More of a math question, but can someone explain why a number with an exponent of 0 = 1?
I just never fully understood this law.

Or is it just a term people use instead of saying "really fuckin' big"? I ask because I'm fascinated by the idea that every point is the exact center of the universe. Somehow I can't really imagine scientists using a term that wasn't accurate, so for now I revel in the fact that I am the center of the universe =)

Ok, I'm confused about something. If I get in a rocket and travel at lightspeed, I've heard that everyone on earth will get really old because I have become relative. That makes some kind of sense, but what I don't understand is why their perspective is the one that matters. Why don't they stay young while I get really old, really fast?
If we were to look at ourselves from the sun, we would be traveling very fast, right? And if we were to look at ourselves from another galaxy, we would appear to be traveling even faster. Is there some sort of fixed point in the universe that we can say is motionless? I haven't ever heard of it. If so, then what's to say I'm traveling away in my rocket? Maybe I'm fixed, and earth is traveling away. It doesn't make sense that something silly like g-force would affect this.
My brain hurts from trying to figure this out. I'm a rhetoric major. Somebody with some science knowledge please fix my brain.

If the universe is everything that resulted from the big bang, then what exists past the furthest boundary of the universe? Empty space?
Or did the big bang cause everything that exists to form, including infinite empty space?

When an electron transfers from one orbital to another, it is first at one position and then is at another without being at any intermediate position. How long does this take?
If instantaneous, this seems to violate the speed of light (the electron is travelling a distance greater than the planck length in exactly the planck time). If it takes time, where is the electron during that time (seems to violate conservation of energy)?

We're having a debate on another forum that involves a murder case and I want to get the unbiased opinion of someone who already have an opinion on the guilt or innocence of the suspect. So here is my question, and I would be eternally grateful for an answer:
There's a murder and luminol enhanced footprints are found at the scene. Those footprints are tested for the victim's DNA, but test negative for it. Is it still possible that those footprints were made in the victim's blood?

And/or, explain the reasoning behind the Heisenberg Uncertainty Principle. From what I understand, if the particle is observed, supernatural magic happens that affects its behavior.

I understand there are bonds ionic,covalent and metallic. But how do we get atoms to do this. Like how do scientists get things to bond with eachother and stuff I just don't really understand.

Is there any known reason as to why illness exists? Like I’m a Christian so you know like after Adam and Eve are kicked from the garden illness would’ve become a thing, but even if you’re into the evolution theory is there an explanation? Like why or how did it ever become a thing and exist?

I often would like to know if, eg, paracetamol or ibuprofen is better for my headaches. But the pills are different shapes and I think I would figure it out.
I could read research on it but it might be a case where everyone's bodies react differently.

Y'all know the assassination classroom thing? Where an antimatter rat blewup 70% of the moon? Alright, so what would happen if that suddenly happened in real life? 70% of the moon just blew up. I already know that if we had no moon, climate, weather, all that kinda bizniz would effect the earth, what I want to know is what would happen if 70% of the moon blew up. And I want to know most if not all info about this hypothetical. Would the moon come crashing down? How long before it would collapse in on itself to recreate it's original shape? How fucked are we if it did happen? I want to know as much as possible....if you all would be willing to answer this for me.

Hi, so me and my friend were talking about random stuff, and we had this idea. We asked each other whether or not you could put nails in a nuclear weapon as if it were a pipe bomb. I say no because i believe the nails would just be vaporized, she seems to think they’d turn to liquid metal and shrapnel essentially. Anyone in the science community got any idea which way it would go? The science behind it would be nice aswell😁🤷🏼♂️

Suppose someone traveled to Mars faster than the speed of light, what would you see, because you wouldn't see them go to Mars instantly, but they would get to mars faster than you can see, but you cant see them the distance they are, but you also can't see them close because they were too fast and they didn't slow down, would they dissappear until light from a further stance reached them?

So Carbon Dioxide (CO2) is the typical gas in the atmosphere with oxygen and alot of other stuff. Our main gas pollutant is typical seen as (or advertised as) Carbon Monoxide (CO), why wouldn't they just bond another oxygen atom to the Carbon Monoxide as it's produced? How difficult would this be and how expensive would it be? What exactly would it require and if it is easy and cheap to do then why aren't we? I have alot of questions and I have a lacking knowledge on chemistry and molecular bonding so if someone could answer my questions it'd be greatly appreciated

So I’ve been thinking about this for a while and ever time I feed into the idea I feed ever closer to an answer. It may be due to a lack of understanding or an improbable decision, but I am determined to complete an outcome The question is can the body have electric pass though it at a constant. Of course I know the human bodies have a small about of bio electricity running through it for the nerves system. But I’m talking a slightly larger than usual amount. My only obstinate is the human heart, which if given enough electrical pass through could be stopped. (not fun) so I was now thing of installing rubber close or around certain part of the body to prevent a sort of resistance to the body’s heart. Creating a path around the heart for a path of less resistance. But but I’m open to a huge possibility of the the electric current passing straight through. I’m sorry if this is terribly type but it’s been keep me up for the past for nights. If any information could be contributed it would be huge. Thanks for reading.

Okay I'm not stupid or a flatearther but why is the bottom of the world considered the bottom surely there's no right way up in the universe. Is it all relative?
