Mr. spoke is travelling with speed v = 9.4c.
Mr. spoke is apparently unknowing of theory of special relativity by Einstein. The theory states that moving clock tick slower than stationery clock.
Time elapse =∆t = 3 weeks
(In earth stationery frame)
Time ellipse= ∆t' = 1 week
(In the frame of rocket)
∆t' = ∆t'/γ
1/y² = 1 - v²/c²
∆t'²/∆t² =
=1²/3²
=1/9
c= 3×10⁸m/s
on solving above equation we get :
v = 9.4c
He was spreading around at close to the speed of light.
Experience significant time dilatation.
He is travelling with speed v = 9.4c.

Its fake some of its real like the space part and the traveling through space part but not the multi dimensional stuff
it will be very hot so that causes nobody to walk on venus because its the hottest outer planet.
hope I helped :)
To locate a specific target or to determine how close submarines are to the seafloor, they use active and passive sound navigation and ranging (or a SONAR, in simple terms.) It emits pulses of sound waves that travel through the water, reflect off the target and relayed back to the ship. By determining how fast the sound wave travels back, the computers on the sub calculate how far they are from the target.
Hope this helps.
