An outside light we have used to cause a 'trip out' sometimes if it rained. I could find no sign of water ingress, so for safety I put the coach light on a two pole isolator breaker circuit. I also fitted an energy saving bulb. I then began to notice, when isolated, the light would flash on and off, about twice a second, but this decreased in frequency (the event) and eventually stoped.

Then after a gap of some months I noticed the same effect in our hallway, again a neon type bulb. When the switch is in the off position the bulb flashes dimly.

In reaching for the bulb to take it out, and before actually touching it, I was puzzled to find the light continues to flash, but at nearly full brightness. Withdraw the hand and the flashing again becomes very dim.

What is happening? Is this the AC somehow still making a circuit, (with the switch off yet somehow earthing), or is static involved? What is my hand doing to the bulb (or the bulb doing to my hand for that matter)?

Einstein has proposed that the universe is comprised of various seperate universes called the "multiverse." Each of these dimensions parallel our own with different events in history having different outcomes. Yet the physical universe is the same.

At the same time, Hawkins has proposed that there is an actual, real 4th dimension that exists around all of us, but we can not sense it at all except that passing of time and memories. This 4th dimension consists of time and space itself.

So my question is, is the 4th dimension in the same vein as a parallel dimension?

At t = 0, an object is projected with a speed v0 = 45 m/s at an angle q0 = 30.4° above the horizontal. The axes on the diagram show the x and y directions that are to be considered positive.
its horizontal velocity is 38.81m/s
at t = 10 s

If two clocks were calibrated for accuracy, then one clock was moved from one level of gravity to another, eg earth to moon would it measure time at the same rate in relationship to the other clock?

if my location is 1150 feet above sea level

most of the surrounding towns and cities are at about 1000-1200 feet above sea level.

my geography around me is hilly.

my antenna is 50 feet above the ground and is 22 feet tall, it is an omnidirectional antenna.

i beleive the entire 22 feet radiates the R.F.

i am transmitting at 28.555mhz with a 150 watt deadkey and1000 peak @ 90% modulation

not counting for skipping off the ionsphere ( no skip)

how far away theroetically, could the signal be recived by a similar station.

how about the antenna at 70' which should be right at a 2 wavelengths which would be ideal.

i hope i have included enough info

atoms are made up of 99% empty space, and we’re made up of atoms, so we must be made up of 99% empty space... how is this possible??

we had lab in school for free fall object. In the lab, all group had gravity of b/w 9.00 to 9.74 instead of 9.81.
if the human error and air resistance is neglected then why is the gravity is different by few %.????????

I'm no scientist, but from what I understand, a microwave works by stimulating the molecules to move about quicker, hence creating the heat necessary to warm whatever's in side. Now, when things get cold, it's because the molecules have slowed, right? So, we have a microwave, why isn't there a device to slow molecules rapidly, thus creating a device to cool things, even freeze things, in seconds/minutes?

Is this Einstein the speed of light which he postulated?
The speed of light ; C^2=Acceleration on earth's surface times 1/3 divided by the mass curvature.

Does that mean that C^2 isdirectly proportional to gravity field and
inverserly proportional to the curvature of the gravitational mass? is this a new discovery?
