Is Earth Truly One of a Kind? Exploring Exoplanets with Josh Winn [Ep. 463]

Показать описание

Is Earth truly one of a kind?

This question has fascinated humans for decades, and with today's advanced technology, we're finally able to explore it scientifically. In this episode, renowned astrophysicist Josh Winn joins us to discuss the fascinating world of exoplanets, planetary systems, and the quest to discover other habitable planets.

Josh shares the latest breakthroughs in exoplanet research, from unexpected discoveries like hot Jupiters to the ongoing efforts to detect Earth-like planets around distant stars. He also explores the challenges of studying planets light-years away and the exciting future missions that could reveal more about the universe beyond our solar system.

Tune in to learn more about exoplanets and life beyond our solar system!

Is studying exoplanets worth doing even if we never discover life?

DrBrianKeating

What a fantastic guest. I really appreciate the calm overview of the various factors influencing the creation of (exo)planets.

Great discussion Dr. Keating and props to your interviewing prowess lately as you are asking concise questions and letting your guests talk! These last 3 episodes are stellar! Pun intended

Appreciate your videos Dr Keating 🙏
I also really enjoyed how Dr Winn answered your questions. He is a rich communicator.

Of course studying exoplanets is of great worth. We would be narcissist to think we are alone in the Universe. On our Theological doctrines, we have always believed that there is no place where there is no world and the same is applicable to laws. Just because we cannot observe the multiplicities of celestial objects because of time or space(distance) and to limit our mindset on extra terrestrials as humanlike also limits our possibilities of what to expect to see. Life in frozen planets of methane and those in extremes like of kelvin, indeed exist. One would say..prove it...however in order to achieve such, one would have to experience beyond the limitations of a physical body. We are made of three components, Mortal (clay) spirit (higher refined matter) and Mind or Intelligence. In order to seek the answers beyond the test tube and telescope one would have to apply the last two. It has always been our belief that there is no such as 'immaterial matter', hence as you scientists say 'The law of the Conservation of 'Matter and Energy' and that matter and that energy have always existed and cannot be destroyed only altered and if that be the case can any of the three entities of the soul be altered to achieve phenomenon beyond the 5 limited senses that give us result in a limited world or empirical data

I'm going to be writing a science fiction book here pretty soon, so here's a subtitle practice run. Tell me what you think..."A compendium of Stellar companions, from the beautiful to the bazaar.!!?.!"

Dear Prof Keating and Prof Winn.
I throw this thesis on the the table:😂
***Life as you know and observed exist only on earth, therefore Life's entrophy begann there.***
Giving humankind time and resources, you eventually will come to the hint that it is just beginning.
Earthlings can habitate exotic planets!
Universe has to wait over 13, 8 billion years to let Life as such multicomplex that can understand the law of nature!
The only thing, those who go out from earth to colonise exotic planet cannot return in a very long time. communication shall be the only thing that can provide "gegenseitige unterstützung und quasi Nähe Ersatz, als solches "

What do you think of this?
Live you and thank you for the educations❤

What a pleasant video! No kvetching about the state of science and dense discussions that I needed to repeat over and over to understand. Just a nice guy sharing his knowledge. Thank you !

Does the fine structure constant fit Earth, yet it does not have a gradient purpose in Physics-based equations outside our Home? Perception is relative to electron mass here and another planet's elemental gravitational parameters' vs 🌎.

I think we are more likely to have life find us at this point in time vs us finding life out there. As time goes on and we have more good data and new technologies and understandings this will change. But as it stands, we have nothing in the form of good data. We only posses theoretical data based on limited knowledge of what actually causes life to start .

I recently saw a video by Epic Spaceman who tried to show the audience how many galaxies were estimated to be in the visible universe. Whole galaxies. The amount was mind-boggling. Given how many stars and then how many planets that would mean, I cannot understand how we can believe we are the only ones. Especially since we know that we, ourselves, are made up of stardust that is common throughout.

Most stars are doubles. Our Sun is not. Most planets are not doubles. The Earth-Moon system is.

Geoff Merci came up with that in the early 2000’s he should have won a noble prize but unfortunately he got screwed over. Sad he is a great

Bonding angles and lengths + strengths of chemical compounds set at the birth of the universe. Conservation of Gene structure during evolutionary process, Enviromental composition of various planetary systems developed across time. Are we looking for identical planets that can be colonized with minimal work effort ?? (Lazy) ??. And as always development of life. Who says this is the only direction, Always been discussed since the first Sci Fi writers ran for the gold. LOL
