Science Mysterious object just 4,000 light years away from Earth releases a giant burst of energy

[SlyPokerDog]

Mysterious object just 4,000 light years away from Earth releases a giant burst of energy three times an hour – and is unlike anything astronomers have seen before

• Mysterious object unlike anything ever seen in space discovered by astronomers
• 'Spooky' item was observed releasing a giant burst of energy three times an hour
• For one minute in every 20 the discovery is one of brightest objects in night sky
• Object may be a neutron star or a white dwarf with ultra-powerful magnetic field

So I have always wondered.... is a light year the same as a me year? If I wanted to travel 4,000 light years, would I need to live 4,000 me years?

I think you would have to do it at the speed of light for it to be a me year, otherwise it will take you much longer.

A "me" year is a measurement of time. A light year is a measure of distant.

That said, at the speed of light it would take just under 40,000 years to travel a light year so, to travel 4,000 light years it would take 160,000,000 years at out current ability of speed.

Not quite. To an observer on Earth. But time dilation at near light speed means the traveler ages much less.

I wonder why they would use a measurement of time to measure distance? Why not a light mile? Light meter?

Right. That time would have passed here, but the traveler would experience it differently, as a much shorter duration.

Using the term year can be confusing. A light year is how we measure the distance between stars as observed here on Earth. It's the distance, not the speed (and therefore time)that light travels in one Earth year. Once we determine the distance, we determine how long it would take to travel, thanks to Einstein.

There are light minutes and hours. The planets in our solar system are light hours away.

 

[donkiez]

They kind of do that in the PNW. It's pretty common to say things like Seaside is about an hour away from Portland.

wut?

It's all relative but for us on earth the time it would take something traveling at the speed of light to travel one light year is one calendar year. That's why it's called a light year. It's about 6 trillion miles.

However if someone was theoretically traveling at the speed of light the amount of time it would take that person is 0 seconds. As long as you're traveling at the speed of light time stands still. But nothing with mass can go the speed of light.

this is the part that hurts my head. How is it zero seconds for the person traveling? Does light from a distant star experience no time even though for us it took millions of years to get here? Then there is the whole tounge in cheek question of, if I am on a train going the speed of light and walk forward how is that not faster than the speed of light? Totally ignoring the mass part of the equation of course.

One light year is best described by how long Mrs. @THE HCP lasts. And it’s 100x longer than any of you bitch-ass nerds do. 300x longer than HCP.

No, you're not understanding how it works.

Time is relative to those who are experiencing it.

To use your example:

@THE HCP and wife are making love...

To Mrs HCP this is the most boring night of her life.

To HCP this is the greatest 3 mins of his life.

In reality, the sex only took 30 seconds.

To Mrs HCP this is the longest and worst week of her life.

In reality, the sex only took 30 seconds.

#Bam!

I still don't get it. Do you have any graphs or other visual aids?

Yeah but it's funny because that isn't always just about distance. Sometimes something that should only take 30 minutes to drive actually takes an hour because of traffic. So time is relative as a measurement of distance

Hey you guys, next time don't piss me off.

Ask Einstein, he's the smart ass in here.

There are light minutes and hours. The planets in our solar system are light hours away.

How can the planets be light hours away when the sun is only 8 light minutes away Granted Neptune is 4 light hours away but that's Neptune for crying out loud and what maniac wants to vacation there?

 

[Phatguysrule]

The planet with the closest average distance to Jupiter is Mercury.

Mercury is also the planet with the closest average distance to every other planet in our solar system.

You've spent too many light years on this analysis.

 

[crandc]

Since an object with mass can't travel at light speed you would experience time. Just a lot less at near light speed. Walking on near light speed train would not be more than light speed. Light does not "experience" time. It is counter intuitive.

Ok

Saturn is a light hour away

Uranus is about 2.5

Neptune is about 4

And Pluto though it's now considered a dwarf planet is about 5

Excuse me,

At our current ability of speed.

Time to give it the Pluto treatment in the name of social distancing.

Time slowing down the closer you get to the speed of light explains why you can't exceed the speed of light.
