Astronomy Cast Ep. 398 – Seeing Things: Emitting, Reflecting, Ionizing Light Sources

Astronomers gather electromagnetic radiation with the telescopes: mostly visible light. But sometimes they’ve got to be clever about where they look for these elusive photons. Light can get emitted, absorbed, reflected, and each method tells astronomers a little more about what they’re looking at.

Just something to think about: If something can happen in a lab, it probably already happened naturally in the Universe. Einstein was a genius. The famous solution to a calculus problem. E=mc^2. Where in the Universe does that occur naturally? Fission or fusion doesn’t quite hit the spot. But where can you find mass literally traveling at the speed of light squared to spontaneously convert to energy? It will happen. It happened before too. It has always happened. Think of the Big Bang. What caused it? Hint: E=mc^2. The expansion of the Universe many trillions of years from now. The Universe is accelerating apart faster than the speed of light. The expansion no longer can be measured at… Read more »

None of this has been proven and is only mathematical conjecture. The same goes for the entire gravity based concepts called the “‘standard model”. The newest radio telescope data seems to contradict all of the current models especially “black holes” and dark matter/dark energy”. These mathematical constructs have never been observed or experimentally confirmed. I find it astounding that this fact is routinely overlooked. Black holes are certainly not holes and are not black either. They have been observed to emit massive amounts of electromagnetic radiation including plasma jets and gamma radiation. They also are surrounded by massive magnetic fields which presumes massive electric current within. These galactic centers are most likely super dense, rapidly rotating plasmoids. This… Read more »

“This makes sense since electromagnetic forces are 10 to the 39th times more powerful than gravity.”

*slurp* That’s great until one remembers that the EM force decays over distance by (at least) an order of magnitude greater than gravity does. The net result is that at cosmic distances, EM truly becomes the “electro-WEAK” force, haha! *slurp*

“Only those with knowledge of plasma physics and electrical engineering will be able to make sound scientific conclusions.”

*slurp* Do you mean, the same electrical engineers (not to say “high school physics students”) that can use Coulomb’s Law (see above) to shred your Electric Universe theory without so much as putting down their coffee mug between sips? *slurp*
