Will the world stop revolving?

The rotation of the earth is slowing down at about 0.7 sec per year and this rate varies. So it is not going to stop any time soon.

This question is so very childish and without foundation. Who ever gave you the information that the world was going to stop revolving? This is pure CRAP.
And, check out the websites for more accuracy, please. The rate of "braking for the Earth's rotation is more like a few MILLIONTHS of a second per year, not seven tenths of a second per year. At that rate we'd be losing a day every 5000 years. Scientists have already calculated thatr the "braking" effect of the Moon on ocean tides has caused the Earth to slow down from 425 days a year about 370 million years ago to the 365 days/year we have now. That's an average loss of a day every 6 million years, not 5000.
People, get with the science. Don't mislead.

The tidal friction caused by the Moon is slowing down Earth's rotation by a tiny amount. If it were to continue that way, it would take billions of years for the Earth to be in "lock-spin" with the Moon (Earth always turning the same face to the Moon, the same way that the Moon is already always turning the same face towards Earth).
The tidal friction from the Sun is also contibuting (much to a lesser extent). However, it would vace to disrupt the Earth-Moon lock spin before it could then stop Earth's spin: we would then always turn the same face towards the sun.
However, this would take so much time that, in the meantime, two things will have happened:
1. The Sun will have bloated out to its red giant phase and, maybe, eliminate Earth in the process. This is approx. 5 billion years from now.
2. The Andromeda Galaxy and our own will collide. Although stars will miss each other (lots of room between stars, even in the dense portions of a galaxy), the gravitational ripples may separate some planets from their stars. Will we be one of them (that is, if we survived number 1). This is 6 billion years from now.

The world is slowing, but it will never stop. The moon is causing Earth's spin to slow, and likewise, the energy that's being robbed is added to the lunar orbit - so the moon is slowly moving away.
If the Earth & moon are around long enough (before the Sun exhausts all it's fuel), then eventually, the same side of the Earth will *always* face the same side of the moon, and our "day" will be the same as the lunar orbital period. (I've heard an estimate that this will be about 32 to 35 days, if Earth lasts long enough for it to happen.)

The world is not going to end and no it is not going to stop revolving. People have predicted through time that the world would end on this day or that day but that day has came and gone and we are still here. It's not going to happen no time soon.

It will end this revolution at approximately 12am Greenwich time. it will then immediately being it's next one.
Yes, it will stop revolving in about 3 billion years when it gets sucked into our "red giant" sun.

Earth ends its revolution slowly like 0.5 sec per year. it stops only after 3million years. so don't worry dear.. we will develop lot of new technologies and human beings spread over this galaxy and so far..
