I heard that the universe is constantly expanding, well if the universe is constantly expanding then matter and energy must be expanding with it, so if a person was able to travel back say 5000 years in the the past would his atomic mass be altered do to the fact that the universe of 5000 years ago would be more dence than it is today, if it was altered what would the results be?

The universe is expanding, but I never heard of matter and energy expanding. It is just becoming more sparse.

Do we taste the reality of fact? This for the light of the encounter disrespects the fact that time is not a bidirectional dimension. If he was 5000 years back in the past, the mass would be the mass it was 5000 years ago. How could the mass be funny mass. Could the mass of a 5000 years ago world be today's? How could that be possible? If it were, then you wouldn't be 5000 years back in the past.
Mass is time or timing or timed or a timer. For if you were to have timed for a 5000 year ago time, it would be a 5000 year ago timeing. How could the timer be of the present time?

I think that space is expanding, meaning more empty space between areas that have mass and have gravity that effects it's local surroundings. Not all Galaxies are speeding away from us, Andromeda will eventually collide with the Milky Way in the far distant future.
If what you suggest were to be true, as you go back in time, you, and everything around you would shrink at a uniform rate so you would not even notice it, and by the time you arrived, you would have shrunk down to the size at the same rate as any meter stick and you would be the same height and weight, presumably, as when you left.

The universe is expanding but in reference to point masses. Galaxies are expanding from each other but the galaxies are not getting larger. The only energy that is spreading is the residual from the original blast. All other energy is radiating from masses.

Mmmmm, i think you may have something here, i don't think you have to go back 5000 years, perhaps 30-40 would be enough, middle aged American womens fat lardy arses seem to be expanding at an ever increasing amount, even in the UK we can see this effect, look at Dawn French, Vanessa Feltz and Fern Gully.

It is not expanding on an individual basis..it is expanding away from a central point.

5000 years is such a small drop in the ocean, that you probably would never measure it. However you raise an interesting point. My only thought is that everything is relative.

IF (BIG IF) ONE CAN TRAVEL TO THE PAST,,, THE UNIVERSE IS DENSER ALRIGHT... BUT TAKE BILLIONS OF YEARS IN THE MAKING... NOT JUST THOUSANDS...

maybe...
or ther might just be less space in the universe
