Very nice article and great photo!

far out !!

Wonderful post. Thank you for writing this and explaining it in such great detail, yet still in a way that is easy to understand.

I'll be referencing this post for a while.

*Very* well-written article - thanks!

just a tiny comment... black background with white letter on the foreground... very hard and tiring to read...

Something beautiful definitely. Behind this simple photo in appearance there are decades of work, thousands of human hands that worked to bring us closer to one of the greatest mysteries of the universe. Endless thanks to all who contributed to this photo that is already an event.

Wonderful post

Hi Sebastian M. Bobrecki!

Are you trying to ask if both stars in the binary system have the same mass, before and after? That sounds about right, however, both stars do not have to share the same mass.

Giving it a bit more thought, the black hole would be ejecting electrons at relativistic velocities. Or so I've read. Over a vast amount of time, that would lead to what I hypothesize as a scaffolding effect for the non-black hole binary star.

In the case of a visible white dwarf, any nebulous material that was ejected would be caught up in the scaffolding of the black hole ejecta.

The effect would be measurable as no doubt, both stars would continue to be gravitationally bound. The white dwarf would have a light spectrum that can be elementarily analyzed. And if there were periodicity of the light curve, it would be attributed to the periodic eclipse of the black hole.

Just my two cents going into my clubs essay, next month.

Clear Skies!

Professor Lawn: if curved space tells matter how to move, and matter tells space how to curve, then an accretion disc should be mirroring both the shape and nature of the blackhole it question, yeah? Don't maelstroms here on planet Earth do the same? Moreover, what's the one thing missing from within the physical construct of a blackhole's image? A center. Therefore that the Event Horizon has no definable center on which to predicate the inner workings of one of these things, then it stands to reason that it's because there is no center to begin with. What if instead black holes were doorways to someplace altogether different, and not something of infinitesimal size and weight to be positioned where the cross hairs meet? Here's my thinking on this: all throughout the Universe, and on the sub-atomic level where the world of Quantum Physics lie, matter seems to be popping up and into existence from out of nowhere. What if instead this "magical matter" was actually coming from somewhere, like the other side of a doorway belonging to a blackhole where material is repatriated back into the known Universe where and as needed like some giant Pachinko game that uses dark energy as universal conduits, instead of wooden pegs? If dark energy defines how sub-atomic material moves through space, then it has to be that dark matter is telling dark energy in which direction(s) to move it.

This is all hypothetical, of course. It is instead: food for experimental thought. Thank you, and keep up the great work. What's a mind bender for, if not way to straighten another crooked path? All I know is that any journey worth undertaking, whether be it here or out in space, must first start with Mr. Armstrong's, "One small step for mankind." Unless, and of course, you're beholding to the fact that to get anywhere we must first cross half that distance, and so on and so on and so on until "logic" dictates that we should never be able to get where we're going if but for all the halving taking place. Anywho: see you there!

the movie will be great i cant wait.

The stars existed for many years before the event which created the black hole. They were not approaching each other then...

Actually they are approaching each other. If you look closely, on the poster that I linked earlier, for BH scenario at relative time 0 distance between stars was about 5500 solar radius. After about 5.5 million years distance shrunk to about 4000 solar radius and then the Common Envelope phase begins. It stands for another about 700 thousands years during witch distance is reduced to about 40 solar radius. Then there is SuperNova explosion during witch some of the matter is thrown into space. From the remaining matter, a BH is formed. As some of the matter was thrown away and as BH is very dense and have much smaller radius than the star from witch it was created, relative distance rises to about 47 solar radius. After next about 14 million years distance shrunk again to about 46 solar radius and BH begins to draw matter from a companion star, and create accretion disk.

Something I've been puzzling on for decades. All of the mass and energy of our universe started out as a rather small object (singularity?). Surely the density would have been sufficient to put that small object at the center of its own black hole. If nothing can escape from a black hole, does that mean we're still in one?

Great Pink Floyd quote from 'Animals' at the end of your comment. -thumbs up!-

Thankyou for your fascinating article, it is indeed going to be an interesting few years coming up to see where this leads us. It is just a shame that Professor Hawking didn't live to see it !!!!

Thanks for the nice article

Thank you Sir for this fine epxplanation.

Until now I still do not understand wether a black hole sucks up all information, energy and material. When it goes to singularity, is it lost forever?

Second law of thermodynamics creates direction of time. Is this correct?

So where does time go inside a black hole? Does singularity suck it all up, too?

Is it possible that different black holes maybe interconnected through heaven?

Kind regards

Also ich kann auf dem Foto das "Schwarze Loch" sehen. Solche Bilder können aber durch ein "Schwarzes Loch" im privaten PC durch einen Virus unsichtbar sein. Aber ich habe da ein ganz anderes Problem bzw. eine wissenschaftliche Frage. Man weiß heute, daß im Universum nur 20% leuchtende Materie existiert, (auch unser Mond ist leuchtende Materie, man kann ihn ja sehen weil er von der Sonne angestrahlt wird. Die durch mathematische Berechnungen anhand der nicht erklärbaren Geschwindigkeit der Expansion des Raums muß es im Universum viermal so viel nicht sichtbare Masse geben, die so genannte"Schwarze Materie" (es gibt bekannterweise auch "Schwarze Energie"). Jetzt die Frage an die Fachleute: Wie wirken diese beiden bekannten Dinge auf ein Schwarzes Loch? Vielleicht gibt es im "Schwarzen Loch", dunkle Materie.

---

Welcher seriöse Fachmann hat denn von "schwarzer Materie" bzw. "schwarzer Energie" gesprochen? Meinen Sie etwa dunkle Materie und dunkle Energie? Nachts ist es auf dem Land auch dunkel, aber nie völlig schwarz (z.B. wegen Infrarot- und sonstiger Strahlung).

it's good to see that there where people smarter than Einstein around his time it's just a shame that we use the word LAWS when it comes to just 1 persons solutions to a maths problem it seems that scientists today are afraid to question Einstein's laws
