I think thousands of years later you'd still be wishing the same thing. The current questions may or may not have been answered by then, but I'd like to think that there would simply be a whole bunch of _new_ questions in need of answers.
fuck i hope that this wonderful human specie of ours will be extinct in 1000 years! at least, gone from earth, let other things grow here. we-re like fkin cancer. or not... i don't know, maybe we should stay and fuck this planet up totally. i don;t know...
With half a million subscribers, I was hoping to have atleast one cosmic journey video per month... but it's been 6 months now ~ sad face ~ Just have your amazing narrator & space visualizations & it's gold.
A month?! Tom Lucas's production is easily the most premiere content, most on the internet, in this genre. It takes a lot, a lot of work, research, involvement of experts and institutions, time, effort and money to create content like this. If you produce two to three of videos like this per year, you are doing well.
Info like this makes me believe in miracles. Millions of them in just the right sequence. Sometimes I feel small and unimportant - especially having been sick for so long. This is like therapy. If life and the universe doesn’t boggle your mind, or at least fascinate you, you’re just not paying attention. I love the wonder, amazement and mystery of it all. It makes me glad I was here for a while.
It is very fascinating to hear more about these emerging star systems that we have observed, where we can literally watch planets be born. I understand that the process is far too slow for a single human lifetime, but I am sure we will continue to observe, generation after generation.
I agree, it is fascinating. As for the process taking longer than a human lifetime, that's my understanding too. I'd never want to life forever, but I've always thought it was be cool if we were somehow able to make 'periodic return visits' to be able to check up on how humanity is going (if we're still around) or how our descendants are going and see if we've managed to solve some key issues, or whether we've solved the Fermi paradox, etc!
This explanation is much easier to buy into then black holes! And it also seems that Velivkosky is finally getting some respect. But the whole thing that brings it all together is Dick Rodstein. Another most excellent production.
You realize to see other planets in real time, you have to be at that planet? Anything we view in the universe is the past. We see the sun 8 mins in the past. We see the gas giants, hour or more in the past.
Though bathed in conjecture speculative thinking and clouded with theoretical explanations, This documentary style presentation represents an intelligent and noteworthy view of our solar system and other possible solar systems. All enhanced by fantastic HD visuals, and clear flowing diction by the narrator. 100% full marks.
It's disheartening to think that relatively stable and orderly solar systems such as ours may be rare. If it turns out that "super earths" dominate the life zones of mid mass main sequence stars, the only hope for their habitability is if they possess large moons in abundance.
Yeah that was clearly Minecraft. I was wondering myself why they put that in there. Was that really the best CG model of that type of city they could find? Weird. Otherwise fantastic video.
I have a question. I heard that the Kepler telescope finds exoplanets by the shadow they make when they pass between the telescope and the planet's star. But what if the exoplanet's orbit is not passing between us and it's star? What if that system's disk is angled differently than the telescope's point of view?
amir halperin Let me use the Sun as an example. Generally, when we say that all of the planets in the Solar System orbit the Sun, we really mean that the planets are orbiting around the Solar System's barycenter. The barycenter is the point at which the center of mass of two bodies is located. The more similar those two masses are to each other, the farther the barycenter will be from the primary mass. For example, Pluto's moon, Charon, is a significantly large portion of Pluto's mass, so the barycenter of the Pluto-Charon system is located about 960 km above Pluto's surface. Now, because Jupiter is the most massive planet in the Solar System, it has a large influence on the Solar System's barycenter. This causes the barycenter to be located at about 46,000 km above the surface of the Sun. This means that not only are the planets orbiting the barycenter, but also the Sun as well. So, if stars have other planets orbiting around them, then their barycenter's can be measured, allowing us to figure out the mass of one of the planets. This is actually how the planet Proxima b was discovered.
amir halperin I would also like to add that the barycenter doesn't necessarily have to be located above the surface of the primary. For example, the barycenter of the Earth-Moon system is located 1,710 km BELOW the surface of Earth, (which is still 4,670 km from the center of Earth).
There used to be a Maldek in b/t Mars and Jupiter that exploded and left some debris behind to form the asteroid-belt. It's also said there used to be another sun that was moved away from our solar system to slow the evolution process down.
Religion has turned Iraq from a world leader in science and understanding to what it is today. This fact is heartbreaking. Religion pulled Iraq from the frontiers of mathematics and astrology back into the dark ages. This was a great loss.
@@kosys5338 Yes, this is true -> Iran, then Qatar, Saudi Arabia and Turkey 4 countries / I have destroyed Iraq and killed the people of Iraq / My older sister went to Germany, she is a doctor and a chemical scientist: My brother is a cardiologist who went to Belgium: My father also went to Belgium: I am the only one in my family. I did not complete my studies : But I used to make electricity, but there are many reasons that made me burn all the papers that were planned for electricity / We are 4 brothers and my sister is older, we are all outside Iraq
@@kosys5338 In Iraq, many scientists and doctors have been killed and those who know about science: Iran, Qatar, Saudi Arabia and Turkey: Many scientists and doctors have been killed. They do not want qualified people. They want a weak people: all the politicians are followers to countries who are agents to countries: there is a young man who made an electricity machine Great: This young man was killed / There is a young man who made an engine that makes water. We add: This young man was also killed: There were 10 doctors helping the poor with free fees 10 doctors were killed: I mean that Iran and Qatar destroyed Iraq, America presented Iraq to Iran and the rest of the countries
Mass Extinction seems to play a major role in life evolving into more complex forms. Calamities from space are becoming rarer, so nature evolved a species that could produce one for it. Then, once we kill ourselves off, our planet will start the slow process of planetary restoration (thank you photosynthesizers, methane-eating bacteria, extremophiles, etc.) and nature will use the remaining surviving animals & other life forms to create a completely new tree of life.
0:50 Not necessarily. With the way we are looking for planets, the most likely sort of sustem we will find is the ones with hot Jupiters. These are the easiest sort of systems to find, so we will find those sots of systems first. If we want to find a solar system like ours it would take a least 50 years, the time it takes Jupiter to orbit twice. In that 50 years we are likely to develop our technology so that we will discover more efficient ways to discover planets.
Actually, what this video is saying that even with over 5,000 exoplanets discovered, earth could have formed around none of them, because the “super-Earths” and “Hot Jupiters” are so close to their parent star that they would fling and earth sized planet out of the system or absorb it. I find it disturbing that people abandon scientific skepticism when it comes to alien earths and assume that they are plentiful instead of saying “prove it!”
I call out BS, us finding planets so close to their star, and huge planets, is due to our limitations of observation, we just don't have the means atm to observe smaller planets and planets farther away, or out of the same plane for observation. Should we be able to change this, we might find solar systems more similar to ours.
It’s astounding when you find out how much of scientific advancements and discoveries took place in the ancient Middle East….. They once led the world in progressive educative pioneering….
Our star's name is often called Sol, its Latin name (hence, our system's name: "Solar System"). Though many/most scientific associations do not recognize an official name. Though "Sun" is considered a common name of our star in modern English, as well as a referred planets parent star in reference to ours. Example: The alien planet's "Sun."
Basically referring to other stars in other solar systems. Basically calling a star a "sun" in ours and another system is the same thing as saying a star
Irrefutable Truth the James Webb infrared telescope was due to launch this fall, but I think it was delayed to early 2019. Freaking hope the launch and deployment will work 100%, because it will possibly provide mind-boggling images. It's extremely complicated and so many things can go wrong. I'm not gonna have one fingernail left after a hopefully successful deployment.
fine , i have doubt what is the direction of earth planet , while sun is getting raise on particular longitude/or particular doubt , may be my doubt is silly , i want to get clarified at the earliest.
So life on 🌎 is a result of many fortuitous happenstances. A+ b - c = d. The formation of certain planets & their resonances allowed Smaller earth like planets to form.
Because of the immense pressure. Mostly. Some minuscule amount of warmth is generated through nuclear decay. There is also some speculation about the effects of solar activity on our planet's metallic core, as there supposedly is a pattern of large solar eruptions being followed by larg earthquakes with 1,5-2 month delay.
"For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else" (Isaiah 45:18).
