[QUOTE=bradleigh;50808242]when i see shit like this, all i can think of is endless possibility really makes it hard to believe that there isn't something else out there, also looking at the stars, wondering if we exist as well[/QUOTE] there's probably things almost exactly like humans out there depending on how big the universe really is there could even be an identical earth
[QUOTE=DOG-GY;50808266]there's probably things almost exactly like humans out there depending on how big the universe really is there could even be an identical earth[/QUOTE] Eugh, i dont want another trump on earth 2
[QUOTE=DOG-GY;50808266]there's probably things almost exactly like humans out there depending on how big the universe really is there could even be an identical earth[/QUOTE] FWIW, we've mapped about 100 million galaxies of the 100-200 billion in the observable universe or about 0.01%, and the entire universe is thought to be 250 times larger than that.
[QUOTE=SebiWarrior;50808277]Eugh, i dont want another trump on earth 2[/QUOTE] there might even be a trumpless earth, but we are not so lucky
[QUOTE=Smug Bastard;50808173]Well, that's only slightly condescending. I, for one, was under the impression that gravitational lensing of light had not yet been observed, so when I saw that we had pictures of it I was delighted. I think most around here were probably under the same impression. Most of us aren't as keen of followers of space-related news as you might be, so I'd reckon "Its like you've never seen a picture of space" is a bit harsh. I still have to thank you for the awesome pictures, though.[/QUOTE] In fact gravitational lensing was one of the first tests to confirm general relativity. Eddington observed it in 1919, by measuring the deflection of light from stars behind the sun during a solar eclipse.
I have always liked images where galaxies line the field like stars. When you see images focused on stars in our own galaxy you realize that if you look a little deeper it is apparent that our galaxy is one among billions. Its also really amazing that our instruments here on earth are so extraordinarily sensitive that we can take measurements of objects in other galaxies. Astronomical instruments are wonderful pieces of machinery.
This is absolutely [I]astounding...[/I] Wow. This is an image of [I]time[/I] being fucking [I]warped.[/I] This is some next level shit right here. Fucks with my head on the same level as the Multiverse Theory. [editline]31st July 2016[/editline] Now, [I]that[/I] is some shit.
[QUOTE=MendozaMan;50802574]And of fucking course einstein was right all along again Its funny how it's still called a theory at this point[/QUOTE] Didn't the swiss figure out some quantum mechanics shit where they can entangle two photons and what happens to one instantly happens to the other, regardless of distance? Wouldn't this prove Einstein's theory wrong
[QUOTE=TheTalon;50808629]Didn't the swiss figure out some quantum mechanics shit where they can entangle two photons and what happens to one instantly happens to the other, regardless of distance? Wouldn't this prove Einstein's theory wrong[/QUOTE] It's not in conflict with relativity because no information can be sent via entanglement faster than light.
[QUOTE=SIRIUS;50803528]All gravity bends space-time[/QUOTE] i guess it was dumb to say that on my part, but then science was my lowest class grade in school
[QUOTE=SIRIUS;50803528]All gravity bends space-time[/QUOTE] To be more pendantic, mass curves space-time and the curvature of space-time manifests itself as gravity. I think. :v:
I can't wait to see what pictures the James Webb telescope will produce.
I'm not happy until I get a [URL="https://upload.wikimedia.org/wikipedia/commons/5/5e/M104_ngc4594_sombrero_galaxy_hi-res.jpg"]SPACE[/URL] [URL="http://photojournal.jpl.nasa.gov/jpeg/PIA15254.jpg"]sized[/URL] [URL="https://upload.wikimedia.org/wikipedia/commons/2/2a/GLIMPSE-MIPSGAL_Milky_Way_2.jpg"]image[/URL]
[QUOTE=thrawn2787;50808139][t]https://cdn.spacetelescope.org/archives/images/wallpaper5/potw1506a.jpg[/t][/QUOTE] gravitational lensing is cool. the galaxy is smiling at you
Oh boy, can't wait for glasses to have no actual glass in them and rather have localized bent gravity field that adjusts how light comes through it. [sp]Then it breaks and rips your fucking eyes right out of your sockets[/sp] Jokes aside, it's extremely awesome to see something I knew for a long time in such an interesting example.
[QUOTE=Smug Bastard;50809123]To be more pendantic, mass curves space-time and the curvature of space-time manifests itself as gravity. I think. :v:[/QUOTE] To be even more pedantic, mass-energy curves space time. Even massless energetic things like photons can create gravity.
[QUOTE=JohnnyMo1;50810644]To be even more pedantic, mass-energy curves space time. Even massless energetic things like photons can create gravity.[/QUOTE] To be even mooore pedantic, AFAIK gravity can't actually be created, no? [editline]1st August 2016[/editline] Despite a common answer being no, if the conditions were right, would a photon be able to orbit a singularity?
[QUOTE=Map in a box;50810944]To be even mooore pedantic, AFAIK gravity can't actually be created, no?[/QUOTE] That's pretty pedantic. But yes. You are technically correct (the best kind of correct). That's why when people ask things like "What would happen if the sun just disappeared right now? Would we know instantly?" the question is really unanswerable. The question breaks the rules of general relativity in the setup. [QUOTE=Map in a box;50810944]Despite a common answer being no, if the conditions were right, would a photon be able to orbit a singularity?[/QUOTE] Sure.

[editline]1st August 2016[/editline] That being said its quite a large thing so its not exactly easy to test to find out

[editline]1st August 2016[/editline] That being said its quite a large thing so its not exactly easy to test to find out[/QUOTE] The point I was making is that you can't even ask the question. Mass-energy can't disappear like that, general relativity forbids it, so it makes no sense to ask what a theory says when you purposely break it.

[editline]1st August 2016[/editline] What-if questions usually break science for the actual what-if part to see what would happen
[QUOTE=Map in a box;50811344]What-if questions usually break science for the actual what-if part to see what would happen[/QUOTE] Not really. You can ask all sorts of what-if questions like "what if we found matter with negative mass" and try to figure out what it means based on currently understood theories, but general relativity actually contains a statement that says "this never happens."
but johnny what if star trek [I]is real[/I]

[QUOTE=JohnnyMo1;50808472]In fact gravitational lensing was one of the first tests to confirm general relativity. Eddington observed it in 1919, by measuring the deflection of light from stars behind the sun during a solar eclipse.[/QUOTE] And now we use it to measure the mass of supermassive clusters and other objects. Went to a talk on this a while ago, its pretty interesting how they extract data from something like gravitational lensing.
