Science is taking huge leaps right now, in fact a group of scientists actually managed to make object mostly invisible (reflects near 100% of the light), granted, it was super complicated and they could do it only to certain sized and shaped object.

But that i a good example how science can one day figure out things you'd not have even dreamed of some time ago.

Wait, but, if it reflected almost 100% of light, wouldn't it just be black?

no it blends to the background.

Black if it absorbed all light.

Right, and white if it reflected all.

That article makes no sense.

You can always compute faster, simply by having more. If one core can process (note: small numbers for simplicity's sake) 100 calculations per second, then two cores can process 200 calculations per second (in a perfect world, of course).

I don't see how there can be a limit.

I don't think he meant reflect, he meant refract. The light is bent around the object so as to appear to make the object invisible.

I love the way you guys know better than physicists who have probably spent years studying this equation. here is a link to the whole paper if you wish to make sense of it (4 pages 0f mostly equations)

Ppl used to think earth is flat, were they right?

I am saying you can't predict what kinda innovations there will be. The next big thing could very well shake the whole basis of our understanding of universe. Theories get proven wrong, fixed to be more accurate as the science advances.

edit: and about reflect / refract, there are multiple theories of possible ways to achieve partial invisibility.

One way is to create mirror-like surface (reflect light in certain way) or refract (bend light that hits the object so it looks transparent). I think there are scientists working on both atm.

If nothing else this equation will provoke more study into this area by physicists. Also can you tell me the meaning of the equation or is this just arm chair physics on all our parts?

Advanced quantum physics. I would say thats well over my head. I will probably never see that complex equations in my life.

I know they didn't, that's the point. I want to know what it is and how they arrived at that answer. It seems to be bounded by more than the speed of light.

There is a practical difference between speed of calculations and number of calculations that can be performed simultaneously. In most instances the next calculation is dependent on the one before it, so adding infinitely many processors isn't really the same thing as one incredibly fast processor.

Covered some of that back in college, but with no utilization for over 20 years, I'm brain dead as far as calculations are concerned.

Fuzzy Logic would benefit from an infinitisimal amount of processors.

From the article, I believe that they are looking at the smallest amount of time that it would take to change with relative certainty a single qubit to a different value. The difference between what they did and what was done before is that while other people assumed that the bit had to be changed completely, they looked at the time it would take for the energy state to approach the new value with the bounds remaining "tight". Then they proved that this pretty damn close approximation is valid with a bunch of quantum physics I'm not going to pretend to understand.

In any case the article didn't do the paper justice. It is worth it to read the first 3/4 of the first page, not really any math involved.

If quantum physics can go only that far, there is nothing stopping a completely new technology from being invented in next 75 years.

There are a ton of scientists, physicists, and mathematicians who are so set in their ways, that they refuse to acknowledge new trains of thought. Take string theory for example.

I hope you mean that string theorists that have now been making more and more complex yet practically useless theories for 20 years when you say scientists who are set in their ways.

No one's arguing their research, only suggesting that our current understanding of physics is not perfect. Which it isn't.

TBH the only people in this thread who have really pretended to even know what they are talking about, or what the scientists are talking about are those who are defending the article.

Those of us who disagree are not saying we know the answer... just that what we know, and what is "possible" typically goes through dramatic shifts in the span of 75 years.

I think there will be a different way to process information in the future. I mean, sure, 75 years ago we had near nothing in terms of computing technology (on a scale relative to today). However, another part of me says that 75 years is too long, and it could actually be shorter by the time we actually reach that capacity.

But what would I know, Im 17, lol.

Yet you have enough common sense to recognize that 75 years is a very long time in terms of science or, more so, technology. Just don't say lol so much.
