Traveling to Andromeda in 2 Months with a Spaceship

AI Thread Summary
Traveling to Andromeda in a spaceship that can accelerate to near light speed (c) raises questions about time perception due to relativity. From the spaceship's frame of reference, the journey could seem to take only two months, but relativistic effects mean that less time would pass for the travelers compared to observers on Earth. The discussion emphasizes that no material object can reach the speed of light, only approach it. The relativistic effects would significantly alter the perceived duration of the trip for both the travelers and those remaining on Earth. Understanding these concepts is crucial for grasping the implications of high-speed space travel.

Suppose I have a spaceship that can accelerate to c in one month of acceleration/deceleration of month and I want to travel to Andromeda. From my frame of reference wouldn't my total travel time be two months?

No material object can accelerate to c, it can only get close to c.

You may want to see The Relativistic Rocket [1] for details on how to calculate this and what the results are.

Assuming this means "very, very close to c": 1 month in which system? For the ship: then sure. For earth? Then the ship will experience even less time.
 

Thread 'Does it make sense to build new radio telescopes?'

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?'

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...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
