Great thoughts, I haven't really thought in this direction before. But it's actually possible for us to communicate with other planets just like we travel across other nations and continents. 

But then, science still has a long way to go.  And again, some of those planets cannot sustain human lives. Those are some important considerations. 

All things being equal, if live is possible in other planets, some people will willingly pack out of the earth to start a new life in Mars or Jupiter 😅

It only takes research to know what other planets got that we don't really know on Earth.

> Right now to understand if Mars has water or not, takes a lot of effort and money but at the same time, we have not had any breakthrough yet.

Oh, we definitely know Mars has water. Maybe you mean _liquid_ water.

>  If all the diamond reserved in the world is depleted, we can possibly travel to other planets to mine resources from there.

Yes, we could also mine comets and asteroids. Have you watched _Don't look up_?

> I also had a doubt if there will be a difference in weight our earth when other planetary objects come here or if we take objects to other planets. 

Of course there will, hehe. Check out some amusing YouTube videos where they simulate driving a car under the gravity of the moon, Jupiter, the sun and so on.

> There is also another possibility where we might have a huge nuclear war and we end up starting everything from scratch with a bow and arrow.

I agree. We might become extinct before we get to colonize other planets :S

Interesting insights.

If we don't throw e-vaat, the earth will throw us in some other planet

Nice immagination bala g

If earth becomes very polluted ,the point may be vital Hehe.

Well said . I also believe There will be a time when the resources on earth will be so limited and the only way forward is to go get them from other planet, how will human survive then🤔 ?Wonderful article .

I think space explorations or travelling to other planets will be possible in a few decades time probably the next half of this century. Also, What we term 'waste' here might not be labeled or seen as waste on those planets. If it's inhabited then we can also do trading with them lol, like mining in exchange for 'waste transference'.
