To add to this, two out of three of Nasa's proposed deflection strategies, firing nuclear bombs at an asteroid heading towards Earth, or trying to change its course using the
gravitational force of a space craft, would not work according to a panel of experts from campaign group World Asteroid Day. It is believed that hitting a major asteroid with a nuclear bomb
would simply cause it to blow into smaller fragments that would rain down on earth, increasing the area of impact. Scientists also fear we would not have a spaceship large enough to knock
even a huge asteroid of course if it was heading to earth, so there is little that could be done to affect the path of a planet. Nasa itself believes it may be possible to destroy one if it
was far enough away when the warhead struck. They have been investigating how to use nuclear bombs to deflect comets, asteroids and meteors. But Nasa is confident it still has time to
develop its deflection strategy. Nasa scientist Jason Kessler, who runs the 'near Earth" asteroid programme, said: "The likelihood of something hitting us in the future is
pretty guaranteed, although we're not freaking out that there is an imminent threat." The US space agency is confident there are no large asteroids on course for Earth anything
soon. A Nasa spokesman said: "Nasa knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small. "In fact, as
best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years." But online forums are awash with debate about Nibiru. YouTube by Sky
Watcher Matt Rogers, a conspiracy theorist who scours the sky for evidence of Nibiru claims in a new video that world leaders know Nibiru is coming, and we are all doomed, but they are
keeping it from the public to prevent panic, as they wait to hide in underground bunkers. Mr Rogers, who is based in the UK, said: "NASA has covered it up. The Government shut it down
to prevent mass panic, but it is coming, this is fact." There is, of course, no evidence to back up his claims.
