Every time i think of the origin of God, it feels bad, like, I know we all came from god, but where did he... just makes me feel like i'm sinning. It is weird
Light is relative to speed, because us seeing light is relative to what it gets bounced off of, so we speed it up every time we see sometihng moving. or smething...
I didn't quite catch that.
I often like to think about relative speed, the way my pathetic logic understands is that we cannot travel faster than the speed of light (relative speed) because we have mass. However the while the relative speed will not change in a vacuum, its speed is effected my the direction and speed of the object that emits it. The speed will be 299,792,458 (speed of light) plus whatever the speed of the object it is emitted from, (assuming they are both going in the same direction.
The reason I assume this is because. While I am stood still doing 0 mph, I am actually rotating around the earth at whatever speed, I am also hurtling around the sun at thousands of mph, crashing around the out region of our galaxy, immense speed, plus Speeding through the universe at unknown speed, so basically relative to the universe I am traveling at millions mph. relative to me I am doing 0mph.
In this respect, If I was not hurtling through the universe and was absolutly still i.e 0mph, in a vacuum emitting light, then light would travel at 299,792,458m/s exactly. However If I was traveling at 10,000m/s, in a direction, then light emitted in the same direction I travel will travel 299,792,458 plus 10,000m/s, therefore 299,802,458, while the light emitted in the complete opposite direction to my travel will travel at 299,792,458 minus 10,000mph therefore 299,782,458m/s this means to an observer traveling at 0m/s light will travel faster in one direction, in this case 20,000m/s difference yet relative to me they are are both traveling equal speed away from me, it sounds weird yet obvious at the same time. How can they travel at different speeds yet at the same speed?
Well the same can happen with difference if we talk about relative distance. My school physics teacher mentioned this bit in class one day. If you are inside a train doing 100 mph, you bounce a ball 1 meter down. like in this diagram.
Relative to you the ball drops directly down and back up, one meter down one meter up.
Now here comes the difference. Relative to an external observer. Things change. Here is the same bounce observed by someone else outside the train.
Relative to the observer off the train the ball will actually travel much further, there is no right or wrong answer only how it is observed. If you do a 100meter sprint,
relative to the sun will travel thousands of metres by the end of the race,
relative to you it is just a petty 100meters you will travel.
As previously stated this is how light travels at different speeds however its relative speed never changes unless it comes into contact with other things e.g air.
Its interesting to think about and probably incorrect, since it is the mere assumptions of a 16 year old, nonetheless it is something to think about.
