulsion, provide free energy to Mankind, and allow us to conquer the stars. But all extraordinary claims require extraordinary evidence. Right now the "best" evidence for the EM drive is shit like this >>56712

So if new space is created every now and then at greater speed and making them galaxies recede and shift to the reddest part of the spectrum, how much time until we're converted into a gaseous fading cosmic entity? How do we even perceive space? How would we perceive space expanding when it eventually gets fast enough to notice?

Everything about the rip scenario is dependent on the nature of dark matter/energy. Specifically the ratio between its density and pressure, which may be positive or negative, or even zero (in the case where it turns out the dark substances aren't real.) The only real way we can differentiate between these cases is by getting actual observational evidence on this characteristic of the dark substances.

But it's power isn't limitless. Consider that the reach of the power of the sun's gravity is much stronger than the earth's, but because you are much closer to the earth, the sun's gravity doesn't pull you into it (well, it does in that it keeps the earth in orbit, but you see my point, that just because a force extends infinitely doesn't mean it isn't weaker at any given place than some other force.)

There's 10 times more matter in the universe than we thought:
http://blogs.discovermagazine.com/d-brief/2016/10/13/the-universe-is-20-times-more-vast-than-we-thought/#.WCLTmjU2thE

A natural law for rotating galaxies:
http://www.physicscentral.com/buzz/blog/index.cfm?postid=5308541299875990673

And finally, matter causes entropy displacement which accounts for the dark matter effect:
https://arxiv.org/abs/1611.02269

TL;DR, we found our missing mass, we can see that rotation speed varies with the amount of visible matter, and with a better understanding of gravity, the whole concept and purpose of dark matter is bunk.

>Yo, I agree with most of what you've said man but...
Yeah, I was mad in that last part, excuse the flippancy. You raise a valid point about the snapshots-in-time. The only caveat is that we can observe [usually] the same type of effect in several locations in the sky. This can give us a good correlation to the observed effect being distributed evenly in the universe.


It is my sincere wish, however, that we stop poking logic holes in each others' theories [see >>56645 and >>56748 ], and start referencing actual science articles to back up assertions. OP did a good job supplying articles to chew on, followed by good counterpoints by others. Lets get more of that.

Well I wouldn't call it a snapshot in time, but rather a snapshot in perception. Our view of the universe is always changing, so the picture we have right now is only a snapshot, regardless of how much time it represents. You can say the current laws of physics are immutable and timeless, but these laws have only been accepted as a general concept of the universe for a couple hundred years. Previous theories of the universe such as Platonic Idealism were also based on observation, and were of course supposed to be immutable. They lasted for thousands of years.

If a0 is equal to the speed of light divided by the radius of the universe, since the radius of the universe is equivalent to the time since the big bang and thus always increasing, presumably this also means the acceleration constant decreases overtime, which means the same amount of force creates more acceleration, right? (thus accelerating expansion) is this an intentional aspect of MOND? Why didn't they predict an accelerating universe beforehand if so?

Wrote a big response but the board swallowed it twice. Milgrom is talking shit, MOND doesn't bridge anything with the largest scales. It fails if you look at anything beyond galaxies. Galaxy clusters, Milgrom admits you need dark matter. Standard cosmology needs dark matter for structure formation but MOND doesn't do structure formation correctly at all, the extra gravity fucks things up. Lastly there is no MOND cosmology, previous attempts to predict the cosmic microwave background were abandoned after they became incompatible with the observations. The only thing MOND does well is galaxies which it was designed to do, it was a model to fit the data, not derived.

Lastly the radius of the universe is a number derived from cosmology, if you change the cosmology to MOND it's not the same. The point about a_0 makes no sense.

MOND makes gravity stronger on large scales so that would increase the pull of gravity between galaxies, increasing the deceleration. MOND doesn't have a cosmology so it can't really make these predictions.
