Am I going to absorb 4 years of light data from Alpha Centauri or is it just going massively blueshift?
Relative to what? The gravitational force between the voyager probes and sun (and voyager probes and planets and everything else in the inner solar system) is lower than it was in the past.Isn't it true that the voyager probe feels less force from relative accelerations
What?This tells me that time is kind of more like constant
What?but the forces in nature like gravity and the energy from our sun create little time-warp-zones that bind the action within them.
?Or to paraphrase, lightwaves are the fluid of time.
This is true, and it is already taken into account. You have to do the same for exoplanet searches and even position measurements of stars.Pulsars pulse at atomic clock precision, shouldn't there be a slight oscillation in pulse rate over the course of a year based on the rotation of the Earth depending on if we're swinging towards the star or away from the star?
No, this would violate General Relativity.Basically it would take more acceleration in deep space to feel "1 G force".
Please provide a source for this claim.These are test results returned from the Voyager probe.
I don't know the numbers, but I assume it's something like 10.1m/s^2 or more acceleration to feel a G
DaleSpam said:EDIT: actually, I just did the numbers. That is a sustained acceleration of 411 g for 1 week, and that is assuming that you don't want to stop at Alpha Centauri, just fly by at a shade under c.
Sorry, that can't be right. 1 week on Earth's clocks -> less than 1 week on an on-board clock.mfb said:[..] If you take a clock with you in the spaceship, you will get a different value (4 years + 1 week). [..]
Ah yes of course! (I have not been drinking... could this be due to lack of sleep? )mfb said:The "1 week" is the on-board clock and corresponds to 4 years on Earth (and the rest frame of alpha centauri). The 4 years correspond to the 4 years before where the spaceship was at rest on earth.
Alpha Centauri is the closest star system to Earth, located about 4.37 light years away in the constellation Centaurus. It is a triple star system, consisting of two sun-like stars, Alpha Centauri A and B, and a smaller red dwarf star, Proxima Centauri.
The distance to Alpha Centauri is about 25 trillion miles (40 trillion kilometers). With current technology, it would take about 30,000 years to reach Alpha Centauri. However, if a spacecraft could travel at the speed of light, it would take about 4.37 years to reach Alpha Centauri.
This is not currently possible with our current technology. The fastest spacecraft ever launched, the New Horizons probe, would take about 78,000 years to reach Alpha Centauri. The only way to travel to Alpha Centauri in 1 week would be to significantly advance our propulsion technology, such as developing a way to travel at or near the speed of light.
Aside from the technological challenges, there are also physical and biological challenges to consider. The spacecraft would need to withstand extreme radiation and temperatures, as well as navigate through the vast emptiness of space. The crew would also need to deal with the effects of long-term space travel, such as muscle atrophy and bone density loss.
If we were able to develop the technology to travel to Alpha Centauri in a reasonable amount of time, it would open up the possibility of exploring and potentially colonizing other star systems. It could also lead to new discoveries and advancements in our understanding of the universe. Additionally, it could serve as a backup plan for humanity in case of an extinction-level event on Earth.
