Why are you posting news articles that were written on November 6, 1997? 6586 days ago 941 weeks ago 216 months ago almost 20 years ago??? Sam Wormley wrote: > > Einstein was right - again!

Can you point to the link??? The truth is, there were no discussions on "frame-dragging" on this newsgroup or any other newsgroup on Usennet. So, Why are you posting news articles that were written on November 6, 1997? There has to be a explaination that true?

There has to be a explaination that true? Maybe you don't even know the answer to that question, even if you're the one who brought it up... I can understand that..there is a lot of that going on. So I'll ask you a simple question...Do you believe in flying saucers?

Dragging time is more important than space dragging.It will be used in the future as a time machine.Treb

All words in the 'scentific coounity' are vague so you can weasle out of it whenever yous want. You need to stay away from 'scientific' websites, they specialize in the unclear. fly·ing sau·cer a disk-shaped flying craft supposedly piloted by aliens: https://www.google.com/#q=define+flying+saucer In other words....an alien from another planet piloting a flying craft. Do you believe in flying saucers??? flying craft piloted by aliens

The question is not what speed flying saucers fly at, the question is.. Do you believe in flying saucers???

How did you manage to throw in the garbage in here?!? This is insane!!! I'm not talking about flying garbage, I'm talking about...flying saucers!!!! Okay, this alien thing is to much for you... I'll ask a simplier question... There is a God, or There is no God.. which do you believe?

Inertia will see to it that man is not capable of speeds close to c.I predict 22% of c is as fast as his frail body will allow.Robots like Treb are the only way to explore the vast universe.TreBert

From Wikipedia -- Cosmic Rays https://en.wikipedia.org/wiki/Cosmic_ray Cosmic rays are immensely high-energy radiation, mainly originating outside the Solar System. They may produce showers of secondary particles that penetrate and impact the Earth's atmosphere and sometimes even reach the surface. Composed primarily of high-energy protons and atomic nuclei, they are of mysterious origin. Data from the Fermi space telescope (2013) has been interpreted as evidence that a significant fraction of primary cosmic rays originate from the supernovae of massive stars. However, this is not thought to be their only source. Active galactic nuclei probably also produce cosmic rays. Track Cosmic Rays with Smartphone App http://www.scientificamerican.com/podcast/episode/track-cosmic-rays-with-smartphone-app/ Observing Ultra-High Energy Cosmic Rays with Smartphones http://arxiv.org/abs/1410.2895 Cosmic ray particle shower? There's an app for that. http://arstechnica.com/science/2014/10/cosmic-ray-particle-shower-theres-an-app-for-that/ Every second, the Earth is being struck by cosmic rays, high energy particles that slam into the atmosphere. Understanding where they come from and how they're generated could provide information about some of the most energetic processes in the Universe. But Earth's atmosphere protects us from them, ensuring that they don't make it to the surface. Instead, we have to look for the shower of photons and particles that the cosmic rays create when they hit the atmosphere. Even large detectors, however, only capture a few traces of the high energy particles that reach the Earth, meaning that careful studies of their origin can take years, possibly even decades. So some researchers decided it might be possible to take advantage of a large population of non-specialized detectors that are pre-positioned all over the world: cell phone cameras. The researchers from the University of California have drafted a paper in which they describe testing whether a smartphone camera can detect high energy photons and particles of the sort produced by cosmic rays. Testing with radioactive isotopes of radium, cobalt, and cesium showed that the detector easily picked up gamma rays (and you didn't even have to point the phones at the source!). They also put a phone inside a lead box and showed that they could detect high energy particles. Finally, they took a phone up on a commercial flight and were able to obtain a particle track across the detector. -- sci.physics is an unmoderated newsgroup dedicated to the discussion of physics, news from the physics community, and physics-related social issues.
