Question
1. Is our Solar System expanding as a result of the expansion of the Universe, or not? Explain your answer. 2. Why can we not use 14C to find the age of most of the rocks on Earth? 3. We learned from the Big Bang theory that the Universe is a little more than 3 times older than the Earth and the Sun. We also learned that the Sun has enough hydrogen in its core that it can shine for about 9 billion years before it runs out of energy. So we are about half way through. The Milky Way, like all galaxies started forming soon after the Big Bang Given this, consider the following statement "It is pretty much certain that there are stars like the Sun but perhaps one or two billion years older than the Sun. If those stars have planets too, life would have had 1 to 2 billion years more time to evolve, so such planets likely would have far more advanced life than we do." Describe if this statement makes sense to you or if you find a reason why we might not be so certain about the point that it makesExplanation / Answer
1. No, the solar system is not expanding due to expansion of the universe. Let me explain. While the facts demonstrate that the universe is extending, understand that it is space itself that is growing, not the 'stuff' in space. It's not the case that sub-atomic particles are becoming greater or something to that effect.
Independent from anyone else expansion would prompt to seperation of matter, however expansion of space isn't the main character in this circumstance. Gravity is an all inclusive, long range force, that, up to a specific separation will be solid enough to counter the impacts of development. Another method for saying this is gravitationally bound structures, similar to World bunches, cosmic systems, and planetary frameworks are not affected by the development of room, since gravity will pull questions back to their unique separations.
So the solar system won't expand and be pulled separated. Should the rate of expansion radically increment then the appropriate response may be unique, causing structures that are presently gravitationally bound to wind up unbound. A sufficiently high expansion rate may have the capacity to destroy our solar planetary system.
2. Carbon dating 14C cannot be used to date rocks on Earth. It can only be used to date things that were alive and absorbing carbon from the atmosphere fairly recently.
One can't predict when any single C-14 atom will decay, it is probabilistic, so we can only make predictions about what a large collection of C-14 is going to do and the term usually used is half-life. C-14 has a half-life of around 5730 years which means if we started off with a 1 g lump of C-14, in 5730 years, that lump would contain only 0.5 g of C-14, with the rest of the lump having decayed. And this process goes on untill C-14 becomes negligible.
But importantly animals and plants consume carbon so it C-14 is useful for arccheological findings for specific rocks where life and age of life existence can be tranced. Thus C-14 is used only in 'certain' types of rocks and not in most of the rocks on earth.
3. We are definitely not certain about the statement mentioned about life being in advanced stage in other planatary bodies in old stars and their systems.
The tale of how the Universe came to be how it is today, from the Big Bang to the huge drained of space covered with groups, worlds, stars, planets, and life, is the one story we as a whole share for all intents and purpose. From our point of view here on Earth, it took around 2/3rds of our mutual cosmic history before the Sun and Earth were even made. However life showed up on our reality as far back as we're ready to quantify: maybe as much as 4.4 billion years prior. It makes one think about whether life in the Universe originated before our planet, and, so far as that is concerned, how far back life could go?
Sadly,carbon, the fourth most common element in the Universe, which we need for dating and finding potential age of matter, is actually the very last ingredient to come about in the abundance in Universe, we need. Rocky planets, at least in some locations, come about much earlier than life can, might be just half a billion years after the Big Bang, or perhaps even sooner. Once we have carbon, however, 1-to-1.5 billion years after the Big Bang, all the steps we need to take to produce organic molecules and the first steps towards life are inevitable. Whatever life processes took place to lead to humanity's existence, as best as we understand them, could have begun when the Universe was only one-tenth the age it is now. But all these does not support the view of advanced life form in other planets. An absolute uncertainity lies in the statement itself.
