Two stars will collide in 2022 in an event that'll be visible to the naked eye, astronomers predict

[hahahanoobs]

Dry your tears, put on your big girl pants, do better next time.

^Claims to have many degrees. Has the perfect opportunity to show off those degrees. Let's us all down with this:
If it's 1800 light years away, then technically, it's already happened - we just haven't gotten the light so that we can see it - yet.

Author did a far better job:
(well, not technically right now as the sky largely serves as a time capsule of events that happened many, many years ago due to the vastness of the universe)

And as long as we are stuck in Earth's space time, we will never understand whether that is true or false.

Gravitational waves are quite an extraordinary piece of evidence for that.

For once I can agree with you.

You've got to look at this like schrodinger's cat... you don't know they will collide, because you havent seen it yet... You have no proof they will collide. see what I did there

Edit: you have no proof that they have collided, because we haven't seen it yet, because they're 1800 years time-distant away from us

And as long as we are stuck in Earth's space time, we will never understand whether that is true or false.

But hasnt this theory already been proven? I mean... what did Einstein do? lol Maybe I'm wrong, wont be offended if you correct me.

Yeah well, that should read, "you have no proof that they have collided, because we haven't seen it yet, because they're 1800 years time-distant away from us".

(You do remember saying you wouldn't be offended if someone corrected you, don't you)?

Thanks. Done. I'll be the first to admit I need some help wording things out properly.. or maybe I need to sort my thoughts out better. lol

The sky is falling...

OMG - - THE SKY IS FALLING run run run

I understand exactly what parallax, time dilation and light speed's implications are when talking about celestial events.
.

Let's be clear here, the speed of light isn't exactly the speed of light. Light moves at "the speed of light" because it's particles have no mass. The speed of light is actually the speed of information and influence. SpaceTime is not uniform. Simply because we can predict that it happened in a certain point 1800 years ago does not mean that it happened everywhere 1800 years. Things do not happen happen in the past, they are always happening at different points in space.

SpaceTime is a whole lot weirder than most people care to understand.

Here's the problem.

If light has no mass, then they shouldn't be effected by gravity.

They are though.

If light had no mass at all - it should be able to move at infinite velocity like Tachyons.

And that's what I was trying to explain. The speed of light is not the speed of massless particles on a vaccum, it is the speed of influence and information. They are not effected by gravity, spacetime is. Light is traveling in a straight line through curved spacetime

Excuse me? Tachyons move at infinite velocity? There is no valid scientific proof of that. Perhaps you should consider employing a good therapist. You should really educate yourself on topics which you do not understand. And once again, I caution you to stop embarrassing yourself pretending to know what you do not. Just because you voted for Trump does not make you the brightest bulb in the pack or confer upon you special rights by saying, falsely, "I know what I am talking about and you don't".

In addition, photons are considered to have relativistic mass since they have energy. It is spelled out in a simple to understand means here.

Really, dude. Stick to your utub channel. You will get more out of it than recognition for your superiority in the TS Forums. Of course, I enjoy laughing at your posts since they are rifled with obvious inanity
