प्रश्न
What’s the solution?
One of the asteroids has fallen out of its place in the asteroid belt and is hurtling towards the sun. Our earth is in its way and there is all likelihood of a collision. What can be done to prevent this collision?
उत्तर
- The first act to save the earth can be attacking the asteroid with the help of a missile. A missile can break an asteroid into smaller pieces.
- The second way is to change the path of an advancing asteroid. For changing the path of the asteroid, a spaceship or missile can be used to push the asteroid aside. Space shuttles fitted with mirrors can be used. so that the reflected sunrays from such mirrors can be bombarded on the asteroid. This will create pressure on the asteroid and its advancing path can be changed.
- By use of laser rays. the surface of an asteroid can be subjected to evaporation. This will create a change in the mass of the asteroid. We can also send extra material on the asteroid from the earth. Such a change in the mass of an asteroid changes the orbit and the path of the asteroid.
- By placing a space shuttle in the vicinity of this asteroid, the gravitational force could be created. This can also change the speed and path of the asteroid. Astronomy and astrophysics are so advanced now that even if such a threat exists in the future, we can easily protect our earth inhabitants well in advance.
