If there was a time machine...

[Wickerman]

If any form of time travel ever becomes a reality, it will be an image only thing.
When you think that looking through a telescope at something in space, say 120 light years away, you are seeing it as it was 120 years ago.

Funny you should bring this up, I was musing along similar lines myself.
Time travel into the past does contravene the laws of physics, but into the future is consistent with the laws of physics. It all depends on speed.

However, although we might not be able to go back in time, the ability to view the past just might be achievable one day.

Everything vibrates at a given frequency. On the frequency band at the low end we have audibility - radio waves. At the high end we have light. Whether we 'hear' or 'see' depends on the frequency of the wave.
We, as humans, vibrate at a particular frequency too.

The ability to isolate that frequency and track its movements just might not always be in the realm of science fiction.
Today's science fiction is tomorrows science fact.

Imagine an archaeological site where we dig down removing the layers of strata, like peeling back the skin of an onion. Now, consider a satellite positioned over where Millers Court once stood which might be able to identify all the millions of frequency tracks which have passed through that location over the decades.

Today we possess surveillance satellites which have the ability to see through buildings, its a heat trace certainly, but this technology exists.
A frequency trace would have the same ability, there would be no details, you could not identify who someone is, but you might see activity to understand what actually occurred at that location.
Dating the frequency trace might be a problem, you would have to tie the activity to the known witness testimony.

So no, visiting the past should not be possible, but viewing the past, well, not in the near future that's for sure but, never say never!

Sorry for the digression..

Just don't ask me to do the maths for it, Jon!

Chapman, most definitely. That's the one that's always spooked me the worst. Kelly's death was far more gruesome, but there's just something about poor old Annie being murdered in someone's backyard, right under all of those windows, and Mr. Cadosch walking by right on the other side of the fence, unawares.

Catherine Eddowes. It wasn't the first murder nor the most gruesome, but its location, Mitre Square, has always drawn me in.

Did any of the witnesses ever testify as to whether any of the crime scenes were known "hook-up" spots favored by specific prostitutes? I wonder if Jack selected the locations or his victims did. But that is a whole other topic...
