What, anyone can sent shit to the moon now?

We should have claimed the moon U.S. property when we had a chance.

I've got maybe 40 years left on this planet. Hopefully shit doesn't go too sideways in that time.

The Space Treaty signed in 1960-something, prevented that, and continues to prevent countries from claiming celestial objects. I know your post was tongue in cheek, but just mentioning it.

Besides, anything that we do outside of the low earth orbit, should be on behalf of all earthlings. I mean, people always talk about Martians, Kryptonians, etc. No one talks about what portion of Mars or Krypton they're from. They banded together as a single people for the whole planet, and we must as well if we are ever to fight off those attempting to be our alien overlords.

I was reading an interesting article on space junk recently.  We're making a mess up there, and eventually it could severely interfere with satellite activity.  Why are we such fucks?

There are more than 20,000 pieces of debris larger than a softball orbiting the Earth. They travel at speeds up to 17,500 mph, fast enough for a relatively small piece of orbital debris to damage a satellite or a spacecraft. There are 500,000 pieces of debris the size of a marble or larger. There are many millions of pieces of debris that are so small they can’t be tracked.

That's one of the added issues with people blowing up satellites like India just did.  If there became a war of countries shooting down each others' satellites, it would increase the debris like crazy. 1 blown up satellite becomes hundreds of pieces of debris.

I thought I heard that space debris would be one of the things that the new Space Force would be tasked with improving.

OK. Now I have to post this surprisingly catchy tune.

The first picture of a black hole is supposed to be released Wednesday. Well, not OF the black hole itself, because that would be impossible, but of the event horizon and areas around it. Pretty cool global effort, to position radio telescopes in various countries to create an array that effectively makes it an earth-sized telescope, which is necessary in size to capture what they're trying to capture.

Either that, or the big announcement will be to say that they found nothing, and it will be the nerd version of Al Capone's vault.

Light obtains the fastest speed in the known universe.
This black hole exists in a galaxy 50 million light years away.
This means it would take light 50 million years to travel from that galaxy to ours.
How the fuck do we have these pictures?

Sterling Heights was right! That's a golden butt hole.

It's also 6.5 BILLION times the size of our sun, which I think qualifies it as bigger than the Big Hole in AA.

No, because 50 million would be if we were looking at it from earth.  We're peering at least 3 or 4 million light years out, so it's more like 46 million years old.

No, we don't peer out, we only receive light that reaches us. The light that the image shows is 50 million years old (55, actually). Our eyes and our instruments are only receivers of data.

Similarly, if in this M87 galaxy, there is a life form with a powerful enough telescope to see the earth, then right now, looking through that telescope, they would be watching the first modern birds coming into existence about 11 million years after the Dinosaurs went extinct.

So to answer CF's question, we have these pictures that we took now, but the events taking place in it happened 55 million years ago.

I'd still prefer getting sucked in to the black hole than going to a game in the Big Hole.

Obviously not, since you don’t even know about the peer out hypothesis.

A little reading material for Roc on how sight and observing the Universe works.  We are constantly looking back in time.  As you're reading this, Aliens could have opened up a worm hole and sucked our sun away...and you'd be none the wiser, experiencing all the light of day, for more than 8 minutes.

Can one of you smart people ELI5 why you’re speaking in terms of length of time rather than distance, since even a knot head like me knows a light year is a measure of distance, not time.

Thanks a pantsful.

A lightyear measures the distance light travels in one year. When referencing lightyears for anything other than light, only the distance is really relevant (as the amount of time will vary based on speed). For light itself, it is essentially also a measure of time (as light always travels at a constant speed).

Ok, GreenWay, this black hole is almost 17 million parsecs away (yes, I had to google that).  Does that make more sense to you?  No, and not to me either, because no one other than some PhD scientists knows what the fuck a parsec really is (and it ain't the same as used in Star Wars).  Light years is used instead of parsecs in common language so that us somewhat regular folk can kind of grasp the distance.

To expand on what Cameron was saying, there was talk of time because when we see something that is 1 light year away, we are seeing that object as it was one year ago (since light/sight takes 1 year to travel the distance of 1 light year).  Space (distance) and time are effectively one and the same. In fact, when you look at your wife, sitting one meter away, you are not seeing her as she is, but as she was a tiny fraction of a second ago.  We are always viewing the past.

Ok, that all sounded really geeky.

This thing is designed to one day launch rockets from the air.

Seems like it would be disorienting to pilot the Roc from a cockpit on one side. Why not put it in the center?

Just because you get disoriented changing sides of the couch, doesn't mean this matters to trained, professional pilots. Besides, the rocket thingy goes in the middle.

Obviously because that's where the payload will be.

Do you drive your car sitting on the center console?

I don’t recall asking either of you pinheads for some attitude.

[Rocinante]

Yeah bitch. I’ll launch my rocket into your wives.

[pulling69]

Piloting from either side takes some getting used to...You always learn on the left and then captain on the left. You learn to teach on the right and be first officer on the right.

PS Left side is better
