Mysterious Blast From Most Distant Galaxy Known, Finally Explained

Hello and welcome! My name is Anton and in this video, we will talk about last year's detection of an unusual gamma ray burst from the most distance galaxy ever found - GN-z11

Anton keeps me coming back to YouTube daily.

Clarification to one point:

The light has travelled about 13 billion light years since it was emitted.

The 32 billion light year distance is not what the light travelled through. The larger figure is because the universe has been expanding so that after the light travels towards us through some distance of space, that distance behind it increases. Of course the distance between us and the light has been increasing since it was emitted too, meaning that the galaxy was closer than 13 billion light years when it was emitted.

Pretty much by definition though the light itself has travelled through 13 billion light years of space.

Science teams, play by play action in their field... Anton in the booth keeping it honest and wonderful.

[sharonsimcic]

Thank you! Glad you're back and hope your move went well.

1:56: The light did travel 32 billion light years? That would have taken 32 billion years which is just impossible as the age of the universion is 13.4 billion years. So when the galaxy was observed at a point in space and time where the universe was .5 billion years old, the light travelled some 12.9 billion years.

As space expanded since the light was emitted, today's distance of the galaxy would be 32 billion years (estimated of course, we can't measure it).

[joeortiz]

Very interesting, enjoyed this lesson !thank you Anton!

[xIPatchy]

The light didn't travel 32 billion light years to reach us. That is the relative distance between us and the galaxy the light originated from, today. the light we are seeing today traveled 13.4 billion light years.

Normally Anton releases content ahead of other channels, but for the first time EVER I just saw physics girl do a video on this a few hours earlier. Edit: actually hers was more focusing on the distance and age of the Galaxy in question

Interesting interaction between the first paper's writers and the second paper's writers. Not often we get to watch the interplay between two different "factions" in a scientific community in such detail! Very cool!

[hummakavula]

Are we so quick to rule out muzzle flashes from intergalactic doomsday weapons?

[davejones]

One of these days, Occam, I shall turn that razor against thee!

[sonarbangla]

If we get spectral analysis of such bursts, immediately it would give us valuable clues about early universe.

[adzaaahhh]

This sounds to me like a typical case of Occam's razor. According to the laws of probabilty, the most likely explanation is usually the correct explanation.

Anton’s a good communicator, very easy to listen to. I’ve been kept well informed over many space topics since I have discovered this guy a few months ago. Thanks for the education on my favourite subject. 🌌

[MCsCreations]

Well... It can be rare, but shit do happens. So... Who the hell knows, maybe it was a coincidence.

[doresearchstopwhining]

Hey @Anton - You should do a video about a meteorite that landed in someone's bed recently. Crazy stuff. I wanna know how that happened, the odds, the chemical make up of meteorite. You know, all the stuff you know about. Do it!

[TalkinKush]

I can’t wait for the James Webb to launch !

[iLLeage]

Holy space shit Anton you're almost at a million subs my friend! Frickin grats in advance homie

[ganzrawr]

Anton I look forward to the day you get to 1 million subs! You're really close. Keep up the great work!

Lucky 76 :)

Thanks Anton!
