What if the heavens we have gazed in wonder for so long are not so vast...but in fact smaller than the landmass we inhabit?

Unlike the ridiculous flat earth theory, which makes no sense, this new theory makes a lot of sense, and not only that, it manages to combine science with religion in a rational, logical way.

I'm trying to make an astronomy club but I don't know what it would be about or what to do. Everyone else who likes astronomy are just shy like me and we all refuse to talk. Logically I know that the club show be at night because astronomy but what do you think I should do at such a club. Thank you

Im looking for a telescope in the 150-180 range for my cousin
can someone knowledgable help me

some of these have more "zoom" I am retarded but are some are cheaper and some have less and are more expensive so I don't get it?

Go for something with a larger aperture size. This collects more light, allowing lenses with more zoom to be used without everything fading out.
I'd recommend something with a 4"+ aperture. It will come with at least a 40mm eyepiece, and if your cousin wants, they can get other lenses that will zoom more.

So imagine you have two cannons firing their cannon balls away from each other, and their muzzle velocity is the speed of light.

You'd think the relative speed of one cannon ball to the other would be 2x the speed of light, right?

Nope. The equation for relative speed between two objects looks like this:

>v1+2=v1+v2/(1+v1v2/c^2)

Where v1 and v2 are the speeds of the two cannon balls and c is the speed of light.

So as the velocity of the cannon balls approaches the speed of light, their own speed doesn't matter and the limit of light speed is dominant. Relative speed of 2x speed of light is thus impossible.

Or in other words: wat.


You guys got some other relativistic mind-blowers?

https://www.cnet.com/news/interstellar-asteroid-comet-a-2017-u1-pan-starrs-nasa-earth/

>All the asteroids and comets astronomers have ever spotted in our celestial neighborhood appear to come from somewhere else in the solar system and orbit the sun, just like Earth.

That is, until the University of Hawaii's Pan-STARRS 1 telescope last week discovered what appears to be the first ever seen "interstellar object" -- an asteroid (or maybe a comet) that escaped from the gravitational grasp of another star and fell through the roof of our solar system.

That makes the object currently designated A/2017 U1 an alien of sorts around our corner of the cosmos.

The foreign space-something is less than a quarter-mile (400 meters) across, but is moving super fast at 15.8 miles (25.5 kilometers) per second. That's over three times faster than Asteroid 2012 TC4, the rock that gave Earth a close shave earlier this month.

"This is the most extreme orbit I have ever seen," said Davide Farnocchia, at NASA's Center for Near-Earth Object Studies (CNEOS). "It is going extremely fast and on such a trajectory that we can say with confidence that this object is on its way out of the solar system and not coming back."

I was wondering why you guys post here? Aren't these boards ungodly slow? Wouldn't it be easier for you to just go to an actual forum for space discussion? Why wait so long for a reply from some drug addict about stars or whatever when you can probably get better information more quickly from somewhere else?

Not judging, just genuinely curious

yep, very good. now let's break down relativism: that which is relative [to a given frame of reference]; i.e. you make up your own system as an observer, which will be different from every other observer's system. an object in motion in relation to another object in motion can only have a determinate speed (if we are serious about this conversation we should start using the term velocity, actually) within a predetermined system.

The budget is what makes it impossible. As such, humans don't deserve to leave. Money and the idea of it holds us back more than people will ever realize. If man would just stop being selfish and/or trying to control others, we would be so far ahead. Those that want to waste away would be allowed to and those that want to do something great would be able to, because without money, the only thing holding you back would be yourself. In this life, it's both other people and money.

It was late august and the skies were perfect out in the cornfields of Nebraska,
It was the darkest I've ever seen, I couldn't see my hand in front of me, let alone the stalks.

After about half an hour of stumbling through the field trying to find my spot, (a clearing that my friend used to grow weed) I finally stumbled upon a small trail that led to the clearing.

In the clearing there was a trailer, a lawnchair, a cooler and a telescope. I turned on my lantern and went into the trailer. There were stalks of weed hanging on clotheslines as well as a few pills scattered on a table with a note that said "help yourself", with a winky face alongside a condom.

I thought it was a prank, but I thought I might as well so I took the pills all at once and shaved off a nug branch of uncured weed and smoked it the best I could. Anyway I got out my telescope and used my night-sky app on my phone to find the planets (yeah I know, I'm lazy).

As I was focusing in on Saturn I noticed my vision started to blur a bit. I thought at first the lense was just out of focus but I soon found that something was happening. I continued my search anyway, the best I could until I could no longer keep up.

I decided to just chill on a tarp and watch the stars instead, see If I could make out the ISS and other satellites. I started thinking about how those stars are actually clusters of galaxies that are probably gone, it made me sad but then I felt something.

My dick was hard as a rock., On top of that the stars wouldn't stay still. It was bothering the fuck out of me until it didn't. I started to see my own constellations, they turned into titties and even full on line-porn.

SO I jacked off to the night sky for about 2 hours straight.
it felt amazing, I'm not even ashamed.

so cern was built and there were quite a few expermiments done there, now i am wondering why we are shooting particles through earth "for different reasons" are we measuring for a difference in gravity? also i read an really awkward article about alot of stars and planets naturally containing black holes (sounds like the cancer lie to me - its natural and in every body in low amounts- and i have cancer and know how i got it - chemically) so whats goind on here? possibly does anyone know the maths to how fast a black hole grows? just asking ...

You're reaching into subject matter that I think you probably need more reference knowledge for to be able to integrate fully. Probably best to just not worry about such things in that case.
But, the idea that there could be microscopic black holes capable of passing through the earth is just from one study by one physicist, as a way to explain something that probably has a much simpler explanation i.e. the LHC doesn't generate micro black holes simply because the LHC isn't capable of generating micro black holes . The accepted explanation concerning black holes in the standard model is that they continually lose mass due to Hawking radiation, and thus eventually evaporate completely, so by most physicists estimation, long lived subatomic scale black holes don't exist.

If there were a black hole in the center of the earth, then the center of the earth would fall into its event horizon, which would subsequently expand. In short order, the entire earth would be within the black hole. Anything that comes into physical contact with the event horizon becomes a part of the black hole, and since the center of the earth is completely pressurized with no vacuous space, it would consume the earth more or less instantaneously from our perspective, from the inside out.

The amount of the mass that subatomic particles, that could pass through such an object that weren't already part of the earth's mass -- like neutrinos burrowing through from the sun, would contribute to the total mass of an earth-consuming black hole would be vanishingly negligible, more or less equivalent to the number of neutrinos that pass through the earth during the time it took the black hole to consume it, (which would again, would on the order of seconds, perhaps minutes) pico grams of substance compared to the earth's 5x10^24 Kgs.
