See my copyright notice for fair use practices. The Earth’s lithosphere is broken up into chunks called plates with densities around 3. Oceanic crust is only about 6 kilometers thick. The continental plates are made of another volcanic type of silicates called granite. Continental crust is much thicker than oceanic crust up to 35 kilometers thick. Continental plates are less dense than the oceanic plates.

Then, on October 6, , Michel Mayor and Didier Queloz of the Geneva Observatory announced the first definitive detection of an exoplanet orbiting an ordinary main-sequence star 51 Pegasi. Many known extrasolar planets are many times the mass of Jupiter, approaching that of stellar objects known as brown dwarfs. Brown dwarfs are generally considered stars due to their ability to fuse deuterium , a heavier isotope of hydrogen.

Although objects more massive than 75 times that of Jupiter fuse hydrogen, objects of only 13 Jupiter masses can fuse deuterium.

Planet X, or Nibiru, refers to a mythological planet in our solar system that will supposedly crash into Earth and wipe out the human race, however it has been consistently dismissed by Nasa and other experts as an internet hoax. Despite absolutely no scientific evidence to back up the suggestions of a rogue planet getting rapidly closer to Earth, myths about Planet X continue to be perpetuated online. End of the world 23 Sept Of course, this isn’t the first time time harbingers of doom have predicted the end of time; Nasa also had to deny the existence of Nibiru in Throughout history there have been similar claims, but thankfully none of them so far have been proved correct.

How did conspiracy theories about Planet X start? Online chatter about Nibiru began back in when Wisconsin native Nancy Lieder created the alien-conspiracy website ZetaTalk.

Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War. The Talmudic rabbis, Martin Luther and others used the biblical account to extrapolate back from known history and came up with rather similar estimates for when the earth came into being. Within decades observation began overtaking such thinking.

In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata. He inferred that where the layers are not horizontal, they must have been tilted since their deposition and noted that different strata contain different kinds of fossil. This position came to be known as uniformitarianism, but within it we must distinguish between uniformity of natural law which nearly all of us would accept and the increasingly questionable assumptions of uniformity of process, uniformity of rate and uniformity of outcome.

That is the background to the intellectual drama being played out in this series of papers. It is a drama consisting of a prologue and three acts, complex characters, and no clear heroes or villains. We, of course, know the final outcome, but we should not let that influence our appreciation of the story as it unfolds. Even less should we let that knowledge influence our judgment of the players, acting as they did in their own time, constrained by the concepts and data then available.

One outstanding feature of this drama is the role played by those who themselves were not, or not exclusively, geologists. Most notable is William Thomson, ennobled to become Lord Kelvin in , whose theories make up an entire section of this collection.

Planet Niburu: What’s going to happen on September 23?

The prophecy is based on Christian numerology, and could be supported by several scriptures, depending on how you interpret them. According to one interpretation, the end of times will be brought about by a collision between Earth and the massive planet Niburu. Although now, reports suggest Niburu will not collide with the Earth, but pass close by, still disrupting life as we know it. The only problem with these prophecies and reports is that they are entirely baseless.

Planet Niburu does not exist and Christian numerology has never produced an accurate, reliable prediction.

Covering islands, mountains, jungles, deserts, grasslands, and cities, “Planet Earth II” literally covers a lot of ground in its seven episodes (the final episode is a “making of”), always with an eye toward beauty and our quickly changing s: K.

David Meade, author of the book ‘Planet X — The Arrival’, believes a star, which he calls ‘a binary twin of our sun’, is coming ‘at us towards the south pole’. He says the star will bring with it ‘seven orbiting bodies’, including Nibiru, a large, blue planet that he also refers to as Planet X hurtling towards our planet. Nibiru, sometimes referred to as Planet X, is a hypothesised planet on the edge of our solar system. Nibiru is a different planet to the Planet Nine, which is also sometimes referred to as Planet X, that was proposed by astronomers in Caltech in January last year.

Conspiracy theorists believe the gravitational influence of the ‘rogue planet’ Nibiru disrupted the orbits of other planets hundreds of years ago. They claim the next disruptive passage into the inner solar system could happen at any time. Some claims that this ‘planet’ is sending ‘plasmatic energy particles’ through our solar system. The flow of energy will disrupt the ‘core flows’ of the Earth and trigger catastrophic changes in Earth’s climate.

They claim, since , we have already been feeling the disruptive effects of the inbound rogue Planet X. Conspiracy theorists often blame natural disasters and freak weather patterns on the planet. David Meade believes the planet is set to hit into our planet in October this year, after being driven here by the gravitational pull from a ‘binary star’ twinned with the sun – of which there is no evidence. He says the star is difficult to spot because of the angle it is approaching Earth.

Using radiometric dating methods to determine the age of rocks means scientists have to rely on when the rock was initially formed (as in – when its internal minerals first cooled). In the infancy of our home planet the entire earth was molten rock – a magma ocean.

As it’s radioactive, the levels of carbon in the material decreases as it ages but the amount of the stable carbon doesn’t change. Therefore by looking at the ratio of carbon and radioactive carbon we can date the material. Radiocarbon dating is an extremely accurate and useful tool to date an archaeological find that contains any previously living material. It then separates just the carbon from all the other interfering particles, rather like a large sieve.

The way it does that is by particle acceleration, by beam bending the particles so that they can be separated by magnetic forces. The problem that we have though is that only a tiny amount of that carbon is carbon One particle in a billion, billion is carbon

Planet Niburu: What’s going to happen on September 23?

While they are built to find their own way safely to the sea after hatching, the programme showed how the brights lights of buildings along the beachfront were causing turtles to turn around and crawl in the wrong direction. Four in every five hawksbill babies, according to Sir David, who narrates the show, failed to make it through their first night after becoming disoriented, falling down drains and being crushed by cars.

Every turtle that was seen or filmed by the PlanetEarth2 crew was collected and put back into the sea. Sir David said last year: If I feel my presence is tilting the balance of the predator or the prey, then I’m doing something wrong. Speaking about the scenes depicted in the documentary series Africa last year, the broadcaster admitted:

Jupiter, at Earth masses, is the largest planet in the Solar System, and Saturn is one third as massive, at 95 Earth masses. Ice giants, Uranus and Neptune, are primarily composed of low-boiling-point materials such as water, methane, and ammonia, with thick atmospheres of hydrogen and helium.

Inform students that they are going to work as a class to create a time line of life on Earth. Assign one of the following organisms to each student, or have students work with partners and assign one organism to each pair: Instruct students to use the research materials you have provided or the Internet to answer the question, “How many years ago did your organism first appear on Earth? Distribute index cards to students, and have them use markers to write on the index cards the names of their organisms and the approximate number of years ago they appeared on Earth for example, “bacteria—3.

Instruct students to include simple line drawings of their organisms on the cards. They may draw microscopic organisms, such as bacteria, as if seen under the lens of a microscope. Use narrow paper to create a frieze going around all four walls of your room, explaining that students will use the frieze to create their time line. Elicit from students that the time line is so long because Earth is estimated to be 4.

Here is one way to divide the time line: Divide the fourth wall into tenths, each tenth representing one hundred million years. Explain to the students that the scale is not exactly correct, but the numbers are so large that it will give them a good idea of relative time periods. Have students tape their index cards to the appropriate part of the time line.
