I always thought, from what sources I forget, that light takes 8 minutes to reach earth...
(Edit) I came from a BBC programme with Brian Cox that stated it took 9 minutes. Makes you think that they’re not telling us everything, perhaps?
Thanks
ОтветитьIf the sun was to just go from not being there to suddenly being there would the light from it reach the earth before the heat from it? If at the same time that would mean light is relative to heat and both travel at the same speed.
ОтветитьNice video
Edit:I’m in school by the way.If you are briargrove elementary school then hi.
pluto dwarfplanet (caugh)
ОтветитьAwesome incredible nature really 🙏🙏🙏🙏🙏🙏
ОтветитьFrom earth we reach to saturn first and then jupiter.. but why this video show jupiter first.?? Im confusing..
ОтветитьFarzi
ОтветитьPluto is not a planet
ОтветитьIf the light of Sun reaches here in 8 min. And on Mars in 12 min. Then the distance between Earth and Mars should be equal to 4 "light minutes".. can we prove this fact? It should be easy then.. a light source on Mars and telescope here and a perfect demo of light speed is ready to be demonstrated (which would be a great direct and firm experiment to measure "The Light Speed" :))
ОтветитьAs per relativity theory, if we travel at speed of light then time become negligible. So If we travel at light speed for 8.3mins then we will reach sun, so how much time would've passed on earth? Isn't it 8.3mins? Where is the time dilation here?
ОтветитьWhat's the true color of the Sun? White or yellow?
ОтветитьRemember Space time and planets time are not same Space 1 day = Earth's many many year's , Space time is very slow.
ОтветитьDamn, light is kinda slow. We need to find something faster.
ОтветитьLight itself doesnt know time, so if you could travel at lightspeed your time would stop and you would travel the whole universe in zero seconds.
ОтветитьThe sun isn't a gas ball.
Within our solar system, it is the ONLY source of light.
