There is no consensus on climate change. Much of what Al Gore said has been debunked because there is so much fraud behind it. This is not to say we have not had warm periods. It's too complex a science with lots of feedback loops than to blame a gas that occupies only 0.038% of the...

Every so often they revise Hubble's constant to ensure that they have the age of the universe right. They believe now 13.7GA. What is know about our solar system is that its moving toward the Hercules constellar. The next North Star is expected to be Vega in Lyra.

Well in the cosmos, light is traveling largely in a vacuum. We are in the era of a mass-deficient universe but energy strong universe. Oh but there lots of galaxies out there-that is a lot of mass but they moving away. Of course once light hits something like a planet-it may be reflected...

We don't have a perfect theory on moon formation but the accepted one is some great object slammed into earth & that was the debris blown out. Other theory has to do with simultaneous formation with the earth-they do share a lot of the same materials.

We know that the classic cliche in any astronomy class Is this: "Stardust we are born & to stardust we return." Indeed supernovas made much of the heavier, complex stuff. But yes the basic star forms a lot of the elements. There's also a lot of the other interstellar objects...an array of...

I have an M.S. in earth science & enjoyed astrophysics. It's a very doable course mathwise.

Correction. Objects very very far away appear to move slowly if at all. When we gaze at stars they appear in fixed positions in the sky yet they are moving & of course we are moving in our orbit & our solar system is rotating in our greater galaxy which is also moving. When we say the...

What it means is that the fabric of space is expanding. Individual stars contract & expand depending on their metabolic processes. Galaxies can collide because they are moving thru space & attracted by gravity. Inside a galaxy, there may or may not be new stellar nurseries-depends on the type...

Thanks to the internet you can find a lot of material on the science details right from the web. Suggestions: spacetime & how they are one & the same. Types of supernovas & how some stars will nova & some will not b/c it all depends on their dna. Black hole regions. Specific types of stars...

Good question because the term planet became associated just wi/in our solary system until we began locating planets in other stellar systems. The reason for the reclassification is because Pluto is not quite like the terrestrial planets which are the interior planets known for their...

The universe is infinite. It has no edge so you can not measure something that is infinite. Theory goes & no we cannot grapple this, it began from a point of singularity & exploded in a shock wave. It transformed from a mass-dominated/energy deficient to a energy dominated/mass insufficient...
