Mmmh I didn't you didn't get fully what I wrote. Please let me clarify a bit and provide more details, so that my points will be easier to understand. If not, feel free to come back to me.
Science talks about the death of stars. A star's life span is related to its fuel. That is, I have called those stars that have not yet run out of fuel as living stars.
This is correct. However, this is not at all my point. Let me clarify.
The moment at which a star emits its light and the moment at which we see this light on Earth may be two very different moments. Due to the finiteness of the speed of light, light takes some time to get to us. For stars lying at millions of light-years from us, millions of years have passed between light emission and observation. During this amount of time, it is not unlikely the star has died. Therefore, all the stars that we see are definitely not all living stars.
At the center of our galaxy lies a black hole. Our solar system is moving in that direction.Without the black hole at the center of our galaxy, would it be good for life if we were isolated in the universe? I think that just as our solar system created the perfect environment for life on Earth.
What you answered is different from what is written in your blog. The fact that life was possible on Earth is due to a lot of different causes (I am not even sure we know them all), the configuration of the planet within the solar system and the properties of the Sun being two of them.
However, the fact that our solar system moves towards the black hole at the centre of the Milky Way does not imply anything. We have the counterexample of all other planets of the solar system, that are similarly affected by this black hole whereas there is no life on them.
I also think that this galaxy is a system that sustains our solar system. We cannot deny that this is a part of the Milky Way Galaxy.
Of course he solar system is part of the Milky Way. However, how does it impact the fact that life appeared on our planet. Life appeared mostly due to local conditions than global ones at the galactic level. Otherwise, we should be able to observe life everywhere, shouldn't we?
Yes, I understand ,Your powers of observation are great. I have benefited from discussing science with you. Hope to see you in the next posts. Hope to be able to gain more knowledge from you. This is stemsocial. Community for discussing science
Thanks :)
