Have human kind nowadays the abillity to enter in the center of the earth, in the lava section?

No we don't have the ability now, not only is the temperature too great, there is way too much pressure for us to overcome. It would crush anything significant before we got to far. \n\nThe farthest down that we have been is only a few thousand km, and that with a tiny drill.\n\nThe deepest holes in the crust are natural. Volcanoes bring up material from tens of km depth. The crust thickness averages about 18 miles (30 kilometers) under the continents, but is only about 3 miles (5 kilometers) under the oceans. It is light and brittle and can break. \n\nHere is a great article that explains a lot:\nhttp://www.livescience.com/technology/050407_earth_drill.html\n\nThe reason we explore space more, is because not only is it easier to accomplish, but it is also far safer and less costly. I agree though that exploring below the Earth can be quite rewarding, but we simply can't do it as of now.

You know that's a good question but I don't think so. With all the modern methods of travel and exploration, I don't' think there is...\n\nHave a great day..

I figure the only places left are some of the more inaccesable dense rainforests of the South American continent. But the other possibility would be underground, cavers or speliologists have been trying to probe the depths of the earth by exploring underground caves and tunnels as well as flooded waterwaters to see how far they can go below the earth. That besides the oceans must be the last place where humans have never ever set foot on in this earth.

the core of the planet is said to be liquid under pressure, hence volcanoes.  the earth isn't hit with enough meteors etc to much influence the mass of the planet, but as the sea-floor dictates, can change in size.  an example is the two of the main plates, I believe in the area of the pacific rim.  these two plates are moving apart, at times exposing the hot core which pushes its mass into the cracks and cementing the 'spread' of the two plates. \nif the other plates of the planet move likewise, then yes, the world could increase in volume, and give rise to a bigger earth, in lieu of magma escaping from our depths, or by areas of the earth becoming less in depth to the core, like an icecube in a glass of water. \nsci fi of years gone by have mentioned the core in relation to volcanoes.  the implication was that the volcano activity was putting extreme pressure on our core, which if not filled by natural forces, would create a partly filled container under pressure.  the natural result was thought at the time was that the earth would explode or implode.

The Earth has been hit thousands of times.

Depends on how you define "middle." The center of the earth is the core, which is just short of 4000 miles down from the equator. If you're talking about the definition of "middle" in terms of the surface, then the only natural center is the Equator, which divides the southern and northern hemispheres. Since the Earth's rotation is uniform (at least in terms of unaided human scale observations), any attempt to define longitudinal hemispheres winds up being wholely artificial. The prime meridian (0 degrees longitude) is simply defined as the line that runs between the north and south poles that passes through the center of a particular telescope located at the Royal Observatory in Greenwich, England. There are historical reasons why that line was chosen, but at the end of the day, it's as good as any other one that you might choose. It's just that nowadays, it's what everyone agrees upon. So the middle of the western hemisphere is at 90 degrees west, 0 degrees latitude, which is very near the Galapagos Islands in the Pacific ocean and the middle of the Eastern hemisphere is in the middle of the Indian ocean, southeast of Sri Lanka.\n\nThe middles of the northern and southern hemispheres are the respective poles.

Thed center of the world is the very hot core of the earth. Not a country or a city.

The deepest "hole" drilled into the Earths Crust was 4,644 feet deep. Scientist were trying to reach the Moho, a boundary formally known as the Mohorovicic discontinuity. It marks the division between Earth's brittle outer crust and the hotter, softer mantle

There are many different things inside the earth.\n\nThe heat caused by the extreme pressure makes it semi liquid.  The heavier metals tend to work there way to the center.  While the lighter elements stay closer to the surface. \n\n In short, there is molten rock and metal inside the earth.

earth of course......\nthere is a layer in our blue planet called the mantle which lies between the outer crust and the core.. its the biggest layer even...

the earth has been around for 4.5 billion years and humans have been around for just a few hundred thousand years and we have only been industrial for 200 years and in the time before that the earth has seen comets,tectonic plate movements, solar flares, a reoccurring ice age, the devastation of an entire dominate species, volcanoes, earth quakes, great floods, and sky blackening fires\n\nthe earth has been thru alot and we as humans are no difference. our planet has seen em come and seen em go and will more than likely out live us.\n\nso the tsunami is a natural part of mother nature and not due to us drilling for oil

Pluto..a cinch. Just go to Disneyland and wander around you are bound to find Pluto.  You an even hug him if you like!\n\nThe center of the Earth well that's hundreds, if not thousands of years in the future.  The heat and the pressure of molten iron (although at the exact center of the earth one would be in an anti gravity environment..like in outer space, because the mass of the earth is pulling on you exactly the same from all points around you).  The heat and pressure are unimaginable and it will take man many many generations to solve this problem.  We might just send a probe there..why risk a human being. Androids will like molten iron...they can relate to it..right!

it's always been like that.  It's just that as the world becomes more and more populated..we are informed of the earthquakes/eruptions because of their risk of harm to the people who live around them.  But there is no increase.

The surface of the Earth turns to molten lava.

Prooving that the earth is not the center of the universe and that it rotates around the sun. Thoe simple as it seems today, this fact sparked the fire for future generations of wonderers to explore and ask question that were forebidin a few centuries ago.

These features you're noting, like rivers and oceans, are on the Earth's surface on a layer called the crust.  Lava is molten rock that exists UNDER the crust in a second layer known as the mantel.  The water doesn't 'cool down' the lava because it is seperated by a thick layer of rock.

It erupts from he center point of the ridge from underneath the crust of the Earth. The center is the oldest point, seeing as how the material flows away from the peak of the ridge. It's like Earth's pressure valve, Hawaii was formed a bit like this.
