Was watching the NGC this morning and the program that was showing was talking about how Earth could be destroyed such as a black hole, the Sun etc. Well one way was an antimatter bomb. Now obviously it would be extremely difficult seeing how the antimatter would have to be transported via a vacuum of some sort and it could not touch anything, even air. The bomb would have to be immense size around the range of 2 and a half tons. Now let's say the bomb was around 1 ton the Earth would blow up but then gravity would pull everything back onto itself.
The Earth would basically look like it did 4 billion years ago.
Now here is my question. Would history repeat itself? Would the Earth somehow heal, and literally be rebuilt by going through differentiation and so forth with an albeit different outcome concerning species (IF ANY), and landmass etc. Being in the just right area of the solar system would an atmosphere form again, oceans form much later through collisions?

Would it be possible for this to happen I wonder.

Yes with infinitely small probability.

Maybe instead of humans rampaging all over the earth, spreading AIDS and killing Mother Nature, it'll be some mutated vegetarian land piranhas.
On a serious note, yes, due to the 'right' distance of Earth from the Sun.

Just thought of several drawbacks that the Earth would be doomed and never finish it's "healing" cycle. The solar system was a lot different 4 billion years ago and maybe comets etc. That were around at that time are more scarce now that before thus no oceans etc.
Also:
Assuming that resources in the solar system are much more scarce I would assume that it would take longer than 4 billion years. Either way the Sun would be a lot different and maybe the Earth more so. The right area would be null and void if it took longer than 4-5 billion years.

For history to repeat itself, the Earth would have to collapse back into itself in the exact same arrangement it did way back when...so the probability is infinitesimally small.
Life very well may start up again, but it will most very likely be vastly different from how things have developed now.
In addition...the path that life took was heavily influenced by the five major mass die-outs. For instance, the era ruled by dinosaurs is speculated to have been brought on at least in large part by a large meteor striking the earth...things like that would also have to be taken into consideration.

most emo post ever.
but yeah i agree, the earth would rebuild itself, and reform, thus creating zerg.

They're lol-ing from Pluto

the only way I'll care is if I'm reincarnated, and at the rate I'm living my life i'll probably become a worm or a dung beetle, so i doubt it even then =(

Maybe we'll reincarnate as dragoons. Now THAT would be cool.

Would history repeat itself? Would the Earth somehow heal, and literally be rebuilt by going through differentiation and so forth with an albeit different outcome concerning species (IF ANY), and landmass etc. No. The amount of degassing and radioactive depletion we've had in our planet has substantially changed the chemical composition of our planet, and the outcomes it would have if it restarted today. We're also lacking in solar system conditions which would give rise to the carbonaceous chondrite bombardment, which means we would have far less water.
Also, stealth is 100% right that our sun would be in a different state than when we formed. The solar systems' 'water belt' has substantially moved, and its quite possible that without the action of a functioning magnetosphere (which we wouldn't have until accretion is nearly complete) that the increased heat from the sun would basically ionize and strip away any atmosphere we had left. Some additional atmosphere would be produced by de-gassing, but without water its far more likely that we pull a venus because of a lack of tectonic carbon regulation.

3 things are different in this Earth mark 2. Heat. The earth is cooling down for billions of years. Will the resulting heat be enough to power tectonic shifts and vulcanism like it did billions of years ago.
The moons used to be in a much lower orbit billions of years ago with stonger tidal pull on the geology, atmosphere and seas. The Earth has been bombarded by comets asteroids and spacedust more violently then it is now. Most of this material has been absorbed by the planets and the sun, catapulted out of the solar system or in orbit where it is very unlikely to hit anything.
The composition of earth mark 2 will be the same but the distribution of the elements might be very different. What the result of all this will be I don't know. Maybe a smaller Earth with 2 moons or a Saturnlike ring.
There was an Earth mark-0 proto-earth that got smashed by a small planet in excentric orbit. This shaped the earth and the moon. The excact geological footprint of earth has been found on the moon. The moon is comprised of mainly the impactobject. Earth mostly out of the Proto earth.

That's pretty much what I figured with much more scientific reasoning. Thanks. What happens when a sun supernovas? Does it destroy nearby planets and shit?

Yup. The supernova star expands in diameter and burns everything which is close. I have no idea what close means for a star but I guess it is billions of kilometers.

yes just like how my cellphone has a possibility of jumping off my desk... cept it's just really really really small
to ans OP not it's not possible
cus in taht short amount of time earth's center of gravity and gravitational pull would be fuked up and u r then disturbing a very delicate thing... so earth would essentially become like any other inhabitable planets (probably)

Does history have to repeat itself? Are we so special that we need to be recreated?
Another question is "Is repeating itself right now?" Under many theories, the Big Bang was just one in an infinite continuum of such events. Though the next one won't happen for billions of years, the question is are we unique and special in any sort of way? In that sense, like snowflakes, however ephemeral will are unique and if we were to be reconstituted we will not appear as the same individual ever again.
