confusing one mfb
you mean That is right only if I use abandoned definition of "mass".
so where can i get this decades old "mass'' definition?
I am new to science and starting on "emersion stage" and afraid someday i shall reach the "i had enough-of-it stage"...
What if the object is a meteor that just missed the moon and is suddenly prevented by a superman from colliding with our planet successfully halted before entering the atmosphere?
Maybe far out example of no heat exchange involved, the doubt is: when we push on object it would gain mass to not...
correction.."light electron" is not especial. same as any electron at rest..
#10 Interesting , thanks
a reliable source informed me that minimum mass of an object is when it is at rest..
Awesome! mass was decreased then we have "light electron"
but will the -e absorb radiation & increase mass if magnet field is reverse to accelerate it?
Doing that on top of the high mountain is the same.. no acceleration but different g "acceleration due to gravity due to altitude" (should have use that phrase in my last post).
Thus, lighter "darts" to throw . Aiming is a matter of memorizing the motor complex for certain dart flight..try 3...
No ideal what to add..
maybe: speed of moving object = half c , stop point in reference to the point of initial contact..
in a way , since you mention "unless" i assumed it is positive
At any point in time ,our (galaxy) have relative speed to any galaxy..different frames of reference w/ same physics.. but as the space expand w/ accelaration can the relative speed exceeds 1?
or we are we co-moving with them even the distance between us galaxies increases
refer #12
Somewhere on my readings here in the forums i happen to read about galaxy can move faster. it involves the apparent expansion of space.. i lost that thread sorry
it is a mechanics of material that is involve .. a long round bar stretched along its ends..lengthens & thins ,when compressed.. it shortens & fattens, (the change in shape in not noticeable) . Releasing.. it return to original structure (wear/tear builds up). If twisted or bended it also...
Yeah, i mistook that speed comparison is the same as which ever is ahead on the edge of the Universe is faster.. i was tipped that the "speed of force" = c , the only difference therefore is which (light or force) have the head start, but since the light some how can be held back by force (GR)...
Its like..what if the light journey is being affected by gravity (or curvature?) along the way.. classic sample is the rabbit-turtle race where the rabbit being confident have napped himself to perdition.
Hey there guys,
I remembered one stormy night while playing Atari racing game with my son..he asked me: "what is faster force of light?" I escaped with a reply .. "flash first..thunder later" .Suddenly the power was out. My kid went to fetch the flashlight and said to me.."look! push first...
Einstein said photon is particle of energy..and 2 photons collision creates mass particle + anti-mass particle...so far Energy of Light wins 5-0 or with a draw
Hey there guys, i had an argument with my office mate during a lunch about "Which comes first -the energy or matter?" Maybe it pop out because I am having crab omelet (egg) while he has (chicken) salad.. but anyway it was unsettled and i would appreciate any help. I am sure he is on net...
