god i am soooo into this topic, i absolutely love every single aspect of space, especially the fact that we are never gonna find out the whole truth :) god i just cant get enough of it :D
here's a video that might help you a bit, i just find it so impressive :D
good thing about space is it never gets boring because you can always argue about new things because nobody will find out anyways, but the options are so complicated and complex themselves anyways that it doesnt matter who's right, because its just stunning...got a bit confused right here but well i am just soooo into these things....sometimes cant even sleep because of thinkin about all the stuff that could go on out there... :D
edit: oh and yh it looks absolutely amazing too xP
lol idiots!!!!!! everyone knows God only created us, the sun and the moon. and why would he create a spherical planet and get all caught up in this gravity shit when a flat surface would be easier. thus thats me proving the earth is flat.
There's a star called VY Canis Majoris, and the Earth is a pixel on your screen compared to this star. It also said it would take 1100 years travelling in a jet going at 900mph to circle the star once, can't even begin to imagine it tbh, fucking mentalllll.
If anyone in the UK/Ireland missed the first episode of Brian Cox's Wonders of the Universe as well as the 700th episode of the sky at night on sunday then they're on BBC iPlayer - highly recommended.
It's looking like it's going to be a clear night here, so will probably do some stargazing in the back garden later with my 100 x 25 binoculars. ;DDDDDDD
Not so much of a space reply, but dunno how many of you have seen documentaries with michio kaku. Youtube his name, has a lot of interesting topics regarding physics (the theoretical part of physics) i.e. time travel, invisibility, teleportation etc.
Not now no, I'm gonna be doing Computer Security & Forensics hopefully but if I graduate from that then when I'm older I might go back to uni and do Astronomy or Astrophysics.
Astrophysics would be fucking very hard though, you need to be a very bright spark, if not then basically every second your nose would be in the book. ;P
what's interesting about space is how gravity effects time, and with the universe being vast and "containing" large and tiny objects we have lots of strengths of gravity,
which in turn means we can experience time differently when at different places in the universe,
for example if you circled a super-massive black hole for a year, more time would have passed on earth than for you.
making time travel into the future a possibility all-be-it and unlikely one
"Gravitational time dilation is the effect of time passing at different rates in regions of different gravitational potential; the lower the gravitational potential, the more slowly time passes. Albert Einstein originally predicted this effect in his theory of relativity and it has since been confirmed by tests of general relativity."
But the example i give above exploits both gravity which already effects time but also using the gravitational pull to orbit the black hole at incredible speed meaning time is also passing slower
in theory is anyone was stupid enough to attempt to do this and was able to travel to a black hole and then manage to go into orbit around it without getting sucked into it, they could advance as far into the future as they wanted to,
Probably the most amazing video I've ever seen. Anyone reading this, this video is honestly the most thought provoking, inspiring and influential thing to happen to me ever.
Space and the universe have always fascinated me tbh. It's mostly the size of the stars that have been discovered that interests me, ones that are millions and millions of times bigger than our planet, kind of hard to comprehend.
Yes when you're doing it at home, but School find ways of making it boring , seriously.
If I'm trying to learn about something for school I just can't, but if it's something I'm really interested in I can just go away and be left to my own devices and learn so much about that subject it's unreal, more than school would ever learn me.
Technically, you can 'see' it. But without a proper telescope, it'll just be a smear of light basically. Not really exciting to anyone unless they appreciate the fact that it's an entire galaxy.
@ Knaller, if you can find the Constellation Cassiopeia, it's like a W, or an M on its side. If you keep looking to the left, and below and to the right of the Constellation Perseus is Andromeda (in the Constellation Andromeda).
And csmz is right, it would appear as a sort of smudge of light, to both the naked eye, or a normal pair of binoculars/telescope.
Most of the pictures you see of galaxies like this, or nebulae are because telescopes have been pointed at them for a sustained period of time in order to suck in more light, each at different colours of the spectrum, and then they're layered over each other in photoshop basically, to produce such a colorful picture like this. :D
Also the sky needs to be pitch black, you would need to go somewhere rural to see it. Same with the Triangulum galaxy in the Constellation Triangulum, which is quite nearby in the sky - it's arguably the furthest thing which can be seen with the naked eye (3 million light years away), and is the third largest galaxy in our local group after Andromeda and our Milky Way.

IC 1101 the biggest galaxy we've found in the universe! it lives 1 billion light years away (at z = 0.0767) in the massive abell 2029 galaxy cluster. the unromantic name comes from the index catalogue which was created at the end of the 19th century.
IC 1101 floats with a girth of 6 million light years, making it 60 times larger than our milky way with its mere 100,000 light year diameter. how many stars does the most massive elliptical galaxy contain? 100,000,000,000,000 = 100 trillion = 10^14 stars.
too far away to get a decent pic but i think the text speaks for itself

Already got a pair of 100 x 25 binocs for now though. ;DDDDDDD

Bright spark? Reppin' the 5W energy savers here ://

2 things are infinite : the universe & the human stupidity. But for the universe, i'm not sure

I thought gravity only bends space.
But the example i give above exploits both gravity which already effects time but also using the gravitational pull to orbit the black hole at incredible speed meaning time is also passing slower
in theory is anyone was stupid enough to attempt to do this and was able to travel to a black hole and then manage to go into orbit around it without getting sucked into it, they could advance as far into the future as they wanted to,
also bends rays of light and like pulls spacetime

As for the gravitational potentials, they're explained with E=mgh and the kinetic one with E=mv^2.
The lower the potential, the higher is the kinetic gravitational pull, so the higher should be speed therefore the time passes slower, am I right or?
cos of the equivalence principle, the grav force on a massive body (locally), is "the same" as the force experienced in a non inertial system
im not a huge expert though, don't have lectures about this stuff
einstein:
(Inertial mass) (Acceleration) = (Intensity of the gravitational field) (Gravitational mass).

It's weird because it's supposed to be boring.
I can happily come home from school and want to read about things related to it.

Love to discuss things like this.
:}
but define easy to find, can u just see it? :D or u need some amateur telescope or something atleast?

it's actually crazy that you can see something with the naked eye that is so far away it takes light 3 million years to get here fml
