Space-time is swirling around a dead star, proving Einstein right again

The way the fabric of space and time swirls in a cosmic whirlpool around a dead star has confirmed yet another prediction from Einstein's theory of general relativity, a new study finds.

That prediction is a phenomenon known as frame dragging, or the Lense-Thirring effect. It states that space-time will churn around a massive, rotating body. For example, imagine Earth were submerged in honey. As the planet rotated, the honey around it would swirl — and the same holds true with space-time.

Satellite experiments have detected frame dragging in the gravitational field of rotating Earth, but the effect is extraordinarily small and, therefore, has been challenging to measure. Objects with greater masses and more powerful gravitational fields, such as white dwarfs and neutron stars, offer better chances to see this phenomenon.

Our sun will end up as a white dwarf one day, as will more than 90% of all stars in our galaxy.

Dat's rasis!................

[Vaquero]

So...when do we get this honey?

...

Red dwarfs will evolve into blue dwarfs trillions of years from now. Currently, there are no blue dwarfs.

No wonder they’re blue..............................

i believe grumpy is a blue dwarf.

Da moon is cheese!!!!!!!!!!

[Red Badger]

Never.
And don’t call me ‘Honey’!.........................................

“As the planet rotated, the honey around it would swirl “

Kind of like how a Torque Converter works connected between an engine and a transmission.

Garbage.

Charles Q. Choi has no qualifications to write about this subject.

That prediction is a phenomenon known as frame dragging,

That's a good description of this impeachment process.

He didn’t lose weight. He experienced gravitational collapse and got denser.

[Boogieman]

Then when a red dwarf and a blue dwarf are very much in love with each other, they get married and settle down and make little purple dwarves.

...and what qualifies you to write thusly about Charles Q. Choi?

Choi is another Chinese fake!
