I have understood more about the universe through Dr Blundell’s lectures than ever before in my 60 odd years on this planet. I thank her and wish her the very best with her Global Jet Watch mission. Brilliant lectures. Thanks to Dr Blundell and Gresham College from Australia.
Thank you very much. I have greatly enjoyed all of Dr. Blundell's lectures. I am very sorry that she is leaving, but will hold out hope that she returns with a report on the work she is now setting out to do. [FWIW, I'm a retiree in the central U.S.]
This is the very first time I am listening to Dr. Blundell. It totally disabused me of my conviction that it will all end in a big crunch to be followed by another big bang somewhere somewhen. I totally enjoyed the lecture and will be searching for Dr. Blundell's earlier lectures. One question: in my convoluted way of thinking, isn't dark matter and dark energy the same thing, since energy = mass (i.e matter) ? e=mc² and all of that. (financial analyst here)
The End of the Universe 2128pm 12.6.23 making vast generalisations and assumptions may just be the issue. Maybe science, like any other trusted source of propagating information and knowledge, should desist from making those assumptions. would that mean they would have to admit they know very little as opposed to one hypothetical notion taking precedence over all other notions????
@@JJONNYREPP "The End of the Universe 2128pm 12.6.23 " and above in my thread for this video you posted: "The End of the Universe 2131pm 12.6.23 ". Which is it, 2128pm OR 2131pm? Or is that 'start' 'stop' times of when the universe ends?
It is true. If you pan away from planet Earth, our entire solar system becomes a speck and impossible to even see. Pan out further and our entire galaxy becomes a speck. Eventually the milkly way disappears completely. And this is only the currently observable universe. We can only see ~ a hundred billion light-years of diameter. This distance is unfathomable. And to think that it just goes on and on. What else truly disappears into oblivian, how big are your problems ?
Dark Energy: Modern science claims that energy cannot be created nor destroyed. "IF" dark energy already existed in existence, then it should have already done it's thing. "IF" dark energy came into this existence from another dimension, then from what dimension? And then also, can energy leave this dimension? "IF" modern science is wrong and energy can be created in actual reality, can energy also be destroyed in actual reality? "IF" so, what then of existence in this existence?
The End of the Universe 2131pm 12.6.23 if energy is created from other sources interacting with one another it would suggest it is an organic aspect of the known universe...
@@JJONNYREPP " if energy is created..." It would be interesting how that could actually occur, 'if' true. But then also, what if 'if energy is destroyed'??? What would occur to the universe and our existence then?
@Charles Brightman You're right that energy is not conserved in an expanding universe. "Modern science" is well aware of this, so it does not claim that energy cannot be created or destroyed. Still, the expansion of the universe is slow over short distances, so conservation of energy holds for almost all practical purposes.
The End of the Universe 2141pm 12.6.23 weirdly would folk have to pay for these lectures if they had something new to impart as opposed to giving the samel ecture from 300 years ago...? no doubt 30 years or so ago man city won the treble for the first time...? "match without observations" joke.
Presenter makes constant reference to previous presentations - Those references are largely a waste of time - She could make far better use of her time by actually covering the topic in earnest, and without the constant self-promotion.

You might like Carolyn Crawford's Gresham lectures from several years ago.
You learn some serious word smithing with Dr Blundell. Word of the day: asymptotically
What a great lecture again ☆☆☆☆☆
I could listen to dr. Catherine 's voice, lecturing cosmology ,, forever .

amazing lecture, thank you!
Wish it would hurry up
🤣
Don't worry, it will all be over soon enough.

IF LIGHT TRAVELS AS FAST AS YOU SAY, TECHNICALLY WE COULDN'T SEE LIGHT BEHIND US...
uh I'm waiting on any answer...
I still throw a tantrum when someone takes my nose off of me as well, so don't worry, you're not alone...

QUESTIONS: What is the difference between 'energy' and 'dark energy'? Can anybody see 'energy'? What exactly makes energy 'dark'?

The End of the Universe. 2123pm. Can't. wait. What now until the end? Ummmmm... travel scrabble?
We all dead
We need English language lesson
We apparently were all destined to die and go extinct even before we even ever came into existence.

@JJONNYREPPI’ll have what you’ve had
The Universe, it doesn't end...

Hmmm... Very nice lecture. But, in some critical staffs, I disagree with lecturer. And, I am not flat-earth-er.
You may disagree and we are all agog to see your peer-reviewed paper on your alternate proposal!
It had no start, and it will have no end.
What does flat earth nonsense have to do with this lecture. And what exactly do you disagree on ?
Sorry... I fell asleep listening... are we dead yet ?
you are sleepwriter?
Yes so sorry we are, you can go back to sleep now
You don’t actually exist, you are a figment of my imagination

I believe this is one in a series of lectures, and those references would make perfect sense to the audience she is addressing.
which is why they are even more of a waste of time! @@tonyevans9999
Those lectures are also available here on YT, at least the ones I noticed. No need to go into detail here when she has already done so.
What an egotistical comment.
