no i mean, idk how to explain it but pretend u have something in front of you, what is the lowest speed it can go to make it look like it was never there. like you never saw it go left or right, it just disappeared from your sight

[Legacyweapon]

lightspeed?

lightspeed?

Can't be light speed because scientists already broke that speed and they can see it.
There has to be something faster than light speed though. I just dunno what.

Im just spitballin here, but my science teacher says the hands r quicker than the eye. Which means u cant always trust whats in front of ur eyes, and if u do it fast with your hands then it would create an illusion. Most ppl do that in card tricks, although its not the speed of light, but u'll get it. I doubt anything that mankind has made can even go that fast.

[nancy.<3's.you]

its less than the speed of light i know that for sure. im talkin about the human eye here, not some super scientific thingy.

I believe you mean sound, for it is currently impossible to go the speed of light.
If mass were to go at light-speed it's very electrons would be riped from it's place. The material would simply vaporize.
For lightspeed to be achieved one would need something like a forcefield that uses something other than matter to create a shield.
We don't have that yet.

We have gone the speed of sound though, if thats what you meant...



Oh, and before anyone says that what I'm saying is wrong because light goes the speed of light, remember that light is not a mass, but a wave, which is much different than mass, and reacts differently to such speed.

Wait, if the electrons are magnetically ripped from their bond, then wouldn't light do the same when traveling the speed of light? So your saying that every light source is causing electrons to be de-bonded and yet this doesn't affect the atomic balance in things such as our skin. Ok, i'm sorry but explain that again...
I thought we went the speed of light. That's right.. they made a documentary about it.. I think it's called Star Trek or something.

So Star Trek is real, huh? I suppose Harry Potter exists too. And i'm definately sure Middle Earth was an actual place.

yes, if i were to run at the speed of light, my arms would fall off and legs, and head,everything

Not sure if you're being sarcastic or not, but I'll correct it anyway.

It wouldn't be a body part that falls off.
Basically imagine your body made out of sand, sand so fine that it's impossible to see the grains with the human eye.
Now imagine a strong wind blowing you away.

Thats basically what happens to mass at such velocities.
