Cool! Two Stars Slammed Into Each Other

[roberth]

Progress, as they say, is slow. In science, this is often true even for major breakthroughs; rarely is an entire field of research remade in a single swoop. The Human Genome Project took a decade. Finding the first gravitational waves took multiple decades. So it’s hard to overstate the enormous leap forward that astronomy took on Aug. 17, 2017.

On Aug. 17, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) detected something new. Some 130 million light-years away, two super-dense neutron stars, each as small as a city but heavier than the sun, had crashed into each other, producing a colossal convulsion called a kilonova and sending a telltale ripple through space-time to Earth.

I can't even comprehend most of what those articles discussed...but it's cool. A teaspoon of neutron star would weigh a billion tons? I can't even fathom something so dense.

Old news. This happened like 130 million years ago.

Ha, I was waiting for something like that!

Pretty cool stuff. There's so much we humans don't understand about the world around us, under us, and within us.

You've not met my wife have you?

[longrange2]

She must be very dense to have married you! Lol.

...and that the last thing I remember saying, Doc...[dig]

That's much cooler than I thought it would be when I read the thread title (I assumed Caitlyn Jenner was driving around Hollywood again).

If Caitlyn crashed it would be because Bruce was feeling her up.

Formation of elements is pretty cool


“With this merger,” Berger said, “we can see all the expected signatures of the formation of these elements, so we are solving this big open question in astrophysics of how these elements form. We had hints of this before, but here we have a really nearby object with exquisite data, and there is no ambiguity.” According to Daniel Holz, an astrophysicist at the University of Chicago, “back-of-the-envelope calculations indicate that this single collision produced an amount of gold greater than the weight of the Earth.”

Looks like EoTech should use the LIGO defense.


When the wave crashed through Earth, it caused a tiny shift in the path of laser beams traveling down long corridors in observatories called the Laser Interferometer Gravitational-Wave Observatory (LIGO), in the U.S., and the Virgo interferometer, in Italy. 1

Misleading title to this post. I assumed it was about Kevin Spacey and Corey Feldman. [ROFL1]

Oh no...it is all settled science. 😀

I’d like to see the outcome if you were ever to show her that post.........

One word- Democrats...

You and I both know HE'S not that dense.

[OtterbatHellcat]

That's cool, Roberth.

Thanks for posting it up.

The mechanical precision and electronic controls for those measurements must be something to see.
