Reply to comment by Dave-C in We can't see on the other side of the Sun. Have we ever used satellites to see the other side? by Dave-C
Oh yeah. Something could hide directly on the opposite side of the sun from us, but probably not from a spacecraft in a trailing earth orbit, especially if it trailed further than like one earth radius

I think op means the area of space directly behind the sun. The answer is yes. We rotate around the universe on several axis. The parts that we can’t see are based on the north or the south hemisphere but if you had the ability to go anywhere on our planet, you could see in all directions around the universe, and during certain times of the day and certain times of the year someone able to go to anywhere on our planet would be able to theoretically see in any direction into the universe. I hope that helps. It was hard for me to explain without drawing pictures.

Not to pick on you, but technically you get time dilation any time you speed up relative to what your speed was previous. I think people have been able to prove this experiment with long-haul commercial flights and fantastically accurate clocks.

Off topic but I had a black cat named A*. Called him Star. My dad is a nerd who taught me to be a nerd.

This is going to be my last response to you because I am positive that you’re trolling us, trying to get karma so you can post spam in other subs that have rules about new accounts posting.
That said but the only reason anyone would do this would be because they wanted themselves and all of their descendants to live on that asteroid forever. You would need insane technology just to get to the interstellar object, let alone land and mine it. For sure it is not anything that would happen in either of our lifetimes. Fairs seas, my little troll.

At this point most of us have realized that either you’re trolling us or you’re too simpleminded to grasp the basic physics of this.

My man should just hop on Eros, maybe he can talk the Ring entities into going interstellar instead of to Venus

Why wouldn’t you just stay in the ship that you built that already had enough Delta V to escape the system? I see what you’re getting at but why would you want to do it? The thing would be moving so fast you would spend so much energy trying to catch up to it then you’d have the complication of trying to land on it and hope that it fits your needs. All those pictures you saw of those previous interstellar objects were just artists depictions. Nobody could image them well enough to know what they were made of or what their spin rate was, really anything about it, other than its speed and trajectory.
Unless we’re already really good at interstellar travel, what you just described is the suicide of whatever crew was on that ship

I’ve never seen the northern lights that far south on the regular. If you want to see the northern lights in Michigan, you need to get up on the south shore of superior like Copper Harbor. Cherry Springs is nice but most anywhere in the UP is darker.

You’re already kind of near there but I prefer sleeping bear like 40 mins to the SW. you’ll get the lights of Traverse City a little bit more than you do Mackinac city but it’s just an overall easier experience for me. Anywhere you can find a dark spot at sleeping bear you’re good to go. I like the Dune climb parking lot or the place across the street, the Lake shore picnic area.
Here’s a pic I took from sleeping bear.

Nope. Thanks for playing. r/lostredditor is at least asking for directions at the gas station

Reply to comment by cp5184 in Is there a list of live-streaming telescopes? by phil_sci_fi
The stream wouldn’t be super impressive. You’d still need to stack and process the image. You can rent time on fancy internet connected telescopes. I don’t remember the name of the service I used, but you could request specific objects or places in the sky. I had a free trial for one and it was kind of cool, but I’d rather do my own pictures.
It definite wasn’t live. They just sent you the data when they were done but it helped me practice stacking and processing

They’ve been trying out different train configurations. Believe me it’s star link or some other low earth orbit communications satellite. We didn’t find aliens or anything.

It’s just a train of star link satellites. It’s not the end of the world, but I hate those things, that idiot is ruining the night sky for the rest of us.

I second this. Even small binoculars get heavy after a while and high magnification it’s pretty hard to hold steady.

Reply to Maybe you all can settle this debate. What happens when you fire (Wait for it) a gun with a recoil suppression system, such as the KRISS Vector, in vacuum? by TyphusIsDaddy
I own a vector 45 and believe me, it for sure has recoil, but it’s back and up instead of towards my gun hand. It’s a fine firearm, fairly ambidextrous, except for the charging handle, but it ain’t magic. Nothing 100% suppresses recoil, you should encourage your friend to take a physics class.

Not a physicist but the way I understand it you’re always subjected to some amount of gravity in space, but as you’re orbiting the planet/sun/galaxy/center of mass you’re constantly in freefall.
