AI Thread Summary
A powerful telescope launched away from Earth and accelerated to near light speed would not allow observers to see into the future. Instead, while only a few years would pass for the telescope, 2,000 years could pass on Earth. This means the telescope would observe Earth as it existed 2,000 years later, but the observers would be long gone. The concept highlights that the telescope would effectively be a method for viewing the past rather than the future. The discussion clarifies the implications of time dilation in relation to high-speed space travel.

like the hubble, but much more powerful, away from Earth and was able to accelerate it to near the speed of light by either gravity or some future ion accelerator. Would everything on Earth speed up for the observing telescope and hence allow us to see into our own future?

No, It wouldn't
 
From the telescope, let's say a few years would pass but say, on Earth 2,000 years would pass. When the telescope looked at the earth, it would be a few years after you launched but things on Earth would be 2,000 years later. But its not "seeing into our future" because the Earth is 2,000 years older and the people who sent the telescope into space are now 2,000 years old (dead).
 
Right, for the telescope everything would slow down, not speed up. This would be an excellent method for seeing into the past!

Thank you for the insight!
 
Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
