Do Black Holes and Wormholes Affect Time and Space Similarly?

Click For Summary

Discussion Overview

The discussion explores the effects of black holes and wormholes on time and space, particularly focusing on whether they influence time similarly. Participants examine theoretical implications, gravitational effects, and the nature of time dilation in the context of black holes and wormholes.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether time slows down as a black hole approaches, noting the strong gravitational field of black holes and the implications of Hawking radiation.
  • Another participant discusses the relative nature of time, suggesting that time slows down for an object moving towards a black hole, but this effect is only observable from an outside perspective.
  • There is a mention of wormholes having a different gravitational effect compared to black holes, with some participants proposing that wormholes attract gravitationally but not as strongly as black holes.
  • Hawking radiation is described as a phenomenon that allows light to escape from near the event horizon, raising questions about the nature of time and gravity in relation to black holes.
  • Participants express uncertainty about the concept of a universal time, suggesting that time is not consistent across different frames of reference in the universe.

Areas of Agreement / Disagreement

Participants express differing views on the nature of time dilation related to black holes and the effects of wormholes, indicating that multiple competing perspectives exist without consensus on the specifics of these phenomena.

Contextual Notes

Discussions include assumptions about gravitational effects, the nature of time, and the theoretical framework surrounding black holes and wormholes, which remain unresolved and dependent on interpretations of physics.

[SOLVED] Black Holes vs wormholes

when a planet has a black hole outside its orbit. and you were on the surface. would time slow down as the black hole gets closer? because the black hole is pulling everything towards it. i know nothing can escape a black hole, not even light. As we know wormholes are theorectical, we can predict the motion, speed and velocity by giving examples using laws of physics. do wormholes pull things towards it as like a black hole or is it totally different effect ( speaking theoreactlly)? any laws of physics showing the calculations of examples by how much time would slow down with the current data known of black holes would be much apprecated.

Where is the object you wish to measure time relative to - towards the hole, or away from it? The denser (or more attenuated) intervening spacetime becomes, the longer (or shorter) the interval of time elapsed. Light can, by quantum effect, escape the horizon of the black hole by a process called Hawking radiation. Wormholes, having progressively reduced curvature at first, do attract gravitationally with their cylindrical symmetry, but not as greatly as the spherically collapsed black hole.
 
when an object is going towards it, time must slow down some way. i thought a black hole's gravtational field was so strong nothing could escape it? does hawking's radiation prove that light can escape from the event horizon?.

Hawking radiation makes black holes glow slightly with photons, neutrinos, and other massive particles.

This is due to virtual particle pairs being created near the event horizon of the black hole. This happens everywhere as particle-antiparticle pairs, which upon creation annihilate each other; although, near the event horizon it is possible for one to fall in before annihilation and the other particle to escape, as Hawking radiation.

This does mean light escapes from the event horizon, part of it, although the hawking radiation never actually enters the event horizon. Hawking radiation also allows for black holes to lose mass, and possibly 'evaporate' (or decay).

Time slows down as the black hole approaches, or you approach the black hole, only relative to you, as viewed by an outside observer. You would notice no time change. If you entered the black hole and stayed for 10 years, and then exited the black hole, then you would have only aged 10 years, whereas everybody 'outside' of the black hole would have aged more then 10 years.

You seem to think there is a 'universal' time everywhere in the universe by which "TIME" is gauged, this is not so.
