1 . how is a black hole formed?
ANSWER : --- 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 formed at the same time as the galaxy they are in.
what is inside the 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.
how does sun emit lights?
The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). ... The amount of solar heat and light is enough to light up Earth's days and keep our planet warm enough to support life.
what is space shuttle?
a rocket-launched spacecraft able to land like an unpowered aircraft, used to make repeated journeys between the earth and space.
1- Stellar back holes form when the center of a very massive star collapses in upon itself.
2- A black hole is not empty, it's actually a lot of matter condensed into a single point. The point is known as singularity.
3- Deep in the sun's fiery core, atoms fuse and create light. An elegant interaction powers the sun, producing the light and energy that makes life possible.
4- Space shuttle is a rocket-launched spacecraft able to land like an unpowered aircraft, used to make repeated journeys between the earth and space.
