Right, thank you. I just meant in the sense that it works against the pull of gravity. Am I on the right track assuming the magnetar would induce a magnetic repulsion on something like a chunk of carbon which would at least partially counteract the amount of gravity it feels? By analogy, in the...
If I'm interpreting you correctly, a magnetar has higher surface gravity than a non magnetar, all else being equal?
I remember experiments where normally non magnetic objects(like small animals) can be levitated using very powerful magnetic fields. Would a magnetar's magnetic field have a...
Probably a misguided question, but would the intense magnetic field of a magnetar increase the overall pull an object would feel at the surface of the magnetar as compared to a regular neutron star? Or would it possibly lessen the amount of gravitational pull the object would feel at the...
I was watching a video where Lawrence Krauss describes the big bang in terms of the observable universe. He says regions outside the observable universe need not have come from the big bang.

Hello. In the movie Interstellar with Matthew McConaughey, there is a scene where wormholes are being explained. The characters say that the wormhole passage is a passage way through 5 dimensional space. Also when they are going through the wormhole they say they are passing through the bulk...
I was watching Nova Science Now and they were talking about how stars form when gas clouds are compacted when hit by supernova shockwaves, which then allows them to compress further by their own gravity and eventually they ignite. But I was left wondering how then the first stars were able to...
Now I know the sun can't go supernova ever, but let's say the sun somehow acquires enough mass to eventually undergo a supernova with an energy output of one foe, what would happen to the solar system? Would the outer planets such as the gas giants and pluto survive?
Nope. Not schoolwork. I'm not in school. I'm just a guy who was curious about this particular question after reading some comics with giant super heroes. Immature I know. But I guess I'll try answering the question.
The guys initial volume is 6 cubic feet?
His mass is 86 kg.
So his density...
Let's say that we have a guy who is 6 feet tall and weighs 190 lb. If we were to make him 60 feet tall with the same proportions as before, how much would the man weigh? How much would he weigh if we make him 50 feet tall?
According to string theory there are an extra 7 spatial dimensions curled up at every point in space. They are so small(Planck length) that nothing can move through them and are completely undetectable. My question is this:
Does string theory allow for these dimensions to uncurl and become...
I have a question. In an electric arc, the electric current going through the air makes a visible plasma arc as so:

My question is this: Could a high power laser create a visible plasma channel through its path. I ask...
