1.5 billion-year-old Earth may of had water everywhere

    What did Earth look like 3.2 billion years ago? New evidence suggests the planet was covered by a vast ocean and had no continents at all. They found clues about this ancient Waterworld preserved in a chunk of ancient seafloor, now located in the outback of northwestern Australia. Its rocky scenery preserves a hydrothermal system dating to 3.2 billion years ago and records the entire ocean crust from the surface down to the heat engine that drove circulation. It also showed different types of isotopes of oxygen over time. And the ratio between these oxygen isotopes hinted that at the time, there were no continents at all.

    I find it interesting because when you said, "ancient waterworld" it made me think of Atlantis, it is also crazy to think that with our technology now we can see that far into the past about the ocean, but we know very little about the life inside of it.

Over 87,000 papers published on coronavirus since start of pandemic

 Over 87,000 papers have been published about this global pandemic. When most people think of the pandemic going around right now, they think about how awful it all is. How many people have died, how many people have lost a family member, or how many people they have lost relationships with friends or family. But, do people ever think about how this event will go down in history, and how it will affect science studies in the future? We never know what type of science we will come across in the future, but we can say that science evolves every day, and things are constantly changing. This is why so many people are interested in this pandemic. The more we know about this pandemic, the more we can do to try and change is. So, what will science bring in the future? And how will it impact future in sciences? We won't know the answer to either of those questions for a long time, but we can certainly say that it will evolve so much, and make things a lot more interesting.    htt...
