Nuclear warfare is on many people's minds these days as the ongoing war between Russia and Ukraine continues to develop. Tensions on the world stage have been higher than ever and plenty of analysts have posited that we're all experiencing a throwback to what it was like to live during the Cold War era.

Of course, none of us want to deal with the possibility of a nuclear strike because the use of even one bomb could trigger widespread nuclear warfare. There's a reason why the principle of mutually assured destruction (MAD) has successfully kept the possibility of nuclear war in check.

That said, it's always worth learning more about any topics–including nuclear weapons.

People shared their knowledge with us after Redditor glasas007 asked the online community,

"What is a weird fact you know about nuclear bombs?"


"54% of the US's deterrent nuclear weapons are on board nuclear powered submarines capable of prowling the ocean for 70 days at a time, their exact locations known only to their crews. Their mission is to remain hidden so as to assure second strike retaliatory capability."


And they are typically commissioned with enough uranium to power them for 20 to 30 years. They can be resupplied at sea for various crew requirements if really necessary.

"Don't use conditioner..."

"Don’t use conditioner in your hair in the wake of nuclear particles. It’ll bind the radioactive material to the hair shaft."


So you're telling me I have to face the aftermath of a nuclear detonation AND have dry hair?!

"Before the first one..."

"Before the first one was detonated, there was some concern that runaway nuclear fission reactions would continue as a result of the bomb, until the Earth's atmosphere was destroyed completely. This was found to be 'unlikely' before the first bomb was tested."


So what you're telling me is that they just said, "F*ck it, just try it."

"The Castle Bravo test..."

"The Castle Bravo test ended up being WAY bigger than the scientists predicted. The video is on youtube and it's crazy."


It also wrecked a lot of equipment and buildings it wasn’t supposed to! Its fallout heavily irradiated a Japanese fishing vessel, which was quite "uncomfortable" in a diplomatic sense.

"There's a website..."

"There's a website where you can superimpose a nuclear blast over various cities. Helps give perspective on the scale of the blast."


Really puts it in perspective when you see the size of one on your hometown!

"During the Cold War, for the U.S. alone, 32 nuclear weapons were lost due to accidents, six of which were never recovered."


Nice to know they're just chilling out somewhere. So reassuring.

"That thermonuclear devices..."

"That thermonuclear devices consist of a primary fission in the 5kt range that starts fusion in the secondary by means of focusing the xray burst into heating the secondary material. The shape of the xray lens is classified and if you were a physics student and you wrote a paper describing how to do it, it instantly became classified as well."


Damn, imagine spending so much time figuring out how to make it only for the government to classify it!

"Depending on how high..."

"Depending on how high the fallout is it can be blown around the Earth by winds affecting everybody."


Freaky, huh? Again, sooo reassuring.

"Fun fact..."

"Fun fact: if one can intercept a nuclear missile the odds of a nuclear explosion is extremely low."


Unfortunately, the odds of successful interception are also rather low.

"Once the chain reaction..."

"Once the chain reaction with the uranium is initiated, neutrons bounce around inside the device triggering more atoms to release their energy. Early designs exploded before much of the nuclear material had even been triggered, leading to wasted uranium and smaller explosions."

"The most effective designs contain this chain reaction for as long as possible like a pressure cooker to maximize the size of the explosion."


Another fun fact: They used beryllium around the nuclear material to reflect the neutrons back into the material. It was called a tamper.

Hopefully you've come away from this a little more knowledgable about nuclear weapons, and it's worth checking out more authoritative sources!

Kids start going to school from the age of five, and for the most part, they spend more time at school than at home. Because of that, teachers can become very important figures in the lives of their students.

Some students don't have the best home lives. Some keep it to themselves, but others confide in their teachers.

Curious about various situations, Redditor Delicious_Mastodon83 asked:

People Divulge What Depression Really Feels Like To Them

TRIGGER WARNING: This article contains sensitive content about depression and mental health.

As the stigma around mental health lessens (however slowly), people are more forthcoming about the problems they are facing. One of the most common mental health issues is depression.

Depression can affect many different types of people. Factors such as gender, race, nationality, and even age have no bearing on whether someone suffers from depression or not.

According to the World Health Organization (WHO), globally, " estimated 3.8% of the population affected, including 5.0% among adults and 5.7% among adults older than 60 years..."

Depression displays in certain patterns, such as mood changes, physical difficulties, and social isolation. However, depression manifests differently in different people and feels different to different people.

Reddit users divulged what depression felt like to them when Redditor iodineseaspray asked:

"What does depression feel like to you?"

Some of this is sure to sound familiar.
