comment What current evidence is there that disproves the Big Bang Theory?
The Big Bang happened everywhere -- but would it be accurate to say that the matter making up the currently observable universe expanded from an arbitrarily small volume? For example, the volume and mass currently making up the Milky way might have occupied, say, one cubic meter shortly after the Big Bang, and one millimeter before that, and so on.

comment What current evidence is there that disproves the Big Bang Theory?
If the estimated age of the Universe varies from book to book, you're probably reading some old books. Books published recently should, I expect, be reasonably consistent in giving an estimate very close to 13.8 billion years. What is the most recent book you've seen that gives an estimate outside, say, the range 13.7 to 13.9 billion years? Also, your question would be better if it were just a question. You state as a fact that "There is current evidence in our solar system that disproves this theory". There really isn't.

comment Birthdate differences calculation relative to earths orbit duration
Yes, but the birth dates were expressed in calendar days. I've added a comment asking for clarification.

comment Birthdate differences calculation relative to earths orbit duration
It's not clear (to me, at least) just what you mean by "the real difference in our birthdates ... relation to how long earth orbits around sun". Are you trying to express the difference in sidereal years? If so, I'll delete my answer.

comment Birthdate differences calculation relative to earths orbit duration
The dates given are calendar dates, and there are no intervening leap days, so the 6 hours and 9 minutes doesn't apply. And by simplifying the question, you're not really answering it. If two people are born on the same calendar date and time in 1983 and 1984, then their ages differ by exactly 365 or 366 days, depending on whether the leap day 1984-02-29 is between their birth dates.

comment Multiple apparent lunar eclipses last night
So something was blocking the moon as seen from your location. How sharp was the edge of the blockage? Was the edge straight or curved? (I can just about guarantee it wasn't a true eclipse; almost certainly something close to you, within a few miles, was blocking your view.)

comment How to polar align an equatorial mounted telescope when you are close to the equator?
Sounds like you need to figure out where due north is and aim about 4° below the top of the mountains. If I knew a good way to do that I'd post an answer, but a compass, a level, and a protractor might help. (Polaris is about 1° off the celestial north pole anyway.)

Polaris should be 16° above the northern horizon.

comment Connection between Earth, Moon, Theia, and astroid belt?
I'm saying that if a body the size of Ceres were deformed into some non-spherical shape, it would re-form itself into a sphere over time. Any significant irregularities would not hold up against gravity. We have at least one Hubble photo showing it to be close to spherical; this is not a coincidence. I don't suggest that it's plausible that Ceres is a remnant of the Theia/Earth collision, but its shape doesn't argue against it.

I don't think the shape of Ceres is an issue. It's big enough for its own gravity to pull it into a sphere.

comment What would the effects be on Earth if Jupiter was turned into a star?
And I'm pretty sure Lucifer's energy output was far less than the Sun's, so the increase would be even smaller.

comment What would the effects be on Earth if Jupiter was turned into a star?
@HDE226868: I believe the monoliths compressed Jupiter; they didn't appear to add mass (that's certainly what it looked like in the movie). The Sun supports fusion because its core is sufficiently dense, because it has all that mass compressing it gravitationally. Assuming Jupiter's core is mostly hydrogen, it should also support fusion given enough density/pressure, whether that pressure is applied by gravity or by "sufficiently advanced technology" (a.k.a. magic). I don't know whether continuing intervention would be needed to keep it from re-expanding.

comment What is the farthest point of light that is emitted by a torch?
In US English, a handheld battery-powered light is called a "flashlight"; the word "torch" usually refers to a more primitive burning light source.

comment What would happen if an ice cube is left in space?
In the Oort cloud, I don't think there's a whole lot of gas and other objects for it to pick up (though we probably don't have a good estimate for its density).

comment What's the likelihood of the existence of unknown elements in the Solar System?
Elements in the "island of stability" are expected to be relatively stable, compared to their neighbors. Quoting the Wikipedia article, "Specifically, they are expected to have radioactive decay half-lives of minutes or days, with "some optimists" expecting half-lives of millions of years." Even with half lives in the millions of years, there could still have gone through hundreds or thousands of half-lives over the history of the Solar System. Unless the optimists are underestimating their stability, there should be practically nothing left of them.
