Okay, next set:
Weather control will absolutely become possible in the future. Although I cannot imagine it being good for the planets ecosystem, I doubt that will stop us. It should, in my opinion, be mainly used for the controlling of harmful, dangerous weather; tornadoes and hurricanes in particular. It would save many homes and lives, and stop disruption of the natural habitat that it would normally destroy. It may also be used in a more harmful way, and eventually become a weapon; with the ability to heavily damage enemy territory.
With human life as busy as it is, food pills may become a more viable and popular option rather than actual food. It would be simple and efficient, and contain all the necessary nutrients. Will it completely take over “real” food? I doubt it. In fact, we will probably need the actual food to produce the pills. But, what it will become is an alternative for those with busy work lives. Pills would be small and easy to fit in ones pocket, and not take up unnecessary time to eat.
TV in its current form will be eventually overtaken by other formats for primary entertainment. I believe there is a large possibility that its replacement will be a full sensory experience; being surrounded in full virtual 3 dimensional space, with the invention projecting an image in such a way that it would be as if one is actually there. Videogaming, a fairly new development in entertainment, will eventually become predominate that all humans will enjoy. It is in early stages right now, but it will advance onward, until virtual reality devices - similar to that for the future TV units - will be what people are playing.
Transport systems for space travel will use warp drives. With this, warping space using equipment will obviously be rendered possible for a manner of different reasons. A personal musing for this is that wouldn’t a warp drive or similar device effectively gain a gravity field in front of it when operational? If we follow this diagram:
At the front of the device, with which space will be “squashed”, surely a noticeable gravity field will be produced? If the warp drives power is going to be great enough to bend space such that it takes less than the speed of light to get to a nearby star, the field would be quite tremendous. If this is true, then it could cause some potentially dangerous problems.
A way to effectively “preserve” information from matter into a kind of cryogenic state, so that it may be used at a later date, may be found. As physical objects are simply projections to which information is present, a way to store the “data” may be figured out. This would be by far one of the greatest revolutions in human scientific progress.
Teleportation will become a reality. The concept is simple, but our technology is not up to it at the present time. Preserving information states, as stated in the above paragraph, could be the answer. Scientists have already managed to teleport a single atom, so it’s definitely possible, and although we seem to be a long way off from the atoms of an entire human being, it is definite future possibility.
Invisibility – something which seems mostly fantasy right now – is something that is a definite possibility. A way for such a thing to be made is find a way to effectively warp light around the, say, clothing, thus light from around the object instead being absorbed by the eyes.
Will time travel be possible? To the future: definitely. The ability to bend space (thus causing a gravitational field) using technology could be a viable way to do this, rather than going all the way to the nearest black hole. This seems like a simple enough way of travelling in time. But it’s to the past that people wonder about more often (if we ever do, why can’t we see them around us, why has no-one stopped Hitler? etc). My speculation to this point hasn’t yet resolved unfortunately. I suppose the answer is similar whether time is linear, cause and effect, or has a more holistic framework. I have created two illustrations to visually represent these two versions (because they’re always fun!):
With time set in a linear fashion, the constant stream of states continues through time in a set direction, with the inability to ever revert back to previous states, thus a “locked” timeline.
Time could also be a holistic entity, with events happening in sequence, but each state metaphorically set apart individually across a 3D sphere. This way, by means I haven’t bothered to think about much yet (possibly having to transverse to different dimensions), past events could be revisited. Holistic in reality, but the universe maintaining a natural progression of entropy (which is why you don’t see people walking backwards or cups rebuilding their pieces back together after being smashed onto the floor).
I’m quite certain the most believed theory is that of a linear space-time, but it must be said that a holistic one would be a lot more fun.
Sorry about getting carried away with time travel. The whole concept is just so intriguing to me...
