3/Three Ways Parents are Ruining Halloween

Sagemind says...

Pssst... Did you mean "PRE" Halloween sale... since it's not Halloween yt, and time travel has not been invented....?

Re: the too scary thing... I CAN see that. Yesterday I was at a post-Halloween sale.

One-Minute Time Machine

When she presses the button, are we to assume she's the one dying in those alternate universes? If so, wouldn't he then also press the button, leaving behind even more dead versions of himself?

So only copies of yourself ever get to experience what feels like time travel. All those first attempts look like complete failures leading to death. Bummer.

Project Almanac Time Travel and the Butterfly Effect

Just rented this last week.

It's interesting to watch as a semi-reality-based time travel movie, but definitely has some nonsensical and wtf aspects to it (such as the ending).

Is Climate Change Just A Lot Of Hot Air?

newtboy says...

OK
#1. Your study quote which said no mechanism had been discovered.
#2. "but the drivers, magnitude, timing and location of methane consumption rates in High Arctic ecosystems are unclear."...LOCATION UNCLEAR MEANS NOT FOUND.
#3...this does not make sense, "this feedback will be moderate: of a magnitude similar to other climate–terrestrial ecosystem feedbacks" is self contradictory, since many terrestrial ecosystem feedbacks are NOT moderate...depending on the definition of "moderate". If less than 10 deg C is moderate, then they're right.
#4. You can tell them 98%+ of scientists in the field of climatology say side effects of industry/technology will cause "X" at a minimum in 100 years, and it has already caused "Y" (warming, weather changes, ocean acidification, environmental pollution, rising cancer rates, water shortages, other indisputable factors), send him back with proof of those effects, and I think same result..."no thanks".

I misunderstood I guess. If you did that, he would just be in a rubber room for claiming to be a time traveler, not seen as a visionary. ;-) If he could offer proof of the time travel, the state of the planet, and the environmental trends showing every issue is seemingly getting worse leading to cluster f*ck, it would not be a hard sell in the least, IMO. At least not to people with an IQ over 90. You don't have to abandon all those things (coal, yes), you would just have to design them better. Electric cars were often the norm before Ford in towns. Planes might be electric dirigibles, and satellites might be put in orbit by rail guns.
If you don't think 1/3 of the planet's population (a reasonable guess if water shortages continue the current trend) being migrant doesn't warrant 'panic' (which I never suggested, I will say it warrants concern even by those in the '1st' world) then I don't know what to tell you.

@newtboy,

How about great big citation needed. Your making a lot of assertions and about zero references to back anything, your just one step shy of claiming because I say so as your proof.

The rotting material creates exponentially more methane than any mechanism could trap.
Citation required.

your study quote did not say that "they've identified regions up north where the soil absorbs more methane the warmer it gets
The abstract is only a paragraph and the charliem gave the link up thread, just go and read it already, they did numerical estimates AFTER going in and directly measuring the actual affects. And I must additionally add, it's not MY link but was instead the ONLY claimed evidence in thread of your catastrophic methane release.

Let me start us off, the IPCC once again summarizes your problem as follows:
However modelling studies and expert judgment indicate that CH4 and CO2 emissions will increase under Arctic warming, and that they will provide a positive climate feedback. Over centuries, this feedback will be moderate: of a magnitude similar to other climate–terrestrial ecosystem feedbacks
http://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_Chapter06_FINAL.pdf
From FAQ 6.1

There are caveats prior to the above quote about unknowns and uncertainty and the possibility the affects will be less or more, but the consensus is, don't panic. Like I said.

As for bringing that person from 1915 in today, you don't get to tell them the environment will be destroyed 100 years from 2015 in the year 2100 as a result. You have to prove that first, which you have merely asserted, not proven. On the other hand, my evidence was bringing our visitor from the past showing them the year 2015, and the consequences of rising global temperatures by 0.8C since his time in 1915. Then I say we ask him if abandoning coal power, airplanes, satellites, and cars to prevent that warming is a better alternate future he should go back and sell the people of 1915 on. I'm thinking that's gonna be a hard sell. I'm additionally pointing out that the IPCC projections for the next 100 years is 1.5C warmer than today, so we'll be going up by 1.5 instead of the 0.8 our visitor from the past had to choose. The trick is, I don't see how you can claim that panic should be the natural and clear response. You need a lot more evidence, which as stated above you've failed to provide, and more over what you've posited is contrary to the science as presented by researchers like those at the IPCC.

It may be unfishable in 15-20 years at current acidification rates.
citation needed.

by 2025 it's estimated that 2/3 of people worldwide will live in a water shortage.
citation needed, and you need to tie it to human CO2 and not human guns and violence creating the misery.

The downvote was not for your opinion, it was for your dangerously mistaken estimations and conclusions...
, says you. If you don't use any evidence to refute me it's still called your opinion...

eoe, thanks for the recommendation. I just finished watching Predestination and adored it. Good call. Truly a great time travel movie. Cheers!

eoe said:

I nominate Predestination as a contemporary, really good (and slightly fucked up) time-travel movie.

Yeah, it has Ethan Hawke, which might turn some off. But is very, very good.

One of the best movies I've seen in a while.

Watch it cold. Don't read anything about it.

Just once, one time, I'd like to see a time travel movie done properly... ok the Time Traveler's Wife was done right, but there were no guns and shit, so...

Interstellar - Honest Trailers

dannym3141 says...

I enjoyed it. I don't understand many of the criticisms - it's a film, were we somehow expecting to have our humanity validated by it? A scientifically accurate description of a mission would be boring - they'd almost certainly die in the wormhole.

The science wasn't unreasonable. It was a lot closer to reality than anything in star trek or star wars. Anne Hathaway's character muses on the power of love and suddenly it's a force of the universe? My memory might be flawed, but i don't remember hearing anyone confirm that or discuss it - in fact, the state her "lover" was in was kind of contrary to the opinion she gave and certainty to how she felt. We really do have no idea about black holes, either, so for all we know it could be manipulated by some future technology. The tesseract "library" was an interesting take on time travel/time manipulation.

The only thing that broke my suspension of disbelief was the bit when they said they thought they had years of good readings from the water planet due to time dilation. But that doesn't make any sense, because the number of signal pulses sent from the surface must equal the number of signal pulses received in orbit. My best guess is that the pulses would be elongated and have their wavelength shifted, possibly, but one thing i am certain of is that the total number can't be different.

The problem is, the older you get, the more you know about science, the less faith you have to put in films to give you a mind-bending experience that works on so many levels. None of it is plausible, so why rule it out based on what Hathaway thinks about the nature of love, or anything else?

Good film! And funny video. Someone's got to defend it though!

Can we bring back Quantum Leap instead? Time travel within your own lifetime genre is overdo. Put Arnold in it. Make him sing Imagine.
