We live in very interesting times

[lompocus]

Hey, why don't I add a few non-political things to the tech/science shortlist:
-Cheap commercial space travel; widely accessible across globe (because, on occasion, cheap and accessible are not mutual... brain is gone today, I am afraid...)
-Personal computers as fast as the most powerful modern super computer (you'll have to look the numbers up, I'm afraid...). Must be affordable and accessible, i.e. your grandmother will have one.*
-permanent habitation on Mars, the Moon, or a station in lunar orbit (where permanent implies just that, permanence in the sense of life/death in orbit or on a non-earth planet).
-Some form of (again, cheap & accessible) life extension.

All of this by that same deadline of 2070.

*Your grandmother may not be alive; however, I hope you understand my meaning!

To go to war, a majority of citizens of country X must believe that the people in country Y are evil, and the only way to deal with them is to kill them. Globalization and the internet make it very difficult to isolate a country enough to effectively do that, IMO.

Imo, it may come down to energy - it is pretty hard to sell world peace when fuel hits $10 [or $20] a gallon - but I think the internet and trade do offer the real hope that war as we have known it will finally end.

On the flip side, the internet has helped to radicalize individuals and groups that would otherwise just be nuts. I am reminded of the movie, Brazil, which portrays a world where terror attacks are just an everyday event that hardly anyone notices.

Regarding life extension, while I would regard this as a fringe claim, I have heard experts in the field claim that, in the lifetime of a young person today, life could be extended to 200-400 years. The claim is that advances in this field will simply outpace the aging process. So through one advancement you may get, in effect, an extra twenty years, and before you get too old, another advance comes along and you will get another twenty, and then another forty, and so on.

With that in mind, today's news.

Researchers at Harvard-affiliated medical centers genetically manipulated mice to age faster, and then used gene therapy to lengthen telomeres -- compounds found at the ends of strands of DNA -- which reversed age-related problems such as decreased brain function and infertility...

http://abcnews.go.com/Health/Alzheimers/aging-reversed-mice/story?id=12269125

emphasis mine

About twelve years ago on a long flight, I met a person from Harvard doing telomere research. He too thought 200+ year lifespans were entirely possible in the relatively near future [decades].

Also, hopefully, paralysis, blindness, deafness, lost limbs, and other similar human conditions will be a thing of the past. There is a real possibility that we will one day have the medical technology to regrow lost limbs and correct the other problems.

We had better develop sustainable solutions for farming, our energy needs, and our desired rate of consumption.

Beat the crowd and practice birth control now!

5. "irrefutable evidence" of a habitable planet

> 90%

 

[BobG]

Let's give this thread some teeth.



Suppose you were in a betting mood. What odds would you place on each of these events?
1. Third World War
2. Second American Revolution
3. First female President of the US
4. First person walks on Mars
5. "Irrefutable evidence" of a habitable planet
6. ET life discovered
7. Palin elected President of the US
8. World epidemic
by, let's say, 2070 (since I don't know your age).

1. Almost 100%. However, it won't be the nuclear holocaust most people imagine. It will take place in the Middle East South Asia and will be more devastating than World War II (especially the disruptions to oil supplies), and may well include some nuclear weapons, but it won't be the end of the world.

2. Almost 0%. This is counter-intuitive. The chances of a country with such a large diversity of ethnic and religious groups avoiding civil war should be very small, but we seem to have hit on a system that finds a way to eventually incorporate everyone into the mix.

3. 85%. I don't think Clinton was a good choice as the first serious female candidate, but there's too many good female candidates available for this to be more than a matter of time. The only thing pulling the percentage down so low is that elections only take place every 4 years, the number of 2 term Presidents, and that there will probably be more male candidates than female candidates for some time.

4. Maybe about 1%. This is an expensive undertaking that needs an artificial reason to provide the necessary motivation. It just doesn't have a good cost-benefit ratio on its own.

5. Almost 100%. We keep getting better at detecting smaller planets and technology is the only limiting factor.

6. 1% to 2%. Our detection of ET life will be detecting intelligent signals from space. Signal strength is inversely proportional to the square of the distance between the source and us, there's a lot of space to survey, meaning the odds of finding a signal soon are very low, even if the event itself should be inevitable.

7. 2%. TV and movies have a big impact on our lives. Fred Thompson was a leading Republican contender last election (but at least he actually had some political experience prior to becoming an actor). I think there's at least a small chance of getting one really bad President from the entertainment field before people realize politics is a serious business. (And, in spite of Palin being a former governor, I do consider her more of a celebrity candidate than a serious politician.)

8. Depends more on the definition than anything else. Technically, this is a 100% probability. If you start placing limits, say wiping out 20% of the world's population, then the chances go down significantly. If you start placing limits such as an epidemic wiping out a high percentage of the industrial world, then the probability approaches zero. (I think an epidemic that wipes out 300,000 people in the US would be a pretty bad epidemic - that would wipe out 0.1% of the US population.)

2. Second American Revolution <1%

We seem to have a "revolution" every 8 to 12 years, don't we? If you mean with guns, etc, I doubt that anything larger than a few pockets of out-of-hand militias will be skirmishing. I believe our strongest asset is the dedication of our military forces to the constitution and the concept of the United States. My father is a retired Navy Captain, and I live in a Navy-dominant area and so I know that the predominant ideology of our military officers is not superficial adherence to the word of anyone person, but to the welfare of the Union.

All those militias are weak farts in comparison to the force and fortitude of our trained military. I would put more trust in the worst academy-educated officer than the "best" guy any populist militia has to offer (grain of salt: OK, some officers might have gone "over the edge," so I'm referring to any officer the military deems to be fit).

Regarding the OP, yes we do live in interesting times, don't we? I look forward to the second-half of my life (here's hoping) with apprehension and excitement. I'm intrigued by how we shall deal with the loss of cheap oil (please note I said loss of "cheap" oil; there's plenty of it, it just won't be cheap anymore). Which way will we go? Will we get hydrogen fusion figured out, or will we just burn everything?

 

[Mathnomalous]

The future scarcity of cheap oil is a very minor issue to me; we already have decent solutions in place, like wind and solar, and once cheap oil becomes very expensive, few people will object to those others types of electricity generation.

I am just disillusioned with the current state of the world; my generation lacks grand motivations, grand achievements; we got nothing to be proud of. The Founding Fathers decided that writing letters to kings was a waste of time and started a Revolution; in the 1940s your parents kicked the crap out of the Nazis; you and your cohorts put people on the moon and later on brought down the USSR via containment. Our greatest "achievement", so far? Facebook and World of Warcraft...

We need motivation; we also need a goal, a big objective. Maybe rebelling against the current system or sending someone to Mars; perhaps the discovery of a habitable planet will spark something in us. It is bound to happen, right?

 

[discrete*]

Looks like we may get an answer to the habitable planet question much earlier than we may have thought. Just speculation, but it seems like NASA has quite a statement to make. See this link: http://www.nasa.gov/home/hqnews/2010/nov/HQ_M10-167_Astrobiology.html

 

[mheslep]

Based on data from the COW project I count 321 wars starting 1992-2001 (since 2001 is the most recent year with data). Modeling this as a Poisson process, I estimate the probability of having no wars over a given 60-year span at exp(-32.1 * 60) or about one in 3 x 10⁸³⁶.

All of which are very different from world wars.

 

[Andre]

Taking the bait too

1. Third World War

Very remote, Lisab tells exactly why, but in addition, there is no fuel to be waisted to such a luxury. Better stick to your local sport/tribe wars.

2. Second American Revolution

Rather likely, no place on Earth where two opposite groups polarize so quickly due to the herd instinct/groupthink.

3. First female President of the US

Pass, no idea, may the enlightment conquer Jesus land.

4. First person walks on Mars

Forget it, there is no 'Kennedy challenge and we have some economical issues to solve

5. "Irrefutable evidence" of a habitable planet

Infinitisemally small. As I have shown on numerous occasions, Earth may be needing the moon for a stable rotation which is required for stable climates and conditions. This is not incorporated in the Drake equation, so even if you find 100 planets in the goldilox zone with all favorite conditions; if none has a sizable moon, they all may just look like Venus.

6. ET life discovered

See previous

7. Palin elected President of the US

yeah right.

8. World epidemic

Just slightly above unlikely as Earth population gets more dense.

 

[mheslep]

Just out of curiosity, why does everyone seem to think a third world war is so unlikely?

post 20

No full fledged democracy has attacked another since Athens attacked Syracuse. Now there are some 160 democracies.

Exactly. The other great rarity as I understand stems from the apparent finding that a planet forming at the required life supporting distance from a star does not gather water (or its elements), and the Earth likely got lucky by picking up water from post formation collisions with outer solar system objects, which in turn were disrupted by another freak accident in the outer solar system. Then there's the detection technology issue. Seems to me direct spectrographic inspection of an Earth sized plant is required, for which the indirect methods of star wobble and star intensity dips on planet passes will not suffice, and has not even a remote possibility of success more than a few hundred LY out. But then, what do I know.

 

[Ivan Seeking]

The future scarcity of cheap oil is a very minor issue to me; we already have decent solutions in place, like wind and solar, and once cheap oil becomes very expensive, few people will object to those others types of electricity generation.

There are currently no viable options to replace our oil supply. There isn't enough wind to solve the problem [not by a long shot]. Solar is coming along, but until we see battery-powered trucks, trains, and aircraft [all but impossible right now], and solar cells that are dramatically cheaper than they are now, we don't have a solution. Electric cars aren't competitive yet and may never be completely.

I see this as one of the most important issues that we [the world] face. Imo, alternative fuels that can replace oil are hypercritical to our future. [I should say your future, not mine. I'm getting old. ]

Why are the chances of a planet having a moon "infinitesimally small"? Every planet in our solar system has moons [less Mercury? I forget]. And we know that one out of eight had the conditions necessary for life to evolve.

And this is all highly unlikely in other systems? Why? What you call a freak accident, I call all but inevitable given enough time.

 

[Mathnomalous]

Ok, so the future is crap and the great things many people daydream about are not likely to happen. Can we at least get some big rock to swoop by Earth or something..? There has to be something "sexier" than running low on cheap oil out there!

I demand more carrots on sticks!

Some day, we'll have meat on a stick. That's when we'll know we have it made.

Gee, when I was little everything that could be discovered had been, man's dream of reaching the moon, been there, done that, man's dream of flying, same. Man's dream of transmitting sound and pictures around the world? Flameless light? Cooking food in a cold box?

Yeah, we should have all just dug our heads in the sand and given up, what else could there be to do that we hadn't already done?

 

[Andre]

the keyword is "sizeable", the moon has to be big enough to have enough gravitational influence to cause the precession cycle to be much faster than the tilt cycle. If those cycles get into resonance eventually, the planet gets into the "chaotic zone" according to Laskar (same link).

Venus has no moons either. Furthermore the ratio of the moons masses versus planets masses is by far the biggest for the Earth/moon combination

Mmm...chicken satay...I could go for some Thai...

I don't think we have enough statistical data to properly gauge the rarity of a moon of the proper size and orbit... but it does seem to me that our own solar system tends to show that moons (in general) are a fairly common occurence.

Furthermore the ratio of the moons masses versus planets masses is by far the biggest for the Earth/moon combination

Not true, Pluto/Charon is a much larger ratio. Mass wise, Earth/Moon is about 81, where as Pluto/Charon is 8.6.

 

[Grep]

Note that he said planets.

*Runs for cover*

 

[Mech_Engineer]

*Runs for cover*

Be that as it may, it seems to me that a claim of planet/moon mass ratios similar to Earth's being rare is unfounded. Furthermore, the presence of a "dwarf planet" with such a large planet/moon mass ratio (10x that of Earth/Luna) suggests proof to me that larger ratios are just as likely.

 

[mheslep]

And this is all highly unlikely in other systems? Why? What you call a freak accident, I call all but inevitable given enough time.

Can't be and have life. The event escapes me at the moment, but if the disruption in the outer solar system that caused all that orbital debris dislocation to the inner solar system were a common occurrence then the Earth (and like planets) would still be a bowling pin.

Meanwhile, I'm going with this reference:

Klaatu: There are only a handful of planets in the cosmos that are capable of supporting complex life...

 

[Andre]

Be that as it may, it seems to me that a claim of planet/moon mass ratios similar to Earth's being rare is unfounded.

So as a consequence, would a claim that planet/moon mass ratios similar to Earth's being common is founded? It is not that the hypotheses about the http://www.cosmosmagazine.com/features/print/2421/birth-moon sound very plain and common, do they?

 

[Mech_Engineer]

So as a consequence, would a claim that planet/moon mass ratios similar to Earth's being common is founded?

Looking at just our solar system does not give enough of a statistical sample for proof in either case... but people can hypothesize all they like.

I would hypothesize that it is likely that moons (of all varied sizes) are a relatively common occurence. Given the vast number of stars (and therefore planets and moons) that exist in our galaxy, it seems conceivable that there are many other planets in our galaxy that have similar planet/moon mass ratios to that of earth...

I make no claims as to their (earth-like planets) relative liklihood, or the necessity of a specific planet/moon mass ratio for life to exist.

 

[Pythagorean]

I think Andre's point is that in addition to the considerations of the Drake equation, you also have planet/moon ratio as an additional constraint, and that adding more constraints only reduces the probability.

So a perfect earth/moon combination that's pluto-distance from their sun is going to be a bit cold for life.

I'm not convinced a planet HAS to have a planet/moon mass ratio close to Earth's in order for life to exist in the first place...

 

[Pythagorean]

I'm not convinced a planet HAS to have a planet/moon mass ratio close to Earth's in order for life to exist in the first place...

Well, I guess I'm not convinced that it must be so, but the arguments are reasonable: The moon provides stability in the Earth that allows for stability in the evolution process.

What I meant to say is that those of us born after 1980 do not have a major challenges or objectives of "biblical proportions." From 1776 up to 1991, every generation had a major struggle and a major goal to accomplish: Wars of Independence, American Civil Rights Movement, defeating the Nazis, unifying Germany, discovering vaccine for polio, major scientific advancements, going to the Moon, etc. The characters that lived during these times were larger than life; they did things because they have to be done, no matter the price; they were not afraid to sacrifice anything, even their lives, to accomplish their assigned goals.

In contrast, my generation is wimpy, weak. We cry if we do not have a warm latte, a laptop, and a wireless connection available to waste time away on Facebook, Twitter, and World of Warcraft.

What major challenges do we have? What call have we answered? The latest call we have answered is Call of Duty: Black Ops... we need a major crisis that wakes us up yet I doubt we are capable of overcoming such a crisis.

These is what our forefathers did:
