sonofthunder:

just one galaxy contains hundreds of billions (about 200 billion thereabout) of stars, and same value (approximately not exact) goes for galaxies... so you have trillions if not zillions of stars.
(hope I ain't giving you a headache?)

gimmehear:
it a random oscillatory process

johnydon22:
Naaah the sun is just too hot i mean Millions of ° hot..

Most stars are extremely hot ..

luvmijeje:


My goodness! To imagine the stars are almost the same size or bigger than our own sun.

sonofthunder:

our is not that big compared to others... trying to comprehend the universe is try to run 'mad'...Lol.
if you really interested in science try and learn about subatomic particles and discoveries in that area. there's not been many new discoveries with the big objects but the 'small things' are getting really interesting.

[b][size=20]10.[/size]Revolution

This is for the ones that think the sun is stationary... Well sorry but it is far from it..

Moons revolve around planets
Planets around stars
Stars around center of a galaxy
the galaxies orbit some bigger galaxies or in a dance of gravitational beat.

all matter in the universe goes on a jolly ride with the expansion of space time..

Our universe is constantly in motion.... Nothing is stagnant or stationary, there is always motion..

The sun is located in the milky way galaxy, in the Orion's arm of the galaxy which is one of the arms of the spiral galaxy..

Like every spiral galaxy, all the arms are swirling around the center of the galaxy.. Stars with planets, clouds and dust.

So our sun alongside with all the solar system is in orbit around the milky way galaxy..

the milky way galaxy is 100,000light years in diameter, the sun (solar system) is about 27,000 light years away from the galactic center.

so it takes about ±250 million years for the sun to complete one resolution around the galactic center.

So yes the sun is not stationary... Picture below: The single dot points where the sun and entire planetary system is in the whole milky way galaxy[/b]

[b] [size=20]3.[/size] The sun is 4.6 billion years old


Yeah judging from life spans of Stars, we could say our sun is still a middle aged vibrant young lady..

Approximately 4.6 billion years old it will take up to about 5billion years old for it to exhaust it's hydrogen supply and therefore begin it's dying process.

Our sun as an average star will die in a slow and very treacherous way.. Now it has an abundant supply of hydrogen to maintain nuclear fusion in it's core which provides all the energy.

Hydrogen+hydrogen---> helium.

when this hydrogen supply runs out, it will start fusing helium atom to make heavier elements.

Helium + Helium -----> Iron, oxygen, Carbon.

at this stage it turns into what we know as a Red giant.. Gets cooler but larger and appear bright yellowish-red.

And that stage Mercury and Venus are goners and the earth will be as close to the sun as mercury..

then slowly and painfully shed off it's materials into outer space and collapse into a white dwarf about the size of earth ...

for more stars more massive than the sun, their death comes in a more rather violent manner. a stupendous explosion called supernova..

so any living thing on earth by that time is roasted!!!

Naaah don't worry, 5billion years is enough time to get dead. so it's not happening any time soon..

The Qur'an has mentioned this, several 100 years ago. Suratul Yasin(Q. 36 vs 38). Look it up

[size=20]7.[/size]Dark spots

There are temporal phenomenon that appear to be very dark on the sun's photosphere in contrast to every other part of the sun. .

These dark spots are called Sun Spots.

And are caused by concentration of magnetic flux on that given region giving rise to decrease in temperature from every other point and so appears dark.

johnydon22:
Asin eeeeehn e tire me... The god damn book was thinking the sun freaking orbited the earth and mentioned an orbit and dudes are trying to incorporate that crap to recent findings.

I wonder if the bible and Quran thumping religionists had a more impressive work like that of ancient Sumerian texts that accurately measured the orbit of Jupiter, we would have been hearing that shiit everyday.

like "the bible/quran measured the orbit of the jupiter 3500BC ago .. God is great" but alas they are all freaking out over this punny speculations.

Imagine if the bible or quran had an impressive scientific fact (measuring jupiters orbit) like a more ancient text (sumerian text) did

luvmijeje:


Anything is possible in science. If we can land on the moon, we should be able to conquer the sun.

afoobabs:
@ op This is really informative pls when ar u goin to come up with something abt moon.

And sir if sun powers the planet what is other bigger star like canis majoris powering.

And what abt the thing that look like falling star that we use to see when we were young ar they really stars

kevoh:

Years ago, it was near improbable for humans to fly... Science never gives up!

Hysmady:
Good.Exactly no one knows and what if there are many other universe outside this universe we are in...just curious

AgentOfAllah:

At some point, earth was the centre of the universe, then we found we're just one of many planets orbiting the Sun. Now we know we're just one of many stellar systems orbiting around the centre of the milky way. We also now know that the milky way is one of many galaxies in a local cluster of galaxies, so it is not inconceivable that our universe may well be one from a cluster of parallel universes...although, this veers into the realm of speculation.

Tellemall:



True. But it is easier to fly than change the biosphere and crust of an entire planet. We may have something like greenhouses out there, but not such drastic things as terraforming.

Terraforming is eons away. Pun intended.

johnydon22:
You will see one about the moon soon

Some stars host planets while some don't... I doubt if Canis Majoris hosts any planet MAY have some smaller star(s) orbiting it though..
Its a meteor... a small astroid debris that enters our atmosphere at incredible speed and lights up .. there are not stars

charlesm91:
just to satisfy my curiosity and I'm not science oriented by the way; if there's the speed of light and it's measurable, what then is the speed of darkness? Might sound dumb but u know, just a thought.
