Wormholes expeling particles at superluminal speeds

AI Thread Summary
The discussion explores the theoretical possibility of particles traveling faster than light through wormholes, particularly in relation to the universe's expansion. It raises questions about whether particles could "ride" the wavefront of this expansion and enter a wormhole, potentially exiting at superluminal speeds. Participants debate the implications of such travel on time perception, suggesting that it could lead to backward time travel relative to the rest of the universe. There is also a mention of the gravitational field's role in this context and the concept of antigravity materials enabling wormhole creation. Overall, the conversation remains speculative, with participants open to corrections and further clarification.

Probably a crazy idea but perhaps possible, so let me ask...

GR doesn't prevent particles, even those with mass, to travel at speeds higher than the maximal speed of light (C), if that was their initial speed.

Now, the only thing traveling faster than C is expansion of our Universe.

First, are there also particles 'riding' that wavefront?

Second, if so, what if one end of a wormhole would appear in that region and the other somewhere inside the Universe, might it be possible that the particle riding that wavefront at speeds exceeding C enters that wormhole and then exits it inside Universe, perhaps even near Earth, and keep that speed?

Third, would such a particle 'experience' (not in regard of itself, but in regard of Universe) traveling backwards in time ending in a Big Bang, while time still goes forward for the rest of Universe?

I believe the wavefront of the universe is the gravitational field of the universe's total mass. So therefore it might be gravitons or so. But I am happy if someone would correct me.

Second

No. The universe travels faster than c from our perspective but if you were on the "edge", it would be below c. So speed depends on the position in space and at no point in universe you can exceed the speed c. This might have to do with the quantum changes in materia and how "long" it takes to change energy states within that materia.

Again, I would be happy if anyone would correct me.

Third

I think what you are talking about is material with antigravity. I that case you could build a wormwhole in spacetime, and, as universe expands on any place, you could fold it in a way that you travel backwards in time.

Again, I'd be happy for corrections/clarifications.

Heh, that would polarize things here even more. :wink:
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
