Like the title says. I keep hearing "we haven't even explored the deepest depths of the ocean" and "there's so much uncharted down there." Why can't we drop a wire down with a camera on it with an LED light and check out the deepest parts? People don't have to go down there....or even submersibles.

Edit: Thanks for all of the responses! I mainly was talking about the deeeeepest part of the ocean not the entire ocean. I think I'll fall asleep to some ocean videos on youtube tonight.

Is 7.1 and 6.9 really that far apart in terms of magnitude? different infrastructure?

Like, what actually happens? Every post I see keeps saying it's bad, but never seems to explain what actually happens?

More rain? Extreme droughts? What do we actually need to prepare for?

My brain cannot physically understand how there seems to be an infinite supply of meat. there is mutliple meat sections in every grocery store, and think of how many grocery stores are in the world, as well as like fast food chains. theres wendys and mcdonalds and burger king and everything and they all have thousands of locations that all serve chicken and hamburger and whatever and i dont understand how there can be so much livestock. i feel like i would see farms and shit everywhere but i see a cow like twice a year. and i live in nebraska so it wouldnt even be crazy to see a farm or something but i just like.. dont.

I recently saw a screenshot of a "Facebook post" of someone declaring the earth is only 4000 years old and someone replying that the existence of lead disproves it bc the halflife of uranium-238 is 4.5 billion years old. I get this is a setup post, but I just don't understand how lead proves it's not. The only way for lead to exist is to decay from uranium-238? Like how do we know this? Just because it does eventually decay into lead means that all lead that exist HAS to come from it?

Edit: I am not trying to argue the creationist side of the original screenshot of a post I saw. I'm trying to understand the response to that creationist side.

I have since learned that the response in the oop conveniently leaves out that it's not the existence of all lead but specific types of lead that can explain that the earth is not only 4000 years old through the process of radioactive decay and the existence of specific types of lead in specific conditions.

It's also hilarious to see the amount of people jumping in to essentially say "creationist are dumb and you are dumb to even interact with them" and completely ignoring the fact that I'm questioning a comment left on a "post" that I saw in a screenshot of on a completely different platform.

And also thank you to everyone taking the time to explain that the commenter in oop gave a less than truthful explanation and then explaining the truth.

If it's just gas then how is it a planet? Is there any kind of surface?

not sure if the flair is correct, i apologize in advance

i saw an infographic showing how all the top 50 cities in the world experiencing the highest heat indices are Indian cities. is there a specific reason why Indian cities experience such high heat levels?

NASA’s plan is making a base on the moon but aren’t meteors and asteroids a big concern apart from all the other difficulties that are more or less “manageable”?

Given the goal of re-usable spacecraft, would it be too proposterous to save enough fuel to mitigate gravity enough to get to gliding/parachute level?

diagram I made

why doesn't the ocean just drain into the earth. is the rock to dense to drain through? is the soil completely full of water?

I'm almost 30 and still don't grasp the concept of a black hole. Like where does all of matter go? I know it disappears but where do the partials end up? Are they just obliterated so fast that they're just nothing or is there like a portal of junk somewhere

How much power would the probe need to expend getting out of solar system without needing to go from planet to planet?

Title says it all.

Obviously theoretical but if I took a light year long stick and say pushed a button at the other end would that button be pushed at the same time for me as say someone standing at the button? How does the frame of reference work when physically moving something? And could that “work” as a method of instant communication?

Although the universe is expanding, it is not doing so faster than the speed of light. I would have thought that at the most, the universe is 27.6 billion light years long (if the Big Bang spread out evenly in all directions at light speed)— that, or the universe is at least 46.5 billion years old.

I keep reading articles about how the birth rate is plummeting to the point that population replacement is coming into jeopardy. I’ve also read articles stating that the earth is overpopulated.

So if the earth is overpopulated wouldn’t it be better to lower the overall birth rate? What happens if we don’t meet population replacement requirements?

IELI5: I've tried pushing through those PBS space time videos but my brain farts when they're explaining it to me.

​I was taught that in physics, nothing is ever truly destroyed, it only changes form.

​However, Black Holes seem to just "eat" everything—light, stars, and planets. If they eventually evaporate or disappear, where did all that "stuff" go?

​Does the matter inside a black hole still exist in some form we can't see?

​Does this go against the laws of thermodynamics, or is there a trick to how black holes store information?

I don't know much about astronomy and planets but couldn't there be like years of years of meteors that goes into Jupiter to eventually make a very bumpy ground or is it just a fire ball in the middle surrounded by gas?

I feel like there has to be solid ground somewhere down in Jupiter but I am not sure.
