Mysterious radio signals from deep space detected

[Duane 3NE 2NR]

Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada.

The precise nature and origin of the blasts of radio waves is unknown.

Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away.

Such an event has only been reported once before, by a different telescope.

"Knowing that there is another suggests that there could be more out there," said Ingrid Stairs, an astrophysicist from the University of British Colombia (UBC).

"And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles - where they're from and what causes them."

Very cool stuff.

radio waves travel through space at the speed of light, and those are being detected from 1.5 billion light years away. Whatever made those radio waves is long gone or very different from what it was 1.5 billion years ago

odds still 50/50 on them having hyper-drive.

We know who did not do science at O' levels

War of the Worlds type of reporting. Buzz words. Unfounded speculations.

Up to 10 000 FRBs occur everyday. It's only detected when a radio telescope is pointed directly at one, coincidently. It's not a rare or astounding event. It's just hard to detect because we're now being able to find them with newly developed radio telescope technology and techniques. And since they have all been extra galactic so far, they're probably a phenomenon like GRBs. The same sort of coincidence happened when we first detected GRBs with Vela satellites. A collapsing black hole perhaps, or black hole collision with a neutron star.

GRBs are scary. If one hits earth all life goes extinct. No warning. Speed of light. Probably happened once before in earth's history.


Zetski you seem to know nothing about the EM spectrum and boasting about it.

When he say radio I was thinking sound waves... I'll take the L

Maybe that's how the dinosaurs went extinct maybe?

[maj. tom]

Further back than the dinosaurs.

not very interesting.

A light year is a measure of distance not time btw

Thanos is coming...mark my words!!

[Ben_spanna]

Lmao- this morning on radio they were saying that they hope of Aliens visit Trinidad that they had their spaceship inspected or they will come all this way to get charged or towed.

Or robbed and killed.....

What speed do radio waves travel through space at?

Ummm speed is DISTANCE over TIME. A lightyear is a unit of astronomical distance equivalent to the distance that light travels in one year.

If it originated 1.5 billion light years away and travelled here at the speed of light, how long would it have taken to get here?

Lol so like how long did those waves take to reach earth then?

Might as well.

assuming the signal source to be static in the vacuum at it's initiation and that it traveled consistently at the speed of light directly from it's point of origin & straight to this big blue marble & that it there were no events or objects that would potentially slow it's travel, it'd take 1.5b years
however,
Their causes as well as their point of origin is unknown, so this introduces a few potential variables into the equation that could have either lengthened or shortened the time those waves took to arrive at this location from their initial outset. Currently, it's a lot of theoretical estimation as regards how long they took to arrive here and their point of origin, & that's why I pointed out that a ly is a measure of distance, not time. In essence, that covers the distance/time it took to get from there to here, but we do not know for certain that the signals actually started there & not further away or nearer.
All I'm essentially saying is until the signals source/s are identified, all the conjecture of how long they took to arrive here from their source is just that, conjecture, & that the use of parameters such as time can only be applied so far.

If we are looking at an object ~1.5 billion light years away, the image we are seeing is ~1.5 billion years old, not so?

My point is if science shows the waves came from 1.5B light years away, then it's a very old signal.
