When do you think the world will end?

Question

Any beliefs please

Answer 1

It will be engulfed in flames when the sun finishes its hydrogen fuel and starts fusing helium, thus turning into a red giant with a radius that will extend beyond the orbit of mars.

Answer 2

There is a photo at galaxyleap.com that shows an example of what our solar system will roughly resemble when the sun becomes a dwarf star. It's near the bottom of the first page titled "baby nebula" . I really forget the name but you will see it. You have no worries though as to the end of the earth. It will take place in approximately...ya ready?...goggles on? helmet on?..5 billion years.
As we live the earth, now 93 million miles from the sun, edges closer to the sun and the galaxy Andromeda. The sun will run out of nuclear fuel and, as I'm sure you have heard the word, go super nova. At it's brightest it will then fall in on itself becoming what is called a dwarf star. Earth will either be burned and broken to pieces to soar the universe or will link up with the Andromeda galaxy becoming an interactive galaxy. Either way...No worries.

Answer 3

The common answer, as some have already noted, is in four or five billion years. An earlier catastrophe could occur, as one person mentioned. But it is now believed that our galaxy will collide with the Andromeda galaxy in only a couple hundred million years. This could cause extreme disruption to the solar system. Little planets like ours could be ripped away from the sun and thrown into intergalactic space. It would become an ice world long before it left the galaxy, though. Or a star could come close enough to cause a collision.

Answer 4

About 5 billion years from now.

The sun will have used up too much of its hydrogen to maintain its energy output.

Gravity will cause it to collapse, until the next level kicks in; it will then expand to nearly Jupiter's orbit, becoming a red giant star.

Things won't be good on Earth during that time.

(Sorry I'm a bit fuzzy on the details. It's been a few decades since I took astronomy.)

Answer 5

What does that mean, "the world will end"?

Religion thinks the 'world will end' when their god comes in and kills all the people they don't like.

Science says that the 'world will end' when our star, the Sun, explodes or another star close enough to blast us out of the sky explodes.

The Sun is not likely to explode anytime soon, but another celestial body close by could explode at any time.

So my answer is "I don't know."

Answer 6

In several billion years when our sun runs out of fuel for its nuclear furnace and turns into a red giant, and then the Earth gets burnt to a cinder. (A certainty)

However, the end could come sooner if a large asteroid or comet hits our planet and wipes out all life. (Possible, but unlikely)

And then of course there's the possibility of nuclear devastation, but at least *some* life would survive this...

Answer 7

The earth will be impacted by a large body from space or it will be burned to a crisp within the expanded sun as the sun is in in its final stages as a star.

Answer 8

21 December 2012 fills the 13th and final baktun of the Maya Long Count Calendar - end of time. Take Christmas early that year for Betelgeus is going supernova.

2015 - US Social Security and Medicare implode with Baby Boomer retirement, and the entire Welfare State with them. Riots, burning cities, end of toilet paper shipments to stores.

2050 - end of petroleum, end of petrochemistry. All First World civilization collapses.

Answer 9

Next August. The 12th, I believe. Get ready.

Answer 10

Why of course...
