What is the scariest scientific concept?

[TheStatutoryApe]

The "atoms" your were seeing were insect scat?

What? Floating around above your bed??

Actually, the "atoms" were my retinal rods firing from photons in the near-dark, the one that chased me during my early years might be described as a very threatening "black hole" (or was derived from a stay in a cabin with scary knotholes) and the eventual change of its image into insect scat (while dreaming, now under control in my hand, yuck, but just that of an insect) made it more ridiculous than dangerous.

Its funny that this happened to me too. I used to see "static" like on a television (gives you an idea of my generation there) in front of my eyes at night when I was trying to sleep. "They" would not go away and I determined one night in my mind that these "static" entities (I watched too much star trek the next generation probably) were really my friends and not weird oppressive beings that would not leave me alone. I later read that these 'dots' and such are apparently bacteria and other micro organisms floating on the lens of the eye.

Its good to know that I am not a total freak, except perhaps for 'making friends' with the bacteria and microorganisms in my eyes.

Thanks for all the comments :-)
I am quite surprised there were not more about time and also maybe other things like particle duality (or more generally the quantum world) or the vastness of space or, or, or...

haha, i see the static too, but also during light. I must have a lot!

Very interesting, so it can be a type of "migraine". I have had two opthalmic migraines that have the cool glowing crescent filled with undulating geometric designs. I wish I could have another, it was the most amazing thing.

Yes, some results from experimental psychology on "human nature". For example Milgram's "torture experiment" or one of its variations, or perhaps the more famous (albeit perhaps scientifically less sound) Stanford prison experiment.

Isn't the holocaust a direct evidence of such a dark nature of humans.? Not just the holocaust, there were several million wars before the WWII and in each of them not just the soldiers but almost equal number of innocent civilians were also murdered and raped. All these rapes and murders were committed by the apparently normal human beings who were ploughing the fields or making jewels before a particular war started.
I think the whole process involves many steps. Maybe initially they had moral issues. Then due to helplessness and the power of the higher authority-as they perceive it-, they give in. Then the second theory of milgram comes into picture. "He says; I do; Who cares" approach.
Then i think a third step is involved.. Which i think Milgram missed. (I just now read the article on his experiment in wiki though i have thought about this nature of humans before) With prolonged obedient working, humans begin to get joy from the work. Like institutionalism in jails (remember Morgan freeman of the Shawshank Redemption). Killing and massacring seems enjoyable.
I am afraid.

are there any scientific concepts/topics that freak you out?

Cloning, Earth's fragility, and my own sentience.

Only a few truly scared me(and still do, when i think about them); of the few:

That we may all be irrelevant in the universe. We have such egos that makes us believe that we do matter and make a difference, but what if we don't. We are not even in the center of the milky way.

Earth, our universe, is a study/ research and we are small particles being watched on by aliens in white coat. Think of Dr Suess's Nortan Hears a Who. I was surprised he had the same idea i did.

In few billion years the sun will expand and destroy the earth...When I learned about that in the 1st grade that scared me

GRBs. I don't like threats for which there is no possible defense.

Spaghettification - what a way to go!

Global Climate Change - perhaps the greatest challenge ever faced by civilization.

Those would be the sorts of things that motivated me to get a physics degree. "Scary" is not the word that comes to mind.

that one got me for a while too, back in the 90's actually when I first got interested in physics

Looks like it's just me that has issues with the size of space or duration of 'time'...

As a side note, are you going to have a 'Happy 10,000 Posts' party?

It always seems weird to me when I hear people say things like "cosmology freaks me out" or "I don't like to think about those things". To me, the scarier thing would be if humans only had the capacity to think about proximate trivial things. It would be such a loss.

A note on the dying thing, while a priori non-existence seems like the most likely outcome, it doesn't seem that likely to me from a philosophical perspective. Think of the anthropic principle. We can't perceive non-existence. If there is any outcome to the universe besides a single universe that "ends" (without the possibility for the creation of a new universe) then it would seem eventually "we" would reform at some point. And the single ending universe scenario seems unlikely, since the universe did form from "nothing."


Also, I find the concept of torque scary.

if the ozone layer will be broke and the Earth will be hit by the sun, and we all be burn from that heat coming from the sun...
this really scares me.. so now, we still have time to preserve and save our mother earth.. let's all be aware of this..!

Reverse Universe.

Among the physical laws it is a general characteristic that there is reversibility in time; that is, should the whole universe trace back the various positions that bodies in it have passed through in a given interval of time, but in the reverse order to that in which these positions actually occurred, then the universe, in this imaginary case, would still obey the same laws.

Imagine it; complete craziness. The universe would begin to shrink, resulting in the reversal of time; the reversal of ENTROPY. This is incredible, but quite hard to swallow.

Don't worry though, this will probably happen in more than a trillion years.

The fact that everything I ever know or could ever know will amount not not more than 1 part in trillions and trillions in both the time and space dimensions. That so much of this vast universe is censored from us.

Reminds me of when I was 3-5 years old and noticed "faces" in wood paneling. It always felt like someone was watching me in those rooms.

What's scary? The idea that maybe we're all hardwired with this type of behavior as a solution to the "too many people, not enough resources" problem.
