    Earth Impact
AI Thread Summary
Apophis, a 300-meter asteroid, is set to make a close approach to Earth on April 13, 2029, but current assessments indicate it will not collide with the planet. However, if it passes through a specific "keyhole" during this flyby, it could be on a collision course for 2036. Experts suggest that deflecting the asteroid before 2029 is crucial to avoid this potential impact, as breaking it apart could lead to more widespread damage. The discussion highlights various deflection strategies, including the use of nuclear devices to alter its orbit rather than fragmenting it. Overall, while the risk of collision exists, proactive measures can mitigate the threat posed by Apophis.

I think the Giant Solar Laser (see https://www.physicsforums.com/showthread.php?t=174052") is that very tool for deflecting Apophis. I think such solar lasers could be used not only for deflecting asteroids, but for deflecting planets, e.g. for to move Mars to Earth's orbit and then to implant the Earth-type life to it. Colonizing Mars, isn't it a good prospect for all of us?

This is just speculation-- you point to a thread about a "giant solar laser" which firstly, has no details, and secondly has been locked due to idle speculation! I suggest that you should give up trying to publicise your "idea" on here.

Please, tell me what's wrong with my idea? It doesn't contradict any existing knowledge about lasers. Filling it with details is not my job since I can't build such a laser in my kitchen for to test it.

I can't tell you what's wrong with your idea, since I know no details about it. But, please don't start telling us here; firstly, it will be off topic trying to describe such an idea, but secondly, and more importantly, it is an idea and, as such, belongs only in the independent research subforum (as explained to you in your last thread which was subsequently locked).

You really have to stop trying to bring up topics from threads that have been locked again and again.

...NASA had previously estimated the chances at only 1 in 45,000 but told its sister organisation, the European Space Agency (ESA), that the young whizzkid had got it right.

The schoolboy took into consideration the risk of Apophis running into one or more of the 40,000 satellites orbiting Earth during its path close to the planet on April 13 2029. [continued]
