According to Hollow Earth theories, there are holes in Earth's North and South poles. Some search engines shows more photos about the holes than others which are censoring them and have done it for years. If you follow the search engines activity it clearly shows.

Few years ago NASA astronaut Scott Kelly was in year in space mission where he sent to his fb profile all kinds of space stuff, for example how city lights look like from space. There was too possible to ask questions from him. I sent message to space to Scott and asked that can he take a photo of assumed holes in north and south poles, but he didn't answer anything.

There’s Life Inside Earth’s Crust

Revelations about microbes living deep inside Earth’s crust are challenging scientists’ conceptions of life and how it evolves.

The way to spot a cold methane seep on the ocean floor is to look for the life that gathers around it, like antelopes at a savanna watering hole: clams, mussels, crabs, shrimp, fish, sea anemones and creepy, otherworldly worms. These seeps, exposed by movements of tectonic plates or other geological processes, allow ancient, deeply buried methane to burble through the Earth’s crust and into the water column, where it becomes a kind of manna from heaven — a highly energetic food in what is otherwise a barren desert. Single-celled microbes eat the gas; the crustaceans, worms and other creatures in turn eat the microbes. For microbiologists like myself, this motley crew of creatures is a precious sight, but not because I’m interested in studying them — it’s the tiny microbes I make these half-mile descents for.

Ever since I became a microbiologist, a series of questions has gnawed at me: Are there life-­forms hiding inside the Earth? And if there are, how do they survive? Would their nature be so strange that they change our conception of life itself? 

The major categories of visible life on Earth have been pretty much settled for centuries. But it wasn’t until the 1980s that scientists found “intraterrestrials” — microscopic organisms living in what the biogeochemist David Valentine calls a “microbial purgatory deep below the Earth’s surface.” Soon followed by other revelations of life inside Earth’s crust, these discoveries revealed that we had been missing major branches on the tree of life. Indeed, these microbes proved that our assumptions about the boundaries of life were wrong — and wildly so.

Scientists Find Evidence of Another Core Within Earth’s Center

The newly proposed layer might have a different structure from the rest of the inner core

Some scientists think that Earth's inner core is actually made up of two similar but distinct layers. 

By studying seismic waves from earthquakes, scientists have detected evidence of another core at the center of the Earth. They call this new layer, located at the heart of Earth’s inner core, the “innermost inner core.”

Earth’s inner core, a 1,500-mile-wide hot ball of metal, is still mysterious to scientists. Separated from the planet’s surface by thousands of miles of rock, it’s incredibly difficult to study.

“We strengthen existing evidence for the existence of the innermost inner core,” Pham tells Scientific American’s Stephanie Pappas.

The two proposed layers of Earth’s inner core appear to be similar—both are composed of an iron-nickel alloy—but they sport different crystal structures, per the Post. The transition between the inner and innermost cores seems gradual, Pham tells Reuters.
