Virtual Trips to
Black Holes and Neutron Stars
by Robert Nemiroff (Michigan Technological University)

Ever wonder what it would look like to travel to a black hole? A neutron star? If so, you might find this page interesting. Here you will find descriptions and MPEG movies that take you on such exciting trips. These movies are scientifically accurate computer animations made with strict adherence to Einstein's General Theory of Relativity. The descriptions are written to be understandable on a variety of levels - from the casually curious to the professionally inquisitive. It is hoped that students from grade school to graduate school will find these virtual trips educational.

"A stimulating, relativistically accurate trip!"
- Kip Thorne
The Feynman Professor of Theoretical Physics, California Institute of Technology, Author of "Black Holes and Time Warps - Einstein's Outrageous Legacy"

Written Description of Visible Distortion Effects
Below is a published paper understandable to undergraduates: "Visual Distortions Near a Black Hole and Neutron Star," Nemiroff, R. J. 1993, American Journal of Physics, 61, 619

* Introduction
* Gravitational Principles and Mathematics
* General Description of Visual Distortion Effects
* Neutron Star Trip Description with GIFs
* Black Hole Trip Description with GIFs
* Ultracompact Neutron Star Trip Description with GIFs
* Appendix: A simply stated problem (and solution)
* References

* Complete postscript text
* Postscript Figure 3d

Information and software on MPEG players are freely available from other sites.

Fantasy MPEG movie to a black hole
Gravity causes stars to have multiple images. Two images of the constellation of Orion are particularly apparent.

* Approaching the black hole. (182 k; explanation)
* Circling the black hole at some distance. (819 k; explanation)
* Approaching the photon sphere. (140 k; explanation)
* Looking up at the photon sphere. (46 k; explanation)
* Circling the black hole at the photon sphere. (452 k; explanation)

Still curious about black hole properties? Here Matt McIrvin answered some frequently asked questions about black holes to the internet newsgroup sci.physics.

Fantasy MPEG movie to a neutron star
The surface of the Earth has been mapped onto the neutron star to better allow the observer to follow the visual distortion effects caused by the high gravitational field.

* Approaching the neutron star. (147 k; fun)
* Circling the neutron star at some distance. (898 k; fun +)
* Landing on the neutron stars surface. (168 k; OK)
* Looking north on the neutron star's surface. (44 k; OK)
* Circling the neutron star just above its surface. (563 k; fun ++)

Fantasy MPEG movie to an ultracompact star
Note the color changes for the stars and surface as they get redshifted and blueshifted. The constellation Orion is visible in most sequences - can you find it?

* Approaching the ultracompact star. (196 k; fun)
* Circling the ultracompact star. (913 k; fun +)
* Descending to the photon sphere. (220 k; OK)
* Looking up at the photon sphere. (140 k; OK)
* Circling the ultracompact star at the photon sphere. (732 k; fun +)
* Descending to the ultracompact star's surface. (135 k; OK)
* Surveying the surface. (216 k; fun)
* Circling the ultracompact star just above the surface. (627 k; best movie)

[FluorescentArmy]

The unsaid tone of weak despair
fail to resonate
frayed ends of our binding threads
will disintegrate

By laws our physique state
failure to communicate

None too sentient
Hear no, see no works its magic
Against all function

Ongoing choices
the trials will end
filter the nonsense
and laugh at what’s left
Indecision/non vision
what matters taken away

Look at the shell that is you
Empty, fragile, weak
Soon the battle is over
Lost to Apathy

So overcome with pointless tears
to test pain receptors
nothing matters ever here
put up a non reaction

These eyes will never see
covered up from reality

Look at the shell that is you
Empty, fragile, weak
Soon this battle is over
Lost to Apathy

The unknown world that you deny
no priority
Cannot fail if you never start
How predictable

I want to know
Where did it end?
for madness to start
Always the sceptic
Never be part
Introvertive /non descriptive
It matters not

Look at the shell that is you
Empty, fragile, weak
Soon this battle is over
Lost to Apathy

this is a pretty accurate title for every thread in this forum

The game forum has legitimate games and purposeful threads. Hell, I LOVED the count-up thread. And while I don't care for 1mil get, it's most appropriate here.

Postwhoring without purpose, though, is unacceptable.

Depends on my mood.

My mood is perpetually irate.

It's not the intended purpose.

It's just how everything turns out in the end.

I never take this forum seriously. Nobody does.
