But far too many "Joe Averages" get defensive, into denial or start making fun of what they don't understand.

This is the first time I have seen your show, but it won't be the last. I laughed so much it hurt. I have been watching Dr Becky's RUclips channel for about a year, and I must say hearing her swear has been the highlight of my day🤣🤣🤣 Please keep up the great work.
This popped up in my timeline, it’s such a funny and irreverent look at Astro Physics it’s great. Love Doctor Becky and her work. I’m glad she didn’t initially confuse them with hawking radiation
Absolutely brilliant. Dr Becky explaining complex matters in such a way that even I could understand was a real ‘eye opener’. The three of you made my day by being so infectiously positive as well. A complete WOW of a topic. Well done guys ❤
Opening assassination on Astrology "Mercury has been orbiting the sun for 4.5 billion years it doesnt give a fuck what we do down here" ...Solid. Gold.
Dr Becky *rocks* hands down. RUclips suggested this since I am a long-term subscriber of Dr Becky, she's here so this should be good and I'll give this channel a try.
First time listener thanks to Dr Becky. When Dr Becky was talking about the size of the universe I was waiting for her to wrinkle Joe's brain and talk about how the universe is expanding but the observable universe is shrinking.
Welcome to the world of a modern academia ;) You have to have those skills when doing something like a PHD level degree, at any large top university, or being a lecturer at such Uni. And if you don't have them... you will at the end ;)
Loved this. These are the very best kind of conversations ❤ Find someone with literally no grasp of the subject but who is kind, respectful and genuinely interested, because they will ask the best questions that many are afraid to ask. There’s no better way for a true expert like Becky to be challenged and engaged than by asking the most fundamental questions 👏🏼
Dr Becky you are worthy of a Nobel Prize for the way you bring astrophysics to the laypeople. I’m 73 and you make me wish I had gone down the same path as you. I now enjoy listening to you wonderful lady.
Dr. Becky is one of my FAVORITE RUclipsrs, Hands Down, Top 5. Do you have ANY IDEA what I would do to just ask Dr. Becky questions for 5 minutes? You guys are SO lucky.
She played an important part in the pre-cursor to wi-fi, but not wi-go itself. To be fair, she had no formal electrical or electronic training, yet through her own personal research she was able to learn more than most graduates. Amazing woman.
10 min in and I'm crying laughing. This is some Karl Pilkington level funny stuff😂 Everytime there's a question starting, you can see her bracing herself "Oh, oh, here it comes. Here it comes"😂😂😂
I am so grateful to YT for bringing this video up. I loved the chemistry between all three of these guys. Dr Becky is always so charming and was a perfect guest.
Him: "you want me to spit on you?" Her: "why not." what a great science communication show. genuine laughter with interest in information about the universe. loved this so much.
I really enjoyed this. Watch Dr Becky's youtube channel. In this interview she came across as a very humble person who gets great pleasure in explaining the complex issues simply.
@DrBecky I enjoy so much the content you post online and I also loved this 1hr podcast and when I saw you book on Audible that is also narrated by you I had to purchase it. Near to 8hrs of Dr Becky patiently explaining Black Holes to me was fantastic. Thanks for all the contribution you are doing not only for the scientific community, but also in educating Us, "Dummys" on the subject and sparking the love and comprehension of the universe.
I loved listening to this upload due mostly to hearing Dr Becky's priceless kookier side(s) while she was laughing with the kooky hosts of this RUclips channel. 🌸

@@mlguy8376 Smart lad absolutely agree but he’s got the charm and charisma of a British Rail cheese sandwich. Dr Becky on the other hand just managed to teach high end physics to two lads pretending to be primates. There’s got to be a slot on The Sky at Night or Stargazing Live for her. We want to get girls into STEM?. Here’s your answer…and she can swear!
@@SteveJones-om6ks I am a strong supporter of dr Becky, I am fully subscribed to her channel and watch it religiously. Yes, I did my undergrad in maths and physics, when there was 3 women studying - we have made improvements, but women in stem has been a thing since circa 2003/4 and we should keep doing so (that ratio massively increased for astrophysics group when I did my PhD) dr Becky not only shows that women are and should be studying Physics (I feel stupid even writing that last sentence in the 21st century) but she also comes from the north (and I have not checked this so I do apologise in advance) a normal class background which I think is even more of a stigma at the top unis) - with that being said, we should as many people supporting physics and scientific knowledge - as you know, we all seem to be surrounded by lots of people driven by incredible poor scientific knowledge - from 5G to how vaccines even work. Sorry for my initial comment, it was rather snarky. Both cox and Becky can and should have a platform on TV.
@@mlguy8376 It was fair comment!. I’m from Liverpool so I’m biased against anyone with that accent!. In fairness I do like the stuff he does on Infinite Monkey Cage but the tv shows irritate!.
Science communication as it should be. An entertaining and easy to understand explanation of something very complicated indeed! This is what the world needs more of!
Dark matter: A hypothesis used to explain away phenomena for which we currently don't have a better explanation. No one has metaphorically put their finger on anything they could say is dark matter.
I am so envious of these two, self proclaimed "idiots", of having a multi hour chat with such a brilliant science communicator as Dr. Becky Smethurst! It's a shame that they didn't ask her harder questions, but I thoroughly enjoyed every second of it! If I had an ounce of the charisma these two have, I would start a podcast hoping to someday have such a guest. You guys should look into convincing Neil deGrasse Tyson to come chat! Or maybe both at the same time, having them play off each other. However, you might have to reign in some of Neil's energy... Their energy levels are far different, but I love them both! Anyways, great chat! Will be watching more, now that I know of you!

Talking about dark skies with no light pollution.2months ago i was in the Australian outback 200 km from the nearest town and the night sky was incredible.
Love this interview. You guys are clearly wowed by the amazing Dr Becky, and at the same time she’s clearly enjoying the irreverence and playful mood. Fair play Joe - breaks the mould this. Buy yourself a telescope and you’ll never look back!
But, I have to say that while Columbus was totally wrong - North America is _not_ India :) - If he hadn't started out on his journey, the world today would be a much different place. If North America had not been there, he would have died mid-ocean along with his crew. Careful does not win the prize.
I see a lot of people who have no real grasp of science confronting people who have made science their life's work, assuming that the notion of science they just got 15 seconds ago is not only equal to the scientist's understanding, but might even be better. I wish that there was so much more of what is happening here, where the guys openly admit their scientific understanding is not great, but are willing to listen to the expert, acknowledging that her understanding is a great deal higher than theirs. It is about refusing to allow ego to get in the way of learning.
Einstein's theory was that time would "seem" or "appear" to move slower, i.e relative to you, but that assumes the traveler is looking at some clock which as you speed away, the photons would take longer to arrive to your eyes. However, if you have a watch on your hand, it would tick at the same speed as another watch on earth. Basically, it's a visual illusion of time dilation. Somehow, we are confusing that to mean that time is therefore going slower. Its all about temporal perspective and light speed illusion. The argument for atomic clocks in space vs earth is also flawed as gravity affects atoms and subatomic elements differently based on proximity to earth's core versus in orbit. Just in case someone wants to bring that into the convo.
One misconception that could be cleaned up is that it is not true that in general Christians believe the universe is only a thousands of years old. In fact the original version of the big bang theory was proposed by a Roman Catholic priest. "This startling idea first appeared in scientific form in 1931, in a paper by Georges Lemaître, a Belgian cosmologist and Catholic priest." Frankly I am surprised that Dr. Becky did not know that.
I have known about the concept that traveling fast makes time pass slower for you. But what frame of reference is it based on? If I am traveling past earth, from my perspective, earth is moving the other direction. The earth is not stationary, it's orbiting the sun and the whole solar system is orbiting the center of the milky way. And the milky way is moving relative to the other galaxies in the universe.. But then when I travel fast, how is that different? What is the overall frame of reference that determines how fast time passes for each observer?
I am not an expert but as I understand it there is no such thing as an overall frame of reference. Hence the word “relative”. Everything is in its own inertial frame of reference and so we can only compare two things in their relative motion. Time is slowed by speed and by gravity. To have a big effect it’s got to be a significant percentage of the speed of light. The motion of the earth sun and galaxy is nowhere near the speed she was referring to…. Needs to be say 1 or 2 percent of light speed. So the earth the rocket leaves behind does not experience the acceleration that the traveller does. They are therefore not the same. So the accelerated pilot is the one that experiences the slower time. Even though to her it looks like the earth accelerated away, so she might expect earth to experience the slowing of time. But earth did not accelerate…. it did not experience the higher relative velocity and hence the slower time passing.
Yeah, the standard explanation of relativistic time dilation really oversimplifies what's going on and leads to apparent contradictions like this. And it's so long since I last looked at the proper analysis of the "twin paradox" that I'm not gonna risk botching the explanation here. And it really doesn't help that people keep mixing it up with *gravitational* time dilation, which is completely separate, and is what's shown in "Interstellar".
Things get crazy when you consider the limitations of the speed of light. Gravity also works at the speed of light. If the sun were to turn off we'd not know it for 8 minutes. If the sun were to disappear completely, just wink out of existence, we'd still continue orbiting the place where the sun was for another 8 minutes, until the lack of gravity reached us. Neptune is about 250 light-minutes away from the sun, so it'd take Neptune 250 minutes to fly off into space if the sun disappeared.
Can someone give me the timestamp of where she talks about going to mars? I can think of many ways I agree.. but am still a big space settlement enthusiast. Might be here: 48:25

Love Dr Becky! Her enthusiasm for space is contagious and she does such a great job explaining incredibly complex things!
I could listen to Dr Becky all day! So interesting
Dr Becky is simply awesome. I’ve learnt so much stuff watching her channel. Her bloopers are a blast as well.
Hey , I've always thought she has a nice pair of bloopers too but I don't think we need to go there ......
Hilarious how Joe puts his hand up to ask Becky a question 😅
Brilliant video, love it

you learn things EVERYTIME
Thank you Becky
Nice to see Becks not just talking to herself for a change. Good chat.
Dr Becky said "Fuck" err my gerrd lol 😆👍🏾‼️ She's awesome, Carl Sagan would be proud 🥲‼️
Its shocking innit
The horror.
I was going to say the same thing!
Dr Becky is the shit, verbatim
you mean Carl Sagan
Love Doctor Becky. ❤️
This interview is a real treat.
A lot of interesting questions are being asked
agreed. especially to see her in a live conversation setting in comparison to the scripted video content on her channel.

One of the best things about my job is it takes me into the middle of nowhere and I get to see incredible skies.
What job is that? Sounds interesting!
Astrophysics aside... that Joe seems to kinda understand some of these concepts is what is mind-blowing!!
She is breaking it down into real simple terms. I would sure hope he would be able to understand it.

That was so cool . I got see a very different side of dr Becky. Prettiest science geek in history.
Wow! This is great, two of my favourite personalities on the same pod!
Fantastic show, thanks for posting.
Follow Dr Becky and like a bit of rugby so know of Joe never in my life thought these two worlds would collide absolutely loved it
Dr beccy is lovely and it’s great seeing joes mind being blown.
This was awesome. Watched the hole thing from start to finish on one go. We need more dr Becky 🙂
Watched the "hole " thing.. I see what you did there 🤣
Dr Becky, Well done. Mainly for staying so professional during this podcast. 😂
Wow, this was only recommended to me 1 year after, out of the blue. It was great! 😄👍
