Okay! Got it, Collinsmark. That is really helpful. Now I can wrap my noggin around it. Essentially, they'd need some uber telescopic technology to begin their mapping on the most distant regions first. Depending upon how sensitive their technology is (as well as filtering) may take a long time...

I understand (depending on the distance) we may have to shift to infrared frequencies to detect starlight. That's kinda besides the point. The response was a bit too simplified. Of course, what you would do is try to adjust your observations based on the new location. The question was could an...

Thought experiment I'm wondering if anyone has explored yet. Imagine by whatever means you like, that your spaceship plucks you out of our solar system and drops you at another random point in the observable universe. Due to light speed limitation, where ever you end up will be looking at our...

So because atmospheric pressure is the same on all sides it equalizes. If it was an astronaut's lab that was in a non-terrestrial ocean, the weight of the ocean wouldn't supplement gravity. It would just make it easier to keep it pressurized to Earth standard. If he exits the lab in a...

I was thinking about writing a novel where the setting takes place on a planet with a gravity similar to Mars or even the moon (Luna). My thought was that if the atmosphere was dense enough wouldn't that act in a similar fashion to increased gravity?

Ah! That's helpful too. Thanks Stevie.

Wouldn't be the same thing if you could manipulate what you wrote on the paper at either end. Change what is written on one page and have it intrinsically reflected in the other. But from 'DrChinese' response it is that very manipulation that would be a stumbling block.

Thank you. That answer was clear. So one limitation is the inability to manipulate particles into specific values. My understanding is that the original concept would overcome FTL communication because there is no information "traveling". They are two particles that intrinsically behave as...

With a modest understanding of 'spooky action at a distance', I've been informed that using entangled particles as a form of quantum bit system would not work for vast distances. It wouldn't be a viable option to communicate instantly with points like our moon, satellites orbiting Jupiter, or...

Another thorough, in depth response. Wonderful! I've got a good handle now. From the land of the Keck Observatory, mahalo nui loa!

I installed the app and WOW! Went through the PDF and figured the interface out. So much phenomenal information and useful references. Quite invaluable to any author writing a sci-fi series that wants a vital ring of authenticity. My story's setting would take place in one of those voids...

Thank you so much Bander!

NOW THAT IS WHAT I WAS LOOKING FOR! Thank you Bandersnatch. So the key factor is distance in determining viewable luminescence. Laniakea could not be seen by a human eye. And in the void of space we could only just make out a galaxy similar to Andromeda as long as we're within 15 Mly. That is...

I understand your reply Phyzguy. I just put the question there because there might be some point I might have overlooked with dark energy being a factor to the visual. I wasn't expecting it would be. Basically my question sort of revolves around this meme: If we're in a spaceship outside the...

Imagine you could jump in space/time from Earth to a point in deep intergalactic space smack dab in the middle of a void, those regions where dark energies are at their strongest. What would the view be like? Of course it's not total dark. You still have the light of distant galaxies. Would the...
