Supernova
Violent explosion of a star. The star is destroyed, with a remnant forming a neutron star (pulsar) or black hole (collapsar) depending on the residual mass. There are generally two forms of supernova. One results at the end of the life of a star with at least about eight solar masses, which in a series of progressively shorter-lived and less efficient thermonuclear reactions generates ever heavier chemical elements in layers about the core. Effectively this is a star that lives fast and dies young. When each step in the process chokes up the core with nuclear "ash", contractions follow under gravity, driving up temperatures until they are sufficient to synthesise the next heavy element from this waste product. When the core fills with iron, the end point is reached; it takes more energy to fuse iron into anything heavier than the fusion reaction produces. At this point the star collapses, driving temperatures into perhaps twelve figures Kelvin and triggering an explosion that blows most of the star to smithereens. A second type occurs in close orbiting binary systems where one star A, being more massive, evolves more quickly to the red giant phase and develops a thin outer envelope and a core rich in carbon. Its companion B skims off the outer layer, grows in mass and itself evolves to the red giant stage. At this point the carbon-rich star A begins reclaiming the hydrogen; when the gas accreting onto it drives its mass over 1.4 solar masses a huge nuclear reaction ensues and A blows itself apart. Supernova explosions can briefly outshine the combined output of all the stars in at least a modest galaxy. They are also responsible for seeding the Universe with the heavy chemical elements of which the Earth and our very bodies are made.
The Urban Dictionary Mug
ABSOLUTELY LOVED IT BUY IT RN
Was very happy with the customer service team when I had a question. They responded to my email quickly. The mug looks really cool, makes me laugh every time I use it and high quality. I’m in love with it. Thanks!
Haylee My name is haylee sullivan and the mug is describes everything about me and i would rate it at a 5 100% it is awesome
I’m right handed and would’ve liked it better if the handle was on right side with name facing forward instead of having verbiage facing front
girlfriend loved it :) - Ian's Girlfriend
the urge to buy it and write cum on it
Purchased this mug as a Christmas gift. Can’t wait to see the reaction!
This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
These are hilarious! Great gifts. Cost seems a bit high but i couldn’t resist.
It’s a great way to store my pencils.
I used this instead of condoms It didn’t work and now my nephew is my son
Ordering was very easy and the delivery to a different address then the billing address was done effortlessly with complete correct order. Was delivered before estimated date which was very exciting. Good job well done by all.
Funny stuff! I wish the mugs cost a bit less, I'd buy more. There's an almost unlimited supply of clever slang.
awesome. came just as ordered.
Nice cup a few words were darker than the rest. But ok
아주 좋은 머그잔 나는 죽은 아버지를 위해 시원한 머그잔을 얻었고 매우 자랑스러워했습니다.
I like the mug, it’s good quality, unfortunately the customization wasn’t correct. I got the “juff” mug and instead of the definition i had a quote from one of my friends as a bit, but it just came with the definition. I’ll still give it to him because the joke still works but I am a little disappointed.
Love the fact that Urban dictionary came up with such an accurate and quick meaning for Binger! Mug was a little pricy but God is my morning coffee so much better in this mug!!
This mug is incredible! It was a great gift for my friend named Jacob, who is definitely gay. (Even though he says he isn't 🙄)
Great mug, she loved it
