90% (we've only scratched the surface)
75% (there still so much more, we got a long ways to go)
50% (we've seen a lot, but there still equally more to see)
25% (there's probably still something big out there)
10% (Most of what's out there, we know now)
Less then 10% cause satellite maps of everything, even the sea floor
Seems like a better analogy would be going to St. Helena and saying you have seen the whole ocean. As far as areas on land that are unexplored, large chunks of places like the Amazon rain forest and New Gueinea are unexplored, in fact there was a research team who went to a northern part of Australia recently and found a new large gecko species.
might be unbelievable stuff at the bottom of the ocean, unbelievable diversity to go with it, at deep deep depths ? probably not.
I think people need to understand that the sea floor is not 'imaged' by satellites. There are images created based off data, sonic, geologic, etc.. But they dont take pictures like they do of land masses. The images you see on google maps or whatever, are not photographs, but rather mapping recreations.
There are some places where the bottom can be seen, but usually just off shore.
Most of the ocean hasn't been explored at all, and we're finding new, weird stuff every day. Including deeper trenches, and stranger life.

One thing that we haven't even touched the surface on is buried cities. So no, we have millions upon millions of years worth of our origin left to discover.

Think about this stuff, that carving in stone. That was done by someone 12,000 years ago. We have no clue who these people were, what they did, why they all died, etc. It's really interesting stuff.

inb4 we send robots to explore the deep oceans and they find Atlantis, which is full of aliens of course. The aliens show hospitality to them but notice that robots cannot express feelings. They see that they are programmed to be a tool we use, so the only right thing to do is to reprogram the robots and give them true intelligence. Then the robots returns to the surface and annihilates the human race, the end.
There's lots of things not yet explored under your feet. D:
depends on your definition of 'discovered'
and your definition of 'the world'
the world itself, excluding Life, we've close to completely discovered, imaging radars for caves/deep sea floors, terrain mapping etc.
but as soon as you throw life into it, it's a whole new story, and we have a lot left, i'm still waiting on some silicon based lava worms, haven't been discovered since they don't like the low pressure area's where lava's venting out etc... lol (joking mostly)
Still I cry, tears like pouring rain, Innocent is my lurid pain.
Given satellite technology... if we're just talking about places then much of the geography of the oceans. Land, not so much.How much of the world do you think is still left undiscovered?
If we're talking creatures and critters of all kinds, probably quite a few.
The ocean covers 71 percent of the Earth's surface and contains 97 percent of the planet's water, yet more than 95 percent of the underwater world remains unexplored. Snipped from NOAA
I think we have much to discover/learn yet. Real interesting stuff to be found, I just think we lack the technology to discover it, or the money to develop technology to discover it. Then again, i'm just one random dude talking out of my ass.
There's an exact scientific answer to this question, and thus asking people their opinions on the matter is sort of moot. Although, I suppose it does give us a nice picture of how badly misinformed people are.
90%+ because we quite literally have only scratched the surface. Even excluding the oceans because everyone talks about that, the deepest hole ever dug was really not that deep in comparison to the thickness of the crust and then there are layers even below that, and in digging that hole we discovered the temperature changed a lot faster than we initially thought so there is much that just digging into the crust further could tell us.
And then obviously we have the oceans most of which remains unexplored, and then the rain forests and deserts and basically any terrain that civilization doesn't exist in, I mean even the Australian Outback still had an aboriginal tribe living in it that had never seen civilization until I think it was the 80s, and there could still be more we don't know about.
The oceans... The Mantle... Our own crust. Much is largely unexplored and unknown.
We haven't even found the Mole People yet.
Seriously, in regards to the surface on the planet not covered in water, we have a pretty good understanding of. In regards to the anything under the oceans and the vast majority of everything under just the very top of the crust is unexplored.
As far as habitable land goes, we've discovered like 99% of it. As for the rest... Who gives a shit?
I don't think this matters nearly as much as you think it does.
Even if you just think about the depths of the ocean, we still have a lot to discover.
