A mysterious 'hole' larger than Maryland has reappeared in the middle of Antarctica after 42 years. Scientists aren't sure how it got there. But this isn't the first time it's appeared. The hole is a type of polynya. Polynyas are a region of open water surrounded by sea ice. But the Weddell polynya is unlike any other. While most polynyas form near the shore, this polynya is located hundreds of kilometers from the coast. Scientists first saw it in 1974. Back then, the opening was as large as Oregon. But in 1976, the opening closed up seemingly for good. Then, in 2016, a NASA satellite spotted a small opening. It was the first sighting of the polynya in over 40 years. Since then, the opening has grown considerably larger. Now, it's large enough to fit Maryland. It's still 5X smaller than it was in the '70s. But this polynya's reappearance is a mystery to scientists. One expert said it was like someone had punched a hole in the ice.

seems like a hole that serves as passage for the inner earth from the "hollow earth theory"

For the love of god somebody send a drone down there.

Whoever made this video left out the fact that in 1947 Richard Byrd actually flew over Antarctica and saw the same thing but he described it as an entrance to an hollow earth with green life inside

That’s the hole excavated when Megatron was discovered

Admiral Byrd was right.

So we can zoom in on bricks on a building from space and this is the best we can see? Yeah, right? lol

🤔For a million dollars how many of y'all going in there to see what's up???

The most interesting thing about Antarctica is how viciously they fought for and protect it. Its a large ring.

Well, Earl down at the corner 7-Eleven says it's where the aliens blast a hole in the ice so they can go back into space. Sounds legit.

They can tell us anything and we’ll accept it as true. That’s what got us in the situation we’re in right now. 🤦🏼‍♀️Question everything.

it's likely a spot that has a heat source below it, most likely volcanic. it's probable it was active during the late 60's and early 70's, and thus melted the ice around it, only to return to its 'dormant' state, getting the cold weather to turn the melted ice water back into ice, and as such 'disappeared'. It popping back up in the 2016's means likely the volcano was once again active in some sorts back then, perhaps less violently active than in the 70's, and as such disappearing again soon.

Ancient astronaut theorists say yes.
@stonedcoldchillerk7780 6年前

Can't it just be an underwater volcano melting the ice?
@TheGreatest1974 2年前

Do they know whether there are any active volcanic activity below the hole that could periodically melt the ice above it?
@billyken407 3年前

it might be a secret entrance for UFOs or underground aliens.

This is too funny, “let’s see what’s happening on Mars though”
