Comment Re:Matter, anti-matter... (Score 1) 393

One possibility I have been wondering about is that of antimatter galaxies. Seen from a distance, wouldn't an antimatter galaxy look exactly like one made of matter? I have been told this is not a possibility either, since that would imply that somewhere there would have to be a boundary between matter and antimatter, where a lot of annihilation would be going on and producing gamma-radiation, which we have not observed.

I believe the explanation comes before that. During the primordial nucleosynthesis when matter and anti-matter were being created, they would be so well mixed that it would be impossible for galaxies to form. For any clumps of matter to form, the universe would have to be much less dense than it is now, and those clumps would not nearly be in the size of galaxies.

The robot missions are limited to using the equipment that they've taken with them. Woudn't a human mission have exactly the same limitation? There's a limit to what you can achieve with a pickaxe and a screwdriver. Anyway, I expect that a human mission would be so tied up in just keeping the humans alive, that they'd have little time or resources for any actual research.

Realisitically, a manned mission to Mars would be long term and pretty much have to include a machine shop and ability to repair like any large ship. Add in that there are skilled people present and if mission criteria changed due to what was learned, they could probably alter or build lab equipment for those new criteria. We wouldn't be sending just tools, but a lab with tools that could be used and arranged in various ways as needed. Which, yes, the complexity of sending such and keeping people alive reliably enough to do research is why nobody is trying to send people to Mars any time soon but rather continuing to do the research are are doing with space launches and the ISS.

Apollo 11 happened within a single decade, this time we'd be starting with a lot stronger infrastructure and tools, all it really takes is the devotion of resources.

The fuel to power the air conditioning for U.S. troops in GWII was consuming more money, annually, than NASA's entire budget. All it takes to do a thing like a manned moon landing or Mars mission is the political will to do it.

And going to Mars is a mission that is an order of magnitude larger than going to the Moon. It took a decade to go to the moon, so we can expect a hunderd years to go to Mars even with political will and funding. 40 years past and 60 years to go sounds about right. It's not like we've stopped going that way and are probably farther along that most people think. We're still sending things to space, sending missions to Mars, have the ISS doing research, all while tech is increasing on the surface. Sure, we could be doing more, but I don't think people understand the difficulty of what they mean when they say "go to Mars". We are looking at a multi-year mission for a sizable group of people in space and without any unplanned emergency backup in much harsher conditions than LEO. The beginning to a push for Mars will begin with an increase of dedication for the ISS. Probably building another one with what we learned. only then, we could start doing missions that would even look like Mars missions. Those missions would include long term space habitats outside the van allen belt. Return to the moon in a similar long term mission. Possibly exploring and attempts to mine the moon for water if the amount required and ability to gather it would pay off as opposed to shipping it up from the Earth's gravity well. Shipping supplies and equipment to Mars to await the crew and test our ability to get to Mars with such vehicles. Then we could actually send people to Mars.

We didn't go to the moon till Apollo 11.

Which was, it must be noted, only eight years after the first American went into space.

It's now been 40+ years since a human went beyond LEO...which is sad.

And this is about an order of magnitude larger than going to the moon which with 40 years past would put us about 40-60 years out from getting to Mars. Sounds about right.

Comment Realistically (Score 4, Insightful) 402

There's no conceivable way that, within the next few years, our engineering capabilities or understanding of things will be able to do a manned deep space mission to Mars, safe or not. We could try to just put a bunch of guys in a box and send it that way. I doubt we could design, build, orbit, and then get the box on it's way in the "next few years". Let's be serious. Nobody with space capability is looking at a Mars mission any time soon (next few decades*). The level of complexity needed will take time, research, and money. We didn't go to the moon till Apollo 11. Once you start seeing your Mars missions planned, let alone counting up, then we can start being serious about going to Mars. Seriously, we need to test deep space habitats. Long term independent space habitats. Long range movement of large structural objects in space. I bet we will have a deep space station and have sent something similar in a long trip around the moon long before we attempt Mars.

*Elon Musk said it's possible in the next 10-12 years. I think he is just being overly optimistic, and that is overly optimistic, to get in the papers.

People who use the banana equivalent dose don't seem to understand this rather basic and crucial fact. It's also why you don't hear experts on the subject using it.

Bring one fact into the discussion and that sort of indicates you have to bring them all in and now your discussion is way beyond anybody but an expert in understanding, if they ever finish compiling the facts. Facts are just a sure way you'll lose 99% of your audience as they fail to understand or get bored.

being gay is not a matter of religion

Romans 1

26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error. 28 Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done.

It is very much a religious issue for many people.

That's just artifacts of the English translation being unable to convey the true meaning of the scriptures. It doesn't remotely mean the same thing when read in the original Klingon.

No sympathy here. Play by the established rules and regulations or GTFO, ok?

Depends where you are talking about and which company. Most are operating under loopholes or bizarre interpretations of the laws, but aren't quite running a speakeasy of cab services. Of course, at least in Seattle, playing by the established rules and regulations means they can't enter the market as all the taxi licenses are already owned and they will not issue more. One of the companies in Seattle therefore ran under the rules that towncars and limos ran under as a charter service. It's just that with cell phone apps, the charter could be made from anywhere in seconds. Still, there are reasons that these service can even function at higher rates than taxis, and that's because that taxis, in Seattle anyway, and unreliable, inconvenient, and dirty.

If Seattle is anything like New York they make a ton of money on taxi medallions. Less taxis, less revenue. :-(

Pretty sure that Seattle is not like NYC. The issue is not that medallions to become a taxi cost money, it's that there are no medallions for sale. For the current medallion owners, less taxis mean more revenue. They use that revenue to protect their profits. If Uber or Lyft could just pay money and keep operating, they probably would. In Seattle such operations charge more money than cabs, and the people here are willing to pay it because the cabs are pretty much unreliable, inconvenient, dirty, and lack customer service. The last time I stood in the rain for over an hour because the cab company kept telling me that the first two cabs went by where I was and called my cell but I wasn't there and didn't answer, I stopped relying on taxis for transportation.

Besides, I've never been to a supermarket that serves venison.

They don't have venison in the US? Every supermarket has venison in the UK, even the cheapest ones like Lidl and Aldi. They don't have a big selection, though.

He's probably never looked for it. It is pretty rare but can be found. If they have venison, it will probably be one item, frozen, next to the frozen duck, rabbit, and less used cow organs in the bottom of the freezer section. Asian markets will probably carry it as well as exotic meat markets. Otherwise, most of the US will probably just ask for some from the part of the family that hunts when they want it.

There's no real reason to assume that this was deliberate versus a massive failure on board the plane that caused loss of most communications and navigation.

Most of the analysis I've read has pretty much stated that anything that massive that would have kept the pilots from reporting in via the various means of independent communication on the plane for the hours they were still in control, would have been so massive, the plane would not have still been airworthy. A single turn and cruise till it runs out of fuel, and there might be an argument for fire, loss of cabin pressure, or something overcoming the crew and passengers. There were at least three turns and altitude corrections in over an hours time that would have required manual control. If things were so bad that they couldn't tell where they were going and couldn't radio, they probably would have ditched and hoped for rescue with the liferaft transponders rather than fly blindly into the Indian ocean.

The Pacific Electric Streetcars went out of business because they were slow, expensive, and unprofitable. The stretch from downtown LA to Santa Monica averaged 13 mph. That was good compared to your options in 1905. By the 1930s, it was horribly slow.

This differs from driving on the LA freeways today how?

This is really obscure - it might take a couple of months, but I predict that this is at some point going to be noticed by creationists who will then read the summary (not the paper of course, just the summary) and proudly declare that this is where the water from the great flood disappeared to.

Long past that point. I can remember seeing something on the internet at least a decade ago talking about not only where the water went to, but where it came from to begin with. The idea that there is water trapped deep in the mantel is not new or surprising. It has been known for along time, this is just more and better evidence.
