    Can a star be seen approaching a black hole forever?

    okay, that helps. thank you. and excuse me for my lack of knowledge under SR, i am really just getting into it and found this forum to be a great help

    Hydrogen atom to 90% the speed of light

    No. Yet the alien will perceive it that way, correct?

    Finite Universe: Light speed and the Earth's distance/time from event

    thank you! sorry, i am new and am not extremely aware as to how to find things yet, bu ti believe that will obviously help

    Does Poverty Stem from Laziness or Systemic Issues?

    Well i believe that there are those who had jobs and lost them due to the off shoring of jobs, and i would not consider them lazy. And then there are those who sit around waiting for their welfare check. Me? i believe that the latter one is the less predominate and that many poor people would...

    The morality of Science (or lack of)

    Why blame science for billions spent? That is nothing compared to the trillions spent on wars, or the amount of money spent on un-necessary goods. Why single out science? It is actually one thing that can help the rest of humanity and not just a select amount of people. If we can harness the...

    Can a star be seen approaching a black hole forever?

    So does the object approaching the speed of light actually become denser, or is that just relative to the static observer (still observer)? Therefore it is not actually becoming denser? Sorry for my lack of knowledge in SR

    *May be a stupid question* Does Oxygen/Nitrogen bend space-time?

    I understand that matter and energy bend space time, yet i am curious as to the level at which it requires to bend it. This is obviously an elementary leveled question, but i am quite curious. Also, is there any level of matter that is incapable of bending space-time? Thank you!

    Bacteria Space Travel: Does Speed Affect Cell Division?

    Well first, nothing can move at the speed of light so it wouldn't be possible. Second, time relatively stops at the speed of light so it is not applicable to record. Either way, time dilation would not affect this if you are traveling with the bacteria, and it would stay constant. From a...

    Is the speed of light constant

    It would not be the same observational point as one is moving. And either way, it is relative to the second observer that it is taking 1 second as he is already moving .5c

    Hydrogen atom to 90% the speed of light

    So atoms do not destabilize as a result of velocity? (i know i may sound stupid, just learning about Relativity and that good stuff)

    Is Spacetime Always Flat in Regions Without Mass?

    I thought space-time was curved only by matter and energy? In a vacuum space, would space-time be curved then?

    Why is the time dimension different from the 3 space dimensions

    Precisely :D You would have a 3D coordinate graph, along with a time aspect to it. It all works in the Mathematical background, yet i am not exactly the most knowledgeable on the topic tbh

    What if a black hole had a negative size ?

    To my knowledge, a black hole does not "suck everything in down to nothing". It merely takes the matter coming in through the event horizon and compresses it into a denser object and breaking down its fundamental particles, therefore increasing in mass (i believe).

    Finite Universe: Light speed and the Earth's distance/time from event

    This may not be the correct Forum to post this Thread, but i thought i might as well. I was just wondering: if the matter in the Universe is assumed to be 13.75 billions years old, why is it that we can witness things over 13.75 billion light years away? I came across this Wikipedia article on...
