Can A 'Distant' Quasar Lie Within A Nearby Galaxy?

How could a galaxy 300 million light years away contain a stellar object several billion light years away?

That's an easy one - wormholes exist. We're just viewing that quasar through a wormhole lens that happens to lie in the 300 million light year away galaxy.

Ignore the wormhole comment above. The writer has no idea what he is talking about

The physicists are men a thousand times more intelligent than you or I.

This is the only thing about your reply that I cannot let pass.

They may be a 1000 times more experienced in this field than you or I, but they are no more, nor no less intelligent than anyone else.

Stephen Hawking is considered a mental giant,but that is because his mind has nothing else to do or distract it. FOCUS is a very essential component of achievement.

I remember a science teacher a long time ago saying that nothing could travel faster than the speed of light.Was he correct or mistaken?

Correct.

[UCANSEE2]

Theory says nothing can move faster than the speed of light.

There may be elements of the universe that can travel faster than the speed of light, but our current theory does not allow acceptance of their existence, if they do.

[UCANSEE2]

Wasn't it Einstein who made a remark very similar to this?

[PatrickHenry]

There may be elements of the universe that can travel faster than the speed of light, but our current theory does not allow acceptance of their existence, if they do.

Yeah, bummer.

[EternalVigilance]

I don't know. Could well be.

"If I am not mistaken, discoveries like this one are calling the entire Big Bang hypothesis in question."

This and Dark Matter do put some wrenches in the system. I still think the Earth is a tad older than 6,000 years though.

[UCANSEE2]

The wisest man is the one who realizes how little he knows..

And conversely,

Those who know very little, seem to think they know everything.

I thought the Big Bang was the creation of some female porno star in LA.

Red shift measurements do not come from known brightnesses, but rather looking at the spectrum of light coming from the source. Certain lines of brightness should be at a specific frequency.. the line for hydrogen lets say. It is said to be red shifted when its frequency is lower than expected.. "redder"

This is akin to the sound that you hear when a train passes by.. The tone of the whistle gets lower as well as all of the other sounds at they recede from you..

You would only notice red shifting of headlights visually if you were going very very fast.. lets say perhaps 10,000 miles per second or better.. but then again.. you would be vaporizing due to the air resistance. But it wouldn't be red shifting.. you would see a blue tinge because you would be blue shifting when you were approaching.) The red tail lights receding would go dim or seemingly go out.. as the observed light would be tending toward the infrared.

Needless to say, this is slightly faster than the posted speed limits.

Hmmm...I see you've never seen Chicago cabs in between stoplights...

My first thought - relative to skip on am radio. Skipping through time via a worm-hole.

Are you implying that I don't? Then you are mistaken. My doubts about BB have nothing to do with religion.

If a black hole implodes in a cosmic forest do any Martians hear ?

There's a slight qualification that should be made. Special Relativity assumes that no signal or matter can travel faster than the speed of light in a vacuum.

This leaves open the possibility that space itself can expand at "super-luminal" rates, as is proposed in the Inflationary version of Big Bang Cosmology, since there's no way to transmit a signal, and no matter is being accelerated in any local frame of reference, by the expansion of space.

[Tamberlane]

Theory says nothing can move faster than the speed of light.

There may be elements of the universe that can travel faster than the speed of light, but our current theory does not allow acceptance of their existence, if they do.

Actually the ToR only rules out acceleration past the speed of light. Theoretically there could be entities that came into existence at a higher speed, and which from our point of view travel backwards in time. Such (hypothetical) entitites are known as 'tachyons'.

How about "near" a nearby galaxy?

[Prophet in the wilderness]

I had the same thought, maybe they are viewing it through some kind of tunnel that is letting the light from the quasar to go through the galaxy.
