What would happen if a hydrogen bomb exploded on Jupiter?
Hydrogen bombs do not work by any chain reaction. They work by compressing hydrogen so strongly that nuclear fusion takes place. Only a tiny fraction of the hydrogen in the bomb actually fuses, and the energy released then causes a massive explosion that blows away the rest of the hydrogen, the rest of the bomb, and anything else within a couple of miles. If you dropped one on Jupiter there would be a big bang and that't it. You don't initiate fusion by dropping a bomb into a mass of hydrogen and blowing it up. All that will do is disperse the hydrogen. You need to conatain and compress it to cause fusion. If Jupiter was capable of fusing hydrogen at all it would already be doing so. Stars do it under the pressure of their own mass compressing the core so strongly that fusion can occur. They are not fusing anything in the outer regions. Perhaps more to the point, Jupiter is absolutely HUGE. Every single explosive device we have ever made in the whole history of mankind would barely make a dent in it, much less initiate any kind of fusion reaction. Only in sci-fi can anything as small as humanity affect something the size of a gas giant so devastatingly.
If the Moon exploded, would we hear it?
First sound does not travel in space as others have pointed out. However the parts about hearing the pieces fall to the earth is up for debate. If an explosion was big enough to explode the whole moon it would probably send off large chunks at speeds much faster than the speed of sound. If any of those large chunks made it though the atmosphere they would be traveling faster than we could hear them. If you were close enough to even hear it in theory you would probably be dead before you could. You may see the coming force of the impact destroying all life within a given radius, dependent upon the size of the impact.
What would happen if Jupiter Explodes?
The comet Shoemaker-Levy might have had set it off if it replaced into best and arranged. Our bombs does no longer carry a candle to that! Beside, the bombs does no longer help, as a results of fact that fusion ignition demands best gravity to offer the rigidity mandatory on the middle, the bomb might merely explodes on the exterior, or no longer far from it. Jupiter heavily isn't an excellent call. on the different hand, what may be a sight if Jupiter replaced right into an excellent call. i ask your self whether Earth might nonetheless be the comparable, and whether or no longer all different Jovian planets may be striped bare of their gaseous masking and lay bare of their (perhaps) reliable cores.
What would happen to our solar system if Jupiter exploded? Would you be scared even if it didn't affect us?
If Jupiter suddenly wasn't there anymore, there would be no detectable ill effects. In the long term, we might be at an increased risk of getting hit by a comet without Jupiter to act as a great big gravitational target to get hit instead. If you could somehow start sustained fusion reactions in Jupiter, turning it into a mini star like in 2010, the only effect on earth would be a really, really bright star in the sky. There's no known way this could happen, however. Jupiter is far too small to sustain fusion. If jupiter actually exploded (as in, boom and nothing left), what happens to us depends on the method of the explosion. Planets don't explode - the gravitational binding energy of something the size of Jupiter is well beyond the capability of any mundane chemical or nuclear process to overwhelm. To make Jupiter actually explode would take something really exotic, like throwing a moon made of antimatter at it, or somehow converting the core of Jupiter into neutronium. In that case the results for everyone in the solar system could be bad, as the process would probably liberate a vast amount of radiation - effectively a mini supernova. Everything on the side of the planet not facing Jupiter would probably survive for a while.
What would happen if the moon exploded?
Watch the end of the movie called Tycus ( 1998 ) and watch as descendants of the survivors look up into the sky after 100 years after the moon had been destroyed for an idea of how some people think the sky would have changed.
1. You will know about the explosion only after about 8 minutes.Eg. If the Sun explodes at 00:00 hrs., it will disappear from our sky after only about 8 minutes.2. Depending on the intensity of the explosion, a massive amount of energy & hydrogen + Helium gas mixture will be released along with a shock wave.3. The resulting release of energy will destroy all our satellites on the bright side of the planet & affect our planet adversely.4. If somehow we are able to survive the burst of gases & energy, due to lack of the light & heat, plants will die, the planet will cool down excessively & majority raves of the planet will die. Unless some organisms are able to evolve (which I doubt, due to lack of proper time for evolution), all life will eventually perish due to excessive coping of the planet or lack of oxygen or the resulting shock wave that will ripple through the food chain & climatic cycles.
answer is quite simple , look earth when originated from nebula was heated up and was not of the shape it is now , it was in some kind of irregular shape ,but even at that time it had magma in it's core ,heated up earth was attracted by magma due it's gravitational pull {f=GMm/r^2} gradually it attained the shape it has now :since all matter on earth has the tendency to attain stablest state .sphere was right answer {atoms don't have brain even then earth is quite a lot spherical in shape appreciate it:) }though some parts did wither off . entropy of matter on earth started decreasing {which is just a fancy way of saying earth cooled down }. interparticle forces of this giant ball increased which could not be broken down by low external pressure. (compare it with why space crafts don't break apart in low pressure .imagine jupiter which is a ball of gas and is held together due to it's core's gravitational field basically earth attained the stablest state in it's childhood.
I would buy thousands of microwave ovens, dismantle them and remove the magnetron inside. I would wire up the magnetrons to a pulse motor which would be controlled by PLC controller and an HMI interface. I would develop a data model which assigns wave frequencies to a three dimensional particle grid. I would break into a nearby national laboratory and steal an EHF sensor/scanner. I would then assign each particle on the grid to a frequency based on the ehf scan assignment. Once I have the wave form of myself in the system, I would hook up the frequency graph to a very powerful sound signal amplifier which emits electromagnetic millimeter waves. I would kiss goodbye to the nice hydrogen bonds in my dna and point my jury-rigged dish at Mars. I would splat my mush wave on Mars and sit there like a strange aimless wave floating around Mars for probably a billion years. But then I guess maybe something cool might happen someday.Update:It has been a few months since I wrote this and the doomsday clock is closer to midnight than it has been in over fifty years. Several commentors have pointed out some technical complications with my theories and I respect them, so I would like to post those limitations here so somebody smarter than me can solve it. To get the oscillations required to densely populate a pixel grid, you need above ghz range at nano scale. The reason we need to weave so fast is because we need to bind the particles using electron magnetism, so we need to tag them before they get away. This limitation is quickly being solved and recently some tests showed oscillations as high as 1.6ghz. So we’re quickly solving these and hopefully before the end.Also, one clarification: We use a sonic horn to resonate the particles, helping them keep shape and also establishing their frequency before the magnetic field reaches phase transition.
What would happen if the moon explodes?
Your question depends on certain assumptions. If the moon were to explode and simply disintegrate, with no chunks raining down on the earth, then the effects on the earth would be entirely gravitational -- assuming the moon dispersed out into the solar system, the earth-moon system's center of gravity would change, possibly adding a bit of a wobble to earth's orbit around the sun. Also, the tides would be affected, because there wouldn't be the cyclical pull of the moon on the mass of the oceans any more. If the moon were to literally explode, of course, parts of it would indeed fall to earth, and depending on how powerful the explosion, some of the chunks would probably be large enough to cause what astronomers rather perspicaciously call an "Extinction Level Event" i.e. kill all life on earth, on a scale that would make whatever killed off the dinosaurs look like a minor scratch.
