I know what you are going to say, “google it”. But according to google, solar sails work by harnessing the light. each particle of light has momentum, and it uses these to accelerate. but i thought that momentum was equal to mass times velocity, and according to the laws of physics and einstein’s law of relativity,...
At some point during their orbit, the location of the Earth and Moon relative to the Sun will be as shown in the figure below. What are the magnitude, in N, and direction of the force experienced by the Moon, in degrees below the Sun-Moon line, due to the Sun and the Earth? (The mass of the Moon is 7.35 1022 kg,...
Life sentence, just inside the event horizon of a black hole.
More matter ? Yes. Matter more, No.
They can't be too worried about the impact, since Moonbeam is still pouring more $billions into their bullet train to nowhere.
How about if you travel faster than light using the Alcubierre Warp Drive?? What would be its temporal effect??
cause he said it himself , if you travel faster than light you 're gonna be bending Time . which is not possible . so what is he hiding by going faster than light only for himself ?
No. Infrared is safe, but one must be careful not to get too warm, as in direct sunlight on a hot day.
They only turned me upright today but yes indeed
I believe that Infinity is Infinity
They say Blck Holes are singularities of Infinite Mass
But how could anything that stops be infinite
The same goes for the Big Bang
Something happened to cause it
My favourite quip is that it was a Quark of Nature
Radio waves have a large wavelength from 3 meters to more than a kilometer. Therefore the energy transferred to the human body during its passage is low. However, near the transponders used for cellphones, the energy is high and so a distance of separation must be maintained to prevent any harm to the body caused...
relativistic speed addition
S = (v+u)/(1+vu/c²)
S = (0.9c+0.9c)/(1+(0.9c)(0.9c)/c²)
S = (1.8c)/(1+0.81)
S = (1.8c)/(1.81)
S = 0.994c
