    Is there life in the universe, and if so has it visited Earth?

    I just find it rather unusual how so many people would call in for the same things. UFOs? If you're going to prank call, which I would have to say some of the UFO reports are, why report a UFO? Also, there's the whole Roswell incident, which is very fishy, if you ask me.

    Graduate Is space warped, or is matter expanding?

    What I'm trying to say is that it should be fundamentally the same, if matter is expanding or if space is warped. However, if matter is expanding, it is the expansion that causes gravity. When two particles grow at the same rate, the space between them decreases by a square root, the same as...

    Graduate Is space warped, or is matter expanding?

    But due to the second law of thermodynamics, matter should still expand, correct? It is trying to reach equilibrium.

    Graduate Is space warped, or is matter expanding?

    Why do physicists say that space is warped in with the presence of mass? Wasn't the whole concept of spatial coordinates supposed to make measuring distance easier? I think it would be easier to say that matter expands outwards in the presence of space. Also, because of the second law of...

    Undergrad What are the types of waves that can travel through space?

    I know there are different types of waves in matter, for example P waves, S waves, etc. But do these correlate to waves in space? For example I know of two types of waves through space: gravitational waves and light waves, which both travel at precisely the same speed. Are there any more...

    Graduate Why doesn't the electron fall into the nucleus?

    I only use the analogy to explain the effects of inertia on the electron. Only a loss of energy ( in the form of heat ) can bring the electron closer to the nucleus. There is obviously no friction in subatomic space, so there is no other reason that the electron would lose energy.

    Graduate Are black holes bosons or fermions?

    A black hole would be a fermion because it is made of matter. Bosons are generally force carriers, so this means that black holes emit fermions (gravitons). I'm pretty sure I'm right here, but please tell me if I'm wrong...I'm learning too!

    Graduate Why doesn't the electron fall into the nucleus?

    This is similar to the question to the question: "Why doesn't the Earth fall into the Sun?". In both, the answer is that the revolving object has enough inertia to prevent it. Also, there is a confusion over quantum physics. While we hold Heisenberg's uncertainty principle to be true, this...

    High School Gravity & State of Matter: Does Force Vary?

    No, only matter is affected. Gravity could be thought of as a type of energy, but a force is simply a perpetual energy exerter.

    Graduate Is Time Truly a Uni-Dimensional Force?

    You can measure time in a 3D and a 2D world. In fact, a flatland would be three dimensional since it includes time as a dimension. You just cannot measure a higher spacial dimension. Also I bolded the circular reasoning (it's unscientific).

    High School Why can't electromagnetic radiation escape black holes?

    The biggest reason for which light cannot escape a black hole is the fact that the black hole bends space. Light always travels in a straight line in relation to space, so if the space is curved, then light will curve with it. Light is simply following the curved space into the black hole...

    Undergrad A copernicus/relativity question

    You could say that the Earth is at rest, and according to General Relativity you would be correct. However you need to explain the movements of the rest of the planets as well, too then. This didn't go well for the church... Also, this relativistic moving is not effected by curves in...
