We're still here no one noticed a thing but NASA who is always after our money.
There must have been waves that preceded that big one, because I remember it being reported here - and it was being connected (here) to the Boxing Day Earthquake of December 26, 2004.

Edit to add: and now that I'm actually watching the video, that's exactly what he's mentioning - the connection of the last one with the earthquake.

Also, I bumped up a thread in Unexplained of my dream that may (or may not) have something to do with this. I posted the dream again at the end of the thread.

Maybe the pope and the queen heard that this was coming right before Christmas, not right after. Which reminds me: doesn't the vatican have its own space observatory? Something about their fascination with demons, er, aliens and UFO's.

Not a religious or sectarian event.

Science - and fairly shaky science at that.

Woo, imo.

Does anyone happen to know where to watch the 2013 show "The Carrington Event"? It apparently was intended as a pilot for a doomer TV series, but the series never got made. I can't find it on YouTube but maybe there are other sources? Heck, I'd even consider buying a DVD if that's the only way to watch it.

Is anyone ever REALLY "ready for crazy SHTF stuff"?

The most significant prep is MINDSET.

And I would muse also faith. I know that is included in mindset, for the religious prepper. But I felt the need to say it. Also the mindset/experience to eat bugs, harvest, gut, skin and butcher most anything.

Soon we'll be hearing that it's Trump's fault! I'll worry about it when 12/26 gets here, until then I've got places to go and people to see.

Yep. Not a damn thing you can do about it, no sense getting all worked up. Whatever happens, happens.

The problem with the theory is that it is impossible to detect gamma rays before they arrive. They and any other kind of electromagnetic radiation, travel at the speed of light and nothing travels faster, so the first indication you have of them is when they arrive.

Exactly right. Which is why this story can be immediately concluded to be fake.

I was think about the only way you could know in advance is if an event involved a collision of two bodies. You might be able to see that collision coming and predict it and the events that follow. Even though by the time you even ever predict it- it has already occurred many years ago, and the result has been on the way for many years. Come to think of it this could also apply to seeing a certain event in a single body that preceded a known consequence.

The terminal effects of ANYTHING energetic diminish with distance and time. If this has been traveling through space for years over light years -

Unfortunately gamma rays are thought to involve beamed emission along two jets in opposing directions. Basically the collapsing star becomes a very, very large gamma laser. If you just happen to be in the path one of these jets only extreme distance, ie NOT in our galaxy, can save you. Take Betelgeuse for instance. This red giant in the constellation Orion is the ninth brightest star in the heavens and is only 640 light years away. It is thought to be a prime candidate to go nova.

From what i understand. The last major Galactic wave to hit Earth, was on December 26th 2004. The same time the 9.3 Sumatra Earthquake occurred. The wave also caused a hole in the Earths south pole. The same hole that was blamed on global warming after. This also was the first time we had satellites up to detect this kind of phenomenon.
Now this Galactic wave have 5 parts. The first wave has passed mid October, thus, an uptick on large quakes. The second wave, which will be the strongest, more stronger then the 2004 wave, and more of a DIRECT HIT then the wave in 2004. Will pass Earth on December 26th.
The take out of this, is a high probability of very strong earthquakes around the 26th and the Earths atmosphere could get torn again. Satellite and power grid problems could occur. Also animals, including humans, face a higher rick of cancer from these interstellar waves.
The direction of this Gamma Galactic wave, is the opposite direction then the sun.

Gamma rays in this instance are the equivalent of an explosively formed projectile.

PREPARE AS BEST YOU CAN AND DON'T SWEAT IT.

I covered all of this in my ebook "Day of the Dogs." The Carrington Event actually happened in 1859 and caused widespread damage, including physically melting telegraph lines among other things. This was a CME, related to a massive wave from our sun. CME events are not uncommon, and vary in size and scope. They could, if big enough, and pointed directly at Earth cause major damage to our electric grid, communications and transport systems.
What this guy is talking about is not that. He is talking about a Nova level explosion of a star light years away. Well, obviously stars explode from time to time. Obviously they "may" hit earth with a wave of energy. However, to go from that scientific fact way out into "woo woo land," is a bit of a stretch. Finally, to link an energy wave to triggering volcanoes and earthquakes on Earth, well I don't think the science is there for that. EMP level issues with various technology is certainly possible.

Personally, I am going to wait until 12-26, which is Boxer Day by the way, and see what happens. This falls into what I call the "if it happens we are screwed, but can't really prepare for it. This is collapse of Roman Empire level doom porn. I have long felt if I can't realistically prepare for an event, I don't sweat it. In my other post I said that there is a certain type of doomer event that most of us can't prepare for. Unless you have an underground bunker you are out of luck.

Doomer Doug handle not withstanding I am not going to sweat this until 12-27-16. Even then, I doubt I will be able to deal with it at all.

Dennis, it is always Bush's fault.:kaid:

Finally, this sounds like Sorcha Faal level woo woo to me. And Sorcha Faal is a FRUITCAKE down to the last Mango!

Yes, they do. It is atop Mount Graham in Pinaleno Mountains is SE Arizona near Safford. Believe Mount Graham may be the highest peak in Arizona. If not, then certainly close.

Fortunately for us the Sun and the heliosphere etc are pretty stable not liable to periodic energy blasts, yes CMEs may happen but they don't necessarily hit Earth and if they did the atmosphere would deal with it........the greatest danger to Earth is/are meteorite or comet hits.........

Its in the FUSA? Figures. Here I thought they had it on-site, behind the mega-wall that surrounds the vatican, which has its own zip code, post office, and jail (to name a few). The Catholic church owns some of the primo real estate, globally.

From what I understand, the telescope and observatory are pretty massive...guess that spot in AZ would be prime real estate for alien encounters...yi!

No part of the earth is protected or different than any other part of the Earth, any Alien encounters would have nothing to do with religion but probably anywhere where they could get away with no credible sightings, even if there were credible sightings no-one would believe them anyway..........

Executive Order -- Coordinating Efforts to Prepare the Nation for Space Weather Events


THE WHITE HOUSE,
October 13, 2016


EXECUTIVE ORDER
- - - - - - -
COORDINATING EFFORTS TO PREPARE
THE NATION FOR SPACE WEATHER EVENTS

By the authority vested in me as President by the Constitution and the laws of the United States of America, and to prepare the Nation for space weather events, it is hereby ordered as follows:

Section 1. Policy. Space weather events, in the form of solar flares, solar energetic particles, and geomagnetic disturbances, occur regularly, some with measurable effects on critical infrastructure systems and technologies, such as the Global Positioning System (GPS), satellite operations and communication, aviation, and the electrical power grid. Extreme space weather events -- those that could significantly degrade critical infrastructure -- could disable large portions of the electrical power grid, resulting in cascading failures that would affect key services such as water supply, healthcare, and transportation. Space weather has the potential to simultaneously affect and disrupt health and safety across entire continents. Successfully preparing for space weather events is an all-of-nation endeavor that requires partnerships across governments, emergency managers, academia, the media, the insurance industry, non-profits, and the private sector.

It is the policy of the United States to prepare for space weather events to minimize the extent of economic loss and human hardship. The Federal Government must have (1) the capability to predict and detect a space weather event, (2) the plans and programs necessary to alert the public and private sectors to enable mitigating actions for an impending space weather event, (3) the protection and mitigation plans, protocols, and standards required to reduce risks to critical infrastructure prior to and during a credible threat, and (4) the ability to respond to and recover from the effects of space weather. Executive departments and agencies (agencies) must coordinate their efforts to prepare for the effects of space weather events.

Sec. 2. Objectives. This order defines agency roles and responsibilities and directs agencies to take specific actions to prepare the Nation for the hazardous effects of space weather. These activities are to be implemented in conjunction with those identified in the 2015 National Space Weather Action Plan (Action Plan) and any subsequent updates. Implementing this order and the Action Plan will require the Federal Government to work across agencies and to develop, as appropriate, enhanced and innovative partnerships with State, tribal, and local governments; academia; non-profits; the private sector; and international partners. These efforts will enhance national preparedness and speed the creation of a space-weather-ready Nation.

Sec. 3. Coordination. (a) The Director of the Office of Science and Technology Policy (OSTP), in consultation with the Assistant to the President for Homeland Security and Counterterrorism and the Director of the Office of Management and Budget (OMB), shall coordinate the development and implementation of Federal Government activities to prepare the Nation for space weather events, including the activities established in section 5 of this order and the recommendations of the National Science and Technology Council (NSTC), established by Executive Order 12881 of November 23, 1993 (Establishment of the National Science and Technology Council).

(b) To ensure accountability for and coordination of research, development, and implementation of activities identified in this order and in the Action Plan, the NSTC shall establish a Space Weather Operations, Research, and Mitigation Subcommittee (Subcommittee).

Did Deadly Gamma-Ray Burst Cause a Mass Extinction on Earth?
By Charles Q. Choi, Live Science Contributor | December 8, 2014 07:02am ET
http://www.livescience.com/49040-gamma-ray-burst-mass-extinction.html
A gamma-ray burst, the most powerful kind of explosion known in the universe, may have triggered a mass extinction on Earth within the past billion years, researchers say.

These deadly outbursts could help explain the so-called Fermi paradox, the seeming contradiction between the high chance of alien life and the lack of evidence for it, scientists added.

Gamma-ray bursts are brief, intense explosions of high-frequency electromagnetic radiation. These outbursts give off as much energy as the sun during its entire 10-billion-year lifetime in anywhere from milliseconds to minutes. Scientists think gamma-ray bursts may be caused by giant exploding stars known as hypernovas, or by collisions between pairs of dead stars known as neutron stars. [Top 10 Greatest Explosions Ever]

If a gamma-ray burst exploded within the Milky Way, it could wreak extraordinary havoc if it were pointed directly at Earth, even from thousands of light-years away. Although gamma rays would not penetrate Earth's atmosphere well enough to burn the ground, they would chemically damage the atmosphere, depleting the ozone layer that protects the planet from damaging ultraviolet rays that could trigger mass extinctions. It's also possible that gamma-ray bursts may spew out cosmic rays, which are high-energy particles that may create an experience similar to a nuclear explosion for those on the side of the Earth facing the explosion, causing radiation sickness.

To see how great a threat gamma-ray bursts might pose to Earth, researchers investigated how likely it was that such an explosion could have inflicted damage on the planet in the past.

Gamma-ray bursts are traditionally divided into two groups — long and short — depending on whether they last more or less than 2 seconds. Long gamma-ray bursts are associated with the deaths of massive stars, while short gamma-ray bursts are most likely caused by the mergers of neutron stars.

For the most part, long gamma-ray bursts happen in galaxies very different from the Milky Way — dwarf galaxies low in any element heavier than hydrogen and helium. Any long gamma-ray bursts in the Milky Way will likely be confined in regions of the galaxy that are similarly low in any element heavier than hydrogen and helium, the researchers said.

The scientists discovered the chance that a long gamma-ray burst could trigger mass extinctions on Earth was 50 percent in the past 500 million years, 60 percent in the past 1 billion years, and more than 90 percent in the past 5 billion years. For comparison, the solar system is about 4.6 billion years old.

Short gamma-ray bursts happen about five times more often than long ones. However, since these shorter bursts are weaker, the researchers found they had negligible life-threatening effects on Earth. They also calculated that gamma-ray bursts from galaxies outside the Milky Way probably pose no threat to Earth.

These findings suggest that a nearby gamma-ray burst may have caused one of the five greatest mass extinctions on Earth, such as the Ordovician extinction that occurred 440 million years ago. The Ordovician extinction was the earliest of the so-called Big Five extinction events, and is thought by many to be the second largest. [Wipe Out: History's Most Mysterious Extinctions]

The scientists also investigated the danger that gamma-ray bursts may pose for life elsewhere in the Milky Way. Stars are packed more densely together toward the center of the galaxy, meaning worlds there face a greater danger of gamma-ray bursts. Worlds in the region about 6,500 light-years around the Milky Way's core, where 25 percent of the galaxy's stars reside, faced more than a 95 percent chance of a lethal gamma-ray burst within the past billion years. The researchers suggest that life as it is known on Earth could survive with certainty only in the outskirts of the Milky Way, more than 32,600 light-years from the galactic core.

The researchers also explored the danger gamma-ray bursts could pose for the universe as a whole. They suggest that because of gamma-ray bursts, life as it is known on Earth might safely develop in only 10 percent of galaxies. They also suggest that such life could only have developed in the past 5 billion years. Before then, galaxies were smaller in size, and gamma-ray bursts were therefore always close enough to cause mass extinctions to any potentially life-harboring planets.

"This may be an explanation, or at least a partial one, to what is called the Fermi paradox or the 'Big Silence,'" said lead study author Tsvi Piran, a physicist at the Hebrew University in Jerusalem. "Why we haven't encountered advanced civilizations so far? The Milky Way galaxy is much older than the solar system and there was ample time and ample space — the number of planetary systems with conditions similar to Earth is huge — for life to develop elsewhere in the galaxy. So why we haven't encountered advanced civilizations so far?"
The answer to Fermi's paradox may be that gamma-ray bursts have struck many life-harboring planets. The most severe criticism of these estimates "is that we address life as we know it on Earth," Piran told Live Science. "One can imagine very different forms of life that are resilient to the relevant radiation."

Piran and his colleague, Raul Jimenez, detailed their findings online today (Dec. 5) in the journal Physical Review Letters.

For those who failed to actually listen and observe, the energy wave being spoken of in this report is the result of a pulse from a distant star, not our sun. It is from another
star in the galaxy. Big difference, not our sun as the source. So those who so quickly poo poo everything, please get your facts straight as far as your denials go. Not that long
to wait until it is proven or not. Meanwhile, eat drink and be merry, for your end is nigh, for your end is coming one day. None are immortal in body.

I'm curious... since I'm not an astronomer, wouldn't it take many, many years for a pulse to reach us? I mean, I don't know much about anything, but I thought that when we detect events that happen many millions of light years away, it happened way in the past. Right?
