Yes, it is true to say that there are many undiscovered scientific wonders in the world. This is evidenced by the discovery of the massive lake found under volcano in Bolivia. We all know the benefits of the natural resources and how it earns our country income. They promote tourist attraction.
Between vast underground cave systems, huge oceanic canyons and the recent discovery of the lake, I think there are still undiscovered wonders on Earth. Who knows what scientists will find under the ice, in rock or oceans. There may be discoveries at the bottom of our deepest lakes, and in forest areas. Scientists haven't seen all there is to see here yet.
I feel that in terms of discovery and new frontiers there are plenty of wonders to be found within the natural world. Although the larger wonders such as the Grand Canyon are unlikely to be found lying around in the middle of a rainforest, there are still unexplored depths of the ocean to be investigated.
The mystery of Easter Island and the Moai statues that inhabit it is something that most of us are at least vaguely familiar with, but the fact that there are still so many legitimate unanswered questions surrounding the island is in itself quite remarkable. Theories have been proposed that involve ropes, sleds, rollers, levelled tracks, or even that the people slowly rocked the statues back and forth to their destination. Attempts have been made to recreate the methods that could have been used, but most resulted in damage to the statues, or would have required hundreds of people making just 0.08 kilometres of progress per day.
The truth is, we don’t really know exactly how they did it. But however the Rapa Nui managed to move the Moai, they would have certainly needed to be incredibly patient, creative, and organised to make them a reality.
