If I flung you into space and you continued to travel forever, youd likely not ever hit a single thing.

Reply to Fear of space/bright stars.. by throwawaymanop
The chance of a star besides the sun coming close enough to kick the earth out of the solar system is 1/100,000 in the next 5 BILLION years. The chance of another star colliding with the sun or us is astronomically unlikely. We would have known about any near earth meteor big enough to cause extinction for a long time now.

Meteors move very fast across the sky; they don't look anything like stars. Almost all meteors you see are very small and burn to ash before they hit the ground.

The chances that you personally will be hit and killed by a meteorite? Effectively zero. Significantly smaller than your chance of being eaten by a shark while being struck by lightning.
The chances that a world-destroying asteroid will hit the Earth without warning are also effectively zero. NASA tracks all the medium-sized and larger asteroids that will, have, or may cross or approach Earth's orbit, and none (total zero) of the ones big enough to destroy a large area like a city are likely to hit us in the lifetime of anyone now alive.

A library. You can read what they have and have other literature sent to you at the Library from other places that have what they don't.

Reply to Xenophobia of black holes? by ZAlexN
It's not irrational to fear an all devouring, insatiable gravitational pit.
Unless you are safely thousands of lightyears from any of them.

I assume you mean phobia and not actual xenophobia. I get similar feelings with black holes and any other large space object, really. Mainly in media, though. For example, Elite Dangerous. I was playing that game and discovered a black hole, albeit an extremely small one. For some reason, when I got near it, I felt panicked looking at it. All I felt was a need to get away from this thing as soon as possible. Very strange feeling.

This is a really good analogy. I like it and may need to steal it next time i get the question about higher dimensions

Sci-fi might not be welcomed here, but the Dark Forest theory makes some sense.

Concur. Nature is nothing if not efficient. Why operationalize surplus effort? Multiple universes is out of character. Atypical. Nature optimizes.
Mathematical string theory etc is all good on paper but as per the Feynman explainer, all the 5 zillion potential states cancel each other out until you get one solution that's most probably real.
I comment as a know-nothing. Hi Reddit!

I don’t need evidence to know something is true when my gut already knows from faith and facts provided.
Black holes have a singularity and the Big Bang had a singularity. Put it together

Infinite time doesn't have to mean endless possibilities. Everything could all play out the exact same way an infinite number of times. Nothing has to change between instances of a repeating universe.
You can also have a finite starting point that expands endlessly to infinity, like a simple graph that keeps going up and up and up the farther you plot it. If the universe keeps expanding and entropy keeps increasing, eventually you get a cold universe where everything is too far apart and too depleted for anything new to happen. Even though many different things happened earlier in that universe, all of its future will be spent quietly in the dark with everything more or less uniform.

>It seems like multiple universes would require a near infinite amount of energy to maintain itself
Time could be infinite, space could be infinite, our universe could keep expanding infinitely. Why would an infinite amount of energy to go along with that be a problem, as long as everything follows the usual rules at any particular location?
Once you step outside of our universe, time and space and energy might not mean the same things anyway. Imagine a giant twisty extra-dimensional sculpture containing every moment of our universe, with everything figuratively set in stone for any outside observers. Or an environment where everything can pop in or out of existence spontaneously. It's pointless to get too hung up on the rules and limitations inside our universe when speculating about what could exist outside of it.

Whilst it's trie but entirely trivial that what is ... is. Claims do need evidence to be taken seriously and we can't know what is without evidence.

Reply to Where can I find the most DETAILED accounts of the moon landings? by ostensibly_hurt
At one point in time, there was a post that offered the actual audio of the mission, transcripts, and animations of what was happening while those recordings played.
It was like Apollo in real time, but with an animation. I really liked it, but haven’t been able to find it since.
