infinity is our assumption of things which we think is unknown.few yrs ago when we didn't have the tools to measure the d btw earth and moon we called it infinite.don't u think we create a wall infront of our imagination and get satisfied wth it?

Distances at sea level are measured in nautical miles. A nautical mile is about 1.85kms. The speed of the ship is expressed in knots w/c are nautical miles per hour. When a ship is travelling at 20 knots, how many kilometers per hour is it travelling?

If time slows down according to e=mc^2 (Twin Paradox) then you could, in theory, travel so fast that time could be relatively 0 (or very close to it). If rt=d and the rate of speed is whatever that rate is and the time is 0 or very close to it, the distance traveled would be 0 or very close to it. So, there is a point at which it doesn't do any good to travel any faster b/c the distance traveled would be less.

a charged particle in motion creates an electromagnetic wave. (one property of light)
An electromagnetic wave passing through a conductor creates a charged particle to move through the conductor. (the other property of light).
Ergo since light has both properties mentioned and it moves through space, space must be a conductor.. and it's so cold as to offer zero resistance to light, it must be a superconductor.Right?

The coefficient of friction between a box and an inclined plane is 0.35. What is the maximum angle required for the box to stay on the incline and not slide of the incline? if the weight of the object is 100N

some one told me :
100*sin x =0.35*100*cos x
sin x/cos x = 0.35
tan x = 0.35
x = Arctan(0.35)
x = 19.29 degrees

do i need to put the 19.25 in to the formula. like:
100sin19.25 gives me 33.2 degrees, is 33.2 the the maximum angle that the box can stay on the incline plane

according to the theory of relativity its Impossible to go the speed of light because if you spend any time at 1.0c (the speed of light) you are compressed infinitely and one year to you will be infinity to everybody else. Why can light itself get away with this? Wouldnt it not even exist to us? Can someone tell me what im missing?

I don't think time travel to past is possible, but travel to future might be possible, i have personally experienced it!
i went on a ride with my bike one night and it was my first bike ride in years so I hadn't felt how cool it was to ride a bike with fast speed in a long time since I was a kid.

So I leave home at about 9.38 pm and go for a ride by myself. I'm going do fast with my bike and enjoying it so much and I keep going very very fast just to enjoy how it feels. My friends were just watching TV when I had left. So they're still watching TV and chiilin, wandering around the house doing wat they usually do in the evenings. Meanwhile I am enjoying my ride and remember I'm riding very fast.
So anyway I come home at about twenty five to eleven, my friends are all worried and stuff, they're like 'WTF@&! Where u bin!?' And I'm like 'Chill y'all just gone for a ride man'

Anyway when I came back home that night it just felt like time travel could so be possible if I had been travelling at a much faster speed and I mean a lot faster speed. I mean my friends were just sitting there at home not doing much and I was out there experiencing so much and discovering new places with my bike in what just about 57 mins or so? And when I came back home they were like where u bin for so long? Whereas for me it had only felt like it was ten fifteen mins.

Do u understand where I'm coming from?

If you could travel at a much faster speed like speed of light speed or even faster, or even speed of light times speed of light speed and u travelled for about only five or ten mins and u came back to earth(if u're travelling at speed of light it'd take u about 8 and a half mins from eart to sun) your friends and family would have been aged. i.e your younger sister or brother would be much older than yourself, cuz u've only travelled ten mins, but actually in earth a lot of time has passed!

So I think it is possible to travel into the future.

what's your opinion???
