Unfortunately, Wayne Campbell, the owner, narrator, and content creator of this channel for over 9 years, suddenly passed away recently. Rest in peace Mr. Campbell, you will be sorely missed.
What are you saying man . Is it true?? I missed his video and thought why he was not so active :( Do this mean we will never able to see videos in this channel?
Thats very saddening news indeed, especially in these times. We desperatly need highly educated and intelligent people today when then Millinneal generations seem so hell bent on reversing the Age of Reason. Actually choosing to be, and/or become uninformed, misinformed, just all aound ignorant takeing the adage Ignorance is Bliss as great advice and a life goal. Those types will live to be a thousand while the best people seem to be called away far too soon and young. I wonder, as some theories in Quantum Physics has theorized, if he is sailing oit there in deep space soon to join that vast reserve or ocean of life energy that is said to be awesomly beautiful, to mingle there until its time to begin another cycle. If so I wish I was zooming along with him.
I'm not so certain. Her discovery seems to constitute rather only a detail. She does not seem to have extensively discussed, experimented, and written.
The man died with 90k subscribers. I just subscribed as one of 195k subscribers. Great work man. You live on and continue to reach people years after your death.
She actually discovered the period-luminosity relationship looking at stars in the magellanic clouds (not near to Earth) by intuiting that they all had relatively the same distance from Earth since they were clustered together. It was then another astronomer who, based on nearer stars, was fist able to calibrate the relationship so that cepheids could then be used for absolute rather than just relative distance measurements.
@@HansDunkelberg1 Interesting that the guy who is best remembered for arguing against the "island universe" hypothesis in his "Great Debate" with Herber Curtis, is also the one who determined that our own galaxy is bigger than anyone thought and that we aren't near the center of it. (Or maybe he's equally well-known for both positions, I only just learned about him and the Great Debate a few weeks ago. It's kind of interesting how much so many books on science talk about all the cool things we know about the universe, but not how we know them).
@@jeffbenton6183 It's, for certain, a good way of enlivening a book on the universe by explaining how such things can be known. But it will be more difficult for the writer, and not everyone might really enjoy it. Similar it will be in the field of biochemistry. You certainly could make a book about effects of pathogens or of cells of the human body interesting by explaining how such effects have been discovered, but your book will grow bigger that way, and for a bigger book a customer has to pay more money. I would not have remembered Shapley to have argued against a universe with multiple galaxies, nor that such a latter notion is called "island universe theory". Thank you for pointing that out!
Is it just me, or ... being able to repetitively capture the "standstill" of stars - standstill enough, that they were able to compare variables within a simulator , is really damn impressive tech ;D
You will not need such a capture to determine the period of a variable. You also can over a longer time record brightnesses at arbitrary moments, draw the results on a chart, and by hand infer a curve.
im not exactly smart when it comes to some of this technical stuff, but it sounded to me like Hubble got to be famous and get awards etc. because of something a woman did first. ill bet the 2 thumbs down this video received is from 2 men that figured that out as well. ;D ....thumbs up from this guy.

Is that true? :'(
Probably. He died September 29th, 2016. Rest in Peace.
andy cai what will happen to this channel

Fascinating! I had heard bits of this, but never the whole story with an explanation of the science. Well done, as always.
6 years later, I too, came to this video for the same reason, and I was not disappointed! Kudos to the people who made this video!
I just saw the play Silent Sky with my granddaughter, (13) and love how this video rounds out the picture, and Henrietta Leavitt's work! Thank you
The best science channel on youtube.
Pity it couldn't reach a million subs
and will never :/ the creator of this channel has passed away :) we hope he will rest in peace
@@bloggervista How can you say this man has passed away? Its very sad news.
@@muhammadhussainsarhandi9928 watch this channel. i have known this channel for ages. its sad but true
@@bloggervista I am also watching this channel for about 5 years, but I haven't seen anything that shows this great person has died.
Henrietta Swan Lewitt should have been awarded with a Nobel Prize for her discovery.
Cheers.
I'm not so certain. Her discovery seems to constitute rather only a detail. She does not seem to have extensively discussed, experimented, and written.
Agreed. Her findings were incredible relevant and significant
Rest in Peace and... Thank You Wayne
Thank you for the explanation. RIP
He became a star itself in 2016.....u will be missed sir :(
yes
rip. :(

You mean Harlow Shapley (1885-1972), don't you?

Thank you for the video. She was a genius to figure that out. I will test it out with my telescope and camera. Thanks.
I love the way you explain the things 👍
Thank you, this explanation has helped me a lot. Regards

Has anyone demonstrated that variability of luminosity could be caused by starspots (sunspots)
Thank you, it helped me a lot!
If apparent magnitude is "variable", what apparent magnitude used for comparing to period-based absolute magnitude? Average? Maximum?
the less it blinks the brighter it gets, and thats why the dim stars are further away. Yes thats my kind of woman.
Andromina Nebula has so much Gold !
You certainly mean the _Andromeda_ Nebula or, even better, the Andromeda _Galaxy,_ don't you?
Thanks...
Make another video plz...
Sadly there will be no videos anymore :'(
That won't happen
He can't. He's 6 feet under the ground in a wooden bin
💖💖💖
could you tell us how to make crystals
+ahmed roshdy Unassisted nucleation reaction, when solute is in the solution.
Meth crystal? XD
