Reply to The Eta Carinae nebula from my back yard - it's both brighter and 4x larger than the Orion nebula but is hidden in our Southern skies by EkantTakePhotos

It's brighter and 4x larger than the Orion Nebula but because it's only visible in Southern skies the Eta Carinae Nebula doesn't get as much love as Orion. At 7,500 light years away it's a huge nebula that is close to the Southern Cross and visible all night.

All shot from my back garden in Christchurch, New Zealand (Bortle 6) - A total of 48 x 300s light exposures were taken with 60 flats, 60 darks, 30 Dark Flat frames for calibration for a total of 4 hours of light data and just over 9 hours of total integration time.

This image was taken with the following gear:

  • Camera: ZWO Asi533mc Pro
  • Scope: Williams Optics Redcat 51
  • Mount: iOptron CEM26
  • Guider: iOptron iGuider
  • Filter: Optolong l-extreme

I post shit like this all the time on Insta (@EkantV) and Facebook (EkantTakePhotos) but I'm usually just a sarcastic dick on Twitter, so don't follow me there.

Tired Light, Variable Speed of Light, and Steady State are all theories that I personally believe got thrown out too quickly. Some because YEC hijacked them to try to justify a 6 thousand year old Earth, making it career suicide to investigate as a serious researcher.

James Webb is hopefully going to make big changes. I find it notable that very few of its observations are being published soon after they are made. They are finding fully formed galaxies way too early, and having a hard time explaining it (dark matter is always there to rescue the BBT though).

All I can add today is that science can send a robot to Mars and transmit pictures for you to view. Science can calculate Time, Velocity and Position to get a camera to go past Pluto and transmit pictures for you to view. Let's start from this.

Ive seen articles from my feed saying that there is more doubt than before, I def am not making it up or claiming that ive come to this decision based on info from it, just regurgitating what ive read.

Also agree with u it more than likely is just click bait so guess I shouldn't have said anything. Hate the downvotes just for saying something I read, not wrote

The concepts you are thinking about is are some of the most interesting ones in all of science.

How could the universe possibly be eternal? And if it is not eternal, Where did everything come from? What happened before it was created?

One of the answers is that it appears time is something that only has meaning inside a four dimensional, space-time universe, such as the one we live in. In other words, where there is no space time there is no time.

This is mind boggling but there are many things about nature that are extremely weird and counterintuitive but proven true.

For example, did you know that Time runs more slowly under certain conditions?

I don’t mean that something physically is wrong with clocks in certain parts of space. I mean that time actually ticks at a different rate if you travel fast - like close to the speed of light.

This short cartoon explains it nicely:

Or something you probably do not know yet that has also been proven is that if you have an absolute vacuum that is 100% empty of all molecules and atoms of any type, at the tiniest, quantum level, tiny particles, both positively and negatively charged, are constantly popping into and out of existence.

The science of the Big Bang is that we don't know much about that.
But it looks like the Universe have been much much smaller and denser at one point back in time.
The best evidence for that so far (as I understand) is the background cosmic radiation.
