the planets got bombed the fuck out of
at a certain stage in the solar system

enough so that part of them got ripped up and off
thrown into space
and landed on all the other planets

we got as much chance of finding ourselves on mars as anything

just in case anyone thought I was crazy when I pointed this out a couple of years ago...
they're finally now admitting how close we really came... see how they are?
always in denial to the public, until it's old news.

Earth survived near-miss from 2012 solar storm: NASA

AFP
8 hours ago

Washington (AFP) - Back in 2012, the Sun erupted with a powerful solar storm that just missed the Earth but was big enough to "knock modern civilization back to the 18th century," NASA said.

The extreme space weather that tore through Earth's orbit on July 23, 2012, was the most powerful in 150 years, according to a statement posted on the US space agency website Wednesday.

However, few Earthlings had any idea what was going on.

"If the eruption had occurred only one week earlier, Earth would have been in the line of fire," said Daniel Baker, professor of atmospheric and space physics at the University of Colorado.

Instead the storm cloud hit the STEREO-A spacecraft, a solar observatory that is "almost ideally equipped to measure the parameters of such an event," NASA said.

Scientists have analyzed the treasure trove of data it collected and concluded that it would have been comparable to the largest known space storm in 1859, known as the Carrington event.

It also would have been twice as bad as the 1989 solar storm that knocked out power across Quebec, scientists said.

"I have come away from our recent studies more convinced than ever that Earth and its inhabitants were incredibly fortunate that the 2012 eruption happened when it did," said Baker.

The National Academy of Sciences has said the economic impact of a storm like the one in 1859 could cost the modern economy more than two trillion dollars and cause damage that might take years to repair.

Experts say solar storms can cause widespread power blackouts, disabling everything from radio to GPS communications to water supplies -- most of which rely on electric pumps.

They begin with an explosion on the Sun's surface, known as a solar flare, sending X-rays and extreme UV radiation toward Earth at light speed.

Hours later, energetic particles follow and these electrons and protons can electrify satellites and damage their electronics.

Next are the coronal mass ejections, billion-ton clouds of magnetized plasma that take a day or more to cross the Sun-Earth divide.

These are often deflected by Earth's magnetic shield, but a direct hit could be devastating.

There is a 12 percent chance of a super solar storm the size of the Carrington event hitting Earth in the next 10 years, according to physicist Pete Riley, who published a paper in the journal Space Weather earlier this year on the topic.

His research was based on an analysis of solar storm records going back 50 years.

"Initially, I was quite surprised that the odds were so high, but the statistics appear to be correct," said Riley.

"It is a sobering figure."

but do you think they'll ever admit that this wasn't just a jet contrail off the coast of california in 2010? I was really disappointed in Michio Kaku for saying that.

those events are crazy
go boiling off into space

we as a society depend on infrastructure
that will be taken out and down for YEARS when hits us

Of course, had NASA not bothered to place solar listening stations around the Sun, we never would have known quite how serious the CMEs were.

nobody said that!

we said the aspects which take up the lions share of the efforts and expenditures are a boondoggle ANYTIME
given if we hadnt bothered with the manned stuff we would have had that system up and running 20 years earlier


heres a wild one

NASA confirms "impossible drive" actually works


it was proposed in 2003 and the inventor was laughed out of the rooom
as the design seemed to violate the law of conservation of momentum

in 2009 the chinese said they had built one and confirmed the principal but it wasnt believed

the design uses electricity to bounce microwaves around a chamber which someone produces thrust

that means this engine will never run out of fuel in space

Ahhh it seems this em-drive tech has some real scientific credibility issues.
Actually it's a multitude of issues that in the end add up to a consistency and repeat-ability issues:

1) Different devices of the supposed same construction producing different results
2) The same device with changing results over time (that Woodward ascribes to heat relaxation changing harmonics of the capacitor/piezo crystal.)
3) None of the devices giving a straight-forward 'as predicted' thrust. Observed results were always different then predicted numbers.
4) Inability to scale up the results despite supposedly understanding what is required to do so.
5) No peer-reviewed publications on the subject had been made.
6) After going through an expensive and lengthy session to get the necessary vacuum chamber to run the experiment in, they left the door open cause the capacitors in an amplifier wouldn't work in a vacuum. Introducing heat vibration problems in a non vacuum.

And from the NASA paper:
one visible effect to the seismic environment is the periodic (about one-third to one-quarter Hertz) perturbation created by the waves from the Gulf of Mexico (about 25 miles southeast of Johnson Space Center), especially on windy days.
The thrust they're measuring is so small that waves in the ocean 25 miles away could screw up the experiment! They tried to deal with this... but it goes to show, you can't revolutionize physics until you carefully check all the sources of error.



Anyone remember LERN and NASA hype over it too?

obviously you know zilch about space travel

the ion engine was a revolution 30 years ago as it came online
it produced thrust equivlant to a paperclip falling on the floor and it revolutionized thrusters

youd have been one of those guys who watched the film of the wright brothers flight
then pointed out all the aspects in which is wasnt like a bird

therefore they didnt fly

jeez

Ahh surely ya must know i DO understand about near frictionless momentum. I did take kinematics 101.

My post was not about the feasibility as a space drive, that would be great if it works.
Even with the micro newtons the theory predicted in the experiments. So small of a force that ocean waves 25 miles away measure comparable thrust. That is umpteen magnitudes smaller then a paperclip falling in one G.

But my concern is with the science.
None of the experiments have given consistent and duplicable results. Two tenets you gotta have for the scientific method.

The theory seems sound to me, but dont know enough to challenge it.
But the experiments do NOT give the predicted results, leaving the theory on how it works suspect. Even NASA's experimental test control that was not to produce any thrust, did! Red flag to any researcher worth their salt.

that means this engine will never run out of fuel in space
not quite, one still need to carry a generator to create and control the Electro-magnetic (EM) field

Within mars orbit solar panels theoretical with today’s tech would work, I think. but the outer planets and beyond a fission motor is more in order. Or something that will generate an EMF for the EMdrive. There is still fuel to carry, just not the bulky reaction mass.

Also a correction, I meant LENR, not LERN in my post above. Low energy nuclear reactions. Cold fusion. Nasa ran experiments producing an anomalous energy spike, hyped it up and then nothing else heard.
