I Know Its Kinda A Random Question. But It's Been Buging Me So I Had To Ask It.Haha. If Anyone Also Has Any Guesses To How Long It Will Be Until The Earth Ends Of Explodes Or As A Global Flood Or Anything, I Also Would Like To Know That Too!:)

No. Havent even sent a robot. If we did it would take a long time to get there. By travelling at half the speed of light (not yet possible) it would take 140,000 years to get there. There being the Sagittarius Dwarf Galaxy, the closest known galaxy to Earth. So since we just made our exploration to space last century... we havent quite made it that far.
As to your last question about the end of the world... just dont listen to anybody and decide for yourself. Hopefully you wont ever find the answer.

No.
The nearest galaxy, the Canis Major Dwarf Galaxy, is 25,000 light years away. That means a beam of light would take 25,000 years to get there.
Light travels at 671,000,000 miles per hour.
Canis Major is 147,000,000,000,000,000 miles away.
We haven't really sent people much further than the moon, which is only 239,000 miles away.
The furthest thing we've ever sent out, the Voyager 1 probe, is only about 9,300,000,000 miles away. And it's taken nearly 30 years to get there.
If it kept up its current speed forever, it would take over 474,000,000 years to reach Canis Major.
Even the nearest star to us, Proxima Centauri, is 24,800,000,000,000 miles away. It'd take Voyager over 80,000 years to get there.
The Helios spacecraft, the fastest man-made vehicle ever, traveled at about 150,000 miles per hour. That's about 5 times faster than Voyager, but it'd still take about 16,000 years to get to Proxima Centauri and 94,000,000 years to get to Canis Major
Anyway. The sun won't go nova (expand to such a big size that it swallows Earth) for another 5,000,000,000 years. In the unlikely event that humanity is still around then, I'm sure we would have developed faster-than-light travel.
I hate thinking about numbers this big, it just baffles me. That's why I wrote out all the numbers in a long form -- to illustrate how huge they were.

well the mayan calendar ends in 2012 the world might end then. global warming might end life in another couple decades, an asteroid is due to hit earth in 2069, too
