Matt Taylor lands a module on Comet 67P/Churyumov-Gerasimenko, some 300 million miles from Earth.

Some imbecile monkeys bully him because of his shirt.

Over the last few days, we have learned that mankind can chase down a comet speeding through space at 34,000 mph, but resisting the outrage machine, kicked into high gear over a trifle, is completely beyond its powers.

who the fuck let these ape-women bully this man who set a great new step in space-discovery?!

Stupid, shit-flinging femtards!

I think pandering to business-culture would be a bigger joke. I mean how sad would it be if you spend decades letting your boss tell you how to dress, until you finally get to the top of your field and realise that you still have to let the audience (who honestly don't care if you live or die) tell you how to dress?

Not that I know anything about anything, but I had a few ideas to make getting into space easier, maybe, but probably not. The space elevator has a shitload of engineering challenges to surmount before it's workable. Materials challenges, construction challenges, hell even environmental challenges. Let's think outside the box.

Idea 1: We build a huge, elliptical track around the Earth that at it's nearest point passes within 75,000 feet of the highest peak (something like 100,000 feet above sea level). You take a plane to the track, load onto a spacecraft and away you go to the other end of the ellipse where you're more like 1 million feet from Earth.

Idea 2: Place a solar orbiting space station 100,000 feet outside of Earth's orbit (75,000 plus 25,000). Have the station travel just fast enough to avoid getting caught by Earth's gravity, and about once a year (or maybe not) the Earth and the station make a close pass during which cargo and passengers can be transferred from planes to the station. Rockets can then be launched from the station.

I'm sure these ideas are both bad. Very bad. The both pose engineering challenges that dwarf those of the space elevator. The important thing though is that we're thinking outside the box. What kind of bright ideas have you got?

Passengers, yeah, but fuck the passengers, bring them up there in space shuttles or something AFTER you've already chucked the materials up there with lethal velocity. Seriously. Build a sturdy ass series of spherical units, fire them all up there, and then send a couple guys up to link them together. You'd have something four times the size of the international space station and you won't have had to bring it up with the dudes.

>The biggest sunspot to grace the face of the sun in more than two decades just rotated out of Earth's view, but it was responsible for kicking up some truly amazing solar activity this week.

>The sunspot (called Active Region 12192 or AR 2192) shot off four powerful flares in four days recently, with many more smaller flares sprinkled in as well. The sunspot region was about the size of the planet Jupiter and is the largest solar flare observed in 24 years.

>AR 2192 was actually one of the biggest observed sunspots of all time, ranking 33rd largest of 32,908 active regions since 1874, according to NASA scientists C. Alex Young and Dean Pesnell. But how does a sunspot grow this big?

/SAGAN/ How long have we really been studying the cycles of the sun? How likely is it that some magnetic vortex that has been twisting into knots for the last several centuries will just let loose and shoot plasma or radioactivity into the rest of the solar system? haven't we really only collected data on the sun for like the last 100 years? 150 years tops? Isn't that just a blip in the life cylce of our star?

There are lots of anomalies in the sun's activity. I read somewhere that the sun's magnetic field is not acting according to projections, and in the last 25 years, that the sun's surface temperature has been much hotter than projected.

Actually, the observation of sunspots goes back farther than most other modern astronomical data, predating telescopes. Thorough day to day records are probably only to be had for the last 100 years or so, but many interested astronomers in the last few centuries kept sketches of sunspot activity periodically.

weve been studying it since we began. it makes a pretty obvious thing to wonder about. weve been studying it scientifically since science began. with telescopes when telescopes began. not much else can lay the same claim to our attention historically. basically weve been keeping an eye on it so its unlikely to do something now that we havent seen in recorded history (with the tools available to us at those times) or from what weve seen in the geological record.
obviously the mayans didnt understand solar flares but if part of mexico had been zapped to a crisp in recent time im pretty sure wed have both historical mentions and physical proof.

So is the concept of a multiverse basically saying that anything past our observable universe if another universe? Is there a stretch in space which is officially not out universe? Or is there a no mans land sort of thing. I know we don't know this but I'm just wondering if anybody can give me some insight into the matter.

In your example, no, there is no strip of non-universal stuff. Our observalable universe is limited by the distance light could have traveled in the time the Universe has existed; but that means that diffrent points in space have diffrent observable universes. Take a map, a cup, and a pencil, place the cup over the map with LA at its center, now do the same for San Fransisco; you might have some overlay, and you also have some areas that don't overlap, and areas like Russia that probably aren't in either circle (unless you have really big cups or a really small map) still exist. Talking about observable universes as separate is mostly an observation of the fact that we cannot hope to travel outside this boundary because of the laws of physics (or our current understanding of them) rather than an observation that those areas of space we cannot reach are fundamentally different.

In other multiverse theories there may or may not be areas that are not part of any universe. There is a theory that the greater-universe is a big homogenous rink of energy and that our universe (what we usually call the Universe) is a random fluctuation in this field and there are other fluctuations (other universes) elsewhere in field; in that case, those homogenous regions without fluctuations would not be a part of what we usually like to think of as a universe.

That's called a level 1 multiverse.
Everything beyond our Hubble Volume is technically another universe.
A Hubble Volume is everything contained within the boundaries of the CMB.

And then there's the level 2 multiverse which has more to do with Probability and is highly theoretical.
Every Plank Frame (smallest possible unit of time) we jump between possible states across the 5th dimension as we travel along the 4th dimension. The other level 2 universes are probabilities that did not happen. Maybe. Like I said, HIGHLY theoretical.

Cosmic Natural Selection from wikipedia:

The theory surmises that a collapsing black hole causes the emergence of a new universe on the "other side", whose fundamental constant parameters (masses of elementary particles, Planck constant, elementary charge, and so forth) may differ slightly from those of the universe where the black hole collapsed. Each universe thus gives rise to as many new universes as it has black holes. The theory contains the evolutionary ideas of "reproduction" and "mutation" of universes, and so is formally analogous to models of population biology.

Do you think this is possible?

You realize semantics are not gospel, right? There are no physical sides to an event horizon because an event horizon is not a physical thing; if you were falling into a black hole you probably wouldn't even observe the event horizom. The event horizon is no more a physical feature than the Goldilocks zone... You can talk about it, but it doesn't really do anything in and of itself, it's just a descriptive label.

No need to strap a bomb, when you could just carry a tungsten rod and just drop it down the gravity well.

When we're dealing with space tech, the energy involved means everything can be dual-use as weapon.

It's the chicken and egg problem, to demonstrate a working prototype, you would need funding to put model into physical world.

Before a working prototype exist, it's been hard for the those approving funding to judge the energy-in and energy-out estimates in the models.

I don't wish to incur the wrath of the more knowledgable, but the way I have conceptualized any "holographic universe" theories is that their distinctness from string theory is mostly derived from new age spiritual implications made by the authors and that it attempts to explain things in a similar way. but from a perspective relying more on home-spun analogies than on the process academics tend to use.

Basically, I think describing the universe as a hologram of a lower dimension, or as a reflection of a higher dimension is functionally identical to the average person. Whether you describe it as super-string shadows or as holograms depends on who you read. This isn't to say they are perfectly equivalent. I believe string-theory has been subject to far more scrutiny and is thus more useful for informing research.

guys guys 2d simply refers to the fact that the information of 3d space is projected much more accurately on a 2d plane rather than the 3d space itself. Like the "film" to project a movie is a much more accurate description of the movie than the actual movie which has depth. the screen or the film dont.

The problem with this is that in 2d, the configuration or code of the 3d space is completely scrambled so we can't make it out what it would look like in a 3d space.

Russia got another rocket up with supplies already. It's not really the ISS supplies that matter, since they are an easy, relatively cheap payload that can be launched from many sites on the planet. The real loss here was the experimental cryptography technology that was on board. An experiment that may have cost as much as or more than the rocket itself was likely destroyed in the accident but because it's classified we don't get to know exactly what it was or how much it cost.

The space station has enough supplies to last until well into next year, and there are plenty of other launches scheduled in the meantime (from Russia and the US).

The Dragon capsule just returned last weekend from a 4 week resupply mission, and Spacex is scheduled to launch another one on December 9th. They're going to slightly modify the manifest to account for OSC's failed launch. This one's going to be even more interesting, because they might try to LAND the first stage on a floating platform after separation (albeit with less than 50% chance of success)
