What do you think is the highest technology possible given the physics of the universe?

Just 100 years ago things that seemed impossible are now a part of our daily lives. Airplanes, cell phones, the internet etc. I can't even imagine what kind of technology will be possible in another 100 years. What if humans didn't blow the planet up and were here to develop technology for millions or billions of years? What do you think is possible?What do you think is the highest technology possible given the physics of the universe?
100 years ago - Einstein calculated gravity bends starlight. General Relativity was becoming accepted. The 2 Laws of Thermodynamics had been in place for 50 years (while the 3rd law hadn't been clearly expressed).

We still don't have faster than light travel or perpetual motion.

I am not sure why you believe we will be around for too much longer. In this century we will have created artificial intelligence much more capable than ourselves. We will understand ourselves to such a great extent that crime and mental illness will be rare - almost unheard of. Synthetic Nanotechnology will have demonstrated its usefulness in few and quite contrived situations while microbiotechnology will be pervasive. We may be plugged in directly, making school a thing of the past. We will have seeded Mars and the seas of Titan with life (if its not already there), We will have extended the human life span so that we do not die, rather fade into the electronic media after a century or so, losing our hormonal drives slowly during the transition.

This is the technical future. With non-locality a reality, we *might* discover Magic. If so, all bets are off.
Arthur C. Clarke's three laws of prediction:



1.When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.



2.The only way of discovering the limits of the possible is to venture a little way past them into the impossible.



3.Any sufficiently advanced technology is indistinguishable from magic.





If we continue to evolve and don't die out, we won't even be human in a billion years. We can't even begin to imagine what such a race can be capable of. We don't even yet know all the physics there is to know.What do you think is the highest technology possible given the physics of the universe?
The odd thing about this question is that there is simply no way of knowing if there is a limit or not. Only one author I know of wrote a science fiction novel that included carrying around notepads and phones that match those we have today. One SF author invented the water bed and never bothered to patent it because is just seemed like no one would ever be interested in actually making one. What new discoveries will be made that make everything we do these days totally obsolete? We won't know till it happens. Every time someone decides we know all there is to know, someone else decides that person is an idiot and invents something new.
It is truly impossible to say. Imagine explaining airplanes, the internet, and heart transplants to Da Vinci. He may be able to understand certain things quickly (helicopters, possibly internal combustion engines, etc) but I doubt even a genius could comprehend the internet properly if he had never seen anything like it before.What do you think is the highest technology possible given the physics of the universe?
Being able to make a planet or a star, or just a Dyson sphere around a star.



In 1966, a blood sugar meter was science fiction. I've been using one more than once a day since the middle of August, 1983, except for when I was in an induced coma for six weeks. I've seen four science fiction things become science fact within my life-time so far. However, being able to make a star within 500 years??? Well, maybe even that may not be as impossible as it may seem right now.
All technologies will have to improve, nano tech for building, food tech for fast growing population, clothing, heating, storage of food, and maybe space travel without fuel burning rockets.

We have many emerging super technologies now.
