The earth WILL ultimately be destroyed, this is accepted as a fact by astronomers. The fate of the earth is linked to the fate of the sun. The sun is a main sequence yellow dwarf star. This means it is in the longest phase of its life - fusing hydrogen into helium, which will has been going on for almost 5 billion years. It is about half way through this phase. When it is over, it will expand, becoming a red giant. It will be far hotter than it is now, and its outer surface will extend beyond earth's current orbit. If the earth stays where it is, it will be consumed by the sun. If the earth drifts to a more remote orbit it will lose its water and atmosphere first. No matter what happens at this point, a red giant sun will only last a few million years, before becoming a very cool, tiny, white dwarf. This star will simply dissipate its heat and not be sufficient to sustain life.

If you mean can it be destroyed by collision with another object - it probably could, but it hasn't in the last 4.5 billion years, so probably will survive. That said, a catastrophic collision event occurs roughly every 500 million years, and one is overdue by many millions of years. Such an event could cause a mass extinction, like that which killed the dinosaurs.

Earth hard destroy, life on it not so hard, several time, most life extinct.

It would take a lot to physically destroy the planet, but it would take significantly less if you're just out to destroy it's ability to sustain life.

Not easily really, though life could be destroyed if a large enough asteroid hit us. Something quite a bit bigger than the one that made the dinosaurs extinct would probably get us as well.

There's no chance we'll do it with a particle accelerator. Any particles created would be so unstable and short-lived to make no difference at all.

Bear in mind that the upper atmosphere is being continuously bombarded by much more energetic particles than we could ever produce in an accelerator, and nothing created from those has led to our doom so far...

1.) Gobbled up by strangelets

Method: Hijack control of a particle accelerator. I suggest the Relativistic Heavy Ion Collider in Brookhaven National Laboratory, Long Island, New York. Use the RHIC to create a strangelet large enough to remain stable. Once created, your job is done: relax and wait as the strangelet plummets through to the Earth's core, where it will eventually swallow up the entire Earth.


2.) Sucked into a microscopic black hole

Method: simply place your black hole on the surface of the Earth and wait. Black holes are of such high density that they pass through ordinary matter like a stone through the air. The black hole will plummet through the ground, eating its way to the centre of the Earth and all the way through to the other side: then, it'll oscillate back, over and over like a matter-absorbing pendulum. Eventually it will come to rest at the core, having absorbed enough matter to slow it down. Then you just need to wait, while it sits and consumes matter until the whole Earth is gone.


3.) Overspin

Method: The theory is, if you spin the Earth fast enough, it'll fly apart as the bits at the Equator start moving fast enough to overcome gravity. To do this the Earth will need to be spinning very fast indeed. Currently it rotates completely on its axis once every 24 hours. You'll need to spin it fast enough to perform a complete rotation once every 84 minutes


4.) Destroyed through Matter / Antimatter reaction.

Method: This method involves detonating a bomb so big that it blasts the Earth to pieces.

This, to say the least, requires a big bomb. All the explosives mankind has ever created, nuclear or non-, gathered together and detonated simultaneously, would make a significant crater and wreck the planet's ecosystem, but barely scratch the surface of the planet. There is evidence that in the past, asteroids have hit the Earth with the explosive yield of five billion Hiroshima bombs - and such evidence is difficult to find. It is, in short, insanely difficult to significantly alter the Earth's structure with explosives. This is not to mention the gravity problem. Just because you blasted the Earth apart doesn't mean you blasted it apart for good. If you don't blast it hard enough, the pieces will fall back together again under mutual gravitational attraction, and Earth, like the liquid metal Terminator, will reform from its shattered shards. You have to blow the Earth up hard enough to overcome that attraction.

Hello ,

Well on of them is LHC ( Large Hadron Collider ) : it's an Experiment Located in Switzerland in Cern Nuclear Research if this Experiment Worked it may Create Microscopic Black Holes Witch won't take few minutes even Seconds to destroy Earth and maybe the whole solar system.


Best Regards
