Acceleration of expansion. Dark matter

Acceleration of expansion.

Er, this is actually required for some cyclic models. One popular theory is the ekpyrotic model.

Bokbreath 3 points

Space and time were not confined to an infinitely dense point. That’s a popular misconception. Density isn’t even a valid a concept without space. Infinities are also at odds with what we know from QM. This is where we are guessing since the theory we use to retrodict this is GR, and it is a theory of space time. We can’t expect it to tell us anything about states that do not involve spacetime.

I do believe theoretical physicist Lawrence Krauss addresses this very issue in his book, "A Universe From Nothing".

In it, he talks about how it's possible that even in the vast nothingness of a universe that has been dead for an infinite amount of years, random quantum fluctuations can give rise to another big bang.

I’ve never understood why people make that argument. It’s like saying the US should suspend all science and research till they take care of every homeless person in the country.

To be fair, we do bitch all the time about spending money on certain areas, and feel it should be allocated elsewhere. The one I see most often on reddit is the U.S military. Many on reddit would like to slash our massive military's budget and direct it to health care or education & other related projects that help out American citizens directly (opposed to spending our tax money to protect other countries).

In a similar vein, I do understand the logic behind not wanting to spend $85 million on a relatively un-exciting, mundane moon probe mission and instead re-allocating that money in one of the most populated, poverty stricken countries on the planet.

Not that I am for or against this mission, I honestly have no opinion since I'm unfamiliar with India's economic situation. Also, this probe mission doesn't have super lofty goals - I think the real question to ask is; Is what we learn, the data we acquire from this mission worth $85 million dollars to India?

It will simply be studying a few old rocks on the moon over the course of 14 days and taking a couple pictures of the Earth. If that was its only goal, then I would have to say that I don't believe it's worth the cost given the fact that the moon (relative to the other planets & moons) is a known quantity (I personally would want to spend that money on studying Titan or Europa, those are incredibly interesting to me). However, I don't think that's the probe's primary function. I think it's primary function is to see if India can do it. A test or proof of concept that will advance their own space program. In that scenario, the cost could very well be a massive bargain if it causes India to make tremendous strides in space exploration.

As someone who's dealt with both, Canada's immigration process is WAY more strict. You aren't getting in unless you have a lot of money or you're highly educated in some specific in-demand fields. It's funny that a lot of Americans found this out back around the 2016 election when they were thinking about immigrating to Canada. Turns out it's not so easy.

Does Canada have a marriage exception? Where if you marry a national, you can get citizenship? I think most countries do; I know the U.S has it, and Japan does. China doesn't, however. In fact, I think it's literally impossible to become a Chinese citizen. They've allowed either 7 people, or 7 people per year (I can't recall).

That's beyond cold, though. That's an incredibly hazardous substance. In fact, I doubt our current space suits could handle it for more than a few minutes. We'd need something more than a regular space suit.

90% of the time that word is used, a person has grossly underestimated the task.

You can probably open a cheap padlock that way but there are a bunch of tricks used on a reasonable lock that makes the task much trickier. The more you pay the more tricks there will be.

And if you protect your home and belongings with the cheapest possible lock, you deserve should expect to get things stolen!

Most property locks are not trivial to defeat, and it is much easier to just break a window or lever open a door

edit - backing off on overly dramatic language.

This is probably why it's not really cost efficient to pick up a $300 Abloy padlock to secure something that can be accessed by just removing the door itself, breaking a window, etc. They're amazing locks, but I struggle to think of a use-case for them (other than lock sport/collecting).

It can work you need a tension wrench tho

relic2279 26 points

That's the one thing they always get wrong in the movies -- using 2 lock picks to pick a lock. Where's the damn tension wrench?! And picking a lock doesn't take 6 seconds. Unless, of course, it's a Master Lock. Not kidding, you can usually just rake the thing open. BosnianBill has some hilarious youtube videos of opening them in literally seconds.

Wow, TIR.

Edit: just so that people don't think I'm just some random racist, I want to clarify that I'm Japanese. I'm so glad I moved to Canada at a young age so I can pronounce my R. I did get traded teased a little until I was fluent in English, but I can see the humor in it now. Also, another sound that we have a hard time pronouncing that maybe some of you don't know, is the "hoo" sound. We almost always say "foo". So "hoodie" will sound like "foodie" and "who" like "foo'".

Edit 2: sorry, made a typo.

relic2279 1 point

I'm so glad I moved to Canada at a young age so I can pronounce my R.

Japanese have no trouble pronouncing "R". The letter (phonetic sound) is used in their own language. Ryu, Ramen, Ron (Japanese Mahjong Term for going out on someone's discard), rounin, Raijin, etc... They have trouble with L and often pronouncing as they would an "R". This is becoming less and less of an issue though, as they adopt more foreign words (due to the internet, cultural exchange, commercialism, etc).

There's don't get "proved" in the way your title implies. In fact, theories never graduate into anything else -- they stay theories permanently. They can either get stronger as more observational evidence pours in (as is the case here), or they can be disproven.

So, my Q is related to the Fermi Paradox. Has anyone considered the idea that maybe we have been "excluded" from seeing that space is teeming with life, a la The Truman Show? Perhaps what we see when we look through our telescopes is nothing more than what we are being shown. It would kind of work with the theory that we could be living in a simulation also.

binarygamer 7 points

The issue with this theory is that there's nothing tangible we can talk about beyond saying "hmm, interesting idea". The level of control of the universe required to make this function across the entire solar system, and convincingly enough to trick all high resolution astronomical instruments and data scientists, would be ridiculous, akin to godlike status. With that kind of ability, you could propose any of thousands of possible things about the universe the galactic information police might be hiding/falsifying, and nobody here can argue for or against them in any convincing way, nor can we conceivably have any way to experimentally test the theory or estimate the probability of it being true.

I do agree the hypothesis is just a thought experiment, however, I do not think it would take very much to isolate us. Due to the inverse square law, unless an alien civilization or alien society sent an insanely powerful and focused radio/laser beam right at earth, there's no way we'd pick up stray signals from ET. Our own terrestrial TV & radio signals are indistinguishable from background noise at only a light year away from the Earth.

Another thing to consider is that radio waves work well here on earth for short distances, but at the interstellar and galactic distances, they're ridiculously inefficient. I do not believe an alien civilization (especially an advanced one) would be using something so inefficient to communicate. It's kinda like us using smoke signals. I don't think it would take much to isolate us because I don't think we're advanced enough technologically, to even detect their presence yet.

This is a well-known hypothetical called the zoo hypothesis. It postulates that we've been cut-off from the rest of the active galaxy. Either because we're supposed to develop on our own, without interference, or because we're being watched for entertainment purposes. Maybe even both. The former is something we've done here on earth, with a few isolated tribes that still live relatively un-contacted by the rest of the world.

Keep in mind that there's zero evidence for such a hypothesis so it's nothing more than a thought experiment.

I think the part that really unnerved me was a specific noise that Kayako makes as she crept on a victim. It's done using the back of the throat and awakens some weird primal fear in me.

It sounds a little silly in hindsight now, but in theaters...with surround sound and a very loud volume as a teen....brrr.

I also think that an element that adds to the horror for us westerners is the stark difference in culture and setting -- they're unknown quantities to us, something we're not really familiar with so that helps add to the uneasiness and alienation. It helps to take you out of your comfort zone, even if you're sitting on your couch at home.

I love Japanese horror for this very reason - they have a lot of urban legends and myths that are completely unknown to me but make for refreshingly new & uniquely horrifying movies. Like the slit-mouthed woman. "Am I beautiful?". Don't expect big budget affairs, however. Japan's film industry isn't nearly as large as Hollywood. Though, that does afford them the ability to take more risks on stories/plots which can lead to surprisingly good movies many times. Admittedly, this isn't always the case as there are some stinkers too.

Non-technical question: does anyone know anything more about why Jeanette Epps has been grounded? There's some speculation on Twitter, which led me to wonder if having "CIA" on her resume might have been seen as an undesirable thing for an international space station. But that's a wild guess. Anyone have the inside scoop?

relic2279 1 point

I honestly think it may have been "personal matters" and has nothing to do with her previous CIA work.

There was an astronaut a few years back (Lisa Nowak) where she was arrested on attempted kidnapping charges and was clearly mentally unstable. They may have become more strict about personal life issues so something like that doesn't happen again. I think part of the job entails being a role model and if they deviate from that (getting busted in a bar parking lot snorting coke or something) they probably have zero tolerance for it.

Is there one stand out solution to nuclear waste disposal that involves dumping said waste on a moon or planet, ejecting it in to space, or in to the sun? Or would the attempt to get it out in space be too dangerous to consider this as a possible option?

In addition to the safety issues, it's ridiculously cost prohibitive. I don't think people realize just how expensive it would be to send a few tons of spent fuel rods into the sun (using current technology).

How do the antennas on space probes work when some of them are near the edge of the solar system? Is there a point where they're large enough that distance won't affect them too badly?

relic2279 1 point

It's less about the antenna size at those distances, and more about how much power is required to send the commands. The more juice we use, the further we can broadcast effectively. Our broadcasts are made with pin-point precision so it's really all about the wattage of the signal to keep it from degrading (inverse square law).

thereisnocenter 1 point

Power isn't everything if you can make higher and higher directivity antennas. New Horizon's has only a 12W transmitter.

relic2279 1 point

On New Horizon's end, the transmitter doesn't have to be super strong since it talks to the deep space network. We can use our massive dishes and arrays to pick up the faintest of signals.

For a long time, we thought they were pretty boring planets compared to Jupiter and Saturn, so we couldn't really drum up support for funding for missions to the ice giants. And that's really what it boils down too; precedence of funding, where can we get the most bang for out buck.

Fortunately, we've found out that the ice giants aren't quite as boring as we once thought so missions may materialize.

I'm 38 -- only true geeks and nerds (super early adopters) did the whole BBS thing. I was one of them. People logging onto our local BBSs were people that were into ham radios and so-forth. The internet didn't really expand into normal people's homes until 2000+

Remember the dotcom bubble of the 90s? That's because people were using the internet en mass by then.

relic2279 1 point

Not at all. The internet was still 'new', that's when adoption began to exponentially increase, but it wasn't in full swing yet. That's what caused the bubble; people were beginning to use this new fangled thing, and everyone wanted to get in early. Money poured in but there wasn't enough traffic (cashflow) yet to sustain that kind of growth.

This graphic shows that the internet didn't really "grow" until after the dot-com boom which went bust:

Also, in 1997, the total global internet traffic was 100 GB per hour. In 2002, 100 GB per second and by 2007, it was 2000 GB per second. Source The internet wasn't really adopted by the masses until after 2000.

I've permanently banned less people in my 10 years on reddit (modding a few of its largest subreddits) than I have fingers. I don't do it because it doesn't work -- Perm-bans don't work for the reasons you state. And hunting down a persons new alt is nigh impossible so any rules which forbid creating a new account to evade a ban are wholly ineffective.

Temporary bans, however, do work somewhat. They work to moderate a person's behavior. Like a slap on the hand.

But sometimes a person is so determined to ruin a community that you need to take more effective measures. This is why I believe IP bans need to be instituted. I've been discussing & thinking about them for nearly a decade and have considered every drawback. Including inadvertently banning an IP for an entire dormitory, business, etc. Also, people can use VPNs to circumvent the bans, but I think the net benefit is still outweighs the drawbacks - it's better than having someone ruining my community. Especially a small community that's struggling. in extreme cases where your ban cuts of access to a country or something, that's when you can have the admins step in and do a meta-data ban or whatever they call it.

EDIT: WTF, why did the mods flair this as an Ad? He clearly says he's not affiliated with Amazon.

Mod here. I wasn't the one who flagged it. However, with the way ads can be obfuscated nowadays, better safe than sorry. Intentional ad or not, it still sets out to promote a product. I personally don't care whether amazon paid for it, someone/company did it freelance, or Amazon has zero affiliation with the video, the end-result is the same.

Also, him saying he's not affiliated with Amazon almost makes me laugh. I've been doing this a long, long time. People looking to strike it rich on youtube will literally (not figuratively) say and do anything to get a hot viral video, using every dirty trick, spam technique or technicality that exists in the book. A lot of the shit I've seen people pull over the years is borderline unbelievable, some of it is truly ingenious, some go to such great lengths that there should be some sort of awards given out yearly for their efforts.

Ninja edit just to be more clear: Amazon could have hired a third party company to do the ad work, then that company could have subcontracted out the video work to this guy (could be a freelancer that does occasional work for the company). That would mean he's technically not affiliated with Amazon, despite Amazon paying for the ad. I'm not suggesting this is what's happening because I haven't bothered to look into it, but I am using it as an example to show just how convoluted these things can get -- in truth, that's pretty mild compared to some of the crap we see getting pulled from time to time.

I'm having a hard time discerning what's what in that photo (my eyes aren't the best these days) Is that earth in the center there, with a little crescent or sliver of light? Because if so, that's not taken by an astronaut. The earth is too small in the photo. That photo would have to be taken at a distance way past the moon for the earth to appear that small.

Just a PSA: Please don't play on the escalators folks. I've witnessed so many accidents happen on them (around 1 every other week, sometimes more. 2 have resulted in deaths [granted, they were very old people so not in the best shape]). They're not made to be walked up or down contrary to Mitch Hedberg's comedy. They're extremely sharp on the edges, and extremely slippery, so falling is much easier, and cutting your head open on them is a very real possibility. The distance between steps isn't quite the same either, so it's easy to misjudge, especially when you're relying on muscle memory to run up them.

So yeah, believe it or not, they do not become stairs when they're broke. And don't trust them. They have sensors to keep the thing from running if you get caught but do you want to trust it? Trust the repair guy who has been to that location hundreds of times didn't just bypass it at some point? That exact situation happened to a Chinese woman who was literally 'eaten' slowly by the escalator. She had her kid in her arms and handed him off before sucumming to the hungry escalator. I'm sure you can find the video on liveleak or something if you're in a morbid mood.

TL;DR Do not play on escalators. You will get hurt. That I can promise you.
