BTW, the European Southern Observatory (ESO) agency is building a 39.3-metre-diameter telescope at the moment in Chile. The "Extremely Large Telescope". First light is planned for 2028

But 30 meter is not bad either.

1 second last 1 second for you. Always. But only in your time frame. It doesn't matter if you are in open space, on a planet, near or in a black hole.

There is no "universal time" that you can take for reference. You can only compare different time frames.
