What two forces are always fighting in a star?
A star’s life is a constant struggle against the force of gravity. Gravity constantly works to try and cause the star to collapse. The star’s core, however is very hot which creates pressure within the gas. This pressure counteracts the force of gravity, putting the star into what is called hydrostatic equilibrium.
Can elements be broken down?
Note that an element: consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and. can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).
Is Kirby a black hole?
No. He is a black living hole. Kirby is not black… He is definitely pink.
How dangerous is a black hole?
These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation. Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in.
How is a neutron star formed?
Neutron stars are formed when a massive star runs out of fuel and collapses. The very central region of the star – the core – collapses, crushing together every proton and electron into a neutron.
Why are black holes black?
A black hole is an area of space with a gravitational field so strong that nothing, not even light, can escape it. That’s why black holes appear black. In some cases, black holes are former massive stars that have been crushed to an extreme density during supernova explosions.
How far away from a black hole is safe?
seventy miles
What is the biggest and last element a star can make?
iron
Is black hole is black?
Surrounding every black hole is an event horizon: the boundary between where an object could escape from the black hole’s gravitational pull and where everything irrevocably falls towards the central singularity. But despite that no objects from inside the event horizon escapes, black holes aren’t actually black.
How were the first elements formed?
As the universe continued to expand and cool, things began to happen more slowly. It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms. These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe.
Where do elements are being formed?
These are the elements that make up stars, planets and everything on Earth — including ourselves. Except for hydrogen and some helium created in the Big Bang, all of the stuff we, and the Earth around us, are made of, was generated in stars, through sustained fusion or in supernova explosions.
Can we create elements?
A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called “synthetic”, “artificial”, or “man-made”.
Can gold be created?
Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements.
What if we go into a black hole?
If you jumped into the black hole feet first, the gravitational force on your toes would be much stronger than that pulling on your head. Each bit of your body would also be elongated in a slightly different direction. You would literally end up looking like a piece of spaghetti.
How are elements up to and including iron formed?
Elements up to and including iron are made in the hot cores of short-lived massive stars. There, nuclear fusion creates ever-heavier elements as it powers the star and causes it to shine.
Which is biggest black hole?
Sagittarius A*
