useless spending in our govt should be scrapped and put towards usefull goals like trying to grasp facts that effect our world as a whole and not just imaginary lines and greed-wars. we all live on this rock together.....dont we

If Dark energy takes up 75% of the universe, where is it? And how can we tell it's even there?

Ender

How I understand it is that dark energy is somewhat like the cosmic backround radiation. When all the material of this universe came into being during the big bang (supposedly) and cooled in the first few seconds, a lot of photons were released into the ether of space before any of the protons or electrons, so we are all bathed with these dark aged photons. We can also see evidence of dark energy by the way galaxies are moving apart in the universe. For the amount of mass that we do see in the galaxies, their motion does not fit the mathematical problems. So the astronomers tweak the equations and add more mass and energy, dark matter and dark energy. So what these things really are are screw ups in the equations, where the scientists make the equation fit to our natural environment.
And as for completely shutting down and programs in the US that do this type of research, why? So what if we have millions of dollars being spent in astro-physics research, because of it we are closer to fusion, if dark energy is ever understood we could have another source of cheap, clean energy. And before you start criticizing the space programs just know that the US prison system gets 10 X more funding then the US education system. Don't take away from scientific research, fight against spending millions of dollars a day for a war in Iraq, or the injustice of tax breaks for the extremelly rich, but not space.

Dark energy. It's where all human waste goes, fecal matter. The 90 percent of the universe that's missing is dark brown shit from human rectums.

Dark energy is nothing supernatural. I'm sure the explanation for dark energy is nothing that would boggle our minds in the least. The universe unfortunately came up empty. It's worst case scenario, random chaos. There's no Supreme Being that created it and sits back and watches but never intervenes. Physicist Richard Feynman had a great quote on how life began on this planet and how infinitesimal the chances are that it exists anywhere else in the universe, even microbial life: "It's like a tornado going through a junkyard and assembling a 747."

Is dark energy , just enrgy we can't measure; For instance lets take radio waves; if we had no radio attennas to measure this long wavelength energy would it just be part of the dark energy mystery? What if the longest wavelength of light just doesnot stop at 3 meters, what if the longest wavelength of light can be 100 meters, even 1000 meters, even a light year. Okay, maybe theire would be a qquantum limit. [ energy of light is planks constant X c/ wavelength. what is the minmum, why does their need to bwe a minimum.
vibrations ; angular momentum; all could generate electromagentic fields which could be manipulated into light. In the pass we have called this the ether of space , the pressure of space ushing upon itself, what if this is just a wavelength of light that is too long to measure accurately, thus it is dark unto us.

Throughout recorded history, several cosmologies and cosmogonies have been proposed to account for observations of the Universe. The earliest quantitative geocentric models were developed by the ancient Greeks, who proposed that the Universe possesses infinite space and has existed eternally, but contains a single set of concentric spheres of finite size – corresponding to the fixed stars, the Sun and various planets – rotating about a spherical but unmoving Earth. Over the centuries, more precise observations and improved theories of gravity led to Copernicus's heliocentric model and the Newtonian model of the Solar System, respectively. Further improvements in astronomy led to the realization that the Solar System is embedded in a galaxy composed of millions of stars, the Milky Way, and that other galaxies exist outside it, as far as astronomical instruments can reach.

This is such a fabulously intriguing idea, these books that will never be written. And now I so want to read them all, mostly due to your skill with evocative covers. I look at them and feel the story within. Or the story that could be within. I'm not sure if I should thank you or curse you...

I can't believe how much of this I just wasn't aware of. Thank you for bringing more information to this topic for me. I'm truly grateful and really impressed.
