IOW, the black hole burped.

How do we know it is a burp and not a fart?

How do we know it is a burp and not a fart?

it went out the same way it came in?

Perhaps - if some scientists are correct in theorizing that black holes release bubbles of new universes on the other side, the new universe could be considered a fart. Actually, that pretty well implies that our universe is a fart, which makes perfect sense.

The tribe of some 400 neuroscientists, computational biologists, physicists, physicians, ethicists, government science counselors, and private funders convened at The Rockefeller University on Manhattan’s Upper East Side in New York City. The Coordinating Global Brain Projects gathering was mandated by the U.S. Congress in a 2015 law funding the U.S. Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative

At the Rockefeller meeting, an important impetus behind the big ambitions—the quest to decipher the gamut of human brain diseases that are still incredibly poorly understood—was evident in the room. “It’s purely getting at the [brain] circuits that’s going to tell us about schizophrenia, autism, multiple psychiatric disorders,” Walter Koroshetz, the director of the National Institute of Neurological Disorders and Stroke at the National Institutes of Health in Bethesda, Maryland, told the assembled scientists. Yet our current neuroscience tools are so rudimentary, he noted, that watching the brain function in real time is like “trying to understand what Gone with the Wind is [about] by watching it one pixel at a time over and over again.”

Predicting earthquakes through satellite. http://www.scientificamerican.com/ar...d-earthquakes/

Scientists have a new tool that could help them predict earthquakes induced by the effects of pumping wastewater from oil and gas operations deep underground—and it’s in orbit. A team of geophysicists analyzed more than three years of radar data from the Japanese Advanced Land Observing Satellite (ALOS) and found they could see the land deform above wastewater disposal wells near Timpson, Texas. Two years later, in 2012, a magnitude 4.8 earthquake rocked the area.

Elon Musk says he plans to have humans on Mars in 6 years. I'll take the over. https://www.theguardian.com/technolo...ex-mars-colony

SpaceX founder Elon Musk has outlined his highly ambitious vision for manned missions to Mars, which he said could begin as soon as 2022 – three years sooner than his previous estimates.


However, the question of how such extravagantly expensive missions would be funded remains largely in the dark.

I'm not as smart as Musk, but I am smart enough to know that that particular question is just as important as "How do you get your stuff there?"

In order to achieve this goal, Musk outlined a multi-stage launch and transport system, including a reusable booster – like the Falcon 9, which SpaceX has already successfully tested – only much larger. The booster, and the “interplanetary module” on top of it, would be nearly as long as two Boeing 747 aircraft. It could initially carry up to 100 passengers, he said.

The first ship to go to Mars, Musk said, would be named Heart of Gold as a tribute to the ship powered by an “infinite improbability drive” from Douglas Adams’ science fiction novel The Hitchhiker’s Guide to the Galaxy.

If he actually does launch that ship in 6 years... I got money on it failing due to poor planning and people dying. Slow and steady wins the race in the end.

It is surprising, isn't it? It's not like that's a guy known to go off half-cocked, bold to be sure, but not irresponsible. I am surprised he announced while also even admitting that he didn't have any funding set up. Of course, it's possible that the announcement actually was meant to stir funding.

More on same. Getting wide coverage today. http://www.esquire.com/news-politics...nization-plan/

One of the fundamental pillars of Musk's plan is to make it reasonably cheap to get humans to the red planet. By his estimates, sending humans to Mars with traditional tech would cost as much as $10 billion per person, a price tag that makes creating a self-sustaining colony something reserved to science fiction. But Musk, being the boundary pusher he is, has a different ticket price in mind: The median price of a house in the United States. That is, just a few hundred thousand dollars.


The key technological milestones to making this happen, according to Musk, are reusable spacecraft, orbital refueling, propellant production on Mars, and some really good propellant, specifically "Deep-cryo methalox" or CH402 because it's relatively cheap and can be made right on Mars

Just me... but before I strap myself to a combustible cylinder to go to another planet... I'd LOOOOOVVVVE to see a little proof that you can actually do it... repeatedly. THEN and only then would I do it. JMHO, 6 years isn't enough time to do that. It just isn't.

Yeah, but one's got to figure they're at least going to send supplies ahead of time with the same system. But, that doesn't change the fact that you're right. Doesn't really matter how many supply runs they use in the intervening years - can't be that many, yet, with no money - just not enough to really ensure kinks are worked out. Some will go, no matter what. Just risky.

Alan Shepard rode a Redstone, suborbital in 1961 for our first trip out of the atmosphere. While I was a youngling at Vandenberg, they were testing the Atlas, and many blew up. That is what John Glenn rode for the first orbital flight. They developed the Titan, Saturn and Jupiter to land a man on the moon, all within a 9 year span and starting from scratch.

I don't know if he will be successful, but if he can find the answers to the fuel situations, it is possible in 6 years. He already has much of the groundwork laid. Would I go up? Probably, bad ticker and all, just because!

True.

But - and Will, you know how it is that I know this - NASA's budget at that time, was 5% of the total federal budget. Extraordinary even before you count the fact that those missions used as much military money as they did civilian, even though that couldn't be said out loud.

Your main point is that it was an unbelievably audacious plan, completed. And that's certainly true. Probably in no small part b/c it was done by a generation that had no problem thinking big, the tail end of that generation rightly called the greatest. They had the wherewithal, the drive, the shared sacrifice, all to put such money into it that they could have completely different teams working on each mission all at the same time, allowing for one after another. Amazing, as you note. Just, the money needs acknowledgment, it did help.

Well, it's been nice foo-ing around with you folks.

Great article. Pretty f00-typical. I finally get a great regular contributor to the science thread and a couple weeks later, you end up with a house on the bottom of the Pacific.

But, don't max the credit cards just yet, as you read:

But as the USGS researchers point out, this is far from an inevitability. The swarm under the Salton Sea may subside, or fail to influence the gigantic fault nearby. Moreover, the estimates provided by the scientists are exactly that—estimates. The science of earthquake prediction is still very much in its infancy, and these models are very likely crunching away with insufficient data. No need to panic just yet.

I think the people of Seattle/Portland have more to fear in terms of sheer devastation than So. Cal, with the horrific earthquake followed by a wall of water. And, there's is well-overdue.

What's with NASA and those guys smashing everything into planets and comets now when the mission is done?

The historic Rosetta mission has finally come to an end. Over the past two years, the probe’s many instruments have scanned virtually every nook and cranny of this weirdly shaped rock, Tunleashing a treasure trove of new information about comets in general, and 67P/Churyumov–Gerasimenko in particular.

Even as Rosetta made its final death plunge onto the surface of the comet, mission scientists were busy collecting data. Its final resting place—named Ma’at after the ancient Egyptian goddess of harmony, balance, and order—is a region strewn with boulders and treacherous sinkholes. By exploring this area in detail, scientists hope to gain a better understanding of how comets form.[/QUOTE]

Anyone else really excited about the total eclipse in 2017? Definitely a near once in a lifetime chance. http://www.eclipse2017.org/2017/path_through_the_US.htm





For Idaho - one of the closest to WA

IDAHO

On to Idaho, where Stanley and Mackay are the first recipients of lots of shadow. Idaho Falls is in the path, but south of the centerline - so it only basks in the umbra for 1m49s at 11:33am. Rexburg does much better, getting 2m17s at the same time.

The highest point in Idaho - Borah Peak - is in totality, and that might not be a bad place to be for the more adventurous types!

But that's it for Idaho - Boise and Pocatello are NOT in the path of totality! Do not stay home, and think you're getting a good show, because you're not! Get north, and get into the shadow! IN BOISE OR POCATELLO, the eclipse will never be total for you! You will need to use your eclipse glasses for the entire partial eclipse!

OREGON

And that land will be United States soil. On the beach in Oregon, at a rocky spot of ground just north of Newport that sticks its nose out into the Pacific, the shadow first touches land at 17:15:50.6UT (at about 10:15 in the morning). This lucky piece of earth experiences a full minute and fifty seconds of totality.

The actual centerline of the eclipse path hits solid ground a full six seconds later, and plunges Lincoln Beach and Depoe Bay into darkness for 1m58s!

It takes only about two minutes for the shadow to race eastward toward its first date with a large population of folks who will be breathlessly awaiting its arrival. Dallas, Albany, Corvallis, Lebanon, Philomath, McMinnville, Woodburn, and yes, Salem itself, experience various durations of totality (based on their varying distances from the centerline); on the steps of the State Capitol in Salem (the first of five state capitals the shadow will visit), lucky viewers will be treated to 1m54.5s of shadow at just after 10:17am. (Great time for a coffee break!)

The great city of Portland is NOT in the path of totality! If you're there, or in Eugene, you will not get the full meal deal! Get south, and get yourself into the shadow! That's right: IF YOU STAY IN PORTLAND, the eclipse will never be total for you! You will need to use your eclipse glasses for the entire partial eclipse, and you will not see the beauty of totality!

A dying star spitting out planet sized balls of fire? Cool. http://www.livescience.com/50718-weekend-reading.html

The high-speed blobs, each double the mass of Mars and twice as hot as the surface of the sun, are moving so fast in space that they would take only half an hour to go between the Earth and the moon (238,900 miles, or 384,472 kilometers), according to a statement from NASA's Jet Propulsion Laboratory. The observations suggest that these balls of fire have been appearing every 8.5 years for at least the last four centuries, the statement said.

‘

We knew this object had a high-speed outflow from previous data, but this is the first time we are seeing this process in action,’ said Raghvendra Sahai of NASA's Jet Propulsion Laboratory in California, who led the study.

‘We suggest that these gaseous blobs produced during this late phase of a star's life help make the structures seen in planetary nebulae.'

If it ever got to that point with the sun and earth, we'd have to figure out a way to stop the Earth's rotation, so at least everyone could hang out on the back side and use the other side as a shield. Perpetual night would be a bit of a downer, but better than being hit by a ball of fire 2x as big as Mars.

More mission to Mars news, this one appears to be a bit more realistic than Musk's plan, in the 2030s. http://www.huffingtonpost.com/entry/...f7b5?section=&

In a column published by CNN, Obama shared new details about how NASA and its corporate partners plan to reach Mars and return to Earth, outlining a vision much like that of billionaire business magnate Elon Musk, the founder of SpaceX.

“We have set a clear goal vital to the next chapter of America’s story in space: sending humans to Mars by the 2030s and returning them safely to Earth, with the ultimate ambition to one day remain there for an extended time,” Obama wrote. “Getting to Mars will require continued cooperation between government and private innovators, and we’re already well on our way.”

.

In a joint blog post on Tuesday, White House Senior Advisor John Holdren and NASA Administrator Charles Bolden discussed other developments in America’s planned journey into deep space. They said six companies had received awards to develop habitation systems for long-duration space missions, including to Mars.

“Make no mistake, the Journey to Mars will be challenging, but it is underway and with each one of these steps, we are pushing the boundaries of exploration and imagination for the Nation,” Holdren and Bolden wrote.

A bit of a local angle, Boeing seems heavily involved as a private contractor.
