Stellar black holes form
when the center of a very massive star collapses in upon itself
. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes
What exactly is a black hole?
A black hole is
an area of such immense gravity that nothing—not even light—can escape from it
. Black holes form at the end of some stars' lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.
How is a black hole formed?
A black hole can be formed
by the death of a massive star
. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star's outer layers are blown away.
What is black hole short answer?
A black hole is
a place in space where gravity pulls so much that even light can not get out
. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes.
What are the 4 types of black holes?
And anything that ventures too close—be it star, planet, or spacecraft—will be stretched and compressed like putty in a theoretical process aptly known as spaghettification. There are four types of black holes:
stellar, intermediate, supermassive, and miniature
.
Will a black hole come to earth?
Absolutely not
. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. … It would get very dark of course and very cold, but the black hole's gravity at our distance from it would not be a concern. Is there life on other planets?
Does time stop in 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
. … Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.
Could a human survive a black hole?
Even light, the fastest-moving thing in our universe, cannot escape – hence the term “black hole.” The radial size of the event horizon depends on the mass of the respective black hole and is key for a person to survive falling into one. …
A person falling into a supermassive black hole would likely survive
.
What happens if a person goes into a black hole?
The gravitational attraction of a black hole is so strong that not even light can escape it
. Spaghettification: A black hole would stretch an astronaut's body into a thin ribbon, since the gravity pulling on their feet is so much stronger than on their head. …
What would a black hole do to Earth?
If Earth got close enough, the side nearest to the black hole would
begin stretching toward it
. Our atmosphere would start to be vacuumed up. … If Earth managed to fall into the orbit of the black hole, we'd experience tidal heating. The strong uneven gravitational pull on the Earth would continuously deform the planet.
Why is space black?
Because
space is a near-perfect vacuum
— meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.
What type of black hole is the smallest?
NASA scientists have identified the lightest black hole yet, just 3.8 times the mass of the sun, in a binary star system in the Milky Way known as
XTE J1650-500
. The next smallest black hole, spotted in 1994, weighed in at 6.3 solar masses.
What happens in a black hole NASA?
A stellar-mass black hole forms when
a star with more than 20 solar masses exhausts the nuclear fuel in its core and collapses under its own weight
. The collapse triggers a supernova explosion that blows off the star's outer layers.
What are 2 types of black holes?
Astronomers have long thought that black holes come in just two kinds,
the “stellar” and the “supermassive
.” The type depends on the weight of the black hole, or more specifically, its mass.
What are 10 facts about black holes?
- You Can't Directly See a Black Hole. …
- Our Milky Way Probably Has a Black Hole. …
- Dying Stars Lead to Stellar Black Holes. …
- There are Three Categories of Black Holes. …
- Black Holes Are Funky. …
- The First Black Hole Wasn't Discovered Until X-Ray Astronomy was Used.
What's inside a black hole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don't produce light, a black hole is not empty, It's actually
a lot of matter condensed into a single point
. This point is known as a singularity.
