Thanks so much for watching!! #reaction #astronomy Original video: • How the Universe is Wa... Help support the channel: patreon.com/user?u=87622625&u...
When it comes to the question of, "Are there other lifeforms /intelligent beings somewhere in the Universe ???" The same man that made the Quote about Earth being a speck of dust suspended in a sunbeam, Carl Sagan , also said , " The Universe is bigger than anything anyone has ever Imagined & If we were the only ones, It would be an Awful Waste Of Space." 😉
You are right about the diameter thing. This is what I get on Google. "The Moon's diameter is about 3,500 km, more than a quarter of Earth's, with the face of the Moon comparable to the width of Australia. The whole surface area of the Moon is about 38 million square kilometers, between the size of the Americas (North and South America) and Africa." It also took Curiosity Rover 7 months to get to Mars. So it is quite far
that little yellow dot at 8:26 showing furthest extant of our radio signals.... thats about 100 light years diameter and includes nearest star 4.2 away they just used as example of distance
I'm still totally blown away by the size of our Universe! As a builder when I measure something out I sometimes think "Dude" the Universe is way longer than 2 meters?! True Story..
But could actually measure that correct? ““Here’s the extent of what we can see.” Then they zoom out 4 times? So what camera is that far away? Any idiot can do the same shit. There’s an app for that…if Voyager can see it? Cool, I’m in, but some liberal fuck with some PowerPoint presentation? They were one zoom away from Michelle Obama being attractive….but that’s beyond comprehension and what PowerPoint is capable of…PowerPoint can make people believe things to be true, when it’s just a hypothesis, but it can’t make Michelle attractive. Even PowerPoint’s like, “Fuck that”….
As much as I feel sad about Pluto being kicked from it's planet status, because we all learned it in school, I have to agree. Our moon is bigger than Pluto. Even some astroids are bigger than Pluto. Its status as a dwarf planet, as much as I hate to say it, is more than fair. The hardest part about making a map of the universe is actually making a model of our galaxy, the Milky Way. It is hard to map it out and make a make an image since we are inside of it. All the other galaxies are easy to depict and show since we can see them from outside.
Oops didn’t cut the first part out 😐 buuut anyway if you’re into astronomy and stuff I highly recommend listening to and looking up the lyrics for bts’ 134340. They kinda personify Pluto and use it getting kicked out of the solar system as a metaphor for still longing for someone after a breakup.. idk I know how most people feel ab bts but if you give them a chance they really have amazing songs with AMAZING lyrics. 134340 lyric translation here: doolsetbangtan.wordpress.com/2018/06/01/134340/
The only reason Pluto got kicked down to Dwarf Planet status is because of it's location in the Kuiper Belt an asteroid, other space rocks, ice, belt past Neptune orbit it passed 2 of the 3 criteria needed to be considered the official 9th Planet, it passed the 1st criteria orbit around the sun, and it passed the 2nd criteria being a large round object but failed the 3rd criteria for its location in the Kuiper Belt, just like Ceres and MakeMake they are both Dwarf Planets that orbit the sun and are round objects but they being located in the asteroid Belt failed them from being an official Planet. They are still The Sun planets just not official 1-8 status just Dwarf Planets
Just to clarify, Voyager 1 was launched on September 5th 1977, and never passed close to Pluto. The Space probe you thought of is New Horizons, launched on January 19th 2006 and reached Pluto in July 2015.
The light hasn’t reached us yet. Just think how fast the speed of light is to us it can circle the entire earth in less than a second….let that sink in. It’s the fastest speed we know of and yet it’s taking millions of years to travel through space 😬 that all should tell you how big the universe is lol
A common misconception is that "nothing became something", but in reality the concept of "nothing" doesn't exist. There is never a nothing and was never a nothing. At one point all the matter in the universe was condensed down into a singularity. We can even pinpoint where in space this singularity was. For some reason the singularity started to expand. There was never a "big bang" and that is a bad description of the event. It is better to describe it as an "everywhere stretch". Of course all matter being condensed means it was extraordinarily hot when it first expanded. This leads to bonds and fusion events of different molecules. Hydrogen was of course the first as it is the simplest. It also happens to be the most reactive because of this. Almost all stars start their life as hydrogen being condensed together with gravity. Through more and more pressure as more and more hydrogen comes together things like nuclear fusion kick off. New elements start to fuse into existence. When these stars go supernova as they start to produce iron. Iron really messes everything up. The star can no longer sustain equilibrium and the core collapse in on itself causing a supernova. This spews these new elements all over to come together and make larger stars which have more pressure that make even new elements. A lot of stars formed at the start of the singularity stretching. Lots of elements formed pretty quick. Through these many many supernova you get particles of elements to combine into large chunks of themselves and thus we have asteroids, planets and moons. Ever wonder why our solar system is the way it is? Why do we have rocky planets in the center and jovial planets outside of our solar system then? It's because of thermal gradients. As you get further from the star you get colder and the solar winds get less powerful. Close to the star rock won't solidify so you have a gap between sun and first planets in a system. There's a limit to where you can have terrestrial planets those being Mercury, Venus, Earth and Mars. You then get to a certain point where you can have liquid water and thats where our planet is, the "goldilocks zone." We aren't special for that either. The goldilocks zone is millions of miles wide. It's a common myth that if we were a foot closer or further we couldn't survive and that's simply not true, but I digress. Past a certain point the solar winds blasting the planets weaken. That's where we get these big gas giants. All the gas that's around Jupiter, Saturn, Uranus and Neptune would have been here on Earth too, but the sun blasted it off to the back of the solar system. That's why the gas giants are out there. And if you look at any other star system it follows the same format. No planets in front, the terrestrial planets in the center and the gas giants, if it has gas giants, in the back. This all happened after a supernova from a dead star created our sun, and the suns gravity attracted material from said supernova. All star systems are from generations of stars dying and being born. This all happened and created all the protoplanetary disks of various materials. Heavier stuff closer to the star and lighter stuff further away. Over time they became what we know them are today as they clumped together. One of those protoplanetary rings became Jupiter and if it were two times bigger it would actually become a brown dwarf star, the smallest star. It is already so big that it stopped us from having another planet. The asteroid belt is a protoplanetary disk that could have been a planet, but because it was stuck between the Sun and Jupiters massive gravitation it was torn apart.
interesting again, like yesterday , my comments would only touch on subject, drop in bucket on an in depth conversation. enjoyed this , but will not get carried away on comments. like your choices, keep it up. always glad see your reaction. see next time, thanks
Ehh, most scientist don't agree that the universe is infinite since space itself is expanding so it has to have a finite point to measure that. Obviously a theory, but usually the most agreed upon one.
Lol he literally explained how voyager one was 138x further away from us than the sun.. 30 seconds later.. wait, voyager is heading away from us.. I thought it was just orbiting around. LoL. Anyway, voyager was sent out to study our solar system and will keep going foe eternity
I'm more on the infinite part so there is an infinite mes replying to you but one sneezes here another there etc maybe one coughs and those all happen infinite times
Pausing repeatedly for extended discussions to yourself, or to pose inquiries to no one, really isn’t a reaction. It’s more of a commentary and introspection. I really just wanted to see a video reaction.
