Meade told a news portal this month, "The Great American Eclipse of August 21, 2017, is a major - huge - harbinger".
Nasa said that none of these theories are true.
The agency said if Nibiru were headed for an encounter with the Earth, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. They believe "it" to be the ultimate destroyer of the life-supporting planet earth.
According to the Christian numerologist, David Meade, August 21, 2017, the day when Total Solar Eclipse occurs is seen as an exciting event but in reality is a warning of the destructive future. During this period, Moon will get ahead of the sun, in front of it, which will cast a complete darkness across bandages of the Earth's surface.
Diameter-wise, the sun is about 400 times the size of the moon, and the distance of the moon from the sun is about 400 times the distance of the moon from the earth.
He said there was a stunning numerical coincidence that he calls the "33 Convergence".
And just before this monumental occurrence, sky-gazers in America will be treated to a total eclipse. In the Bible, the divine name of Elohim appears 33 times in Genesis.
But a lot of people actually put stock into this concealed world - and have developed cold feet that the looming "Great American Eclipse" would mark its arrival. Regardless of having no substantial evidence, David Meade along with some other conspiracy theorists has argued that Bible passages, as well as the presence of the total solar eclipse, completely shore up the idea that the end time for the earth is inching closer.
That date is September 23, 2017, he says.
He added: "This is indeed an fantastic omen and a frightful sign". To further reaffirm this, they believe that the coming solar eclipse will call for the apocalypse. Reverend Donna Larson, who runs the blog Rapture and End Times, also warned the world will end this year - as did Robert Binnion, who runs the "end of time prophecy website" Nice Timing.
Paul Begley, a pastor at the Community Gospel Baptist Church in Knox, Ind., maintains a YouTube channel with more than 190,000 subscribers.
"Images and data from potentially as many as millions of people will be collected and analysed by scientists for years to come", Carrie Black from the US National Science Foundation said last month.
The stories of Nibiru causing apocalypse has been mostly brushed aside as a mythical, fascinating story. Dan McGlaun, who runs the website Eclipse2017.org, wrote: "Total eclipses are so phenomenal and so overpowering and so wonderful that some people have ascribed a "super spirituality" to them".
"Fortunately many astronomy-related conspiracy theories fall into the harmless nonsense category, but there are occasional grim exceptions, like the Heaven's Gate cult".
