I've watched ton of YouTube videos and I'm not convinced. There are no actual mathematics to support the claim where as there's actually physics and math formulas to support the globe and you can't really argue with math, even the rotation of the earth, it's curveture ect is taken in to affect. Gravity is strong enough to form a globe of the earth. The earth followed the sun's orbit gathering debris, gravity pulls everything to the center so was the earth gsthers more debris send gains more mass it starts to form the earth to be round.

Due to special relativity, this is not the case. At this point, many you guys will only question the validity of any answer which uses advanced, intimidating-sounding physics terms to explain a position. However, it is true. The relevant equation is v/c = tanh (at/c). One will find that in this equation, tanh(at/c) can never exceed or equal 1. This means that velocity can never reach the speed of light, regardless of how long one accelerates for and the rate of the acceleration.
Also; see Nick James' post above concerning all we "know" being hypothesis. You trust this because it's what you've been told. It is not fact and no scientist would claim it to be.
