A supermassive black hole EJECTED from its galaxy?! Plus the B.O.A.T GRB | Night Sky News April 2023

[@ThatBernie]

Wow, the idea of a supermassive black hole just barreling through the blackness of space completely on its own is kind of spooky and amazing all at once.

[@TonyM1961]

We already knew that there were "rogue" black holes flying through space as they have been found and observed. The big question has always been "Where did they come from and why?". Now we may have found the answer, BUT figuring out the actual mechanics of the event is going to be a massive challenge and will likely spawn an entirely new specialty in astrophysics. This is truly "groundbreaking" because until this, we didn't even know that it was physically possible. Sure, the data allowed for the POSSIBILITY, but the forces involved are so intense that it was thought to be "just a fun what if?". Now that we have proof that it CAN happen, figuring out the HOW is bound to be very exciting and important work

[@ThatBernie]

@@TonyM1961 Ah okay, were the “rogue” black holes that had already been discovered supermassive or were they stellar-mass black holes?

The comfortable, cosy setting of your home is perfect for your Night Sky News.. but.. I dunno.. that bright, sunny setting was so lovely!! The echo-ish sound too made it feel more like we're sitting with you in that apartment. No need to change what works, of course.. plus sunny days in England don't exist, right?? But it wouldn't be a bad thing if you ever decided to do the occasional video in similar settings to this one! 😊

After a few minutes of being focused on what she was explaining, I didn't hear the different acoustic effect any longer.

Don't worry about UV coming through your hotel window. Ordinary float glass (a.k.a. green glass) is very good at blocking UV. At 300nm, you can expect 1/8th inch glass to block around 99.9% of light. It will still block 99% down to 260nm. (And if you're wondering, I did just measure it on my photospectrometer.)

only problem is if that isn't glass but a glass lookalike like perspex (PMMA)

[@lonjohnson5161]

@@JamesJordanson I don't know the regulations where she is at, so take this with a grain of salt, but I suspect it is laminated glass, meaning a minimum of 1/4 inch total glass plus the polymer sandwiched between the glass plates. However, it is possible PMMA satisfies local regulations, so it is possible that the window isn't glass as I assumed. Even if the window is PMMA or some other polymer, I would expect it to have UV inhibitors in the polymer, if not to protect the polymer itself (I know PMMA is better than vinyl, but I don't remember if it is completely immune to UV damage), then to protect what is behind the window. Regardless, it is a fair point you made regarding my assumption that the window was glass.

To give you an idea of how bright the GRB is ... we're still detecting it. Like today, six months later. Usually, Swift can only detect GRB afterglows for hours to days. Maybe weeks.

[@ffggddss]

Excellent coverage as always! Just one glitch I spotted - in describing the way a lunar eclipse looks, it isn't the Earth's atmosphere that makes the edge of the Earth's shadow at the Moon "fuzzy;" it's that the Sun is an extended (i.e., not a point) source of light, being about half a degree in apparent diameter. Speaking of eclipses, we're 12 lunations (just under a year) away from the second "Great American (Solar) Eclipse," on Apr 8, 2024. Although I'm not much of an eclipse chaser, I'm already starting to get excited! And BTW, welcome to N. America (Toronto & Huntsville, home of Marshall Space Flight Center)! Fred

[@mikedorward8830]

The difference between the umbra and penumbra in Earth's shadow is best thought of if you imagine yourself standing on the Moon looking back at Earth. If you see a total eclipse of the Sun you are in the umbra. You are also seeing all of the sunrises and sunsets on the Earth in the red ring around the Earth caused by the Earth's atmosphere (which also causes the Blood Moon). On the other hand, if the Earth blocks only a portion of the Sun you are seeing a partial total solar eclipse and you are in the penumbra of Earth's shadow.

[@fademusic1980]

the crazy part is, that black hole was still only traveling 1.19% the speed of light, which don't get me wrong, very fast. but for such a dramatic event it really puts in perspective the difference orders of magnitude present

If it's moving that quickly, I don't think it'd stick around long enough to cause any large-scale gravitational distortion. Probably just capture or eject a few stars along its path and maybe throw out some intense radiation from the accretion.

I've seen it first hand in several scientist, all of whom are gentle, courageous, lovers of learning who have unparalleled humility and place the education of others and the transferring of the flame to the next generations on equal footing with their personal interests and projects. People like Carl Sagan, Stanley Miller, Bill Borucki, Chris McKay and so many many others. Even people like Sagan of whom there is much documentation and we think we know who they are or were, I can attest that they did twice as much work than any one person knows; constant rational analysis for decades while spreading wonder and encouragement to others, truly in awe of the universe and of humanity as well. True, some people can be difficult to appreciate (looking at you, administrative chemists) and don't deserve our affection or professional respect, but their significance as another amazing human existence must be honored.

It's reverb. Echo was originally added to music using a long pipe with a speaker in one end an a microphone in the other, the distance between the mic and speaker determined the delay time. To get regenerated echo the output of the pipe was fed back into the speaker repeatedly until it faded. Reverb was achieved by recording in any room with hard surfaces allowing the sound to bounce off the walls and floors. Starting in the late 1970's effects were added digitally. Even today most reverb selections allow choices such as "cathedral" or "small room".
