Comment Re:People with artificial lenses can already see U (Score 1) 137

I hate black lights that are in line of sight. The entire bulb is a unfocusable blurry bright annoying thing. Even regular florescent light bulbs have an intense blue haze around them. I also hate it when there's overcast because many times the regular light is dim, so my pupils open more to let in the light so I can see, but the clouds are radiating a certain kind of "brightness" that makes my eyes hurt. Other people don't seem to notice it.

Dark Energy is just the least crazy idea. One of those reasons is that assuming our standard candles are still valid, objects are moving away from us faster than light, which is impossible with currently accepted solid theory. The only way to get this to happen is to allow space itself to expand, which is where Dark Energy comes in. Expanding space takes energy, a very calculatable amount.

If I had to choose between Dark Energy and expanding space or not expanding space and object moving through space faster than c, I'm going to go with Dark Energy until more information is discovered or the form of measurement of the expansion of space is invalidated.

Dark Energy is not a cheat, it is a placeholder. Assuming our measurements are correct, which the discussion of standard candles is challenging, some unknown source of energy is causing our Universe to expand, and that takes a lot of energy. It takes so much energy, that this energy needs to represent 80% of the Universe's total energy.

Unless you plan on challenging the First Law of Thermodynamics.

The Earth has gone through many phases and transitions have been deadly. What do you mean by "historical"? Which historical phase are we talking about? Around 20mil years ago, CO2s plummeted and was around 600ppm. For the past nearly 1mil years CO2 has remained under mostly 250ppm with brief peaks around 300ppm. In less than 100 years, we have gone from 300ppm to 400ppm, which typically took thousands of years. It is one of the quickest increases in CO2 concentrations for the past hundred million years or so, which the other ones were caused by catastrophic events.

I'm less concerned about the number and more concerned about the rate. normally these kinds changes take several magnitudes longer.

You sound like a Walmart shopper, looking only at the price tags. I first limit my search to 4 stars and above, then I look at what people say is good about the product, then I really dig in and look at what people hate about the product. If I see a bunch of 1 star reviews saying it breaks after several months of use, I'm going to go onto the next product.

I learn more from bad reviews than good ones, but I do use the average rating to limit the sheer number of options.
