# Mark and time travel

Sun 28 Jul, 2013 10:50 am
Of course time travel in a forward direction is well proven but the effect of gravitation still remains a kind of mystery (to me anyhow)

One Mark in another thread speaks of time travel with reference to the center of an explosion, intriguing.

http://able2know.org/topic/217655-2#bottom

Of course at that instant the concentration of matter might engender a local increase in gravitation which would indeed slow any clock capable of withstanding it but wouldn't the diff be very slight

….suggesting another q: If gravitation slows a clock, might a high pressure not also

....and how about the effect of acceleration, terrific I'd think near the very center

Pressure, no.

But both gravity and acceleration cause the effect interchangeably.

As for slightness, it depends on the degree of acceleration and degree of gravity.

Spend some time hovering just above the event horizon of a black hole (careful not to fall in) and the gravity will give you a time slowdown similar to what you'd get if you had accelerated to near light speed.

Thanks Ora, I thought probably not

So I had been led to believe

Of course it does but specifically I'm curious about the center of an explosion where owing to the concentration of matter there might be a gravitational effect tho I imagine it to be very slight; while I've no idea the effect of acceleration on the particles

@dalehileman,
It would appear slight, externally, but, internally, relatively universal.
You are overlooking the 'implosive' effect of the explosion.

I presume that you mean time has slowed down significantly for a particle near the center. I'd have to take your word for that Mark as I'm hardly a physicist. Yet this is the first I've heard

That's what I mean by "concentration of matter"

@dalehileman,
Dale...
Create a 'substate' vacuum, in a FLASK even, and it will slow 'progression'.
Heat/Cold will sustain itself 'beyond' measurable dimensional parameters.
Just quantumise this state.
Isn't difficult.
