A brief blurb about a new formation channel for Wolf Rayet stars.

http://phys.org/news/2015-05-hubble-one-of-a-kind-star-nicknamed-nasty.html

Maybe of interest because Art and Michio Kaku captured our collective imaginations with the discussion of WR104 on the first DM show? :)

I don't remember how the lone gunmen died...
luckily there's time to do some catching up before the new episodes come out!

All the best Art. Hope you feel better soon.

Gillian Anderson back as Scully?
*gush*

So far all the netflix series have been well produced, I hope the same holds for the new X-Files episodes. Also really hope the series does well and comes back beyond the first six.

So we have a physicist and a chemist on the board?  I can say that hearing AO he would be good for commentary as he has the voice and the ability to explain what he is talking about and dumb it down for us mere mortals.  Possibly chefist could comment on the danger of all drugs and how c-a-r-i-n-o-v-a can cure any ailment? ;)
So far the weekend has been good...  It would have been great to hear you call in during the interview.  Art has a history of letting smart and knowledgeable callers run with it for awhile while sitting back and listening.

I don't know how I forgot about Astroguy... I have even enjoyed listening to his podcasts...

You are too kind Wotr!

I vote for Astroguy as a guest, he definitely has the presence and experience to make for interesting conversation. And, I'm sure, would be better suited to do battle with all sorts of callers. :)

Wow that's cool. Some of my best friends are chemicals.
haha
Hey Aldous, long time no speak. How's the cacti in your part of the world?

Hi AO...what's your science background?  Just curious...I'm a chemist...

Hi Chefist
I have a Ph.D in physics and I specialize in astrophysics. I'm currently just a lowly post-doc in the grim and frostbitten great white north. My main interests are in theory and computational work. What kind of chemistry do you do?

Hey also, did Don Zaidle only do one show with Art? I keep running across the interview where he promoted a book called "American Mankillers" and I remember back in the day his stories about animal attacks kept me on the edge of my seat. One of my favorite shows that Art ever did.

AO!!! Please call into MITD a few times to discuss all things science.
Hey wotr! How's it going?
I'm kicking myself for not calling in the first DM show with Michio Kaku on it. One day I'll speak with both of them! :)

I.  Don't.  Have.  The.  Words.   8)

Going good, your jones will soon be satisfied.  It's been quite a ride just getting ready for it, as Art has been keeping us in the loop on some of the production.  Been wondering when you were going to show up again.   ;D

Waiting for the times to get better...

But glad to be back in the meantime (even if just to poke my head in).

Also how cool is it that Art still walks among us?!

Hey

Just wanted to drop by and say hello and thanks for all the free entertainment. Making my way through the shows, not caught up yet, but savoring each one. :)

The most interesting new approach for me with respect to the UFO business has been Greg Bishop's stance that was generally adopted in the film Mirage Men. The combination of psyops and experimental aircraft would have been just the right mix to perk up my ears back in the days when Art was on the air and I'm enjoying how this show has explored that general theme. So it's nice to hear Ty Rogoway (sp?) and others expand a bit on aspects of the air defense and secret projects that are apparently behind the scenes. Other than the information on these shows I have not done much reading on the Bennewitz/Doty affair and I found that story also extremely interesting.

Actually a lot of the "contactee" stories from the fifties and sixties take on a different (and much more sinister) air when examined with the idea that high grade psychedelics and narcotics were being commonly experimented with as weapons and interrogation methods during that timeframe. After all, how many of the contactees had to eat or drink something before they had their claimed experiences? I feel it adds a bit to the eerie atmosphere around some of these stories regardless of their actual nature.

Agent : Orange!

Live stream will be free, downloadable podcast without music & other perks $5 a month.  Last one to the party is a square.  Art says he will have more, but can't reveal everything now.

Hey Red how's it going? Good to see you up & around!

The other day I was jonesing for new content and hoped the plans were still going forward. Very happy to hear they are.

I love the name Midnight in the Desert, glad that this is happening.

Is the plan for free live streaming but paid archives? Or is a subscription needed to listen live as well? Thanks

Also.... is ... is that Fort Rock on the tab for this site now?

It just takes a few months for the place to go to the scorpions...

Newly-found gravitationally-lensed galaxy ring as predicted by Einstein's theory of general relativity. 

"Astronomers have discovered that a distant galaxy—seen from Earth with the aid of a gravitational lens—appears like a cosmic ring, thanks to the highest resolution images ever taken with the Atacama Large Millimeter/submillimeter Array (ALMA) [...] Discovered by the Herschel Space Observatory, SDP.81 is an active star-forming galaxy nearly 12 billion light-years away, seen at a time when the Universe was only 15 percent of its current age. It is being lensed by a massive foreground galaxy that is a comparatively nearby 4 billion light-years away. [...] Gravitational lensing occurs when a massive galaxy or cluster of galaxies bends the light emitted from a more distant galaxy, forming a highly magnified, though much distorted image. In this particular case, the galaxy known as SDP.81 and an intervening galaxy line up so perfectly that the light from the more distant one forms a nearly complete circle as seen from Earth."




*gush*

This paper ( http://arxiv.org/abs/1503.08720 ) does a jaw-dropping job modeling the total lens mass distribution and also the source light distribution. Amazing.

Hey everyone, nice to see this thread is still around!! It's been so long since I have bounced around this place...
 
My plan was to skype into the last gabcast but sadly my Dad was readmitted to hospital yet again on that exact day so needless to say I missed the show. Between dealing with that ongoing saga and my work I have not had time for much else online. But I'm proud to say I have had my first solo-authored paper accepted by a well-known journal in March and I am still grinding on (for now).

Hope everyone is doing well and the skies remain clear.

... and before I get off on a rant let me say its my opinion this EM-drive and Alcubierre business that's being tossed about online (say, http://www.dailymail.co.uk/sciencetech/article-3063082/Has-Nasa-built-WARP-DRIVE-Engineers-claim-tested-impossible-engine-travel-faster-speed-light.html or http://io9.com/new-test-suggests-nasas-impossible-em-drive-will-work-1701188933), along with any other system that claims to break classical conservation of momentum is really most likely bunk. If I were forced to bet I will say that these effects will go the way of OPERAs faster than light neutrinos before long. ;)
But - of course - that lack of vision may be why I'm not working at NASA right now! Meanwhile I'll be keeping my fingers crossed even if the outcome doesn't look great.

This has more ups and downs than the unfolding Art Bell saga  ;) .

Absolutely!

There's a lot on the line and the measurements are extremely difficult to make so people are scrambling for any clues they can find that will help in moving on.
There's still room for this to be a dust contaminated signal but we have to wait for the upcoming observations to know that for sure. What is clear is that there is a signal over what is expected from the standard cosmology and that signal remains consistent with BICEP2.

The previous BICEP2/planck paper from two days ago shows there is some contribution from dust in the B-mode signal, so that some of the signal must be the result of dust. But it does not mean all of it must be from dust. There's still room for primordial B-modes in the BICEP2 data. That's why its so important to get this new paper from Keck. Maybe there is something more interesting there beneath the surface that needed a better instrument to be studied. We'll see.

 

21
Amazing paper just posted to the arXiv a few hours ago, the Keck array seems to argue for primordial B mode gravitational wave signature consistent with BICEP2 and not due to systematics.

http://arxiv.org/abs/1502.00643

The situation is even more exciting now! I'm sure this will attract a lot of discussion in the next few weeks...

No mention of dust or how to distinguish primordial B-modes from dust, but this says plenty about the ability to detect gravitational waves. Will be interesting to see what multiple frequency observations have to say about all of this.

22
Looks like the BICEP2 results on primordial B-modes (gravitational waves) in the early universe were incorrect after all. The joint paper they collaborated with the Planck team acknowledges they likely just detected polarization from galactic dust.
http://phys.org/news/2015-01-planck-gravitational-elusive.html
Too bad... but there may still be primordial B-modes lurking out there somewhere, waiting to be discovered.

Exciting times

its like you have 2 apples. you double the number of apple you have (2*2) for a total of four. but mathematically -2*-2=4 is also true and a mathematically valid answer.

The problem is it may not make "sense" as we understand it to say a negative number (or imaginary) is at all valid for some quantities. Like magnetic monopoles. Maxwell's equations are set up to ignore magnetic "charges" since we have never seen one and thus we conclude they don't exist. If they did they could be accommodated easily. But such things have never been seen (and no evidence exists for them) so we discount them. Including them becomes and interesting mathematical game of "what if". It's tough to answer if such things might really be possible, which is why we need experiment to put physics on the right track.


25
So, like a cosmic strip club?

^^^ this.

You may only think what you're seeing is real.

Art should avoid all of these difficulties and become a host on the gabcast. Boom, production problems solved

27
Tachyons are real?  I thought they were just a Star Trek Next Gen. device.  Will have to look into this.
They're not physically "real", but they do come from real theory. You can take physics and put exotic bits of math into it (like tachyons, or exotic matter, or whatever) and see what it would be like afterward. But it doesn't mean things are really like that.

28
This is dated and I don't know if it's accurate, but a kinda cool musing on photons.

http://www.propermotion.com/jwreed/Essays/The%20Life%20of%20A%20Photon.htm

This was a neat article. But the real punchline for me is that the observer's eye and Andromeda are the same place and time for the photon in that story!

29
All about tachyons, better than I could say it and right from the horse's mouth!

Indeed.  Matter with negative mass would have negative inertia and possibly negative gravity? which would be strange indeed.  I'm not sure such a thing is possible but I have been curious since the late 90s whether it could be an explanation for the great voids and large scale structure, and some of the effects we see, like the Great Attractor, which I propose is really the Great Repulsor, as two great voids attempt to merge.  It's probably pretty silly, but that's what I'm here to find out.

Theorists love to talk about "exotic matter" which is pretty much just negative energy (or negative mass) to stabilize finnicky solutions. It's how we got started talking about traversible wormholes and warp drives. It can give interesting mathematical behavior in some cases and even if it's not physical it might make a solution interesting in a different way.

It's basically the equivalent of "yes, and" for a theorist.

Certainly some kinds of physical effects are measurable and related to negative energy (like the Casimir effect http://en.wikipedia.org/wiki/Casimir_effect), but it's not really understood yet how it can be used or in what quantity or what real applications such things may yet have.
