"Is one second on earth same As elsewhere in the universe?"
No, it is not

if time is different in other places in the universe,
then units of time are also different

astronauts who travel in space age at different rate than those on earth, therefore the "second" is different

In our everyday situations on the Earth, a second experienced by you will be the same as a second experienced by someone on the other side of the Earth.

Even when we put a satellite up into space and had it moving at a very fast speed around Earth, and brought it back down to Earth after quite a while, the discrepancy in time was so barely small it barely registered with our technology.

So, "yes", although the time can slow down if you move very fast, you need to move VERY fast (think "warp factor 0.9"). Unfortunately, you would be crushed to a pancake, and wouldn't survive.

the premise of the thread is not asking about "around Earth" or "the other side of Earth"
it is asking about "elsewhere in the Universe"

If a second were different somewhere else, then presumably the electromagnetic radiation emitted by atoms would change with location. But that hasn't been observed, other than what is explained via the doppler effect. Astronomers have looked for variations in the known physical constants with distance and location, but they have found no indications of such. If there were such variations at the start of the Big Bang, then it was probably smoothed out by cosmic inflation.
