1. ### Does stopping a very fast object makes it lighter?

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"...
2. ### Does stopping a very fast object makes it lighter?

sorry..lets omit the "to not reaching c" i expect answer. scenario is part of the query. oh.. is relativity passe
3. ### Does stopping a very fast object makes it lighter?

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...
4. ### Does stopping a very fast object makes it lighter?

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..
5. ### Does stopping a very fast object makes it lighter?

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?
6. ### Does stopping a very fast object makes it lighter?

time \downarrow m=1 ...:cool:... fast moving v=c/2--> m=1 ...:grumpy:<--F=1... x=0 start stopping v=c/2--> m=? ...:mad:<--F=0... x=1 End here v=0
7. ### Quick Thinking Question

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...
8. ### Quick Thinking Question

No, different acceleration is experienced due to altitude but the probability could be the same
9. ### Does stopping a very fast object makes it lighter?

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
10. ### Does stopping a very fast object makes it lighter?

Hey guys, If we stop a very fast moving object will it lose weight ?..i need a hand on this matter. Thanks
11. ### Is it possible to see objects move faster than c?

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
12. ### I wanted to know how it is determined uncertainty

is uncertainty applicable with the speed of light? like 3x10^8m/s≥c
13. ### Is it possible to see objects move faster than c?

oh i see.. distance is not an object too
14. ### Is it possible to see objects move faster than c?

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
15. ### How do springs work?

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...
16. ### Race across the Universe:Who is on edge? Force Vs. Light

well..i don't like research work. i guess it will really take a while I just try the similar threads below. Thanks again
17. ### Race across the Universe:Who is on edge? Force Vs. Light

The SPACE is confirmed flat and open..but Universe is not Space
18. ### Race across the Universe:Who is on edge? Force Vs. Light

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)...
19. ### Race across the Universe:Who is on edge? Force Vs. Light

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.
20. ### Race across the Universe:Who is on edge? Force Vs. Light

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...
21. ### Which comes first matter or energy?

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
22. ### Is it possible to see objects move faster than c?

http://www.youtube.com/watch?v=lR4tJr7sMPM&feature=relmfu Laser on moon moves faster than c..
23. ### Which comes first matter or energy?

Right..Youtube as i recall it. Thanks! ..By the way, How can i describe "all was energy" ? what kind of energy? Momentum? Heat? Photon?
24. ### Which comes first matter or energy?

Yeah! as i thought.. but what about this they saying in BBT ; "a pointlike thing with infinite mass/density?"
25. ### Which comes first matter or energy?

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...
