    • @BushelChaser If the symmetry is because of gravity, then still the shape of these planets should be modified, and the impact we should see, but so far none except the impacts that are caused by our own activities like climate change. What I mean, the life only on earth not on others, put me to speculate, that this planet is selected by a force especially for life. My idea is that, the whole universe is under a force and move simultaneously like the parts of an engine move. They are all connected and move in their own orbits and under dictation by a force, they keep moving on their own or around each other. The orbits are fixed, they cannot go away from those orbit, this is another indication that the symmetry is due to the symmetry of orbits. If the orbits were not fixed and not dictated by a force, then we would facing catastrophes and we were hit regularly. Day after night or night after day, or only days in some planets, or only nights in some planet indicate these universe is moving simultaneously because of a force.

    • @Aqleem Abbas when a star goes supernova all of the debris is spread out unevenly. After which it coalesces into planets of which are not in fact at all symmetrical. They are only round because of the force of gravity. Michio has developed his beliefs by fact and rationality. Who are you to say he's wrong and why do you believe what you believe.

    • I am against the theory of Prof. Michio Kaku, who suggests that life originated in space. The building blocks of life had come from extraterrestrial space. Then there are chances, that Mars and other planets will also have the building blocks of life. At least there should be those organisms that survive in a harsh anaerobic environment. The question is: Why building blocks of life become life only on the earth? We know the beginning of all the planets were the same because they are parts/debris of the same star. However, in modern telescopy, we saw that all the planets have perfect symmetrical geometry. What I think, this planet earth is selected by a force and the life which tolerate cold and heat by itself like animals, bacteria and fungi have originated here, and the life which cannot tolerate cold and heat and need clothes and coats like human have originated in another plant and then a force has dispatched them here and that force is God.

You have nothing to loose by just trying......oh and for the record, God sends all the plagues famine pestilence because we'll look what time it is....CLOSE TO HIS COMING IN THE CLOUDS WHERE WE ALL ARE CALLED UP CALLED THE RAPTURE

  • Science also has to admit where a virus comes from first before they can stop it or at least find a cure for it. One can't just bury their heads in the sand when faced with facts they would rather overlook such as lab created strains that mute faster and become deadlier once released either accidentally or on purpose.

  • If life on Earth did start through panspermia, those asteroids struck Earth at a time when Earth's atmosphere was not evolved and complex as it is now. Any celestial object that enters Earth's atmosphere will be subjected to extreme friction resulting in the generation of heat that will end up burning the object to the point of breaking it up. No microorganism will be able to survive that much amount of heat. If a microorganism does survive the heat it will be a miracle and will kickstart our adaptation to diseases in space which will help us survive during space travel.
