Megatsunami and The Wave (movie)

2015 Norwegian catastrophe drama film The Wave tells a fictional story about Geiranger, a small tourist village in Sunnmøre region of Møre og Romsdal county in the western part of Norway. In the movie, the village threatened a huge mass of rock tumbles into Geirangerfjord (which is one of Norway’s most visited tourist sites, and it was listed as a UNESCO World Heritage Site in 2005). The rock sets off a 300 feet megatsunami. The villagers must rush to the mountains in ten minutes, before “the wave” reaches them.

Here is the trailer of the movie. Directed by Roar Uthaug (born 25 August 1973), it was Norway’s official submission for the Academy Award for Best Foreign Language Film at the 88th Academy Awards but it was not nominated.

The World entered a new geological era called “Anthropocene”, scientists say

According to a study titled “The Anthropocene is functionally and stratigraphically distinct from the Holocene” and published on Science Magazine, we, humans, changed the world so much that now we can say the world entered a completely a new geological era, “Anthropocene”.

The term is not new. As early as 1960s, Soviet scientists used the term to refer to the Quaternary, the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). The Quaternary follows the Neogene Period and spans from 2.588 ± 0.005 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.588 million years ago to 11.7 thousand years ago, the world’s recent period of repeated glaciations) and the Holocene (11.7 thousand years ago to today, began after the last major ice age).

If Earth’s life time was the distance from Los Angeles to New York City

Our old planet, the Earth is 4.54 billion years old. In fact, the human mind can no longer make any sense of large numbers like that. Numbers like 1, 2, 14, 20, 50 are all quantities that we encounter quite frequently in our daily lives. And our brain evolved to conceptualize numbers like that: our ancestors saw two lions; they hunted five deer in one hunting party, the population of their tribe was 20, etc… But when the numbers are getting big, i.e. 1,000; 10,000… the problem begins: these numbers become increasingly difficult to conceptualize. Now, what happens when we try to conceptualize quantities like billions, like the Earth’s age? We can’t actually rationalize the immensity of such a big number. Because we haven’t a model of 4.54 billion that’s been compressed into something recognizable to the human mind.

To put this number into a perspective, Alex Kuzoian of Business insider prepared a beautiful video: you can watch Earth’s lifespan as the distance from Los Angeles to New York City. Along the trip, we see the formation of our Moon, the beginning of the life, the evolving of the multi-cellular organisms, and the rise and fall of the dinosaurs. Probably the most interesting part is that modern humans only evolved 175 meters (570 feet) from the finishing line of this journey. And the big jump to the first multi-cellular organisms.

Timeless Dreams – the Earth in daytime and nighttime

You must watch this! An amazing video by the filmmakers led by Julian Tryba: in May 2015, over the span of three weeks, they traveled in the Southwest of the United States (3,000 miles through Utah, Arizona, Nevada, and California) and filmed timelapses of several strikingly beautiful landscapes. Then they spliced the films together to create this wonderful video, a strange day-night world.

Your Life On Earth (presented by BBC)

A nice interactive webpage by the BBC – The British Broadcasting Corporation: how you and the world have changed since you were born? You’re simply entering your birth date, gender, and height; selecting units (metric or imperial/US) and then watching how our planet (and you) has changed in your lifetime.

No! The Earth Would NOT Look Like This Without Water

No, no no, and again: no! The Earth would NOT look like this without water. Please stop sharing this nonsense.

Here some numbers: the Earth has a diameter of about 12,735 kilometers (on average). The highest point on Earth is the top of Mt. Everest, at 8.85 km. The deepest point on Earth is the Mariana Trench, at about 11 km deep. Make the calculations and you can see, the Earth definitely would NOT look like below without water:

Vulcan Points

Can you imagine an island within a lake that is situated on an island located in a lake on an island? Confused? Well, it is really confusing, but this island does indeed exist: Vulcan Points is the world’s largest island within a lake (Crater Lake) that is situated on an island (Taal Volcano Island) located in a lake (Lake Taal) within an island (Luzon).

Can you see the tiny blue shadow in the south of Manila, the capital city of the Philippines? (In the northernmost island, or Luzon Island.)

The deepest lake in the World: Lake Baikal

The world’s deepest lake is the Lake Baikal, which has a depth of 1,642 meters (5,387 feet). It is a rift lake in the south of the Russian region of Siberia. Its bottom is at 4,215 feet (1,285 meters) below the sea level. In terms of volume, Lake Baikal is also the world’s largest freshwater lake; it contains roughly 20% of the world’s unfrozen surface fresh water with 23,615.39 cubic kilometers (5,700 cubic miles). It contains more water than that of all the North American Great Lakes combined.
