Top 10 Things/Questions About the Universe That Scare Us

Space is a beauty of a devil. It's vast and quantitative, yet the quantities of horrors that lurk in it insert terror into our hearts and minds.

With the more so recent theory of 'Planet X', which says that every 27 million years it dislodges comets and asteroids from the Kuiper Belt, which essentially causes mass extinction if they strike Earth; if it's real, it would lead to mass extinction of all species on Earth this month.

It's scary to wonder what space brings us. We all know that black holes exist, we don't know where; we know Earth will be destroyed, we don't know when.

So here you go.

The Top Ten

Black Holes

These are a region of space having a gravitational field so intense that no matter or radiation can escape. Yes, not even light, the fastest particle in the universe, can escape a black hole. That's scary, considering that the average human runs at about 8.3 miles per hour. Guess 'The Simpsons' were inaccurate.

When you are sucked into a black hole, you are stretched, since one end of your body is closer to the black hole than the other half of the body. This is called 'spaghettification'. Your body would be stretched, and I would imagine that you would be stretched many miles.

Not a good way to go out.

According to science, you can use a black hole to access any of the 10 different types of dimensions. Or if something goes seriously wrong, you could be in five dimensions at once, perhaps, and you would be changing the past and the future at the same time. There would be no present; you'd just be stuck in this void-like dimension.

There was this one planet between two black holes with these weird creatures that had a messed up philosophy of the Force-too much?

A pit of nothing in the middle of no where, sucking up infinity. Talk to eternity about this one.

Its theorized ends

Then maybe you could thing of it as infinity putty, or something, and you just keep stretching it out and out. Its harder to think of putty as stretching INTO anything: it just is stretching. I don't see why metaphor and analogy can't be interchangeable here, especially since I'm not really making an arguemnt, but if so, my mistake.

You're right that there's no way of proving this when we can't see anything outside of the universe, so I agree, but we DO know that the universe is expanding, and if we don't know if there IS anything for the universe to expand INTO, then I think its very logical to assume that its simply expanding not into anything. Nothing in the universe makes any sense to humans at this scale, so maybe don't get so heated about it.

I told you to ask an astronaut because they're people who have gotten legit degrees and aren't 14-year old internet people. I suppose anyone who has extensive knowledge on physics and astronomy work though, 'cause astronauts ...more

@visitor
The universe isn't expanding into anything. The universe encompasses everything, and so this "non-space" of yours can't exist because its part of the universe. It's like the universe is a big, edgeless (dude! No edge! ) balloon that includes everything. There's nothing around it, no air, no space and if there was anything it would be inside of the balloon because the balloon has everything. It helps to think of everything on the surface of the ballon, because that shows how everything is rushing away from each other and not shooting out from a central point. And its just expanding. A blown-up glove also works for this metaphor, that's how my science teacher put it.

I probably can't explain it. Ask an astronaut.

There's this one theory that says that the universe will stop expanding at one point and will start contracting.
Oh, there's this other one that says that the universe will heat itself up until it can no longer sustain life.

This is some creepy stuff.

To clarify, I never said I was an expert on science. Or space. I found theories on how the universe will end and tried to explain them the best I could.

Give me a break.

Did you ever stop and seriously question into WHERE the universe is theoretically expanding?

Asteroids

Comets, meteors, whatever you want to call them, are bits of rock in space. Big bits. They frequently hit planets and sometimes leave a big impact. They are hypothesized to be what had killed the dinosaurs.

If one hit Earth today that was big enough, most likely all of humanity would be dead. - SwagFlicks

None of the items on this list are really that scary. I'd say "fascinating" is a better way to put it. - RockFashionista

I would say almost all of them, since black holes are absolutely terrifying. - SwagFlicks

Regarding Wonkeydude's comment, I can see your point. Not many asteroids have hit Earth. The one's that are big, however, and have hit Earth, are absolutely terrifying. Imagine one of that size hitting Earth today. - SwagFlicks

These rocks are six miles long(I wonder what Kitersunu will say about this) - Nateawesomeness

Its vast space

Space, for the most part, is large and constantly expanding. We are one spot on one spot in it. Think about that.

It's scary and kind of depressing to think that you and I are spots on spots, or irrelevant. Irrelevant in the constant expansion of the universe.

Aliens

I used to watch Ancient Aliens on History Channel CONSTANTLY with my mom when I was a wee li'l chilli pepper, and now I'm paranoid about them. - Miauzer

Considering the size of the universe, it's almost certain that extraterrestrial beings
exist somewhere in it. Whether or not they are hostile or passive, their arrival on Earth would probably scare us really badly. - SwagFlicks

We have no idea what they will do to us,will they make us their slaves,will they torture us with the most painful of methods,will they rot all life on earth with diseases? nobody knows - Nateawesomeness

Is Earth the only planet with life?

If not, what type of life is on other planets? If yes, then its certain that we are doomed to be alone in the universe. Forever.

The concept of it repeating itself in another Big Bang

A theory says that the universe won't end, but will be recreated in an way similar to the first Big Bang, which was when a dense packet of heat began to expand.

It's scary to think about because well, we don't know if our being would exist in the universe or not. We might exist, but we might not be ourselves. - SwagFlicks

Can any other planet sustain human life?

We can probably adapt to survive every planet. - IronSabbathPriest

It's a 'maybe' answer, as we know other planets have the possibility of sustaining human life via their resources, it's just the question of if we can reach those planets in time. - SwagFlicks

What will happen to the universe before it ends?

Before the universe will end life will end. It's a proven fact that our sun will die which will end life on our planet.

I mean, we don't know what will happen, just like we don't know what will happen in the next second. And the second after that. And the second after that. Basically, multiply the mystery of the next second by... a lot. - SwagFlicks

Being alone in it

It's scary to think that if you are sent into space, alone, you would just float around until you die. Its vast emptiness makes you feel insignificant, referred to above on my #4 choice. - SwagFlicks

Just grow potatoes - idontknow

The Contenders

Parallel Universes

Parallel Universes are not Real

Enough said. this should be the scariest.

What happens when we encounter an alien species?
Supernova

These are beautiful, but also deadly at the same time. - SwagFlicks

Our Sun will diffuse one day and what happens if we fail to find another planet to live upon?
Planet-wide Extinction
White Holes
