There are comets, the sun light dying out, black holes? what is the risk of these coming? how long will it take? Would it scare everybody?
I would be scared I get worried about it because who knows when this could happen I would hope it wouldn't happen while i'm alive.

Comets have been around since the formation of the solar system 4.5 billion years ago. While they can pose a very small threat to Earth, there are none (that we know of) on a collision course with us.
The sun won't die or burn out for another 4 billion years or so, so I'm not worried about that. And the sun won't become a black hole (its not massive enough).
And the closest black hole is 25,000 light years away in the centre of the galaxy (as far as we know) and its not headed our way and we aren't headed in that direction.
So all in all, I'm not worried about anything from space. I'm more concerned with things right here on Earth - wars, global warming, etc.
Those are the real threats to individuals, not objects from space.

There is very, VERY little chance of any of those happening during your life. Comets do occur and they do hit the earth, but very seldom. As for sun light dying out, it isn't. The sun should carry on just like it is for another 4 billion years or so. And there is almost no chance of a black hole eating us up.
The greatest threats to our continued survival are things we cause, ourselves, right here on earth.

Eta Carinae is a large binary star. It is VERY close to exploding into a supernova. Of course, because of the distance, it's allready exploded about 8,000 years ago, so when the radiation gets here we will have seen it explode slightly before. If you live in the southern hemisphere, you will be showered with radiation, luckily, most are neutrinos.
All this will happen in roughly 5 - 15 years. The effects could be disastrous or they could be mild, like a tiny rise in UV rays.

The sun won't dye out, as it is in the main-sequence section of an H-R diagram and should live for another 4 billion years, and the chances of a comet hitting earth (let alone killing YOU) are as small as can be.you have nothing to worry about.we are not in a very active part of our solar system either, so that decreases our chances of getting hit with anything bigger than us.

There are a lot of very scary and horrific things going on out there in deep space and it worries a lot of us all the time.
Some of us spend our nights just trembling in our beds wondering when it will all come to a final blazing end with clouds of ash and balls of fire shooting out all over the place. We see movies of giant flood waves washing over cities all the time on television and hear stories of huge asteroids falling from the sky at thousands of miles per hour which crash into the earth with devestating force. And people talk about the endless nights which will occur if something like that happens. It scares me to death.
To offset this fear i have taken to a secret plan which I recommend to you and any of your friends who might also be scared. Find a good metal box and hide it in your room. Into that box you want to hide bottles of water and as many candy bars as possible to help you get through times of food and water shortage that are sure to come about when the world comes to an end. It is always better to be prepared than to be caught unaware by a terrible disaster.

The most thing you have to worry about before any of these you posted, is extremist people on the planet...( Inner atmosphere Nut's that haven't' fallen to far from the tree...Environmental oxygen Hogs using up our inner atmosphere without ( any ) conservation...The things above you have mentioned will happen after we are gone..

I don't find anything scary about space. It's all part of the natural world. I find that when I truly understand what's going on, I'm overwhelmed by the majesty and beauty of the universe, and find that there's really nothing to be afraid of.

great black holes are incredibly uncommon at the beginning, and it rather is even rarer for an merchandise to bypass throughout the form horizon (the element of no return, in an attempt to talk). they're not something in any respect like the cosmic vacuum cleaners that they are made out to be. think of of it like this: If the sunlight develop into replaced good now with a black hollow of a similar mass, earth might nonetheless save on in incredibly lots a similar orbit. it rather is only as quickly as you bypass the form horizon that gravity will become intense. in my view, i think of great novas are slightly scarier. If a close-by famous guy or woman is going great nova and one among its poles occurs to be directed in direction of earth, we'd be blasted by utilising all varieties of radiation, which consists of a huge quantity of gamma rays. not precisely a delightful state of affairs... Doug: Hah, i develop into initially going to respond to with "existence", yet I figured somebody might beat me to it. good teach.
