What did Ancient Earth Look Like

I stumbled upon an amazing web page showing what did ancient Earth look like. On “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient Earth did look like then. You can also remove the clouds and stop the Earth’s rotation if you want to.

The Earth is 18 Galactic Years Old

How old is the Earth? This question preoccupied first philosophers, then scientists, for many centuries. Today, we know that the age of the Earth is approximately 4.54 billion years, with an error range of about 50 million years (4.54 × 109years ± 1%). This number is based on evidence from radiometric dating of the oldest-known terrestrial rocks as well as lunar rock samplesNotes 1 and meteorites.

The hottest place in the Universe exists on Earth

The hottest place in the Universe exists here on Earth, like the coldest place in the Universe. Both these extreme temperatures are not natural, they are human-made. The coldest temperature was achieved in the German physicist and professor of physics Wolfgang Ketterle’s laboratory at the Massachusetts Institute of Technology (MIT). The hottest temperature, also recognized by the Guinness Book of World Records, was achieved at CERN’s Large Hadron Collider (LHC).

The coldest place in the Universe exists on Earth

It may sound strange, but the coldest place in the Universe is not anywhere in the vast, cold outer space – it exists here on Earth. Well, it is not actually a natural place you can come across. It is in a laboratory in M.I.T. (Massachusetts Institute of Technology).

Point Nemo – The Spacecraft Graveyard

In the middle of the South Pacific Ocean, there’s a location called “Point Nemo”. It’s not a place that humans live – in fact, there is no land there – not an island, not even a small rock. It is actually the remotest place from any human civilization you can find on Earth. It lies at least 2,688 km (1,670 mi) from the nearest land. It is also called “Oceanic pole of inaccessibility”.Notes 1

Animation – Earthquakes Between 2001 and 2015

The American scientific agency within the United States Department of Commerce, National Oceanic and Atmospheric Administration (NOAA) published an animation on youtube showing the Earthquakes of the First 15 Years of the 21st Century (between January 1, 2001 and December 31, 2015). The animation shows every recorded earthquake in sequence as they occurred at a rate of 30 days per second. It is based on the new SOS dataset of all the earthquakes in that period from the US NWS Pacific Tsunami Warning Center.

Why Do We See Only One Side of the Moon?

You have probably heard references made to the “dark side” of the Moon – there’s even a Pink Floyd album with that name. But, in fact, there’s no “dark side” of the moon. Because it is not illuminated by the Earth, it is illuminated by the Sun. All the surface of the moon lit by the Sun as the Moon rotates.
