The future is coming, yes.
Not quite there yet, though. We still have to get over the part where everyone and their aunt want to buy a flying car because it's hip n' cool and then proceed to soar up into the sky and immediately come down in flames like Icarus.

Dammit I'm not supposed to be posting, but that is officially now at the top of my lottery wishlist.

Though deep down I hope to god it doesn't take off (edit: excuse the pun, completely accidental :smallredface:). Where I work is 5 stories high, and I could really do without some learner driver crashing into the top floor. Bollards will have to be 50ft tall :smalltongue:

We can never have flying cars. People are idiots. If one can't stop at a STOP sign, how can you expect him to fly anything?

If flying cars ever become commonplace, I'm moving to the countryside (and possibly installing SAM to be safe from drunken imbeciles).

You have made my day.

But seriously, we have, today, a lot of those pretty pretty stuff that sci fi writers told us about years ago, but most people wont realize because either:

A) They dont like Sci Fi
B) Our gadgets are smaller and less flashier than those portrayed in sci fi movies
C) Our gadgets ar not nanotech
D) Our gadgets slowly grew into what they are today so no one realized we actually have them

More evidence that the future is already here: Our gadgets have Touch Screens! How cool is that!?:smalltongue::smallbiggrin:

This is pretty much the main reason you don't have flying cars or jetpacks. That, and when it does crash, you're probably going to sue whoever made the vehicle for making it unsafe.

Why "you?" Because the main reason I don't have a flying car is that I don't have the cash and equipment to spend on refitting a car myself. :smalltongue:

So... Never?

It's true that fewer people died from lack of clean water in 09 as did in 08, but there's still about a billion people living without clean water. As we add more and more billions of people to our planet (hopefully we will stabilize around 11 billion), it gets harder and harder.

As for death from disease, that really is never going to be eliminated. There will always be sicknesses, and of course even if we eradicate things like AIDS, something else will probably arrive in its place (just like AIDS showed up originally).

That's what I meant. Obviously diseases will never be completely defeated, as genetic mutations of viruses and bacteria will ensure that a remedy against a particular strain of a certain disease will stop working against another strain; but the fact that people still die from diseases for which the cure is readily available and cheap is a paradox of our era.


QFT. To further elaborate, I wonder what sources of energy we will use for all our increasing technological trinkets.

There's an interesting theory about energetic progress, made up by a soviet scientist whose name was Nikolai Kardashev: this guy made up a scale to measure the progress of a civilization based on the mastery of energetic sources. The complete Wikipedia article (http://en.wikipedia.org/wiki/Kardashev_scale) is interesting but long: for a brief summary suffices to say that Kardashev designated three cathegories in which a civilization could fall:


Type I: has achieved complete control of the energy sources of its home planet;
Type II: completely controls the energy resources of a star system;
Type III: masters the sources of an entire galaxy.

Science Fiction expanded this classification to Type IV, in which all the resources of the Universe are exploited, and Type V, in which are considered multiple Universes.
Suffices to say that nowadays Mankind is classified as Type 0.72: we should reach Type I in 2100.

More on whether we live in "the future" or not:

Tech
- This road-legal flying beach buggy (http://www.parajetautomotive.com/) went from London to Timbuktu.
- Mobile phones and t'internet have been mentioned
- Prostheses seem to get better every year, as do device-brain interfaces, so bionics and cyborgs may be just around the corner.

Bioscience
- Genomes are now our playthings, which is fun.
- There's oodles of new work being done in better understanding and finding better diagnostics, treatment, prevention, etc. for practically every disease under the sun. Except where it really isn't necessary, because said disease has been either pushed well to the fringes or likely to be completely eradicated soon, as is the case with dracunculiasis (the "disease of little dragons") aka guinea worm (http://www.who.int/dracunculiasis/en/).

Space!
- There are currently 6 men living on board the international space station.
- Asteroid mining may be on the way, with experiments in automated drones landing on, taking samples from, and leaving asteroids
- No warp drives yet, however.

Kaiyanwang

There is a lot of things to discover yet. Proteins non only are encoded in genes, but are finely tuned and regulated.

Gene transcription and translation is regulated, as well protein lifetime.
Moreover, there are parts of the genome that were considered "junk" before, and now are supposed part of regulation or something else.

Of course, we are making steps and steps forward, but we are not in the "plaything" phase, yet, IMO.

Fair point. Perhaps rather than playthings, we should say "an increasingly open book". I do rather like how much the science of genomics has expanded from practically nothing over the past 20 years, however.

I was so about to say, word for word, that we've had flying cars for a generation and a half already. But you beat me to it.*

By a few hours.


By the way, what separates these things from being just a plane you can drive on the street when you're not strafing the houses next to yours because they have a nicer paint job?



*(Someone actually did create, and attempt to mass produce, flying cars around that time, though. I'm too lazy to look up the year and any names, but lack of funding meant that the fully-functional flying cars (which were basically these things but red) couldn't go into mass production.)

Cicciograna

Is this somewhat related to a cone? A cone perpendicular to two axes labeled with a "s"? :smallconfused:

In Relativity s2 indicates the invariant interval or separation between two events: from a geometrical point of view it is the distance between two points on a Minkowski diagram; this is a quadridimensional diagram whose axes are (ct, x, y, z): the separation between two points on this diagram is, as stated


s122 = c2(t2-t1)2-(x2-x1)2-(y2-y1)2-(z2-z1)2

For events characterized by s122 > 0, a reference system can be found in which the two events happen at the same position: a finite time passes between them and a relation of causality between the two events can be found; the interval between them is said timelike. On Minkowski diagram s2 = 0 denotes the separation between two events linked by the speed of light: therefore it describes the surface of an hypercone, called light hypercone, which delimits three zones on Minkowski diagram. Considering, for the sake of simplicity, just one spatial dimension, the hypercone reduces to a regular cone:


http://www.engr.mun.ca/~ggeorge/astron/shad/lightcone2.gif

As you can see, regions in which s2 > 0 are called "past" and "future", depending on the value of t, so this is why the Future is when s2 > 0, given that, for us, the Past is...well..past :smallsmile:

Hope my explanation was clear enough. It's 1 AM and I'm a bit tired...

Actually, you can die from lack of disease. There are certain bacterias that we need in certain places of our bodies to help us with certain things... And there are certain procedures for fixing the problem when there's not enough of them.

Spoilered for gross:
There is a procedure that involves transplanting poop from one individual to another (usually a relative) to fix a situation where one's bowels lack certain bacteria that help keep things smooth.

No, you're right. But since past is already past, and there's no reference system in which it can be future again, for the sake of the current discussion (the one about the Future) I chose to omit the condition on t > 0.

Wait... people took that seriously? I was just trying to see how many Futurama references I could cram into one thread...

You are welcome.

Silly people... We can't know what's in the Future until we know what's in the Present. *Opens the Present* Turns out, it's socks. *Holds up the socks that were in the Present*

well **** the future. seriously, who gives socks?

What would you have the future do then? Add antimatter? Add negative matter?
Antimatter is thought to have the same properties of mass as the matter we know and love so well.
Some types of hypothetical exotic matter might on the other hand.

OBJECTION! You cannot change the mass of an object, well without breaking a piece of it off, besides the point.

You only said "changing the mass" - you didn't give any stipulations. Besides, according to Special Relativity it is trivial to increase the mass of an object.

As for negative matter its mass is, well, negative.

Well duh, but in and of itself it would suck, as a torch ship outputting just photons from the annihilation has ridiculously low efficiencies. Using the annihilation to heat a medium, like say liquid hydrogen would be much more efficient. It would still count as 'breaking a piece off' though.
