mass is almost weight less the effect of near field gravity

Ok, are they trying to create a black hole in the hedron collider ?

think of it as the space between the atoms shrinks...the denser something is, the less space there is between the atoms... if the earth shrunk to the size of a peanut, and retained it's mass, that's kind of what a black whole would be

Weight is not mass. Weight is the rate of gravity upon mass.
The mass would not change on the moon. Only the effect of gravity on it would change.


Not sure but I think they did that a few years ago.
Tiny black holes that evaporate as quickly as they form.
Thing is, what they are calling black holes may not be black holes but something else. Perhaps black holes as in pockets of emptiness?

my understanding to is the mass only drops if sub atomic particles are destroyed during the fission. otherwise it's just re-arranged into different atoms. u235 is split into other lighter materials but total mass of byproducts is same.

mind you i'm dredging this up from 30 plus years ago helping the nuke guys to study in aschool

So if the moon developed a really strong gravity for some reason would it shrink visually?

In a way, yes.
Fission does release energy with loss of mass.
A black hole is not a fission reactor. It fuses matter, in essence two atoms are forced to occupy the same space. The mass increases.
The heat that is created under such extreme pressures is like at the other end of the scale from fission heat.


Lets say a tiny chunk of neutron star were embedded into the moon and stop (not likely but for all intentions of discussion).
Not only would the neutron star matter pull all the moon's matter towards it, thereby shrinking the moon. It would also cause gravity issues on Earth. Depending on the amount of mass in question, the Earth could slowly spiral onto the moon. Likely our atmosphere first followed by our water and eventually the dirt and rock. All the while the Earth would be moving closer to the moon.

It would also affect the orbits of all the material in the solar system, including the distance of the Sun. With enough mass, the moon could pull all the matter in the solar system to it creating a new star with much higher mass.

Well that would be the end of us but would be cool to see!

LOL, we will be ended way, way before that.
Plus at that point of true balance there will be no light because nothing will emit photons. You really wouldn't "see" anything.

does that mean if they got close to a black hole they couldn't see inside?

Mikey, the event horizon is commonly a point where light cannot escape the gravity of a singularity. (There are other event horizons.)
To see or detect anything, something must strike the eye or detector. If nothing does, you can't see it.
Light is captured. It moves towards the singularity not outward toward your eye. There is nothing striking your eye to register an image to your brain.
No photons can escape the gravity, thus, in a balanced Universe of dead black holes, even if there is light it can't escape to hit your eye. You see only darkness or absence of photons. Your eyes may still work but there would be nothing sending image signals to your brain.
