The New Telescope Looking Back to the Beginning of Time

In this video, we revisit our recent conversation with Jason Rhodes, the NASA JPL researcher working on the Euclid and Nancy Grace Roman Space Telescopes.
What is the Dark Universe? Neil DeGrasse Tyson tries to arrive at a better name for the mysterious substances making up 95% of the observable universe. Rhodes also explains how the Euclid and Nancy Grace Telescopes are looking back through time to create our most nuanced map of the universe to date.

Thank you producers for taking the feedback on earlier videos and bringing down the volume of the background music. This video was so much easier to enjoy and comprehend. I appreciate you! ❤

[@jeffs6090]

I would go further to say that there's zero need for background music to begin with.

[@jjj76120]

True!

[@andypeiffer5]

I love this additional channel. It's nice to rewatch clips I had forgotten about with nice editing

[@joshinnc1520]

I just can't get enough Star Talk Plus! Thanks, guys, for bringing all this interest content to the masses!

[@Maria-ni4rc]

Nancy Grace Roman was an amazing scientist, and Mr. Spitzer's insightful voice about spaces telescopes has brought us to where we are today...

[@gewoon.dietrich]

Unity is key.

[@baeberry3794]

That was cool. I'm excited about new telescopes!

[@gurdiac]

Great videos! I am a big fan of space exploration and astronomy, but I am also an Earth Scientist. Can we have some "Earth Talk", where we "Keep Looking Around" and learn how the Earth works, how to look after it, how to extract minerals sustainably etc. For example . . . . "How Do We Map The Earth?", "Where Did Those 30+ Elements in Your Smartphone Come From?", "How Did The Plastics Get Into The Deep Ocean?"

[@sidsimon5844]

We often frame our understanding of what the space telescope will do in terms of what we expect to find, and actually it would be terribly anticlimactic if in fact we find what we expect to find. … The most important discoveries will provide answers to questions that we do not yet know how to ask and will concern objects we have not yet imagined. • John N. Bahcall

[@tanbui7869]

I love these videos!

[@AndyRevans]

Loved this! And I particularly like Neil saying maybe Dark Energy should be renamed Dark Gravity, or the other idea of Clear Matter. Either way those names, like Dark Energy, are just Place Holders for something we don't fully understand yet (reference Neil again). I hope we will in my lifetime. The balloon telescopes launched from here in NZ were interesting too. I bet a lot of school and college kids here would be so interested in this. Hmm ... how could we set up a 'StarTalk Plus Local Interest Group in NZ'? Over to you StarTalk Plus!!!! Happy to hear any constructive ideas!

[@mosquitobight]

I can hardly wait until they launch the NDTST

An analogy: When a car tire has a blow out, there is a lot of energy immediately released, and then the tire goes flat as the energy dissipates. This all takes place within a second. What if, at 13.8B years, our Universe is still in that initial blow-out period, eventually calming down? I'm interested in the field of astrophysics, but I don't have the education to answer many of the questions I have.

[@ericdavison6186]

Great discusion; I like his view that the expanding force is 'clear matter/energy' I didn't know about the NASA balloon telescopes! The fact that he says we are are looking at new methods to 'look' at the ancient skys shows what a curious species we are.

[@bored9260]

that concept of matter is looney crazy. clear matter in a high density zone.

[@bored9260]

my father was like they didn’t have any better way of explaining that.

[@Nyli.]

"dark matter is just clear gravity" Alright, I'm ok with a name change, that sounds cool

[@McCoymiked]

Sometimes, when I’m tired, it’s hard not to see dark matter as the force attempting to keep the universe alive by holding together galaxies and galaxy clusters so stars and planets can continue to form and orbit each other, and so that things like life continue to happen. And in opposition is dark energy, whose ultimate goal is to end any chance of even two particles being in relationship to each other. As if dark energy is the ultimate Scrooge and hates all of existence and wants only darkness and oblivion. And it’s winning.

[@coachtaewherbalife8817]

What kind of telescope would be most practical to be affixed on the moon, and which direction should it face?

[@aoifedeborha2420]

You know, one of the things that really scares me after seeing so much uncertainty is what our descendants (assuming we’ll last that long 😅) will think of us and our theories. If dark energy and dark matter actually have a valid explanation for how they work, and of course we are still trying to figure it out, the people in the next few centuries will probably be wondering what took us so long 😂

Why have I never heard of her before?!

[@bored9260]

think about the Hamilton principle dictating the ideas that matter is rough around the edges and rigid… then you look at the atom knowing that matter is opportunistic, which is a smooth orb. like my father said “it goes to show that atoms like to attract all other materials to it.” so when you put both of those concept together and understand that there is no way in hell a black hole can unify a perfect lattice structure… you know it’s crazy…

[@bored9260]

concept of making the point of a unison reaction between smashing and blowing something up became relevant to that point that some great minds get lost in the realm of complexity

[@bored9260]

point of a null field and calling it a temporal lattice in rearrangement of mass and acceleration seems kind of nuts to…

[@bored9260]

temporal lattice would be the idea that time dilation dictates, it would be objectively small and refractive and reflective to see the edges of space, which is far beyond clear over objecting to something constantly…

[@bored9260]

hence the term gravitational lensing.

[@coloradodayhiker]

So, dark energy has gravity??

[@marianagyorgyfalvi3659]

You can still see that you can look into the past, without traveling with your body, you look at your parents and if they don't like what they saw as a child, they look for another fate!

[@RevP369]

Is not space a thing? And therefore it is something made up of other smaller components, maybe at or around plank length particles. As space expands, it “cracks” along the way. Those cracks are the smallest “space particles” breaking, or splitting, thereby, releasing energy = Dark Energy 😮😁🤙🏾

[@charleshetrick3152]

Is mapping the universe at all similar to mapping the human genome to determine if and embryo or newborn is male or female? I mean presumably there’s are objective standards? That’s how we know Pluto is not a planet?

[@melissabrown2192]

🤔

[@TheQuietGamerN7]

Dark energy ..... 🤔 harness dark energy 🤔.... Travel to distant stars 🤔

[@arizona-explorer]

They did a poor job explaining dark matter because we only see the effects of "Dark Matter" and not dark matter itself. The definition of dark matter is still debatable because its hasn't been observed which means we need more people consuming weed to come up with better ideas.

[@igroku2483]

The universe expansion is accelerating, mysteruously? Perhaps we misunderstand there is some unknown displacement taking place. Similar to air bubbles rising from beneath the sea. We do not understand dark matter, nor can we perceive a 4th dimension. Just wondering aloud here.

[@greenjackle]

Hello Fellow Humans, Dark energy is very easy to explain. Think of an endless book being written. Let's use humans as an example. This book writes the day of all humans in it each day. But here is what we don't realize is that with the multiverse you have infinite earths with infinite days. So this book is expanding everyday infinitely. So dark matter may just be quantum time writing each day essentially. In one earth you go left and another you go right and another you stop and another you are asleep. This earth now has 4 more earths in this quantum time with different outcomes. Thus expanding the time book or dark matter. Pushing us more and more. But we are all quantumly entangled with the other universes. Maybe AGI will make it so we can see this quantumverse or maybe time itself. Humans can only go so far so fast. So I for one want to merge with AGI and advance. The human body is not sustainable and is easily destroyed. Plus it doesn't live forever. So you lose the knowledge the humans obtained forever. But realistically before humans can merge with AGI we will most likely go to war and destroy ourselves. Because if the history of humans has taught us anything it is that we are really good at war. But I truly hope we don't and I can merge with robotics and AGI and live until I am done with whatever I wanted to accomplish. Not stopped because time said well to bad you are no longer worth being alive. I say this because I am permanently disabled and I basically don't live my life anymore. I am alive thanks to amazing doctors but that's it. I am not living my life because this society requires money to live. SSDI doesn't pay much so you can't do anything on this little amount except eat and even that is not guaranteed.

[@michaelccopelandsr7120]

What if dark matter is just a pocket, bubble or river of slower moving time and dark energy is faster moving time. One slows down making nothing seem like something. The other speeds up nothing making it seem like energy. One attracts, the other repels. Makes sense to me. Of course, where I come from, crazy is a compliment. ;-P

[@ZeroOskul]

Why do you guys have "gravity" as a property of spacetime is General Relativity shows us it is only Mass interacting with Space that induces Time? Space is time, as SpaceTime, and Newtonian "gravity" has nothing to do with anything, and MoND has been falsified. Am I to listen past ten seconds, after the speaker brings up "gravity" in all seripusness?

The thing about science is that you don’t have to believe in it, it’s true for everyone at all times…NDT Men can be women … also NDT
