The sun will eat up the earth in like a million years

The world can end 2day it can everyday you never know i think an mega astroide will ends the world in the future.

Ozy wrote In relation to life on Earth ending, I can see a natural disaster occurring on a monumental scale, much like the event that resulted in the almost complete extinction of the Dinosaurs.

In relation to the Earth itself being destroyed, a rogue planet impact could occur before the Sun expands in 5 Billion years, however, [If Euler would like to clear this up], I'm not sure whether that would result in the complete destruction of the planet, or simply the scorching of it.

Firstly I would just like to correct you in that, the process of the expansion of the Sun will actually begin in roughly 1.1 billion years, but is a hugely long process, and will last up to around a further 9 billion years after that.

However, the process of two planetary object colliding would, without a shadow of a doubt, completely sterilize all life on the planet. However as for destroying the planet itself would be completely dependant on the structure, mass, density etc, of this rogue planet. If this planet were massive, very dense, and moving with, relatively, high velocity then the Earth itself would be completely destroyed.

However in the case of another planet similar to that of Earth, in that it is of a similar size, mass etc, then in the process of this collision, the two planet's could possibly conjoin. There would be an unbelievable amount of destruction, huge amounts of each planet would be ejected into space, but it is possible that these two planets cold then form to become one. In this case however, yes the planet would be completely scorched, of course as a huge amount of heat would be generated in this process.

Hopefully that makes sense, it's quite hard to explain.

Probably an internet meme.
Thinks about it:3

Yellowstone Supervolcano...

jsl wrote since i have done astronomy, i think that our galaxy (The Milky Way) and the Andromeda Galaxy will collide and create a new galaxy, causing all types of life to be wiped from both galaxies if there was anymore out there but that would take millions and millions of years :}, but thats just me :p

I thought if two galaxies combined the end result would most likely be the formation of a black hole? Or am I mistaken?

More than likely a nuclear war. I hope zombies though, that would be awesome

I believe there will either be a nuclear warfare, or as jsl said The Milky Way and the Andromeda Galaxy will collide. Another possibility is that the sun will die out, but if that's the case it's not really possible. The Milky Way and the Andromeda Galaxy will collide sooner than it will take the sun to die out. The sun still has x billion years.

I'm pretty sure its gonna end by nuclear war, not necessarily because of the explosions but radiation damage which causes baby's to become dis formed + it can cause you to develop cancer

most probably a nuclear strike!
it wouldn't be done by nature, it would be done by humanity!
