I know Iron it the hottest element to make, but why cant the tempature in stars go on forever
they need to be hot enough but if it is possible under the right conditions and its probably out there we just haven't discovered it yet
The stars run out of atoms to fuse. Since there is so little fuel left (relative to hydrogen or helium) the star can't continue to fuse the atoms.
Why do supernova's create all the rest of the elements?
Supernovas create other elements because of the extreme heat. Protons then fuse together creating new elements
Because the of the extreme heat, supernovas are able to create new elements when the protons in the supernova fuse together. The supernova acts as a "element factory" in this way.
How hot does it have to be for the last element on the periodic table to be created?
The last element on the periodic table of naturally occurring elements is Uranium was formed in supernovas and the temperature that was needed to create it was 100 billion kelvin
Where do the elements go after a supernova
Great question Max! elements after supernovas spread into the universe and become bonded or brought together by gravity and made in to new elements
A supernova remnant is simply what is left over (i.e. the remnant) of a supernova. That probably isn't a very helpful definition, so I'll try to explain what I mean. First, I should probably define what is meant by the term "supernova." A supernova is simply the explosion of a star.
After the supernova, the elements spread throughout the universe and gravity brings the particles together to form new chemical elements
Stars live out their lives by burning (via nuclear fusion reactions) light elements like hydrogen into heavier elements like helium in their core. so basically the elements don't go anywhere they burn out.
I dont understand how hydrogen and helium were formed in the beginning and not some other elements, because the superforce was extremely hot right?
it was because they were lightest elements, and they had the least amount of protons and neutrons, so it took the least amount of heat to make these elements.
Hydrogen and Helium need less heat than other elements to be created.
great question : i think your answer is correct the big bang creates the plasma stage where matter cannot form atoms because of the extrreme heat, when this cools we have hydrogen and helium
How many elements did supernova's create?
Supernovas create every chemical element
Stars create new elements by squeezing elements together in a process called nuclear fusion. Stars can only create elements up to iron. Supernovas can create all the elements up to uranium.
supernova's create all the elements that weren't previously created in the stage where the star continues to heat up.
Supernovas create every element, but there are theories that very heavy elements are made when two neutron stars collide
I still don't understand how the elements are created through stars. I also want to know how this relates back to protons coming together?
How can you find out how hot the temperature needs to be for each chemical element to form? Is there a formula used?
In video he talked about small stars and how little their death is, how small are these stars?
Great Question, Cody, the above website explains how many of the smaller stars we cant see or cant get close enough to estimate their size, nearest smallest star is about the size of Jupiter,it would fit in Jupiter. So it has less fuel to burn and cannot react as violently as other stars when it tries to burn off helium and other elements.
What is the hottest temperature that a supernova can reach? Is there a maximum? Is there a highest temperature for the last element to be formed?
The hottest star we have found is called R136a1: hottest star and has a temperature of around 72000 degrees Farenheit but the supernova explosions may be over 100,000,000,000 degrees
Were any other elements created after a supernova?
Supernovas create all elements in the universe.
What is the temperature needed for Uranium to be created in a supernova?
This website should answer most of your question, does not have the exact temperature though.
How hot can a supernova get?
A supernova can get temperatures up to 6000 times that of the sun.
How can the Star's go so high on a Supernova?
I'm going to assume your question is, "How can the Star's temperature go so high on a Supernova?" And here is the answer. When a star reaches the end of its life span, it begins to run out of hydrogen to burn, so it begins to burn helium, forming carbon, then burning carbon to form the next densest element ect, ect. So the star becomes more and more dense in the middle, as more and more dense elements are created. And when a star goes supernova, the gravitational energy in the middle of the star, pulls all the other bits of mass closer to it. Therefore the star goes in on itself, pulling everything closer together, making it possible to create denser elements, because everything is so clumped up together, or dense. So since every part of the star is inside one little dot, and temperature is basically how fast the particles are moving in a space. Then the little clumped up star's particles are moving super de duper fast because they are clumped in a little space; meaning the temperature will be extremely high.
I still don't get how does a star uses elements like Neon, Silicon, and oxygen as fuel? How does it use elements not normally used as fuel?
Stars use Neon, Silicon, and Oxygen as fuel because it is not in the element form but still in the atom form. So this lets the star continue to fuse the atoms together to form larger elements. That's why most elements have the same number of neutrons and protons unless its a different isotope of that element.
Why does the explosions of stars create elements
Because the intense heat allows atoms to come together
Where is the nearest black hole and how far can they reach?
Answering how close the nearest black hole is is tricky as it is subject to change as technology for detecting black holes improves. At first scientists believed that the nearest black hole to Earth was the one at the center of the Milky Way Galaxy. This seemed to be debunked by the discovery of a new black hole only 1600 light years away. However, new evidence proves that it is fifteen times further away than anticipated. This just shows how in exact a science finding black holes still is.
Why is the 2 percent so important in the main sequence besides the creation of us?
It is so important because without that 2%, we wouldn't be alive.
is it possible to create a 500 proton element in a huge supernova?
can stars get any hotter then 3 billion degrees?
This website will answer your question but it says that the inside of a star can reach a tempeture of 10 billion degrees so yes they can get hotter than 3 billion degrees.
Why can't tempatures keep on rising in a stars core?
Because the star is not big enough to produce enough energy from gravity.
In the case of a black hole how do they stop?
I dont think they can stop.
Why does supernovas matter to Big History
Supernovas matter to Big History because they created all the known elements in the Universe.
Without them we would not be alive because they make all elements and elements make us
Why is the temperature of a dying star so much higher than during the star´s normal lifetime? (I didn´t get this one!)
In typical cases the larger the star the hotter the star is. As the star expands when dieing it becomes much hotter. Thats how it s able to burn elements a thgigher temperatures becuase of the expansion of the star. http://map.gsfc.nasa.gov/universe/rel_stars.html
Its like relating it to us the older we get the weaker we get this is like a dying star the older it is the less heat it will have.
What happens to these elements after they are made, could they possibly get destroyed? Do they just float outwards and do "elementey" stuff.
Atoms could change through alpha or beta decay, or through artifical means, so there's a chance some atoms could be destroyed.
Why is iron the most dense element able to be created by a star? Why aren't there stars that reach temperatures higher than 4 billion in their center?
What causes a star to live as long as they do? Why do some live much shorter lives than others?
A star's size usually determines how long it "lives". A larger star will contain more fuel to burn and live a very, very long time. A smaller star, on the other hand, contains much less fuel and will burn out after a short time.
Can we create a new element if we create a object hotter than a dying star?
It is possible to create new elements and it does not have to be in an environment that is hotter than a star, scientists have used a particle accelerator to smash atoms into each other in the hopes of changing the atoms you can read more on this website
What would happen if it was the other way around and there was 98 percent other elements and two percent hydrogen and helium?
Why did supernova create elements and how many?
It created elements because the temperature gets so hot the protons can fuse and form new elements. All of the elements in the periodic table were formed at that time.
What would happen if the sun turned into a black hole?
we would die
How fast are elements created during a supernova?
Is there a maximum temperature that a supernova can reach?
Kyra, Supernovas can get up to 6000 times the temperature of the sun
Is hydrogen still made today? If not, are we going to run out of hydrogen someday?
how do protons form and why do they form?
In the diagram of how elements burn in stars, why does Hydrogen get burned first and for so long?
Why do stars skip elements on the periodic table? For instance, it goes from helium to carbon, skipping lithium and other elements.
How does the star white dwarf and black dwarf relate to each other?
Black dwarfs relate to a white dwarf because it is the same as a white dwarf that has cooled sufficiently that no longer emits heat
What is the highest temperature a supernova can reach?
Is it possible that the Sun can turn into a black hole?
Only stars with large enough masses can turn into black holes, and our sun isn't big enough so it would not turn into a black hole.
Why do some stars create black holes?
Stars create black hole once they die out a star with a mass greater than about 20 times the mass of our Sun may produce a black hole at the end of its life.
Are their specific conditions that make a high mass star collapse to create a black hole rather than a neutron star and vice versa ?
Are we close to a black hole
Relatively to us, no.
What happens to the elements after they are created by the super nova?
How does a black hole return to a nebulous state?
From the information I have gathered, there is nothing proving that a black holes return to a nebulous state, so they don't return to a nebulous state. All Black Holes end up doing after a long time is fade away/ disappear.
How are black holes created?
Black holes are created when a high mass star's core collapses in on itself into extremely dense matter. The pulling force of the gravity is so strong that not even light can escape it. For more information on black holes another resource other than the Big History website is http://www.nasa.gov/audience/forstudents/5-8/features/nasa-knows/what-is-a-black-hole-58.html
If temperatures are incredibly high to create elements, could extremely low temperatures create elements?
How is the mass of a star determined?
if we found a way or discovered anything hotter than a supernova, would new elements be created?
pretty much the same as my question, so the answer is yes, it is possible and it does not have to be near a star, people are attempting it now using a particle accelerate.
new elements are created artificially by heating up atoms in a superhot furnace and forcing them together in huge machines called supercolliders'
I want to know more details about black holes.
This website can help you find more information about black holes. http://science.nasa.gov/astrophysics/focus-areas/black-holes/ a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City
How are black holes created and where to the objects go that are attracted by the gravitational pull?
They are created inside of dying stars greater than about 20 times the mass of our sun.
Black holes are essentially areas of extreme density, so everything that goes in won't "go" anywhere, it will just be crushed.
where do black holes come from?
Black holes occur when the core of a star collapses in on itself.
Why do stars turn into black holes?
when gravity wins and the star collapses on itself.
How do we know that elements came from stars and stars burn multiple elements before they die?
hydrogen and helium were used to create other elements with massive amounts of heat.
What (hypothetically) happens when a black dwarf dies, and how?
How does a black hole form?
Black holes form when the center of a very massive star collapses in upon itself.
Can a supernova create any organic material?
Is it possible that the big bang was actually an exploding star?
Why were hydrogen and helium the firs elements? Why not other elements?
When the sun dies out will there be new chemical elements
