The doomsday theories have been a constant subplot in Science. Starting from famous scientists like Sir Isaac Newton predicting that humanity would be wiped out by 2060 to the latest Nibiru and the Planet X predictions made by David Meade, a Christian numerologist, the end of Earth has always held our fascination and fear.

According to a report published by Forbes on Sunday, the predictions from Christian prognosticator — that he has put out on his website — say that Nibiru or Planet-X was supposed to collide with Earth on Sept. 23.

The Sun also published a report the same day, which said that “his ridiculous prediction, based on hidden numerical codes supposedly hidden within the Bible, failed to happen." According to the publication, this prompted him to change his initial claims to a seven-year process that would destroy the planet.

Meade was quoted as saying in that people misunderstood his prophecy of the Planet Nibiru colliding with Earth. He changed his prediction and said that “doomsday will take place over a period of seven years starting in October.”

On his website, Meade says the whole process will start Oct. 15. He claims the seven-year-long destruction of Earth would happen through solar flares, nuclear war, and natural disaster.

NASA scientists have come out in the past to try and assure people that science shows us that these predictions are not possible. A video uploaded on Youtube in 2011, by the Solar System Exploration Research Virtual Institute of NASA Lunar Science Institute Scientist David Morrison, lays down scientific reasons to why Nibiru is not real and does not pose danger.

This reaction came after NASA received a letter from a 12-year-old girl, which said her classmates were scared of Nibiru and its predicted deadly effects on our planet.

Science news website published a report in June that indicated the presence of planetary masses in the far reaches of the Kuiper belt just outside our solar system.

But this is not the same as the planet that could allegedly crash into or pass near Earth, says the Forbes report. "My book Planet X – The 2017 Arrival has the detail. You don’t have long to read it," reads an excerpt on Meade's website. According to the report, the claims are not true.

It says that this theory is not based on "actual science and critical thought” but is a loose theory which takes only examples through time that support the claim. This is compared to a conformation bias, where you choose the evidence which will only further your argument rather than seeing the entire picture, which might offer a simpler explanation.

More importantly, these theories choose to ignore is the power of modern-day science. Another report by Forbes says that we have telescopes powerful enough to detect an object as large as the alleged Nibiru planet. If there is a planet as large as Nibiru out there, “it should reflect enough sunlight that even from the ground, even at some five times the distance of Pluto, our telescopes should be able to see it,” the report underlines.
