Which of these concepts do u think is possible?
View attachment 62301
1)speed yes,speed influence time,greater the speed greater would be time dilation,theory of special relativity, time dilation through speed.when we can travel through the speed of light or more may be in a century or so if tech advances and if a toy is made in which we can sit and travel faster than or at speed of light ,it’s more possible than today.
2)Gravity yes.The greater the mass of an planetary object the greater the gravitational force.
The greater the gravitational force the greater would be time dilation.
theory of general relativity,time dilation through strong gravitational force which can bend the space time plane even so much so that ,object or planet disrupts/pierce the plane and go through it even resulting in warm hole and great amount of time dilation.
3)warmhole yes. 4)black hole yes
If an atom like warmhole(as per a bald nobel prize physicist who helped christhoper nolan through theories in interstellar movie keeping the main crux scientifically bonafide))if can be kept open and expanded and exposed through strong negative energy and if we go through it ,time dilation would be much,
how to harvest such energy can be given a thought.
Such enormous amount of energy a spinning black hole is easily capable to give for free.
and what to speak of the energy at the centre of black hole in which the time dilation can go beyond imagination or infinity.
if one can even come back from such ever fascinating scary holes going closer ,again speculative.
Better to stay away from such holes and focus on other kind of hole
Can be good time to watch intersteller again tonight for me.
