... have you ever known how big they really are - and what are the biggest objects in space? Then have a look to the following short video. It amazed me a bit
You see them in game and in real life, but...

AAAAHHHHH red giant, super giant, hyper giant, mega giant, trita giant, supermegaultrahyperterragiga giantonic xD
Man today you posted 2 golden peices of videos. Haven't spent wathcing 20 mintues 1 same video(your other video) in a good while
-
WOW!
-
Holy crap - that's a big star. Big dog, hehe.
-
NO, YOU ARE NOT THE CENTER OF THE UNIVERSE !!
Stupid egoOP, have you used those sizes when making the Sol system ? Cus most planets and sun looked the same small floating stuff hehe
Still the "Pistol Star" is the most hot and powerful one... for the blue white color.... the hypergiant is just a quasar which maybe now it already exploded Remember we see them as they were millions or more years ago...
-
i am wondering if the center of the universe does actually exist, physically its at least hard to proof it
-
Every floating stuff is like shot from a point... they noticaed that from the frequency of the light.. which is lower, which means those celestial objects are getting distant from us. Well, where there's a big nothing, or a big black hole in middle of our own big bang.... now we can't know if it was the only one xD
-
I think I read somewhere that it's impossible to determine due to complexity of movement of galaxies, dark matter and/or dark energy interferences, gravity distortions by massive black holes and stuff like that... Maybe some day!
-
putting aside that there might be more than just one "universe" and ignoring the resulting theoretical "fact" that every definition of the word "universe" would be wrong then as the universe would be nothing but another "super structure" among many others i still would like to know if the center of the universe exists
scientists look into the sky... billions of years back in time to find the big bang
ok the theory is that the universe does expand and the oldest objects must be the ones with the largest distance to us.
BUT....since the universe theoretically does not only expand into one direction but into all directions we might look even too far into the universe up to the opposite border of it while we never notice the center
e.g. the universe is a disc with a center (thats just example to visualize it)... that center is 16billion light years away... and suddenly we see galaxies which are 20 billion light years ago -> we missed the spot
but why? because we can only observe light and the distance it takes to travel to us.
we can not travel back in time to see what really happenede.g. about 4 light years away there is a star
so we see what happened on that star 4 years ago but we dont see how this star was created
in the same way we might see galaxies which did exist 13billions years ago but we dont see anymore how they were created... we dont see how long they already did exist... its even possible that other galaxies did exist 50 billion years ago and we will never know about them as the light that they have emmited passed our region of the universe 30 billion years ago
the only way to "see" the big bang and the center of the universe (in my eyes) is when you are right at the border of the universe which is right now (or better to be said constantly) being hit by the light and radiation of the big bang -
You'll notice in-game, the large majority of the stars are dwarf-stars, as listed in their description I believe... I'm not even sure with OP using the mega-sized solar system like Sol or Sovetskaya, you could make a realistic hyper-giant star big enough as described in that video, either that or it would take up about 75% of the system I suspect, you'd barely be able to fly around it and still stay out of it's chromosphere!
What's interesting though about alot of those blue giant stars and possibly the more redder giant stars is that they have a high chance of going supernova near the end of their life instead of becoming even bigger!
-
stars only grow bigger during the end of their first phase ... usually when they run through the final process of possible natural fusion (upto the creation of iron atoms -> more is not possible as fusion of/to more complex elements is inefficient -> consumes way too much energy)
-
Still the sun will never arrive to teh other super giant red suns... as it doesn't have enough materials in it
It would be a nice small supernova at it's end...

you moron,.... oxymoron
No video not cool xD

Yep, as OP mentioned, a star at the end of it's life will either do one of two things depending on it's solar mass:
1.) If it's solar mass is 1.4 to 3 times that of our sun, it will eventually enter red giant stage, then either become a supernova with a resulting "left-over" neutron star from it's shrunken core, or possibly it's gravity will turn on itself and become a blackhole.
2. If it's solar mass is equal to or lesser than that of our sun, it will eventually expend it's hydrogen and enter red giant stage. Eventually the red giant sheds it's outer cores while the inner core shrinks creating a planetary nebula with the sun's "left-over" core becoming a white dwarf star and eventually over millenia, the white dwarf cools into a black dwarf star.

I tend to like the 2nd one more than the first one Although i believe i wont witness it myself^^

There can be no centre of the universe. It is too big, and has no structure. It is also constantly expanding, and as such, it is impossible to pinpoint a centre.
There is supposed to be a super black hole at the centre of all galaxies, and that is what starts the circular motion, which pulls everything into orbit, creating the swirling effect when looking at them.
As there is no definable shape of the galaxies, they cannot form a structure, ergo, the universe has no structure and cannot form a centre, which is combined with the constant expanding, and defies a centre.
Also, the centre super black hole at the centre of the galaxies counteract each other, and the gravitational pull is enough to keep things moving, except for when entropy occurs, for those whose belief lies in that area. -
Among the stronger achievements. Process the attention of 10 days watching black gap ... rofl.
In order to get time on Hubble astronomers are waiting for 2-3 yearsfor 2-3 hours of use.. Former director of Hubble's risked a lot and walked into historywith Deep Field.
Huh, now awaiting third Deep Field ... new cameras and new gyros were installed last year.For a deeper understanding:

QuotePLEASE READ: A parsec (symbol pc) is a unit of length used in
astronomy. The length of the parsec is based on the method of
trigonometric parallax, one of the oldest methods for measuring the
distances to stars.The name parsec stands for "parallax of one
second of arc", and one parsec is defined to be the distance from the
Earth to a star that has a parallax of 1 arcsecond. The actual length of
a parsec is approximately 3.262 light-years.
the Andromeda Galaxy is 0.77 Mpc away from the Earth.
the nearest large galaxy cluster, the Virgo Cluster, is about 18 Mpc away from the Earth.
the
galaxy RXJ1242-11, observed to have a supermassive black hole core
similar to the Milky Way's, is about 200 Mpc away from the Earth.
the particle horizon (the observable part of the universe) has a radius of about 14 Gpc.One
gigaparsec (Gpc) is one billion parsecs — one of the largest distance
measures commonly used. One gigaparsec is about 3.262 billion light-years. -
Well... It seam that size DOES matter...
