Here's What Happens If You Get Too Close To A Neutron Star

#HowTheUniverseWorks
A neutron star is one of the most dangerous objects in the universe. Neutron stars are the densest things besides black holes. A stone sized piece of this star would weigh 100 million metric tons.

ah okay, my starship is orbiting not too far from neutron star, thx for reminding me not to get to close, im safe now, thx sci channel

Once again, the depiction of the surface of the neutron star is wildly incorrect.

Because of the intense gravity, surface variations are measured at atomic scales not visible ridges like mountain ranges and valleys as it is here. The gravity is so strong that any in-falling matter which hits the surface and is reduced to its neutrons after the protons and electrons are stripped away in a burst of energy, is simply squished flat. Neutron star surfaces are very, very smooth.

"and the violence doesnt end there." I love physics.

Goku definitely want to practice in that much gravity

Really chuck?
You really think it was necessary to dab
When you are going to get pulled apart from a neutron star

Space is scary and cool at the same time....

You can pee without pooping, but you can't poop without peeing. You can't explain that!

Neutron star: *who are you?*

Black hole: *im you but stronger and scarier*

Chuck didnt signed up for this.
He thought there will be a cgi thing happening.
Poor chuck.

That's one way to get rid of the evidence.

*"spghettifacation"* I couldn't have said it better.

1:19 dabbing before death eh?

Respect to that.

• Gravitation
Neutron stars are city-size stellar objects with a mass about 1.4 times that of the sun and 15 km in diameter. Gravity presses the material in on itself so tightly that protons and electrons combine to make neutrons, yielding the name "neutron star. They are so dense that a sugar cube sized lump of material from a neutron star would have a weight of approximately 1 billion metric tons (equivalent to the weight of Everest mountain). Inside a neutron star, there's a delicate balance between the tremendous gravity of the star, and the degeneracy pressure of the neutrons. The neutron star's density also gives it very high surface gravity, more than 200 billion times that of Earth. Neutron stars have an escape velocity of 150, 000 km/s which is half the speed of light. The neutron star's gravity accelerates infalling matter to tremendous speed. The force of its impact would likely destroy the object's component atoms, rendering all the matter identical, to the rest of the neutron star matter. If an object were to fall from a height of one meter on a neutron star, it would reach the ground at 7.200.000 kilometers per hour.
• Starquake and Gama Rays Burst
The crust is composed of broken-up atoms of iron with a sea of electrons flowing through the gaps between them. This crust is extremely hard and very smooth (with maximum surface irregularities of ~5 mm), due to the extreme gravitational field. About a kilometer below the surface, neutrons and any surviving protons are squeezed together so close that they organize themselves into some really odd structures such as sheets, cylinders and others. This inner crust of neutron star, which was called nuclear pasta because of the resemblance of spaghetti and lasagna, could be 10 billion times stronger than steel and possibly the strongest material in the universe. Due to either its ultra-strong interior magnetic fields or spindown, an unimaginably massive quake occurs by ripping the immensely strong crust of neutron star only one centimeter in lenght in a tenth of a second. It realeses much more energy in a form of gama rays into the space through that one centimeter crack than the Sun emits in 150, 000 years. But the inconceivably powerful gravitaional field of a neutron star reconstructs its surface and covers the crack in a blink of an eye. The largest recorded quake was equivalent to a magnitude 23. Had it occurred within a distance of 10 light years from Earth, the quake could have triggered a mass extinction on Earth.
• Surface Heat
Neutron stars are extremely hot and have a surface temperature of around 1.000.000 C degrees. Anything approaching a neutron star too close immidiately evaporates.
• Electromagnetic Field
Neutron stars are characterized by their extremely powerful magnetic fields. These magnetic fields are from hundred millions to quadrillions (magnetar) of times more powerful than the field surrounding Earth. The magnetic field of a magnetar would be lethal even at a distance of 1000 km. The strong magnetic forces would start to squeeze the electron orbits in all the atoms in your body. The molecules that make up your body are only able to hold together when they are made from normal shaped atoms. So once the atomic orbitals got sufficiently distorted, their chemistry would change dramatically and these molecules would start to fall apart. And your body would be reduced to a dusty, incoherent mess.
• Electromagnetic radiation
Most of the light generated by a neutron star is in the form of gama and X rays due to its extreme surface heat, high electromagnetic field and matter acceretion from a near companion. The strong magnetic fields combined with rapid rotation create an awesome generator that can produce electric potential differences of quadrillions of volts. Such voltages, which are 30 million times greater than those of lightning bolts, create deadly blizzards of high energy particles. These high-energy particles (protons and electrons) produce beams of radiation from radio through gamma-ray energies emanating from the poles of the magnetic field. Like a rotating lighthouse beam, the radiation can be observed as a pulsing source of radiation. The pulsar in the Crab Nebula has been observed to pulse in almost every wavelength—radio, optical, X-ray, and gamma-ray. A few dozen pulsars are observed to pulse in X-rays and six are seen to pulse in gamma-rays.
• Rotation
Neutron stars are the fastest rotating objects in the universe. The fastest-spinning neutron star known, which is 15 kilometres in diameter, is rotating at a rate of 716 times a second or 43, 000 revolutions per minute, giving nearly a quarter the speed of light (75.000 km/s) at the surface of equator.
A neutron star wouldn't be able to hold itself together at such a high speed rotation if it weren't its tremendous gravitational force.
