Reply to NASA Missions study what may be a 1-In-10,000-Year Gamma-ray Burst, the most powerful class of explosions in the universe. On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. by ICumCoffee
will this cause the neutrino detectors to see an increase?

Somewhere between 657 million years and forever.

Not accounting for spatial dilation due, of course...

For perspective, any light from earth reaching it today would pre-date essentially all animal life in the history of the planet.

At that distance, cosmic expansion may keep them from ever meeting, even if they kept coming at one another. Space is weird.

Yeah a light year is simply the distance that light travels in a year.

Oh, ok! Thank you for answering (and being patient with me for not knowing this stuff)!

Even if earth and the black hole were heading towards each other at the speed of light (can’t go any faster), it would take hundreds of millions of years to meet in the middle.

I meant light travel! Nothing else. Thank you :>

If moving at the speed of light (and we’re assuming the movement of the earth is insignificant), it would take, well, 657 million years.
If you didn’t mean light speed travel, we need to know what speed you’re intending.

Oh! Well I'm not sure how fast. I read this article that said a blackhole is facing us and apparently it's a blazer (I don't know what that means I'm knew to space stuff) and it says it was 657 million light years away and I was wondering, if it were to come towards us, how fast it would be, but since I don't know the speed then I'm not much help. Sorry.

It depends entirely on how fast that something is moving toward the Earth. You only specified a distance, but not a speed.

It wont. It's beyond Laniakea, itself not gravitationally bound.

you move it so all those consultants and contractors can get a piece of the pie. That's the only reason.

Wait so the moon has natural formed glass beads?
