What type of physics do you find most interesting today and in the future?

I have always loved Astrophysics, but the future is in Particle Physics. They are now developing atom sized gears…

Quantum physics, because it deals in probability and raises the question (at least for me) of objective reality vs subjective reality.

Meta-Physics, and Experimental Physics, Because I love to wonder what if.

I’m with @Yetanotheruser. Quantum physics posits the possiblity of im travel, right?

All of it.

I don’t know where nanotechnology fits into the scheme of those listed, because it’s not “particle physics”, although it deals with physics at the particle level. That has the promise of whole new classes of materials and machines.

Quantum and particle physics could help to discover new elements, or fascinating new uses for those that are already known.

Geophysics could help us to tap the heat coming from the center of the planet as an energy source for providing heat where it’s needed on the surface, including for electric power generation.

I’d like to see the concept of exotic matter, particles which would have a negative mass, come to light. I feel that most of our power generating problems would cease to exist if we discovered how to utilize negative mass particles. There is not much evidence that negative mass matter exists, but theoretically according to physics they could exist. This discovery would be important since the different properties of positive and negative mass particles colliding with each other would produce a unique energy gain without violating any laws of physics.

There is a fringe element in physics which speculates that what is known as dark energy/matter is really subquantum particles made up of positive and negative mass. It has been speculated that the energy gain created from these subquantum particles is what is causing the universe to expand faster rather than slowing down from the initial quantum fluctuation starting the ‘big bang’. There are some respected names in science within this group. Current relativity theories oppose the concept of a background medium existing.

I think I would find quantum physics most interesting, but I dare not measure to find out, as I do not want to collapse my waveform and get stuck in any single state.

Biophysics. I think that biology in general is going to be producing incredible results. It has recently been found that photosynthesis depends on quantum mechahics That gives a good argument agains those who claim that quantum events are too small to affect the chemistry involved in consciousness. That does not mean it is necessarily so, but it opens up some interesting possibilities.

All of the above. The search for the nature of dark matter and dark energy is particularly interesting.

I’m fascinated by all of it, even though my brain can’t process the maths necessary to fully understand it. I settle for layman’s explanations, and “ooh” and “aah” at the implications. Science is cool.

Cosmology and astrophysics are the most interesting. The physics of black holes will someday lead to a unification of quantum theory with relativity.

The Human Brain Project is an attempt to simulate the human mind in a super computer. It is very ambitious but has European Commission funding. It should give us new insights into how the brain works as well as teaching us how to build better computers.

@flutherother maybe it will lead us to the singularity
