Hello π fellow Nostriches!
The galaxy JO175, 650 million light-years away.

Wonder if they have bitcoin?
You know that is fake right?
I have seen this kind of stuff by my own telescope, so I believe in this shit π
Think about it for a second, the amount of energy needed to make that light travel 650M light years but it is not enough to burn everything in the vicinity? π
The sun is only 93M miles away and earth is burning up because of βclimate changeβ and you are talking about an entire Galaxy that emits enough energy to light up the sky 650M light years away. Think about it rationally, how is that even possible? π
Actually, light can carries enough energy to burn objects in its path, regardless of the distance it travels. However, the amount of energy it carries is determined by its wavelength/frequency, not distance.
For instance, we can even see the Andromeda Galaxy with our naked eyes, that is also 2.5 million light-years away, which proves that light can travel vast distances without causing damage.
If E=mc2 is true, then the amount of energy needed for something to travel at the speed of light is infinite! Now imagine the energy needed to sustain that speed for 650M lightyears. For you to say, the amount energy needed to create that light is large but not large enough to burn every other galaxy in it vicinity is just not plausible. Either the galaxy is not 650M lightyears away or E=mc2 is wrong or both could be wrong π€·π»ββοΈπ
Firstly, it is impossible for an object with mass to travel at the speed of light, Light does not carry any mass in the traditional sense, as it is composed of massless particles called photons.
The energy needed to create light is not related to the energy needed to sustain a certain speed.
The energy from a galaxy's light is spread out over a vast distance and is not concentrated enough to cause any significant heating or burning of nearby galaxies.
And also we not observing these faraway stars & galaxies using normal light.
But I respect your opinion, I may not agree with it but that's a beauty freedom.
You are regurgitating what they told you without questioning how rational or logical they are but if that makes you happy, carry on π
Sorry to butt in, but I think what iefan means is that the formula is EΒ²=(mcΒ²)Β²+(pc)Β².
E=mcΒ² is only a special case of that: when an object is not moving relative to you and it has mass.
Light has no mass. And thatβs why the special case for that is E=pc.
So no, E=mcΒ² doesnβt always hold true. Unfortunately physicists have failed to explain that clearly to us laypeople. Alas, much lamenting among them about this confusionβ¦
#[3],
What kind of telescope π do you have?
I built a 12.5" aperture reflecting scope back in the '80s, and still use it. I too have seen many beautiful galaxies with my own eyes. On of my favorites is M51...ππππ
Even at 650 million light years away you would arrive instantly if traveling at lightspeed. Ofc only the spaceship would perceive it as instant. This is due to time dilation. Large and small. Far and close. Long and short are just ambiguous illusions ππ
650M light years means you need 650M years traveling at lightspeed to reach here. How they figure it out. No one knows π€·π»ββοΈπ
Still in awe every time I see these kinds of images. Canβt even imagine the scale of life in that one little spot in the sky π€―
It's mind-blowing that as humans, we can never fully comprehend the scale and vastness of space through pictures & even in-person. Our brains simply can't process it, which is a sobering thought.
beautiful, hope there's another multiverse version of me doing the same nostr thing there.
