What is your favourite thing about outer space. Why is it interesting and what is the meaning of it?
This topic is locked from further discussion.
what I never understood is how physicists can demonstrate the bending of space and worm holes with rolled up 2d planes when space is 3d. Like a black hole for example: it's always depicted as a plane with a funnel.The fact that it is constructed of spacetime, which can be "bent" and manipulated. I find that interesting because it's insane to think what goes on outside of spacetime.

Space is beyond us as humans, sure we've travelled into space but i don't think we'll ever discover whats really out there in terms of alien life forms or venture into other solar systems/galaxies.
Its a place we as individuals will never go, thats why i find it fascinating.
The name says it all. Space. I can't wrap my head around the scope of it. I can look out into space and try to understand that those tiny, bright little specs are actually massive spheres of plasma farther away than I could possibly imagine, and yet I can't. It just doesn't register. Staring off into space is probably the greatest natural psychedelic.

I agree, what really bothers me is that the light coming from those stars takes millions of years to reach Earth.
So what we're seeing of them now is the past, if i'm correct.

They're just trying to make it simpler (that and it's not possible to show what it would actually look like, as far as I know). It is a very hard concept to imagine, warping the space around you in three dimensions.

The most amazing thing about outer space is how amazed we are by outer space. I'm more concerned with matters down here than up there.Theokhoth

Also, ever notice that everything that we know is just spheres orbiting spheres? atoms, planets/moons, stars/planets, galaxies/stars...Perd1t1on
Yes, and yet they have a different set of phsyics (atoms, I mean), which makes me wonder if our universe is just part of some other structur that is the building block of whatever is outside our universe, which is part of the whatever makes up whatever is outside of that, and so on, all with different sets of physics.

whoa! it's like i just watched the ending of MiB. now i want to play with my marbles.

Like a black hole for example: it's always depicted as a plane with a funnel.Perd1t1onGreat question - the images you see of "wormholes" and black holes are just constructs (think of them as a "scientist's rendition." They have never been directly observed.
As for the bending of space, that was predicted in the early 1900s (I believe sometime in the late '20s to '30s). It occurs when light from a distant bright source, "bends" around a massive object. The space around a massive object literally distorts, changing the path that a light wave travels and ultimately the time it takes the light to reach an observer. The effect is called, "gravitational lensing" in fact. You can think of the effect as being similar to that which occurs when light passes through an optical lens, but the main difference is that, unlike in "regular optics," the distortion or bending occurs closest to the gravitational lens, rather than further away.
Movies and shows that glamorize it by zipping around in fancy ships while discussing fictional science and visiting made up planets and galaxies full of ridiculous life forms and societies. It's amazing how they go placs to explore, toseek new things. To go places no one has ever gone before nor will ever go because they are all made up.
The fact that I would bepooping in my pantsif I were to go into outer space is the least amazing aspect of outer space.

Not all planets are perfect spheres though! The Earth is a bit oblate. Some atomic nuclei also lack spherical symmetry too; they are called quadrupolar nuclei. Also, electrons do not orbit the nucleus - that is a common misconception. Electrons exist in different energy levels within an atom. These electrons in different energy levels have different angular momentum. The problem is, people think of something rotating and spinning when they think of angular momentum. Angular momentum is an intrinsic, quantum mechanical property; it's very hard to visualize. An electron is a charged particle. If it revolves around a nucleus, that would mean it has an angular acceleration. Accelerating charged particles emit radiation, so if the electrons were truly orbiting a nucleus, they would eventually spiral down into it because the emitted radiation would take away some of the energy of the particle. Physicists and Chemists think in terms of atomic or molecular orbitals, which are regions in space where they probability of finding an electron is high. You can think of it as an "electron cloud" over a nucleus.

Yes, but it seems like the 'goal object' is the sphere of all things, and the goal of all things is to 'join the largest sphere'. I wonder if there is a situation where spheres would not be the perfect shapes.[QUOTE="zmbi_gmr"]

Did you just type that off the top of your head, or is that something you wrote earlier? Either way:Yes, but it seems like the 'goal object' is the sphere of all things, and the goal of all things is to 'join the largest sphere'. I wonder if there is a situation where spheres would not be the perfect shapes.Perd1t1onI think that you are reading too much intent as to the consequence of the unidirectional attractive force of gravity; I can think of numerous instances (a number of biologically significant molecules come to mind) where a spherical shape would be disastrous.

People call such bodies spheres for the sake of expediency. You'd be hard pressed to find a perfect sphere. Just sayin'...

I heart you Theo. Mongo too.
I remember when I was a kid in grade school the astronautsmade it seem so awesome, but onceI found out they went in their pants Iwas like"WOAH! That is not awesome, that is way below awesome, it's closer to abysmal." So outer space makes me think ofCarrying around a sack full of my waste like it'sfanny pack full of treasures.
I like how space is too big and complicated for our little minds to comprehend. There's what we dont know and what we think we know.
