When I was a senior in high school, I got home from basketball practice one evening and no one else was home. I was walking around outside and the atmosphere, the wind, the leaves rustling at my feet, the fire orange-and-purple sky as the sun set... it was all so moody. I came inside after walking for a while and the…

"v = 12mi/sec = 19km/sec = 1.9e3km/sec"

eh?

Technically, the answer to your question is yes, as even the smallest mass can affect the earth's orbit. Practically though, no, there wouldn't have been much of a change.

The earth weighs about 6E24 kg and is moving, relative to the sun, at ~30,000 m/s for a momentum of about 18E28 newton seconds. The asteroid…

karate chopping or sticking a knife in the bottle while turned on its side. Either one.

Would like to see the results of a frozen non-polar solvent bullet in the ballistic gel, as the surface molecular forces might be less prohibitive for penetration. For example, solid chloroform, which should be more dense than solid water, and the Van der Waals forces will be less on its way into the gel. It will…

How big a chunk of neutronium would you need for the gravity of that chunk to keep the exploding force of degeneracy pressure at bay?

Nice IWC

Turtles, all the way down.

The rapidly alternating electrical field in the coil Coulombically induces a current in each atom of the aluminum chunk, and then this current of course will produce a magnetic field which is opposite that of the induced magnetic field (from the current) of the coil... and levitation. (The induced current makes the…

The narration is very non-Mennonite.

I maintain some skepticism, too.

It has a more "organic-y" look to me than water. Also, they're using a mass spec solvent... which can be water, but is also sometimes methanol, chloroform, or dichloromethane.

One thing I just thought about: if you had a table or surface sufficiently strong to rest the sugar cube size neutron star piece on, it would sit there making a big "sucking" sound and cause a pretty good breeze toward itself because it'd be sucking in atmosphere like nobody's business. And it can compactify whatever…

Condensation, or density, of mass does nothing to affect the gravitational force. Earth at its present size versus earth compressed to 1 meter wide: still the same gravitational force versus your distance from ITS CENTER.

sugarcube of neutron star weighs 400 million metric tons, or 400 billion kg. You weigh 100 kg. You are standing 0.1 meters from the sugarcube.
F= G (m1*m2/r*r),
G=6.6E-11
m1=400E9
m2=100
r=0.1

F= roughly 266800 newtons

By comparison, 100 kg you feels 980 newtons force from earth's pull, feeling like "1 gee". So you'd feel…

*inversely proportional

No. If a sugar cube of neutron star weighs 400 million metric tons, or 400 billion kg, the earth already weighs 6 billion billion million kilograms. So a sugar cube of neutron star isn't going to collapse the much, much heavier planet in on itself. If you weigh 100 kg, the force you feel at 1 m from the sugar cube of…

Carl Sagan wrote about what would happen if you dropped a teaspoonful of neutron star on Earth in "Cosmos." Sort of a Swiss cheese, oscillate from surface to surface coming to rest at the center sort of thing. Also the density he gave (as well as Wikipedia!), and thus theoretical mass of a sugar cube sized dollop of…

I demand a recunt.
