What does the destruction of some stars result in?
According to black hole beginnings destruction of some stars results in a booming nuclear reaction.
What is described as the cause of gas and dust forming into a star?
Stars form inside relatively dense concentrations of interstellar gas and dust known as molecular clouds. The deep cold also causes the gas to clump to high densities. When the density reaches a certain point, stars form. Since the regions are dense, they are opaque to visible light and are known as dark nebula.
Which type of star will become a black hole when it dies?
When a star burns through the last of its fuel, the object may collapse, or fall into itself. For smaller stars (those up to about three times the sun’s mass), the new core will become a neutron star or a white dwarf. But when a larger star collapses, it continues to compress and creates a stellar black hole.
Which excerpt from Black Hole beginnings would this image best support in a multimedia presentation?
Explanation: According to the given image, the excerpt from “Black Hole Beginnings” that would best support the image in a multimedia presentation is option A. This is because, as more stuff gathers, its combined gravitation grows stronger and they are attracted to each other which is illustrated in the image.
Which statement correctly explains how the image and text work together to support understanding?
Which statement correctly explains how the image and text work together to support understanding? The image shows the speed and motion of the nuclei, and the text explains why they fuse.
What are the 4 types of black holes?
There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death.
What happens to a star after a supernova?
The outer layers of the star are blown off in the explosion, leaving a contracting core of the star after the supernova. The shock waves and material that fly out from the supernova can cause the formation of new stars. If the star was much bigger than the Sun, the core will shrink down to a black hole.
Will a supernova happen in my lifetime?
It is possible but the odds of a single individual human seeing a super nova in their lifetime using only their naked eyes are low. On average however, a supernova occurs once every 50 years within the Milky Way or once a second somewhere in the universe!
Is supernova a dying star?
What causes a supernova? One type of supernova is caused by the “last hurrah” of a dying massive star. This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers.
How long does it take a star to go supernova?
about 100 seconds
How many stars die each day?
We estimate at about 100 billion the number of galaxies in the observable Universe, therefore there are about 100 billion stars being born and dying each year, which corresponds to about 275 million per day, in the whole observable Universe.
Will we see a supernova in 2022?
Catching a supernova would be a rare and amazing sight: such explosions can shine more brightly than an entire galaxy. Molnar thought he’d found two stars about to explode as a red nova in 2017 — the system KIC 9832227 — which he predicted would happen around 2022.
How does a star fall on its own?
In collapsed stars, matter has been pushed to the limit. In the normal course of its life, this pressure is provided by the energy produced in nuclear reactions deep in the center of the star. When those nuclear reactions stop producing energy, the pressure drops and the star falls in on itself.
Why Earth doesn’t fall on its own?
In the case of the Earth, the weight is supported by the resistance to compression provided by the materials (solids and liquids) that make up the Earth: the pressure is sufficient to compress these materials a little, but the atoms that compose them repel one another and prevent collapse.
What stops a star from collapsing?
Stars on the main sequence are those that are fusing hydrogen into helium in their cores. The radiation and heat from this reaction keep the force of gravity from collapsing the star during this phase of the star’s life.
How fast does a star collapse into a black hole?
This process could take a long time, maybe a million years or more depending on how quickly it accretes the material. Once the neutron star is over the mass limit, which is at a mass of about 3 solar masses, the collapse to a black hole occurs in less than a second.
Can you see a star die?
Probably not. All of the stars you can see with the unaided eye lie within about 4,000 light-years of Earth. But the most distant ones are intrinsically brighter, have more mass and are therefore likely to die in rare supernova explosions.
What event triggers the collapse of a massive star?
The ultimate fate of a star depends on its initial mass. A massive star ends with a violent explosion called a supernova. The matter ejected in a supernova explosion becomes a glowing supernova remnant.
Can a black hole die?
Over time they shrink down to nothing and simply pop away in a flash of energy. It’s not exactly fast. A good size black hole — say, a few times more massive than the sun — will take about 10^100 years to eventually evaporate through this process, known as Hawking Radiation.
Has anyone been in a Blackhole?
Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.
What can kill a black hole?
There is nothing we could throw at a black hole that would do the least bit of damage to it. Even another black hole won’t destroy it– the two will simply merge into a larger black hole, releasing a bit of energy as gravitational waves in the process.
What is inside a Blackhole?
A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.
Do we live in black holes?
Black Holes All the Way Down We can’t calculate what happens in a black hole’s singularity — the laws of physics literally break down — but we can calculate what happens on the boundary of an event horizon. We might live in a universe within a black hole within a universe within a black hole.
Where do things go in a black hole?
It is thought that the matter that goes into a black hole gets crushed into a tiny point at the center called a “singularity”. That’s the only place that matter is, so if you were to fall into a black hole you wouldn’t hit a surface as you would with a normal star. Once it’s there, it’s there.
Is there time inside a black hole?
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole. Inside a black hole is where the real mystery lies.
Where does space end?
No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.
Can you see the future in a black hole?
It’s pitch black — you can’t see it, because it lies in your future, and just like your future you don’t know what it looks like until you get there. But instead of appearing as a tiny point, the huge gravitational differences stretch that point to engulf most of your vision.
What happens when two black holes collide?
When two black holes spiral around each other and ultimately collide, they send out gravitational waves – ripples in space and time that can be detected with extremely sensitive instruments on Earth. If confirmed, it would be the first known light flare from a pair of colliding black holes.
Can 2 black holes merge?
A binary black hole (BBH) is a system consisting of two black holes in close orbit around each other. As the orbiting black holes give off these waves, the orbit decays, and the orbital period decreases. This stage is called binary black hole inspiral. The black holes will merge once they are close enough.
What would happen if a black hole hit Earth?
If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. Eventually, some time later, any object at rest — no matter how far away from the event horizon it initially was — will cross that horizon and encounter the central singularity.
