The other
day I made a good post I published in the (secret) blog for my two treasures very much about the way we measure distances
in our universe, I wanted to do it because I wanted to give to my princess a
way to understand how distances between planets or galaxies are so big that immeasurable,
therefore mankind has come up with a different method to use, that’s based on
the fact that the speed of light is the same no matter where you are in this
universe, so when someone tells you that the Andromeda galaxy is 2.2 million
tears far from earth/us, you are told not only the millions (billions) of miles that’s away from us but
how long of a time the light of that galaxy takes to arrive to us looking at it.
What made
me believe that this idea is worthwhile to discuss here in my main blog is
simply that if somebody was able to see earth from that far, what could be seen
are dinosaurs (at
least) walking on
earth.
I cannot
begin to describe how my imagination started to think to time-travel and to a
planet 10 light years away from earth, boy ho boy……….endless possibilities (of science fiction).
However,
what I want to talk about here today, in this new post is both the fact that no
alien can exist anywhere else in this universe and a bit about the
closest galaxy to ours (Milky Way) that
was named Andromeda.
I admit
that it makes me smile the thought that for hundreds of years a very large
number of telescopes pointed to this galaxy in search of alien civilizations……..of
course, what could be furthest and unreachable for not having some other civilization
flourishing there since billions of years…………
Given that
now (today) we concluded that in that galaxy
there might not exist anything else close to us, we are now looking at places
you may end up if conceivable to jump in one of the (plenty) black holes around our universe…….time
travel, parallel universes 11 dimension universes and on, and on, and on.…..
The crazier
(and
drunker) you are,
the more the alternative possibilities……
Any who, I
put – as usual – a couple of Youtubes and few links for you to explore and
enjoy (BUT
don’t
forget the donation to me, the creator of this!)
