This is another YTMND that I thought was interesting. Check it out.

Someone took The Enchantment Under the Sea Dance scene from "Back to the Future" and edited it to change the part where Marty goes nuts on the guitar. Instead of hearing what he originally plays, you hear the end of an intense song called "Through the Fire and Flames" by Dragonforce, an English power metal band.

I mean, this song is nuts! And to imagine Marty playing that instead… it's mind blowing. It makes perfect sense for Strickland to cover his ears.

I can only imagine how you'd feel if you were there living in 1955, and all of a sudden some psycho with a guitar loses it and plays something too wild to comprehend.

You might say, "He's in league with Lucifer!!"

I recently read at wired.com that things are getting cheaper and cheaper. Like at Yahoo — unlimited data storage in your mailbox. That's insane. That's awesome! Technology is advancing so far that most of the average user's needs can be met for next to nothing. And someday soon, it really will cost us all nothing! Well, that's the vibe I got from the article, anyway.

I wish Health Care and Education were free.

In Star Trek, I believe there is no need for money. I've never really investigated this issue, but from what I can tell, the reason for this is the presence of replicator technology. It's like every room has a microwave-sized box that receives voice commands. So you say, "Computer, please make me a ham sandwich." And I guess nanomachines go to work to quickly engineer your food item. Or maybe they use a combination of hologram/transporter technology to immediately convert energy into matter in whatever configuration is required. So instead of decompiling half-eaten ham dinners and stale bread, and then reassembling the components into a ham sandwich (or instead of breaking down sewage and using that to make the ham sandwich), the machine would simply convert pure energy into a fresh meal. Cool!

I think, though, that the closest we are to achieving replicator technology lands on the side of nanotech. This means that all garbage would become fuel. Kind of like at the end of "Back to the Future" when Doc says, "I need fuel!" and tosses an old beer can into the Mr. Fusion. But instead of using the atoms and molecules of the can and beer inside for fusion, the replicator would strip the paint/label from the can, file that away, break down the metal, store that, and probably filter or process the beer somehow. Then later, you'd say "Computer, make me a can of Coke," and it would use the old metal and maybe some of the liquid. Or, you could say, "Computer, make me some aluminum foil."

With replicator technology, we'd rely on factories far less. Some would put out replicators of various sizes, and then the upgraded model would arrive that was self-repairing, and could even make copies of itself. Certain groups or institutions might have room-sized replicators, or bigger. "Computer, make me a house!"

So everyone would have access to any item, any material they wanted. All you need is the raw materials, and if they can't be found in your garbage, you'd have to get them somehow.

That would cost, right? I don't think so. I figure if nanotech is that advanced, we could have mining crews of nanotech machines digging, finding, and saving raw materials. Maybe even in your own back yard. "Computer, dig up my yard, find me some stuff, then put it back like it was. Oh, and make my lawn look better than my neighbor's." And even if you said, "Computer, make me a diamond," but were out of coal, you could probably find some carbon elsewhere. Like maybe it could break down the carbon of that leftover fruit salad in your fridge. And then if you ever got sick of that diamond, or your wife left you for the robot she conned you into replicating, then you could say, "Computer, take this diamond and make me a fruit salad."

Fruit salad! Yummy, yummy!

So, with all that technology at everyone's disposal, most things would probably be free. Maybe not land, though, in the traditional sense. But I bet there are probably ways to "make" more.

Give everyone in the world their own microwave-sized replicator. That's an end to hunger. Maybe the box can pull water from the air. An end to thirst? And it can take sand and make a palace. So some guy out in the middle of the desert could probably survive with one of those boxes, even with no plants around. He could use his own waste to make more food, (clean of course), use the sand to make connectible tiles with which he could build a house, pull water from the air (or filter sea water)…

Why not just make a jetpack?

Or how about this? If nanotech in the box can make anything, why not have nanotech in the guy's body? The machines would smoothly convert his waste into further nutrients, rearranging all the bad stuff into stuff that serves a purpose.

Seriously, I heard that they're working on some kind of artificial blood. It's so efficient that if you had it inside you, you could sprint for 10 minutes straight…

…without taking a breath.

Sure, this stuff could be used to create super soldiers, or a replicating goo that could decimate a country (or the world, and that's a widely-acknowledged fear). But I think it's so powerful that it should probably eliminate the need for war. All we need to do is to think, and figure out how to fix the problems of the chronically upset.

Do you own a grandfather clock? I do. It’s neat. Functional and attractive. I remember hearing about a grandfather clock from a kids’ sci-fi story that had actual control over the flow of time. It was a cuckoo clock. So some kid climbs up on a chair and turns back a dial a few years. All of a sudden he’s three years younger! Crazy. I’ll bet someone who knew what they were doing could use that clock to wreak havoc with the stock market!

I was perusing 1-800-4clocks.com and I learned something. Did you know there’s such a thing as a Grandmother clock? I never knew that! Anyway, I found a pretty cool grandfather clock, cool because I’ve never seen one quite like it, and it seems almost futuristic. It’s a Kieninger Montauk grandfather clock, and it looks pretty modern, pretty up to date. If I had one of those, I think I might put it near the kitchen. Next to the dinner table maybe? Or perhaps in the dining room…

One thing I enjoy about 1-800-4clocks.com is that they have links to the sound each grandfather clock makes. That makes things so much easier!

I was reading their blog, and saw that clocks count in home design. That makes perfect sense, but I’d never really thought about it before. It does seem correct that certain clocks and grandfather clocks can really add a level of class and distinction to an otherwise ordinary room.

I never knew how huge a selection of clocks there is. I mean, at the site, even after getting specific and limiting the search to just grandfather clocks, you can still sort by maker. So getting even deeper into the world of clocks, selecting howard miller clocks, you’d expect there to be very few, right? But there are tons! And they all look great.

Someone with a decent budget could probably use this one site to build a replica of the opening scene of “Back to the Future.” Seriously.

Heroes is absolutely incredible. They have the option to make it complex, and they do so brilliantly. Monday, amnesiac Peter took his Irish gal pal for an unplanned trip to 2008, where over 90% of the world's population has been ravaged by disease. Peter and his lady are separated, and she is deported back to Ireland.

Then, Peter goes back to some other time, possible present-day, possible the time of the previous generation of heroes, Linderman's, generation. He meets Adam, the immortal samurai Hiro just made an enemy of, 400 years in the past.

All right, so the guy's immortal. That means all healers are immortal. That means Claire and Peter are immortal, and previous future Sylar was as well.

Back to the issue at hand. Peter left the future where "9 out of 10 dentists agree…that they're dead," but his girlfriend is still there! And you just know they're going to save the world again like they did at the end of Season 1. They stopped the bomb, and prevented the devastation and ensuing development of an anti-hero police-state. So they'll stop this disease too. But where does that leave Peter's lady?

In "Back to the Future 2," old man Biff in 2015 traveled back to 1955 giving his younger self a sports almanac with all the winners in every major sporting event for the next 45 years. 1955 Biff got rich. When Doc and Marty left 2015, they returned to 1985-prime, which was a Hell version of the time they once knew. Doc and Marty left Jennifer, Marty's GF, on a porch swing in 1985-prime. Then they went back to 1955, fixed history, and returned to the original 1985. There, they found Jennifer on the same porch swing.

How did that work? If Doc and Marty fixed the timeline in 1955, then the versions of them that were in 2015 a few days prior would have ended up back at the original 1985 to begin with, and would have brought Jennifer home and probably woken her up at some point. Like, "Here, your home now. Good night." How did she jump from 1985-prime to the normal 1985?

Well, anyway, if Heroes does that, and Peter never goes back for his GF (like that would happen), then she'll first show up in Ireland in the diseased 2008, having been missing for a few months. Then, Peter and co. will change history, cleaning up 2008. At that point, his GF will be in Ireland in the clean 2008. Or will she?

I think what could happen instead is that she randomly appears in clean 2008 at the time and place where she showed up with Peter in dirty 2008. She'd randomly appear in NY, and wouldn't be sent to Ireland because there wasn't any disease to mandate deportation. But does she show up without Peter? Hmm…

The way around this conundrum would be to have Peter go back to diseased '08 and bring GF back to 2007. I think they'll do that.

Alternatively, Peter and friends could first save the world, and then Peter goes to clean 2008, picks up GF, and returns with her to the present (by that point, the present would probably be the end of Season 2).

But man! I wish they'd explain what would happen if she were just left there, in a future soon to be rewritten. I'll bet there are a lot more interesting possibilities than what I've come up with.
