PhysOrg said:
We experimentally demonstrate a class of tractor beams created by coherently superposing coaxial Bessel beams. These optical conveyors have periodic intensity variations along their axes that act as highly effective optical traps for micrometer-scale objects. Trapped objects can be moved selectively upstream or downstream along the conveyor by appropriately changing the Bessel beams' relative phase. The same methods used to project a single optical conveyor can project arrays of independent optical conveyors, allowing bidirectional transport in three dimensions.

F'YEAH
 
True, but still...30 years ago who would have thought our iPhones would exist and do what they do? Science almost always progresses because someone says "What if...?"

(sorry for a slight threadjack Matt!)

:party
 
Science Fiction becoming real, what do you want to bet the scientists that are building this stuff are Trekies :laughing So cool :nerd

30 years ago I knew that Android would be better :x

30 years ago the science was already in place for iphones, the tech had not reached that level.

The science for faster than light travel is non existent.

Everything has an explanation, and nothing is impossible.
Human ingenuity is virtually limitless, provided we don't kill ourselves off or the sun doesn't explode ahead of schedule :laughing

I was having a discussion with a friend and we were talking about ideas that would require better battery sources. I think..I think we were talking about solar panels or something, and he said that the problem isn't generating the power, it's storing it.

So we started talking about batteries, and I suggested that it's possible that we may find a way to produce batteries that are not only smaller/lighter, but can also store more energy/transfer the energy more efficiently. He said the technology doesn't exist, so it can't happen. I then shared with him that I had trained with a professor who was working in bioengineering to explore ways to store energy organically.

He then just flat out said "If it could have been done, it would have been done already." I was flabbergasted. A friend started talking about something else, so we moved on, but..come on!

I think it's clear that if it were that easy, everything possible would have been invented already. However, that's clearly not the case, as I am constantly surprised by what we humans are able to invent, and I can't wait for the goodies the future will bring with it.

Wow. I haven't heard that one in a while.

And yeah...battery technology, or more generally energy storage, is currently the gating item holding back so may cool advancements.

If only I were smart or something. :toothless

the limits of human creation are limitless imho

I made the comment that we are living in our parent's "future" on fb earlier and only my pops really got what I was saying :laughing I'm not Ernie old but I'm no longer a spry chicken! far from!

todays technology is things my parents saw as hypothetical dreams on tv. Star Trek being this instance. It amazes me that not only did someone think this possibility up 56 years ago but it also took us 56 years to come up with a functioning product.

We live an an amazing world - I remember growing up using my first computer (commodore 64, playing Radar Rat Race) and now I have more power in a calculator.

I continue to hope that the things I see on tv are realized in my lifetime!
 
The differ me between an iPhone and space travel is so utterly vast it's kinda funny to even have them in the same sentence. Am iPhone is a toy, and fun little plaything. not to mention those little playthings make a lot of money. That's why they exist.andthats why flying cars don't.

I actually don't se Dont this world as all that amazing. All this tech, all this glorified mindless entertainment doesn't actually advance us or make us much happier. Bit it does eat up finite resources at an astonishing rate. All for toys. It ain't the future, for 2/3 of the planet is pretty much the same except there's a lot more guns. We live in a bubble utopia of humanity. And it isn't going to last.

Faster than light travel,or even somewhere close to half that speed,is something humans may never do. I hope I'm wrong but what is required is so crazy, the amount of effort put into it....Just getting a handful of protons up to near the speed of light requires the most complex machine ever built by humans.


And even then, space travel would still be a monumental effort.thedistances are so imesme it isn't even really conceivable by humans. I'm a huge sci if nerd and insider cosmology and understanding of the functions of the universe to be among the greatest human achievements there are, I dont see humans ever getting off this rock in any kind of meaningfull and large scale way.

Short version: People are working to see "what if?". Keep in mind, that iPhone may be a toy but it came from somewhere. That touch screen interface, the computer chip inside, the amount of memory it has, everything. Oh, and flying cars DO exist, they're just not practical (or cheap) enough to be as prolific as iPhones.

For an artist, you have a disturbing lack of imagination.

What you see as a "toy" is a serious tool to some. And even if the iPhone (or any smartphone) is a toy, the technology that goes into making it is most certainly not.

The Slinky is a toy, but the technology behind it was for the precise reading of steam pressures which is most certainly not a toy.

You are becoming more and more pessimistic Kevin, I think you need a vacation.:laughing

Sadly that's not true.

This.

Anyone who believes in space travel needs to sit down with a computer and work out how many miles there are in a light minute. (The distance light travels in sixty seconds.) The universe is around 14 billion light years across.

The current tech ( and the laws of science) make serious space travel almost impossible. Within out tiny solar system is extremely difficult and horribly expensive. And slow. It's insanely expensive to lift ONE ton of stuff into orbit.

Just because you can imagine something does not make it possible. A 300 pound linebacker can imagine running a marathon in 2 hours, and I can imagine bench pressing 400 pounds.

It was my vacation that made me pessimistic :laughing


But in regards to space travel, our species is actually regressing, not advancing we are way behind where our highest point had brought us. I'm a huge astronomy nerd(it's what I wanted to be other than an artist for most my life). We are so far behind even e 70's it's stupid. Right now, if we decid to go back to the moon, some we HAVE DONE, most people in the industry estimate ten years from start point. TEN YEARS, and that's using all the plans that we have already designed! The tools don't exist to do any kind of actual manned space flight beyond the exosphere.


We are worse off now, and it's continuing to regress year by year.

And like i said, just getting a bundle of protons to around 7/8 the speed of light requires particle accelerators that are literally the most complex machines humans have ever built. I'm not saying it isn't possible, but it's not probable. I think th elimination sof human nature will never allow us to work together enough to full achieve these things. And with our population exponentially growing, the vast resources required are going to continue to be eaten, and just feeding and housing the world will be of more concern.


It's not that I can't imagine it, I think a focus on space and scientific exploration should be one of our focuses. I grew up watching star trek, and fucking love TNG, ewvery astronomer loves this shot and dreams of it. so does every astrophysict. i WANT near light travel, it would be th emost awesome thing ever. but the physical realites of even 1/2 the speed of light, are so astronomical, and even then its still too slow. hell, the speed of light is to slow...
