View from Earth 100 trillion years in the future


Truly stunning video, from the Big Bang to the end of cosmology.

http://www.sciam.com/article.cfm?id=the-end-of-cosmology-video

Assuming the Earth is not consumed by the Sun during its Red Giant stage...
By 100 trillion years in the future, the Sun will have burned out long ago, and the Earth will have been ejected from the Solar system to wander as a rogue planet, alone in space. Due to the accelerating expansion of the universe, nearly all the galaxies recede from the Earth faster than the speed of light, and these galaxies are therefore no longer visible because their light cannot travel fast enough. At few of the nearest galaxies are still visible in the night sky in the illustration above, but they too will accelerate away, and the sky will become a black void for eternity.

Eventually, all of the matter making up the Earth will convert back to the energy from which it came, and all that will be left will be the void.

Great, unnerving audio effects

This is really great... and kinda creepy... you really need earphones.... and make sure the left earphone is in the left ear, and the right earphone is in the right ear.

Don't listen to this late at night... it is really creepy...

Life began... in ice?

This spectacular article the February 2008 Discover pulls all the pieces together, and after years of reading about all the bits and pieces, this smells right.

http://discovermagazine.com/2008/feb/did-life-evolve-in-ice

As I mentioned before, I think it is quite likely that we are not native to this planet. Life was probably seeded on Earth from Mars, or even from the ice moons of Jupiter or Saturn, because they were smaller and cooled more quickly than the Earth did. Asteroid and comet impacts then spewed huge amounts of material into space, and the archea cells were protected by the material and low temperatures in space. Life coming to Earth from another planet is called exogenesis.

As I mentioned before, I think it is also likely that we are not native to this star system. Life probably first arose on a planet billions of years ago in another star system, and material encasing archea cells was spewed throughout the entire galaxy long before the Earth formed. One or a few planets seeding the entirety of the galaxy is called panspermia.

So we can now sketch out the overall sequence.
After the Big Bang, the universe was mostly hydrogen and a little helium.
Stars formed and went supernova, producing the heavier elements. This process was repeated, and the amounts of heavier elements progressively increased.
Supernovas were more common toward the center of the galaxy, so there were more heavy elements toward the center of the galaxy.
On the other hand, if a supernova goes off nearby, it can easily sterilize the entire surface of a planet to a substantial depth, so being too near the center, while it would mean a lot of heavy elements would be present, would also mean that the surface would be sterilized fairly often. (However, now that we know how many archea live at great depths in the Earth, these sterilizations might actually present no problem at all.)
The Solar system is 4.5 billion years old, but we could easily imagine parts of the galaxy to have been rich in heavy elements 10 billion years ago.
So it is easy to imagine that on an ice planet in another star system 10 billion years ago, the processes described above in the Discover article took place, and the first archea cells formed and colonized the planet quickly.
Some cells were then blasted into space by impacts, encased in material that quickly cooled and protected the cells.
The materials spread across the galaxy relatively quickly, and some of it eventually landed on the ice moons of Jupiter and Saturn, and later, on a Mars covered by oceans, while the Earth was still molten.
The cells completely populated the moons and Mars.
Impacts on the ice moons and Mars ejected huge amounts of material into space, and some of it landed on Earth. If the Earth was still too hot, the cells would have died, but as soon as the Earth cooled so that there could be liquid water, the seeding would take place, and the cells then completely populated the Earth as it cooled.
So the processes described in the Discover article may actually have happened on another planet long before the Solar system formed. (And since our galaxy is made up of many smaller galaxies that have been incorporated into it, the origin of life may even have occurred in another galaxy.)
We may have good evidence for life on Mars in just a few months. In later missions, when samples are eventually returned from Mars and the DNA of the organisms is examined, if the DNA seems to be similar to that of the archea found on Earth, we could reasonably suppose that these cells had a common ancestor long before the Earth formed. That would be the greatest discovery of all time (so far) and would suggest that there are many planets in the galaxy with at least simple lifeforms... and that those lifeforms are all related... and that they are related to us.
We are on the verge of being able to detect Earthlike planets in other star systems.
Within the next few decades, we will have scanned a substantial part of the galaxy for other technical civilizations, so in our lifetimes, we will have either found another civilization, or we will begin to suspect that we are rare.

Here is part one of a program showing how life could be carried from planet to planet by impact debris.

Yellowstone is a supervolcano

Yellowstone is the caldera of a supervolcano. The last time it erupted 640,000 years ago, it was a good thing we weren't around... the US was uninhabitable and the rest of the planet was not good either.

Emergency Voice Mail from NTT East

When a major disaster, such as an earthquake occurs, NTT East may automatically block most calls in order to keep lines clear for responder services. When this happens, it is very likely that no one will be able to call you on your landline, and you may not be able to call other landlines in certain areas. Mobile phone calls may also be blocked in certain areas, although text messaging should always be possible.

So that you may let others know how you are, during such an emergency, voice mail can be created, and others can hear the voice mail by dialing your number.

The number to dial is 171.

Sometimes, the more you stare at a word, the stranger it looks

"Jamais vu" (French for "never [before] seen") means that a known object or situation (or even a person!) seems strangely unfamiliar or odd. "Jamais vu" is sort of the opposite of deja vu ("already seen").

When the object that seems strange is a word, this is called "word alienation". Most people can induce word alienation by, for example, simply staring at the word "and" for several minutes. Another way is to write, for example, the word "door", very quickly 30 times per minute for a minute or two. Most people will experience the word seeming to become progressively odd, and the more you stare, the stranger it looks.

In the usual course of reading, a word has a form, a meaning, and a function in a sentence, and they are experienced briefly; when the word is instead viewed repeatedly, only the form of the word is experienced, and the form becomes progressively dissociated from the meaning.
It seems that being tired or having worked many hours often increases the probability of word alienation occurring.

The question of convergence

For a long time, the question was: would TVs become computers, or would computers become TVs?

I've used my computer as a TV for years, watching DVDs and videos over the Net. In fact, I sometimes do not turn on my TV for weeks.

Now, TVs are starting to come with jacks for connection to the Net.

Maybe in the end both will happen.

How the elements were made

The early universe contained only hydrogen and a little helium. Where did the heavier elements come from?

Is this true? If so, millions of people in the UK now know about it.

The lead story at The Independent says that pigs are being shipped live from Canada to Hawaii so that the pigs can be sold as "island pork".

"Many live exports are undertaken to make the fraudulent claim that the animals are [locally] reared... Canadian pigs are condemned to a 4,500-mile journey by land and sea to Hawaii, so that, when slaughtered, their carcasses can be sold as "Island Produced Pork". For nine days, hundreds of pigs are crammed together in the dark, standing in their own excrement."

Click on the second video clip, entitled "Canada to Hawaii: Pigs transported for nine days".

February 12, 1809, and 1859

Next year will be Darwin's 200th birthday and the 150th anniversary of the publication of On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.

Over the next year, there will be many documentaries and special exhibits about Darwin and evolution.

The end of polaroids

Polaroid has announced that it is getting out of the film making business, so there has been a run on film.

Although I never had a Polaroid camera, someone was taking polaroids at a party on January 1, 2001, and I must admit, they were magical. Watching a picture appear over a few minutes is something that you simply cannot get from taking a picture with a digital camera. The suspense, the fun of watching how it turns out... and the usually very warm tones in the picture.

I knew a world with fewer printed books, printed magazines, and printed newspapers, a world without analog TV transmission, and a world without TV, was coming, but a world without polaroids would also be missing something, and that hadn't occurred to me until I saw this. At least click on the Polaroid Swinger commercial (if you are old enough, you will be humming it... and look who is in the commercial!) and the one with James Garner and Mariette Hartley below.

A newspaper discontinues paper version and goes Internet-only

In what is likely to be the first of many over the next few years, a newspaper has gone Internet-only.

GOD is coming

Coming soon: GOD (Googlelike Omniscient Databases)

In a very short while, you will basically be able to pose any question, and either someone will have already fully formulated the answer, or you will be able to get a general idea by looking through the databases yourself.

Although it is shut down now, last week, a company announced that it had gleaned the cell phone numbers of 90 million people in the US. If you wanted the private cell phone number of even a governor, just pay 15 bucks and they would give it to you. The numbers were obtained by searching through public documents.

Is a company doing a bad job? You will soon be able to ask questions about its problems, very specific questions. Considering reroofing? Why not look at a ranking of companies, they types of jobs they do, customer satisfaction, law suits, etc.?

Things like this, which previously required a human to notice, will be done automatically for the entirely of literature, scientific publications, news... and in all languages... very soon.

So, there really will be someone watching everything. That "someone" will be other humans who will soon be able to summon highly tailored information for free.
