Can anyone tell me if there is a planetarium program on the net that could find all the variable stars of declination 70degrees N and brighter than mag...

I am after suggestions for worthwhile photometry projects with high northern declination (60degreesN) and relatively bright (brighter than 6.0mag). I suffer...

from someone with an interest but no education in this area. If the universe is expanding, doesn't that mean that there is a boundary to what scientists define...

This paper has proposed a theoretical idea to construct particles by using electron, positron, neutrino and anti-neutrino as well as the weak force interaction...

Is it possible that a sufficiently strong magnetic field will distort spacetime? (acting the same way as an extremely massive object)

The fossil record shows that evolution has not progressed uniformly. From time to time short duration events caused mass extinctions. The usual explanation...

Part 1 Mystery 1 Most small asteroids have an angular momentum (at least I am not aware of one that doesn't). The instantaneous rotation axis goes through the...

These questions are strictly hypothetical. Question 1. If the earth expanded at the same rate as the universe, how much would the radius increase in 1 million...

I would like to state my questions in plain english, but I am more comfortable adding simple (high school) equations. A function of time can be expressed as...

In my opinion the two slit experiment validates the string theory. It also provides evidence for the existence of space filling 3-branes. (for a discussion of...

In the standard model inflation usually refers to the period of time when space expanded at a rate that exceeded the speed of light. The usual explanation...
