Dark Energy really is an Energy, not a different behaviour of Gravity
Well, I'm not sure I believe these findings, it seems rather tenuous to
me. I don't see a strong proof against gravity (or rather anti-gravity) here. But anyways, all sides need to be heard to make a decision. Yousuf Khan *** Dark energy is real, new evidence indicates - Technology & science - Space - Space.com - msnbc.com " A census of 200,000 galaxies may confirm that the mysterious force of dark energy is what is pulling the universe apart at ever-increasing speeds, a new study finds. The results of the five-year galactic survey offer new support for the favored theory of how elusive dark energy works — as a constant force, uniformly affecting the universe and driving its runaway expansion. The new findings contradict an alternate theory that gravity, and not dark energy, is the force pushing space apart and causing it to expand. That alternate theory challenges Albert Einstein's concept of gravity, because it has gravity acting at great distances as a repulsive force rather than an attractive one. The galaxy survey, which looked at galaxies that were up to 7 billion years old, used data from NASA's space-based Galaxy Evolution Explorer (GALEX) and the Anglo-Australian Telescope on Siding Spring Mountain in Australia.

But anyways, all sides need to be heard to make a decision. This reads more like a repetition of a well known result using something other than Type 1a SN's rather than a radical new observation. It'd help if they linked the actual paper or something, so people with an education in the subject can read it w/o the lens of a broad audience level writer. [...] |

Dark Energy really is an Energy, not a different behaviour ofGravity
There are alternative theories to GR out there where the non-science dark
matter & dark energy hypothesis are not needed. It would be a better use of the funds to quit looking for invisible stuff (a hypothesis that cannot be falsified) and to determine which of the alternative theories is correct. |

Now dark matter is filtering into my imagination. I'll try looking for that next. Should I look into the vacuum of space? TreBert There are several theories for what Dark Energy really is. One theory is that it's Einstein's Cosmological Constant -- well, not really Einstein's version, because Einstein introduced it as a way to explain a static unchanging universe (which was the assumption during his early days), whereas the version we are talking about here is to explain an expanding accelerating universe: i.e. the Cosmological Constant is used as a force for change rather than Einstein's force for no change. The only problem with the Cosmological Constant is that there is no explanation for where it comes from, plus as its name implies, the force is constant over time, right from the beginning of time it was there in some form. Another theory for Dark Energy is called Quintessence. Quintessence also involves an energy set in motion within the universe from the early days. The difference between this and the Cosmological Constant is that it's not constant throughout the history of the universe. Quintessence evolves and gets triggered at some point in time. According to the theorists behind Quintessence, it gets triggered 10 billion years ago, at a moment in time when matter begins to dominate the universe over radiation. Because this energy is non-constant, it allows for atoms to form, and then for stars and galaxies to form without being blown apart by Dark Energy right away. Still no explanation of what this energy field is made of. Then there are theories about what this energy field is made of. The most popular, and probably the only theory for this right now is that it's made of the Quantum Mechanical Vacuum Energy. The only problem with QMVE is that QMVE is 120 orders of magnitude *too* large to explain Dark Energy. So now the work continues on how to explain why only a miniscule portion of QMVE is being used to drive the whole universe apart, rather than all of it. Basically it's a matter of massaging Quantum Theory through its loopholes. Yousuf Khan |
