Yes Thankyou

I need some information on Flourescent microscopi.

Then wouldn't the universe's rate of expansion eventually surpass the speed of light?

I don't see why we couldn't genetically engineer viruses to have correct DNA. And use them to replace or fix the corrupt DNA in cancer cells.

But the universe is accelerating with its expansion. right?

If the universe is forever expanding and forever accelerating. Then there would be a point at which the velocity of the expansion of the universe would surpass the speed of light; at that point the arrow of time would be reversed. Would the Universe then retract???

So then we are seeing 2d objects that our brain is programmed to precieve as 3d.

What makes you so sure that the universe will expand forever?

How fast is the universe expanding?

Would these other universes be some what parallel

It is impossible to precieve what is beyond the edge of the universe being that we can not observe and nothing can exist beyond the universe, beyond space and time.

I have heard that there are intervals of time in which nothing can occur, but if nothing can happen in those intervals then how can many of those intervals lead to any thing?

Can someone tell me what the origin of zerois???

It is Universally accepted that time is the manifestation of the fourth dimension. Even so Have you ever seen a 4-dimensional figure? Can a 3-dimensional figure move without time? Can a

2-dimensional figure move without time?

I am proposing that time is not the fourth dimension, but a binding law that all dimensions must obey.

Tell me what you think.

Too many Paradoxes, not possible

At the American Physical Society Spring Meeting in Washington, D.C. on Monday, Tod Strohmayer of NASA's Goddard Space Flight Center presented concrete evidence that some black holes actually spin as they suck in their surroundings. "Almost every kind of object in space spins, such as planets, stars and galaxies," he says. "With black holes, it's much harder to directly see that they are spinning, because they don't have a solid surface that you can watch spin around." But he proved his case nevertheless using data from NASA's Rossi X-ray Timing Explorer Satellite. Strohmayer looked at GRO J1655-40, a microquasar black hole about 10,000 light years from earth. Jets of high-speed particles shoot straight up and down from this type of black hole (see image). And among the emanations, Strohmayer noticed two distinct patterns of flickering x-rays known as quasiperiodic oscillations, or QPOs—one previously detected QPO at 300 Hertz (Hz) and a new one at 450 Hz. Scientists had only ever detected this sort of radiation around spinning neutron stars.

The QPO at 450 Hz presented a puzzle. From it, Strohmayer calculated that GRO J1655-40's innermost stable orbit—the closest anything can circle the black hole without falling in-should be 49 kilometers or less. And yet based on the black hole's mass, estimated to be seven times greater than that of the sun, the innermost stable orbit should be 64 kilometers. The only way to resolve the contradiction, Strohmayer says, is if GRO J1655-40 spins: "A spinning black hole modifies the fabric of spacetime near it. The spinning allows matter to orbit at a closer distance than if it were not spinning, and the closer matter can get the faster it can orbit. For GRO J1655-40 we can now say that the only way for it to produce the 450 Hz QPO is if it is spinning." --Harald Franzen

Time travel is very possible. Every second of every day we are traveling to another point time. But to describe motion in a certain dimension you need the dimension above it and everyone below it. For example speed is always described as

unit of length/elementary unit of time, so motion through time must be described as

unit of time\unit of the manifestation of the 5th dimension

consequently, To understand time travel we must understand 5th dimensional space.
