In the realm of the fantastic, AI (AGI), theoretical propulsion systems (EM drive, Alcubierre warp drive, etc...).
In closer proximity to the here and now, I’m really interested in the emerging study of the microbiome (microbiome... ology? I don’t know, but remember where you saw it first). I believe that we will be blown away when the field comes into maturity and I anticipate that we’ll find that the microbiome effects our physiology and psychology in profound and earth-shattering ways.

Nano crystals and I don't know enough about them to invest properly in any way. It is totally possible that batteries and power supplies as we know them are very soon going to be a thing of the past. They thought Tesla was crazy but once everything went digital I suppose they gave his ideas a closer look.

Plenty of examples of technologies put on the market without their environmental impact being assessed first. Economics before sustainability? Shameful.

The full deciphering of DNA and its mechanisms. This has incredibly huge and wide implications for human life, all life on earth, and potentially terraforming and life being implanted on other planets.

The expansion of the neocortex using nanotechnology.

I don't follow science much, discovering new species, rediscovering species thought extinct, the idea that the speed of light is actually not a constant based on mitigating factors, the breakthroughs with the large Hadron collider, experiments in teleporting photons, and super high speed cameras that can actually show the progress of a beam of light through a bottle of water.

We are living in a Golden Age of space exploration. When I was a kid everything we knew about tbe Solar System pretty much fit in the first few pages of an atlas. Now have visited every planet, landed probes on several of them, and including some moons. Never ceases to amaze, I visit APOD regularly.

Everything? Is that an answer? I do like gravitational waves, they're fun... Higg's Boson was a pretty big leap to further proving the standard model. Still need that link to gravitation though... maybe that's most fascinating, what we haven't learned yet.

Zero point energy and the outgrowth of Nikola Tesla's work on electromagnetics and energy transmission. The developments of many scientists and inventors has been suppressed, confiscated and appropriated since the FBI confiscated Tesla's research upon his death.

We remain addicted to fossil fuels because this technology is suppressed and controlled by quasi-governmental military contractors. This has allowed our corporate kleptocracy to enrich itself by perpetuating our current energy paradigm and assurring that "free energy" remains stillborn.

carbon nanotubes, buckyballs and the discovery of gravitational waves. we live in exciting times, I can't wait to see the new discoveries of tomorrow and what technologies will be born from them.

"String theory" and stem cell research helping to cure previously deadly diseases.

What science needs to do is target whatever it is that's turning my hair white and redirect it towards my teeth but, since they aren't working on that, I'd have to go with CRISPR technology.

World Collective consciousnesses of love, creative, health, awareness, ethical values are the main things that do change by the power of the people.

When humans are harmed by the extreme hierarchy systems like the abuse from Religion or Politics. The world is into the third wave of abuse right now, until the people collectively consciousness change it as the have done throughout the history of mankind.

The developments in cosmology and quantum mechanics are fascinating. But for my money the most directly fascinating is the development of AI. Also very potential scary. Within 20 years AI will exceed human intelligence, it is said. Then it will go exponential. Wow!

Donald Trump...

Memory recall. This has really fascinated me. Apparently, you don't just recall a memory; you recall it into paint shop pro, then redesign it. If you recall a bad memory but you're in a good mood, that memory will be repainted in a more positive version than before. Or vice versa. This is what brainwashing is based on. This also has to do with PTSD; you don't just remember images of what happened, you also store the emotion that went with it. And if that emotion is strong enough, then you "remember" it when it is triggered by a similar stimuli. Research is developing the means of eliminating these emotional memories.

AI..for sure..but string theory is also quite fascinating

I think it is the light and technological revolution so much to blow my mind and now making science fiction difficult to make as it overtakes it.it is an amazingly happy and very scary time. we are as a race is on the cusp of greatness yet hanging over the obis where we lose everything. our surroundings are getting so state of the art but are crumbling too. we have so much intelligence at our fingertips and yet we grow stupid because of it.skynet is here astalervista baby.

Em drive/antigravity magnetismic vehicular adaptations.
Magnetic field driven lighting.

Glowing trees to replace street lamps.

Cancer research. More survivors like me hopefully.

The fact that they are about to cross the [ quantum supremacy] limit in computing .The study of sub atomic particles fascinates me

Watched a program where diseases such as small pox, Plague and alike are being used to fight Cancer......it seems we are definately on the path to eventually ridding humanity from this dreaful disease.

CRISPR. Gattaca is about to turn into a documentary.

The research into soil microbes and fungus as an alternative to chemicals and fertilizer and the offshoot organic cancer drugs it has produced is amazing; most of this work is being done in Cuba and is the direct result of the US embargo. Seems necessity is the father of invention.
