What Are White Dwarf Stars?

White dwarfs are basically the burned-out cores of stars. When a red giant expels most of its outer material it becomes a planetary nebula and what remains is the core of the star which becomes a very hot white dwarf with a temperature over 100,000 Kelvin.

@@Cosmoknowledge WHY AND HOW EINSTEIN WENT WRONG REGARDING WHAT IS BALANCED BODILY/VISUAL EXPERIENCE, AS E=MC2 IS F=MA: E=MC2 IS F=ma. Get a good look at the BLUE SKY. The Earth is ALSO BLUE. Get a good look at what is THE EYE !!! Consider THE MAN who is standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is gravity. Balanced BODILY/VISUAL EXPERIENCE is the reason that objects AND MEN fall at the SAME RATE (neglecting air resistance, of course), AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. (Accordingly, the rotation of WHAT IS THE MOON matches it's revolution.) "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity !!!!!!! It ALL CLEARLY makes perfect sense, AS BALANCE AND completeness go hand in hand !!! E=MC2 IS F=ma ON BALANCE !!!!! Think QUANTUM GRAVITY !!!!!!!!!!!! TIME dilation ULTIMATELY proves ON BALANCE that E=MC2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS gravity IS ELECTROMAGNETISM/energy !!! The stars AND PLANETS are POINTS in the night sky !!! Consider what is the speed of light (c). Great !!! E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. Carefully consider what is THE SUN. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) Great. E=MC2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Now, ON BALANCE, carefully consider what is the speed of light (c) !!! The stars AND PLANETS are POINTS in the night sky. A given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out EQUAL AREAS in equal times consistent WITH/as E=MC2, F=ma, AND what is PERPETUAL MOTION, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma. Gravity IS ELECTROMAGNETISM/energy. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Great !!!! SO, it all CLEARLY makes perfect sense; AS E=MC2 IS F=ma; AS BALANCE AND completeness go hand in hand. SO, I have CLEARLY explained why objects AND MEN fall at the SAME RATE (neglecting air resistance, of course); AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity !!! GREAT !!!

Ardit.. you sure got yourself one great narrator there with Russ.. What a team you guys make.. I can't wait for the long ones.. carry on and as always.. stay healthy!

[@Cosmoknowledge]

Russ is the best. You too my friend, stay safe!

I'm eagerly waiting for you to dwell into detailed explanation of the topics you choose to make videos on, through another channel or series, with your amazing way of explanation and all the beautiful, accurate and to-the-point information you provide.

Good job! as usual. Also, the image from Hubble telescope was so intriguing.

Hey Cosmoknowledge, please make a video on quark stars, preon stars and quasi stars.

I'll see what I can do about it. Thank you for your idea!

Eventually, there will only be white and red dwarves populating the universe with neutron stars and blackhole dotted here and there.

Thank you. It is very useful information. By the way what are the ingredients of the black dwarf star? And in a binary system stars what is difference of the mechanism between the white dwarf star become the neutron star after supernova II and become the dust after supernova I ???

how did u know about the gravity of white dwarf, if the temperature is 100 000 kelvin?

[@omaralkhatib3646]

Question: Can there be any futuristic exotic civilizations that use white dwarfs as the last source of energy in a dying Universe?

[@musical-muser]

You said first, at ~1:10 that the white dwarf cools and becomes invisible over the next billion years. Others say that it will take trillions of years, not a billion years, for white dwarfs to stop shining, and you say this as well at the end of the video? Which is correct?

[@arnavjain7566]

Fun Fact: Hubble does not take color photos, it takes photos in black and white. Then looking at the composition of celestial object and temperature, they color it with computer software.

[@Cosmoknowledge]

True!

[@ChristinaMagma]

Interesting!

[@drkido23]

Stars are nearly perfect spheres. But do white dwarfs maintain the near perfect spherical shape or do they become more like our planet bulging slightly at the equator, more an oblate spheroid??

[@Cosmoknowledge]

White dwarfs are pretty dense, they are perfect spheres.

More or less.

if you accidentally, somehow for some reason you stepped on a white dwarf you will literally splash in to a layer of atoms

Kinda like the moon.

[@GovindSingh-kj2tt]

@Cosmoknowledge CAN WHITE DWARF ALSO EXPIERENCE SUPERNOVA?

[@Cosmoknowledge]

They can go type Ia supernova, which means a white dwarf should have another star orbiting close to it so it can accrete matter from it and undergo a runaway nuclear fusion reaction.

[@awaiz1507]

A neutron star creates a supernova or a supernova creates a nuetron star and blackhole ?

[@Cosmoknowledge]

Supernovae create neutron stars.

[@louisjacobs5820]

How do white dwarf stars turn into neutron stars

[@Cosmoknowledge]

A white dwarf comes from the collapse of a star that was not massive enough to implode into a neutron star. However, theoretically, the only way white dwarfs can turn into a neutron star is if two white dwarfs collide adding up in mass.

[@colinbrown3170]

Could a star initiate fusion at the stages of collaps if enough matter is poured into it to avoid it's death? Could something steal matter from our star and help us avoid being burned by a red giant phase?

[@Cosmoknowledge]

Yes it could! Some main sequence stars have been found ripping fuel off their neighbors.

[@bmak7874]

How do we know this for sure? Pure speculation.

[@Cosmoknowledge]

Observations and data.

[@vigneshkrishnan3298]

Do a little longer videos .. good luck
