    What happens to density as speed increases?

    Sorry, I was in a rush when I wrote this. I meant if you were an external observer measuring the density of the ship. Does this also work backwards in the sense that if you are on this ship and measure the density of an object going much slower, is its density lighter? Ultimately what I'm...

    What happens to density as speed increases?

    Assuming a ship is approaching the speed of light, what happens to its density? Is there any notable change at all?

    Evidence of inexistence in black holes?

    Yes, timespace should have been spacetime. My bad. By negative index, I was essentially referring to what has already been stated: time running backwards. Not necessarily a white hole, but a reverse in time outside relative to yourself. And I'm only just realizing that testing this would be...

    Evidence of inexistence in black holes?

    Is there any hard evidence that the inside of a black hole is simply an empty oblivion of nothingness? I've been mulling over some thoughts on time, and this has been grinding progress. I'm currently trying to find if the possibility of its center being a negative index of timespace is indeed...

    How long to reach the speed of light?

    Whoops, my mistake. :redface: Well, the number wasn't exactly 99.99. It was something along the lines of 99.996 with a bunch of trailing numbers. We were told to round to the thousandths, though why I did it to the hundredths in some of these I cannot remember. Probably related to the fact...

    How long to reach the speed of light?

    An uninhibited, constant acceleration produced by what I can assume to be rockets, thrusters, or space-gnomes blowing into external sails really hard. But seriously, we were just told a constant acceleration of 9.80665 m/s that is never affected (slowed, skewed, or otherwise manipulated off...

    How long to reach the speed of light?

    Homework Statement Assuming you are traveling at 9.80665 m/s in space, how long would it take to reach light-speed? My teacher told us the question was in-part a trick; we can never truly reach the speed of light, only get very close. She told us to simply give the percentage of the speed...

    Can wormholes be used for faster-than-light travel?

    Okay, I'm trying to get a grasp of how exactly wormholes function, how they form, etc. Please correct any and all flaws/mistakes in my understanding and further educate me, if you please. :) A wormhole could, theoretically, span any distance. Though the greater the distance (relative to our...
