A superb lecture - great to hear about the many observations we still don't understand; there is loads to learn from this method of observing the universe
I still remember the end of that one Battlestar Galactica episode, where Apollo sits in this observatory, and then just after he leaves, it receives footage of the moon landing.
Nah, the aliens will look at that probe image and say 'Aww, look, they were so primitive they didn't know about their Oort Cloud yet. They thought that little thing was a planet'
Maybe I have the mental capacity of 1 billion super computers, or should I just say I'm really smart, but I find it very useful to have some thing concrete to compare the density of neutron star material to. Saying it's really heavy or really dense could just mean more dense than usual. I don't think it would be very helpful to say some thing like neutron star material is very dense and whatever black holes are made of is very very dense.
1 thimble of neutronium (Thats the material neutron stars are made of) would weigh as much as a mountain. A black hole with a thimble sized event horizon would weigh about the same as the moon. There u go, quantified it for you
Doesn't he mistake word universe with galaxy? Milkyway is galaxy so I don't know why he referred to distant - other ones than milkyway as galaxy's. Also when he was talking about arrays of telescopes to produce one giant one - I think he also mistaken radio with telescopic one since he said telescopes. Anyway, very nice lecture otherwise
Your just-after-the-lecture-starts promo plug exhorts the viewer to share. Unfortunately that intrusive just-after-the-lecture-starts promo plug is the very thing that has *_stopped_* me sharing on social media. *_Put it at the end!_*
If it was at the end you would not have heard it. That is why the speaker explains in a sentence or two what his lecture is about. That is an opportunity to decide to listen or not.

Fascinating
excellent stuff

Superb lecture,! Thank you
Free donuts -- worth the wait....
In the probe.. we told the aliens we have 9 planets.. that will be an issue :D
😆
We do 😆

sneaky
what worries me is that if the Borg get these maps we are doomed… “resistance is futile”
