This discovery about where oceans come from proves how AMAZING the Earth really is

A team of geologists lead by Steven Jacobsen from Northwestern University has very recently made an astounding discovery—they've found a massive body of water near the core of the Earth!

The body of water is three times the size of any ocean on Earth’s surface. The geologists studied the speed of seismic waves to find out what lies beneath our planet’s surface.

When the waves reached a layer of blue rock called ringwoodite, they slowed down. This was an indication that they were passing through both water and rock.

This large body of water is 700 km below the Earth’s mantle. The mantle is the layer of hot rock underneath the surface. “Its good evidence earth’s water came from within,” Jacobsen told NewScientist.

Geologists have always wondered where the Earth’s oceans originated from. They questioned whether it seeped from somewhere within the planet or whether it arrived from somewhere else, like icy comets that collided with the planet.

The location of this newly discovered body of water places it at the perfect temperature and under the correct pressure to make it feasible that the water can ooze out of the ringwoodite to the surface in a way that, according to Jacobsen, is “almost as if it’s sweating."


Some scientists believe that the Ten Plagues of Egypt was caused by a singular, natural event that triggered the chain of events described in the Bible

There are various scientists who believe they can explain the occurrence of the ten plagues depicted in the book Exodus in the Bible, based on a singular natural event that caused a chain reaction of events.

According to Siro Igino Trevisanato it was caused by the Santorini volcanic eruption in Greece in 1602 B.C.

According to his theory, the ash from this massive eruption would have coated the Nile.

This would have been conducive for the growth of reddish freshwater algae known as Burgundy Blood algae that turns the water red when it dies. That would explain the first plague and this would have caused fish to die too.

With the fish dying, frogs would flee the water (second plague) and would end up dying too. Insects kept in check by frogs would rapidly increase and this would lead to the third plague.

This could explain the livestock diseases and the boils too, because the region is known to have biting flies and with nothing to control their numbers, it could have led to epidemics of associated diseases.

The hypothesis regarding the tenth plague is that the earth tremors caused by the eruption of Santorini allowed carbon dioxide and other toxic gases to escape the surface tension of the water in the Nile.

Being heavier than air, these gasses would "flood" the surrounding area displacing oxygen and killing those in their path. According to Simcha Jacobovici, the Egyptian firstborns slept on the ground and that would explain the tenth plague’s selectiveness.


There's a mysterious radio signal known as the 'space roar' throughout the universe that no one can explain!

In 2009, researchers searching for signals from the first generation of stars were surprised when their instruments were overwhelmed by a radio signal stronger than anyone could have expected.

Known as the 'space roar,' no one can explain where it comes from, and the signal is six times stronger than the combined emission of all known radio sources in the universe!

Before you grab your tin foil hat, there's no message in these radio waves. They are waves just like the ones your radio receives to play music, but there's no music to be heard with this "roar." The team that discovered it described the sound as a "boom" or a "hiss" when translated into sound.

This mysterious signal is actually preventing the team from doing what they set out to do: find signals from the first generation of stars.

This is because the signal is just so strong that their instruments can't pick up those much weaker signals. It's like trying to hear someone whispering to you while an air horn is going off next to you.


Some awesome lists!

If you try to grow an apple tree from an apple seed, there is a nearly 100% guarantee that the apples will be COMPLETELY different from the one that had the seed.

Planting apple seeds does not mean you’re going to get what you want. You might still get an apple tree, but it almost certainly won’t be the kind of apple tree from which the seed came from.

This is because seedling apples are an example of what’s called “extreme heterozygotes,” meaning that rather than inheriting DNA from their parents to create a new apple with those characteristics, they are instead significantly different from their parents.

Of course, there are apple orchards that contain only one type of apple tree, so there must be a way to get the kind of tree that you want. This is true, and it’s done through a process called grafting.

Grafting is a horticultural technique whereby tissues from one plant are inserted into those of another so that the two sets of vascular tissues may join together.

Another way to think of this is the root providing the scaffolding for the plant, while the other plant’s characteristics are put on top of that to make the kind of tree you want.

Grafting allows growers to choose pretty exact characteristics for their trees. The rootstock used for the bottom of the graft can be selected to produce trees of a large variety of sizes, as well as changing the winter hardiness, insect and disease resistance, and soil preference of the resulting tree.


There was a time when a cleaning lady was one of only two people to know the sun was not near the center of the Milky Way!

Harlow Shapley was an American astronomer who lived from 1885 to 1972. His effect on science isn’t widely known outside of scientific circles, but he certainly had a great one.

He was one of the first to suggest the habitable or goldilocks zone for planets which he called the “liquid water belt.” But what he is most known for is correctly estimating the size of the Milky Way and the sun’s place within it.

This great accomplishment came when Shapley was working to determine distances to globular clusters under a fellowship at Princeton.

The discovery came when he was working late one night. He was so excited that he knew he had to share it with someone, so he found the only other person in the building: a cleaning lady.

The two stood looking at his graph as he explained that they were the only two people on Earth who understood that humanity lives, not near the center of a small star system, but in the suburbs of a vast wheel of stars.
