That's why it's really hard to argue against flat earthers...
Hmm, Really?

Let's see how you do...
I'll keep it as brief as possible ( I currently have ~25 Proofs that are irrefutable). 3 Proofs that settle matters
quite abruptly, so:
1. Pummeling of any Notion of a "Near-Perfect Vacuum" of Space. Whereby obliterating: big bangs, black holes, "gravity waves" (as if they needed anymore bludgeoning

), "nasa" ---IN TOTO, Moon Landings/Missions, Satellites, Hubble Telescope, ISS, Cosmic Microwave Background Radiation (CMB), Every Single Last Codswallop Fraudulent Space Mission, Every Observatory, Every astrophysics/astronomy/ cosmology department and Pseudo-Scientist Lying ---("Knowingly") Psychopath associated with them !
2. The Earth is Stationary.
3. The Earth is Flat.
#1. If there is no physical barrier between Earth's Atmosphere and Space, which there isn't...
"There's no clear boundary between Earth's atmosphere and space, says Dr Kevin Pimbblet, lecturer in astrophysics at the University of Queensland."
http://www.abc.net.au/science/ articles/2010/01/13/2791372. htm
"There is no definite boundary between the atmosphere and outer space."
http://www.cs.mcgill.ca/~ rwest/link-suggestion/wpcd_ 2008-09_augmented/wp/e/Earth% 2527s_atmosphere.htm
"Some experts believe a definition of the boundary of space is impossible to create. Hans Haubold, senior program office at the UN Office for Outer Space Affairs (OOSA), noted that the atmosphere is too “fuzzy for a physics-based definition to ever be established” (Kois 2004)."

Ergo...
How can you have a Vacuum/Near-Perfect (Outer Space) attached to a Non-Vacuum (Earth) and still retain the Properties of a Vacuum and a Non-Vacuum in the same system, simultaneously....?
Can you explain this in a Law of Entropy (2nd Law of Thermodynamics --"Pillar of Science") context?
If there's a "Non Perfect" Vacuum surrounding the Earth's Atmospheric layers as we are 'TOLD', then there should be a colossal cascading chain of envelopment from the Exosphere to Thermosphere to Mesosphere down to your feet like dominoes faster than you can say "
ENTROPY" until equilibrium is reached. Hard Stop!
So @ a minimum, How are you still breathing...?
#2. Coriolis Effect: any object FIXED to the ROTATIONAL FRAME OF REFERENCE will immediately "Slip Out" of that frame of reference when it's no longer Physically Fixed/Restrained to that Rotational Body and is compelled to a direction contrary to that of the Center of Rotation, Hard Stop!!
(If you're unsure of this phenomenon, grab: a friend, merry-go-round, and a ball then have a passerby spin you around.... then play catch.)
So with the unproven "presupposition" of the Earth spinning from West to East @ roughly 1,000 mph, How on Earth can you have a Plane Take Off (NOT FIXED to the ROTATIONAL FRAME OF REFERENCE) from New York to Los Angeles (~5hrs 45 min) --- traveling in the opposing direction of rotation, have the same Flight Time as a the return trip (LA to NY) -- traveling with the rotation??
The westbound flight from NY to LA, say @ 500 mph typical cruising speed, would have a higher relative speed --- i.e., you need to add the speed of the opposing ROTATIONAL FRAME OF REFERENCE of the Earth 1,000 mph to the Plane's Speed; i.e., 500 mph + 1000 mph = 1500 mph.
The eastbound flight from LA to NY will immediately "Slip Out" of the ROTATIONAL FRAME OF REFERENCE upon Take Off/climbing to cruising altitude --- and @ the same 500 mph ---which has to be subtracted from the ROTATIONAL FRAME OF REFERENCE since that's the same direction; i.e., 1000 mph (Earth's Rotational Speed) - 500 mph (Plane's Speed) = 500 mph, will not only "Conceptually" take 3 TIMES as long, but Practically, "In Reality".....
NEVER CATCH UP to it's Destination (NY) before it gets BUM RUSHED by said Destination @ 500 mph!!!
Furthermore, why couldn't East Coasters not just hop in a Air Balloon or a Helicopter and hover (Not FIXED to the ROTATIONAL FRAME OF REFERENCE) for 3 hours and catch a Dodger Game...?
If I'm making a north-south shot @ 1,000 meters on a Calm Day with a Muzzle Velocity of 1,000 m/s ...with the Earth allegedly "Spinning" @ 1,000 mph ( 447 m/s ) from west to east beneath the bullet ( "Slipping Out" of that Reference Frame when Fired ), then my windage adjustment should be 447 meters to the east of center mass of the target.
That's scenario is a Tear Jerkin Belly Laugher, to be quite frank.
ps. I was in Combat Arms (Reconnaissance) for 8 years and cross-trained with an Elite Sniper Platoon...which was right down the hall, on numerous occasions. I've personally made shots @ 1100-1500 meters. The 'Coriolis Effect' was never brought up ONCE much less practiced!
I have a Naval Weapons Instructor, US Army Artillery Radar Operator, US Army Master Gunner, and a US Army Navigator and Ground Training Combat Expert not only Corroborating my Testimony but extending it by Tens of Miles!
#3. Navy Rail Gun: "Projectile" (Bullet) travels @ 5,600 mph (Mach 7!!)...
"The 6-inch guns that the Navy currently uses have a range of 15 miles; the 16-inch guns of World War II had a range of 24 miles, and could penetrate 30 feet of concrete. The 38-foot railgun, though,
has a range of 125 miles, five times the impact, and can shoot through seven steel plates."
http://rare.us/story/the-navy- just-unveiled-the-first-video- of-their-new-railgun-in- action-and-it-is-awesome/
This is a "Line of Sight" (LOS) Weapon. With a more than 'Generous' Deck/Rail Height of 100 Feet above Sea Level, a target @ 125 miles on our 'alleged' "Spinning Ball" with a radius of 3959 miles will be hidden behind 8476 Feet (1.6 MILES!) of Water/Earth Curvature!
The Horizon @ 100 ft elevation is @ 12.25 Miles.
The 'Bulge' height is 2604 feet.
Target Hidden Height is 8,476 feet.
Calculator: https://www. metabunk.org/curve/
Ergo, Please explain how a Non Self-Propelled 25 lbs "Projectile" ( A "BULLET") can negotiate a "Bulge Height" of 2604 feet (ascent then descent) traveling @ Mach 7 (lol) and hit a target that's hidden behind 8,476 feet of curvature without violating every Ballistics/Physical Law (and common sense) known to mankind ....?
Let's employ some
actual "
Science", (it should limit the responses by
Exponential Magnitudes in this thread

)...
NULL HYPOTHESIS:
"To do a hypothesis test, you will actual have two hypotheses: the null hypothesis and the alternative hypothesis, which are stated in such a way that they are mutually exclusive (you can’t have both hypotheses be true). The null hypothesis is the conclusion that is considered
the default – you will accept this hypothesis if you fail to find sufficient support for the alternative hypothesis."
http://www.csun.edu/~dgw61315/ECON309lect7Bhypotesting.doc
Null Hypothesis:
IF the Earth is Flat, THEN shots taken with Line of Sight 'LOS' weapons (Non Self-Propelled Projectiles-- "BULLETS")
WILL NOT BE limited to the Earth's "alleged" Curvature ('Bulge' and target 'Hidden Amount') to effectively engage targets for said distance/elevation according to (
https://www.metabunk.org/curve/ ).
Alternative Hypothesis:
IF the Earth is "Sphere", with a circumference of 24,901 miles (radius 3959 miles), THEN shots taken with Line of Sight 'LOS' weapons (Non Self-Propelled Projectiles -- "BULLETS")
WILL BE limited to the Earth's curvature ('Bulge' and target 'Hidden Amount') to effectively engage targets for said distance/elevation according to (
https://www.metabunk.org/curve/ ).
Falsify the Null....? If you can't, then ya hear that sound...that's your Blind 'Faith-Based" Parroted 'World View' circling the drain @ Light Speed!
Let's go ahead and VALIDATE The Null...
TEST: Already Validated (See above "
125 miles"): The Naval 'Rail Gun' Line of Sight (LOS) Weapon (Non Self-Propelled "Projectile"-- "A BULLET" ) can effectively engage targets @
125 miles, well WELL beyond limitations for Earth's "alleged" Curvature; Ergo...the Earth is Flat!! Simple
You might as well: clean out the gutters, trim your nails, do the dishes, attempt to square the circle... ect ect @ this point; Scientifically, the postulate that the Earth is a "Spinning Ball"

... is Kaput!! Phlogiston is more tenable.
Go ahead...?
