@@hownottogame8423 No it didn't. Let me ask you this, knowing that rubidium-87 have life time of 48,8x10^9 years tell me how to calculate age of Sun

two major problems (at least). 1. the assumption that everything in the solar system formed at the same time. 1.5. the assumption that the material that they date is from our solar system. 2. the assumption that the energy from the sun we get on earth is equal all around the sun. 2.5 do they calculate that the energy we get on earth is all of it or do they try to include what would be going off in the other directions as well?

1. It's a good assumptions, and comparative studies were done on different materials to approximate the age of the sun. it's an almost impossible scenario for a planet to be older than the star it's orbiting. 1.5 Also a good assumption. Especially because of our better understanding of stellar formation and nucleosynthesis. 2. That's a matter of principal. If the sun had a preferential direction, it would behave very differently. 2.5 You just measure the ratio (the flux of energy emission). With this ratio you can estimate the amount of energy that leaves the sun.

Abdel Armstr 1. Just the opposite as a planet would take less time to form than a sun, there is no reason to believe a planet couldn't form before a star let alone all the non planetary material. 1.5 also a bad assumption. Jupiter catches all sorts of debris coming from outside the solar system, it's unreasonable to assume it catches everything. 2. The sun "prefers" different directions all the time they're called solar flares, and naturally a solar flare projects more energy than the rest of the sun, and since we only see half the sun ( maybe less) it's a bad assumption to think we can estimate all the energy leaving the sun. 2.5. I'll take that as a yes they do include an estimate of energy from every direction.

1. No, not the opposite. First, if a planet evolves in a lesser time, then that means its lifespan doesn't not exceed the Sun's. So I don't know how this suggests that a planet is older than the star. I'm not saying that it's impossible, I'm saying that it's extremely rare for a planet to be orbiting a star it didn't emerge from. Why? for multiple reasons. Planets contain heavier elements like iron. The only way that for a planet to exist is by nucleosynthesis of heavier elements from the explosion of a star (which is proven for our case, considering that the sun is a second generation star). The debris of these heavier elements coalesces to form planets within the gravitational field of the resulting stellar object. It's a very delicate scenario for a planet to leave a star, be untouched, and go orbit another star. Today, we also have nucleocosmochronology which is a great tool since we know so much about the sun's elements, and it confirms the age of the sun. 1.5 The extreme majority of the debris that Jupiter catches comes from the asteroid belt, which is within the solar system. I think you underestimate the huge size of the solar system compared to outside debris, which usually goes straight to the sun if ever caught. 2. Surely the flux of emitted energy from the sun's surface is heterogeneous, but its flares are local turbulence. The sun's behavior, on a macroscopic level, is isotropic, meaning that it behaves the same in the three directions. Please note that solar flares is not the same as preferential directions. Plus we see the whole sun's surface because its rotation is not synchronized with the earth's rotation the way the moon is. Within 24.5 days we can see the whole surface. 2.5 Yes all of the sun's emission is taken into account. I think that even today, calculations include small corrections of any particular flux that is not average. I'm not sure, but I think so because the age is given with very good accuracy (the margin of error is 0.9%)

@abdelarmstr5173

I think I'm wrong about 2 when I said "the sun's behavior is isotropic." Probably the sun's rotation affects is emission flux. But even in this case, scientists can work out the disproportionate emission by computer models knowing simply the sun's rotation parameters.

1.and1.5: it's not the life span that's important it's the starting date, the planet may go cold before the sun or after the sun depending on when it was formed. " resulting stellar object", another assumption, the theory goes that there was a proto star before our current star then it went supernova and excreted all this iron. including all the iron that makes up the suns core so the sun would have to reform, your statement implies it's already there fully formed. when a star goes supernova the planets orbiting it go elsewhere probably in pieces but for all you know the astroid belt could have come from another solar system that blew up already. 2. how exactly can you tell how fast the sun is rotating if even at all, it's a lump of hot gas with no distinguishable features like the moon has? However that wasn't really my point anyway, my point was there could be numerous solar flares of varying sizes happening on the side of the sun we can't see so theres no way for us to accurately measure the energy produced by them. there are more than 3 directions.

The Sun Is Over 4M Years Old

Apparently e=mc2 is the equation for everything...

Wouldn’t Rubidium decay be different because of our atmosphere ??? & if so how would we know the decay rate in space ???

@realdragon

Ай бұрын

Decay rate doesn't change

So basically they know how old the star is based on whether or not some of its energy reached the earth that they were focusing on through some instrument. And then calculating its distance away for how long it would've taken to get here, and then its mass by it's gravitational influence through newton's law.

The presentation of your explanation was great, but when you arrived at the conclusion I still didn't feel like you answered the main question. You were able to give an idea of how much time seems to be left until the sun burns out. However, that is not an explanation for how much time the sun lived before the moment of testing. I find your explanation to be more of a circular argument that assumes it is the age you stated, just because that is the initial assumption you had when you first started to explain. I'm still left asking the question of why you think it's that specific age... Are you just basing it off assumptions you are making from observing other seemingly similar stars? Assumptions. Assumptions. Assumptions. I'd love to see your revised version of this--following a bit more investigative work.

Very very helpful video, Though not in the way I expected it. I wanted to determine the age of our nearest star Proxima Centauri so I searched on Google and I saw this video and I watched it but I didn't have and want a meteorite crashing down on my head and didn't know all about this Rubidium stuff. It though helped me to determine how much hydrogen or son generates per hour and how much is changed into energy, that to per hour. I think the number would be half of the number of atoms in the universe do I don't know the number of atoms in the universe but the number is mind-bogglingly huge. Anyway, thanks for recommending to have a meteoroite crashing down on my back garden, I will try that very soon.

The entire Solar System was formed from an enormous rotating collection of materials, mostly hydrogen, but also other heavier elements as well. (Hydrogen and some helium were formed in the aftermath of the Big Bang itself - actually about 400,000 years after the Big Bang - while even heavier elements were formed inside previous stars, which have since exploded, releasing their heavier elements.) Due to the universal attraction of all matter to all other matter, this cloud of materials began to coalesce into the Sun and planets. Anyway, due to their common origin in this cloud of materials, this is how we know that the Sun and other constituents of the Solar System are all roughly the same age. I hope that helps.

@@radupatron6137 To refute a statement by saying "it is just a theory," does nothing to actually refute it. Some people hold the "theory" that some god created the entire universe in six days, based upon the "theory" that some collection of "approved" writings, produced during primitive and superstitious times, were not merely the product of the mystical and superstitious people who lived in those times, but were actually the result of "divine inspiration." Now, while one could debate the faults or merits of this or any other "theory," based upon actual logic and evidence, to merely state that something is a "theory" does nothing at all to assess the logic and evidence behind it. Furthermore, to believe in a "theory" in the absence of logic and evidence, or despite strong contradictory logic and evidence, is really not to have a well-formulated theory at all, but something less..."faith," i.e., beliefs accepted not based upon logic or evidence - or even despite contradictory logic and evidence. The short comment I made above, is just that, a short comment. It was an integration and condensed statement of our very best understandings regarding the formation of the sun and planets (our solar system) based upon countless observations and calculations, all of which support (and none of which contradict) the points I made regarding the common origin and age of the solar system and its constituent parts, namely the sun and planets. This theory is not just an "opinion," or merely something accepted on "faith." It is supported by our knowledge of such things as particle physics, astrodynamics, the observations of countless other solar systems throughout the universe, at every stage along in their life-cycle, and much more, too much to mention here. If you have anything of substance to add, other than the rather empty fact that this is a "theory," along with your misunderstanding that scientific theories of this type are not based in the most solid of facts and observations, that would be great, and might even lead to a productive valuable exchange. As it is, however, your statement IS empty, does nothing to discredit the theory or the evidence behind it, and instead does more to point out your own lack of knowledge on the topic than anything else.

This is a bunch of BS the Sun is not 93 million miles away it is right over your head where you can see it. You can see clouds in front or behind the Sun, is the clouds in outer space too? Does it rain from outer space? No it don't. You cannot create or destroy energy the Sun is pure energy it would never burn out. There's no such thing as gravity that's why helium goes up cuz it's lighter than oxygen. The Sun is not above Earth it is inside of Earth that's why I higher you go the colder it gets🤔
