True, due to our understanding of special relativity, SpaceTime is relative to the observer. Ergo, the speed of light is same within your speed of light (SOL) reference frame as it would be for someone who was traveling much slower. But then, what of Space? Yet this whole frame of reference for...
Per your understanding, "Now I understand! I didn't realize that everything around me would be moving at the same speed. That explains everything :) Thank you so much for explaining this. Now I can continue thinking more impractical questions that no one really care about! :D"
True, due to our...
PeterDonis - Per your question of why I would believe it would be possible for the twins to be of the same age when put back into the same frame of inertial reference. The concept of acceleration toward the speed of light puts the space traveling twin in a differing frame of reference. In order...
Tachyons are theoretical particles or waves that travel faster than the speed of light. Tachyons exist in a theoretical world where objects have negative mass. Negative mass is most easily define as a volume of negative density; i.e. -mass = volume * -density. Ergo negative mass density. This is...
Per your statement - "Teleportation, in the common SF sense of repositioning something from one place to another instantly, without passing through the intervening space." The concept of Time dilation still involves intervening space, or the relativity within the SpaceTime continuum.
In my...
PeterDonis - Since we are all talking theory anyway - While I appreciate the math behind the explanation of tidal forces within a black hole, there is more than just tidal forces to deal with. My statement was directed toward the reorganization of mass/matter within the accretion disk of a black...
Assuming the impossible, even though the Alcubierre drive does not directly violate the laws of physics, it does have difficulties that may be impossible to overcome. One such problem states that the only way such a transport system is possible is if, like a train, it followed a pre-set path...
Alright, working with your assumptions –
1. (I know this is impossible because we cannot create an infinite amount of energy but assume it is achievable)
2. So when a moving object reaches the speed of light time dilates so I assume if an object that has mass somehow achieves the speed of...
My take on you procedure is that it is fun science fiction - great imagination.
Per Question 1 assumption, ” If you go through the black hole, from your perspective then time will be fine, right?” You cannot go through a black hole. You can only go into a black hole. Perhaps you are confusing...
I am going to take a different approach to your question. Light travels at the speed of light because it is relatively massless (or zero mass) relative to the SpaceTime continuum. Therefore for anything to travel as faster or faster than the speed of light, it would need to be able to...
Per your query – “What I don't get is how do these objects move just because of a curve in the plane. Isn't this downward motion based upon the idea that gravity exists and is pulling it down? No matter how much you increase the slope, an object won't move if there isn't a force to move it (in...
Skipping the notion of velocity 0.5c (or half-light speed), in physics, the twin paradox is a fun thought experiment in special relativity involving identical twins, one of which makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has...
Maybe the thread owner should reconsider how to better phrase the question. Space (in and of itself) is a dimensional parameter of SpaceTime, which qualifies unbounded containment or abyss. Consequently it can be stated that Space is a form of infinity. There is no SpaceTime without Space and...
